Vulcans:

Cardiovascular Information

Average Blood Pressure: 80/40 (Systolic/Diastolic).

Average Pulse: 242 BPM (Beats Per Minute).

Blood Coloration: Green dilated blood vessels.

Vulcan blood is a copper-based compound and is green in colour. Copper-based life aids in the utilization of oxygen under the low atmospheric pressure, low oxygen conditions on Vulcan. Blood cells are biconvex in contrast to the concave cells of Terrans. This convex shape also aids in cooling individual blood cells, the entire blood stream, and finally the entire Vulcan body. Another feature of the Vulcan blood cell is its ability to take in and store large amounts of oxygen in a thin, oxygen-poor atmosphere.

Neurological Information

The Vulcan eye is protected by a clear inner eyelid (nictating membrane) that filters out harmful radiation, heat and dust, all elements present on Vulcan. The eye itself if very similar to the human eye except for its range of colour differentiation for high frequency waves (the ultra-violet range) which is less acute, while night vision (low frequency waves in the infra-red) is more acute.

Brain same overall structure and size (1600 cc) as that of the Terran midbrain area larger and more complex.

Respiratory

The Vulcan nose is very similar to the Terran nose, but not nearly as efficient an instrument of smell. It is, however, highly adapted to filtering air and passing it on to the lungs. Since 60% of taste is in the sense of smell, Vulcans have a notorious lack of taste sensation.

Their lungs are somewhat larger in size than Terran.

The alveoli are 75% more elastic than Terrans (making them better oxygen absorbers).

Gastrointestinal

Vulcan excretes only 50% of the liquid matter that the kidney processes.

Hormonal System

The ductless glands of the Vulcan are, unlike those of Terrans, under self-control and not autonomous systems. The individual adult Vulcan can regulate the amount of adrenaline and so speed up or slow down their internal systems in response to environmental conditions.

The thyroid can also be controlled to change metabolism. By stopping the flow of thyroxin and adrenaline, the Vulcan can go into a state of suspended animation, very much like the trance state of the Indian Fakir. During this state of suspended animation, the Vulcan can command bodily resources (blood, lymph etc.) to repair damage. Thus, the Vulcan can control bodily functions that are considered autonomous by Terrans.

Reproductive

Vulcan male is only capable of sex approximately once in seven years.

MUST mate every 7 years during pon farr.

Musculoskeletal

Males - lacking supraorbital taurus (bony ridges) above the eye like Terrans.

28 Teeth with no rear molars.

Dolecephalic (long-headed).

Skin

The Vulcan epidermis, unlike human outer skin, is a two-way moisture-proof shield. Not only does it act as a waterproof barrier allowing cells to live in a fluid environment even in relatively dry air, as does human skin, it also allows available environmental moisture to be extracted for use by the body.

Highly specialized cells in the dermis, known as hyalothermonic cells, permit more efficient body heat loss with retention of water than does human skin (because of an absence of these specialty cells). These unique skin properties, along with the absence of sweat glands, are necessary for Vulcan life, and explain the survival of the species in view of the environmental conditions of everyday life on Vulcan.

Miscellaneous

Average Height = Male = 2.0 meters (6'6"); Female = 1.7 meters (5'6")
Average Weight = Male = 70 kg (154.3 lbs); Female = 50 kg (110.2 lbs)

Body Temperature = 32.78C (91F)

Dispersion of heat through radiation (no sweat glands) in the hyalothermonic cells.

Average Life Expectancy = 250 Standard years.

Vulcans are almost always strictly vegetarian.

Special Traits

The Vulcan mind meld is a psionic technique normally employed only by Vulcans.  It is a deeply personal thing, part of the private life, and not normally used on aliens.  Melding is not telepathy; those in a meld share consciousness in a kind of gestalt.

Physical contact is required.  The initiator places the tips of his fingers at key locations on the head of the other participant.  This allows him to place pressure on key nerves and blood vessels to facilitate the link.  If successful, the link results in a merging of both minds essentially creating a single consciousness in two bodies.  Only the subject in physical contact with the initiator participates in the meld, others in the vivinity are not affected.

Melding carries some risk.  It can be physically debilitating for both parties.  The pressure changes can potentially aggravate existing conditions.  The melding results in some loss of identity, and can be difficult to break, especially when the subjects mind is powerful or dynamic.  After effects can be treated with the drug lexorin.

At the conclusion of the meld, each mind retains some knowledge of the other. 

It is possible to force a mind meld on an unwilling subject, but most Vulcans refuse to unless it is absolutely necessary. 

Susceptibilities

Pon Farr is an ancient drive that impels the Vulcan to return home to take a mate, or die. Neurochemical imbalance leading to nervousness, sleeplessness, outbursts of anger and violence... he can even become unaware of his actions. if nothing is done about it, the physical and emotional pressures will simply kill him

Pa'nar Syndrome is a Vulcan disease that results in the degradation of the synaptic pathways. It also affects the endocrine and immune systems. It is caused by a disruption of neuroelectric impulses during Vulcan mind melds performed by a Vulcan who has been improperly trained. It can be cured by a meld performed by an experienced melder.

Bendii Syndrome is a rare illness after age 200, causes loss of emotional control, which can be telepathically projected to others.

Klingons:

Cardiovascular

8 Chambered Heart as organ redundancy.

Lavender/Pink blood based on metal ion manganese content.

Respiratory

Three lungs.

Gastrointestinal

Two livers.

Musculoskeletal

Heavy chest plates, reinforced central nervous system (spine/skull)

Reproductive

Klingon pregnancies normally run thirty weeks, but with mixed species, gestation times are shorter. The odds against Klingon-human conceptions are rather high; however, when successful, Klingon and human metabolisms sometimes clash causing biochemical fluctuations in the mother, which may lead to fainting. Klingon traits remain dominant for several generations, even with a single ancestor, therefore a child even 1/4 Klingon will still possess forehead ridges.

After birth some Klingon infants may experience a pronounced curvature to the spine, which may be corrected for by surgery. This "defect" tends to run in Klingon families, especially among females. Federation medicine, fortunately, has advanced beyond that allowing an additional choice of treatment which involves genetic modification.

Miscellaneous

brak'lul - Organ Redundancy.  This means that all vital bodily functions have a ‘back up’, such as their two livers.  This organ redundancy has evolved in the Klingons due to the frequency and often severe injuries sustained day to day.

Often suffer from allergies, most notably the allergy to small furry creatures such as Tribbles.

They have no tear ducts.

Shattering the cranial exoskeleton at the tricipital lobe kills instantly.

Rop’nGor is a measles like disease that Klingon children can suffer from.

Trill

Neurological

Joined trill come up with two separate brain wave patterns when scanned using conventional medical tricorders.   

Special Traits

Twin columns of spots from forehead to feet.

Capable of hosting vermiform symbiont in abdominal cavity.

Susceptibilities

Interdependent host/symbiont within 83 hours

Isoboromine levels are critical if they fall below 50 and the symbiont will need to be removed from the Trill.  Isoboromine is a neuro-transmitter like chemical  that links host/symbiont brain patterns.

Symbionts are highly allergic to insect bites and toxins, nerve gasses and other chemical agents.

Joined Trill have slightly heightened senses of smell, taste and hearing.

Miscellaneous

The Trills basic physiology is very similar to Terran and should be treated basically as a Terran.

Bolian

Cardiovascular

Bolians are known for their Blue Blood.  Bolians have a blood chemistry very different from that of other species, especially Vulcans. If a blood transfusion is given from a Vulcan to a Bolian it would result in the death of the Bolian. There have been instances, however, when artificial blood was unavailable and existing blood cells were genetically altered for inter-species transfusions to be successful.

Musculoskeletal

Bolians are distinguished by a bifurcating (cartilaginous) ridge running vertically along their heads and bodies. They also have cartilaginous lining on their tongues that allows them to consume foods not normally palatable by many Federation races, including strong acids.

Skin

Their skin tone is generally blue, some may have dark blue bands on the head.

Reproductive

Intimate relations between Bolians and humans typically cause adverse effects to the latter, which may include fatigue, nausea and joint inflammation.

Bajoran

Musculoskeletal

Bajorans resemble terrans in appearance, and are distinguished by a series of four to seven creases across their noses.

Cardiovascular

Bajoran heart is mirrored along a horizontal axis unlike a terran heart which is mirrored along a vertical axis.  A puncture in the lower ventricle of the heart will cause instantaneous death.

Reproductive

Bajoran women gestate for only five months, forming an intricate network of blood vessels between the mother and the fetus. During the pregnancy, Bajoran women are frequently afflicted by bouts of uncontrollable sneezing.

Betazoid

Neurological

Betazoids reach rapid eye movement (REM) sleep at a different frequency from other humanoids.

Special Traits

Telepathy, most develop this ability in adolescence, a few are born with their telepathic abilities already active. Unable to screen out the noise of other peoples minds, these individuals generally suffer mental problems of varying severity.

Unable to read the minds of Ferengi, Breen, Ullians or Dopterians

Reproductive

Betazoids can cross-breed with terrans, although this often affects the telepathic abilities of the offspring and most commonly the children of such a union develop empathic rather than telepathic abilities.

Miscellaneous

Externally, Betazoids are among the most humanoid species on record and are outwardly indistinguishable from terrans in every aspect but one, the irises of their eyes are completely black.

Andorian

Cardiovascular

Intravenous injection impossible, must perform intermuscular injections instead.

Cobalt based blood

Miscellaneous

Most Andorians have a distinctive blue skin and white or silver hair. A sub-species of Andorians known as the Aenar have white skin; unlike the blue Andorians, the Aenar are blind and telepathic.

Andorians have a higher metabolism than humans.

Antennae

Andorians have on their heads two knobbed antennae which are used for balance. An Andorian is partially disabled and unable to fight immediately following the loss of an antenna, but is able to compensate within a day or so. The antenna itself can take up to nine months to regrow on its own, although the regeneration can be completed in around half that time with electrical stimulation and cranial massage therapy. The loss of an antenna is a humiliating experience for an Andorian to come to terms with.

Antenna movement apparently expresses feelings as well. An Andorian will sometimes point their antennae at a potential mate to signify attraction.

Susceptibilities

Andorians are very susceptible to high temperatures, an Andorian can lose 10% of its body weight in as little as two days in climates approaching the boiling point of water.

Cardassians

Musculoskeletal

Externally, Cardassians are easily recognizable by their two thick vertical neck ridges that recede back to the crown of the head and an inverted tear-shaped ridge in the center of the forehead. The ridge is thickest immediately above the eyes, protecting the eyes and making them look especially deep-set.All cardassians also have 2 secondary spinal cords on either side of their primary spinal column.

Romulan

Physically, Romulans are almost identical to their ancestors, having the same pointed ears and converging eyebrows as the Vulcans. Externally most Romulans differ from Vulcans in having prominent ridges of bone on their foreheads. Though identical in almost every way to their cousins, the Romulans lack the rigorous mental disciplines developed by the followers of Surak. They are a passionate people, easily moved to extreme emotions.
