Orions - Ur'eon/Kolari

Table of Contents:




Members

  • Sexual dimorphic

  • Females - average 1.5 meters and 60 kgs.

  • Males - average 1.7 meters and 70 kgs, but have been observed up to 2 meters and 80 kgs.

  • Subspecies
    • Ruddy or Orange - approximately 1-3% of the population.
    • Grey - listed as approximately 1-3% of the population but seem to be rare.

Respiratory System

  • Two lungs occupying the thoracic cavity. A diaphragm is present.

  • Right lung is divided into four lobes as compared to a humans three lobes.

  • Left lung is reduced to two lobes to accommodate the heart.

  • Unlike human physiology, the lungs wrap further under the rib cage to the backbone and slightly further to the sternum providing better oxygen intake.

Nervous and Execratory System

  • Nervous system is organized similar to humans.
    • The olfactory nerve and attendant mapping to the amygdale of the brain is much more developed.
    • In males especially there are major connections directly between the amygdale and the nucleus accumbens.
  • The organization of the kidneys (two), bladder and other execratory system functions are almost identical to human counterparts.

Digestive System

  • Though similar to humans in overall organization, there is a secondary organ (referred to as a crop) that is highly vascularized and connected by a duct into the upper intestinal system.

  • This crop functions as a holding area to collect from the blood stream the production of simple carbohydrates that the chlorophyll in the skin produces.

  • It is thought that this combined with a slightly larger lung capacity, the oxygen production of the chlorophyll located in the skin to give Orions their extra endurance.

Visual System

  • Two eyes
    • Simple non compound eyes.
    • However, the construction is different from most other humanoid eyes in that the corneal covering does not form a lens. Instead, Orion eyes are considered to be reflector eyes in which the interior is lined with reflective material which then reflect the image to a focus. This allows attenuation of the amount of light hitting the optic nerve to be attenuated which was an adaption to the intense light of the blue white sun that was the origin of the species.
    • An interesting aspect of this construction is that looking into the eye through the pupil one 'sees' exactly what an Orion would perceive.
    • Orions are capable of perceiving light from 460nm to 850nm. Thus they cannot perceive deep blues, but can see into the near infrared range. Again an adaption to avoid the intense UV of their native system.
    • Due to the construction of the eye, it is the principle reason that most ocular compounds such as Retinax V do not work.

Circulatory System

  • Haemocyanin - copper based

  • The distinct colour ranging from greenish to goldish is both a product of the copper atoms being bound in heme rather than prosthetic groups and is based on replacing the magnesium of the chlorophyll found throughout the skin tissue with copper.

  • Hearts - four chambered based on bilateral symmetry. However, like Terran birds the aorta bends to the right rather than to the left.

Skeletal System

  • Orion skeletal system is humanoid and little to remark on from its Human counterpart other than being somewhat denser in the males than in human males.

  • The denseness of the male bones results in increased strength for the remarkable musculature that is present in many but at a reduction in the ability to provide easy replacement of blood cells.

Skin

  • Orion skin is remarkable in the presence of chlorophyll. This is also an adaption to the intense UV light of their native solar system.

  • The subspecies mentioned above are due to the result of the non-formation of the chlorophyll and in the Ruddy Orions allowing the Anthocyanins and Carontinoids to show through. The Grey Orions show a defect in the production of all pigments.

Reproductive System and Reproduction

  • Internal insemination between males and females.

  • Males have bilateral testes and external phallus.

  • Females posses a vagina, cervix, uterus and ovaries similar to Human.

  • Unlike Humans, females while undergoing menopause continue to be able to make estrogen and progesterone in normal quantities resulting in less effects of aging than in their human counterparts.

  • The females are able to control their own fertilization through techniques that modify their considerably complex endocrine system.

  • The normal gestation time in Orions is approximately the same as in Humans.

Endocrine System

  • The endocrine system of Orions is organized similar to Humans but with some important differences.

  • Both male and female Orions secrete various pheromones. The most famous of which is a sex pheromone.

  • Though the sexual pheromone seems to be the default pheromone given off, the linkage with the amygdala and neuronal connections to the rest of the limbic system results in pheromones that can be produced based upon emotional moods.
    • This accounts for the noted that calmness results in-group calmness, fear in group fear and so on depending on the general mood.
    • It is thought that this group pheromonal production allows for the society to function better.
  • In Orions the pheromone release is through a special gland the Androconia gland.
    • In females this organ is particularly pronounced.
  • The attendant reception in both sexes is through the Vomeronasal organ (VNO). The VNO is the first stage of the accessory olfactory system, and contains sensory neurons that detect chemical stimuli. The axons from these neurons project to the accessory olfactory bulb, which targets the amygdala and bed nucleus of the stria terminalis, which in turn project to the hypothalamus.
    • The males this organ is enlarged and has an abundance of neuronal ties. It is thought this is the reason that Orion males can become easily enraged and aggressive when exposed to Orion female pheromones.
    • Constant exposure induces a dependency on a particular pheromone trait and it is thought that this is why it has been said that the females enslave the males.

Metabolism

  • Endothermic

  • Body temperatures tend to differ from Human in being 10 degrees warmer when active and 10 degrees cooler when inactive.

  • Due to the rather lean nature compared to other endothermic humanoid females, female Orions tend to have several short sleep cycles rather than one long one.

Other

  • There was thought to be a subcaste of the Orion race that possessed animalistic qualities, giving rise to the legend of the "Orion animal woman". They were claimed to be less intelligent and behaved in a semi-animalistic fashion. It is unknown if these traits indicated a subspecies or a genetic alteration or were simply a myth based on their legendary sexual appetites, violence and savage Orion behavior. It may have derived simply from a lack of educational opportunities.
