Spinal cord tracts

Spinal cord tracts in Homo Galactus.

Spinal Cord – a long, thin, tubular bundle of nervous tissue and support cells that connects the brain structure to the rest of the nervous system in vertebrates. For most Homo Galactus, it is around 45 cm in males and around 43 cm long in females. Also, the spinal cord has a varying width, ranging from 13 mm thick in the cervical and lumbar regions to 6.4 mm thick in the thoracic area.

Although of Terran origin, this term is widely used by Union Exobiologists for any creature with a similar structure.
