spinal cord

Part of the central nervous system located in the vertebral canal continuous with and caudal to the brain; demarcated from brain by plane of foramen magnum. It is composed of an inner core of gray matter in which nerve cells predominate, and an outer layer of white matter in which myelinated nerve fibers predominate, and surrounds the central canal. (CUMBO). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the spinal cord is

Part of the central nervous system located in the vertebral canal continuous with and caudal to the brain; demarcated from brain by plane of foramen magnum. It is composed of an inner core of gray matter in which nerve cells predominate, and an outer layer of white matter in which myelinated nerve fibers predominate, and surrounds the central canal. (CUMBO). The atlas records it as a organ at the organ scale in the human body.

Where the spinal cord is

It sits in the back, within the nervous system. Positioned deliberately as part of this species body plan.

What the spinal cord connects to

The atlas records 55 typed relationships for it, across 11 kinds of connection. part of central nervous system and dorsum.

Supply and innervation

Arterial supply: anterior spinal artery and vertebral artery. Venous drainage: vertebral vein.

Also called

Also recorded as SpC, cerebro-cerebellar fissure, cerebrocerebellar fissure, fissura cerebro-cerebellaris, fissura cerebrocerebellaris and medulla spinalis, and 2 more. Searching any of those names reaches this page.

Questions

Where is the spinal cord?

It sits in the back, within the nervous system. Positioned deliberately as part of this species body plan.

What does the spinal cord connect to?

Part of: central nervous system and dorsum.

Is the spinal cord the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
