Spinal Cord Anatomy

A series of flashcards covering the anatomy of the spinal cord based on the lecture notes.

Epidural Space

The fatty area surrounding the spinal cord.

Dura Mater

The outermost layer of the meninges protecting the spinal cord.

Arachnoid Mater

The middle layer of the meninges, located between the dura mater and pia mater.

Pia Mater

The innermost layer of the meninges that directly surrounds the spinal cord.

Gray Matter

The inner part of the spinal cord that contains neuronal cell bodies.

White Matter

The outer part of the spinal cord composed of myelinated axons.

Posterior Horn

The section of gray matter in the spinal cord responsible for sensory processing.

Anterior Horn

The section of gray matter that contains motor neurons.

Central Canal

The hollow space in the middle of the spinal cord.

Posterior Root Ganglion

A cluster of sensory neuron cell bodies located along the posterior roots.

Spinal Nerve

The nerve that emerges from the spinal cord, consisting of sensory and motor roots.

Rami Communicantes

Small branches that connect the spinal nerves to the sympathetic chain.

Subarachnoid Space

The space between the arachnoid mater and pia mater filled with cerebrospinal fluid.

Anterior Fissure

A deep groove on the anterior side of the spinal cord.

Posterior Median Fissure

A deep groove on the posterior side of the spinal cord.
