Spinal Cord And Spinal Nerves

Front 1

White matter of spinal cord

Back 1

This area surrounds the gray matter. It is composed of both myelinated and un myeleinated axons. It has three regions, anterior, lateral, and posterior columns.

Front 2

Gray matter of spinal cord

Back 2

This area is shaped like a butterfly or the capital letter "H" in cross-section. It is composed of neuron cell bodies, neuroglia cells, dendriteds, and unmyelinated axons. It has three regions: the anterior, lateral, and posterior horns. The central canal is in the center of the gray matter.

Front 3

Dorsal root of spinal nerve

Back 3

These structures contain the axons of the autonomic sensory neurons.

Front 4

Dorsal root ganglion

Back 4

This area contains the cell bodies of somatic and autonomic sensory neurons.

Front 5

Ventral root of spinal nerve

Back 5

This structure contains the cell bodies of the somatic motor neurons that innervate the skeletal muscles.

Front 6

Spinal nerve

Back 6

These are the nerve tracks that connect the spinal cord with various regions of the body.
