Spinal Cord & Brain Anatomy

The spinal cord consists of five regions and ________ segments

• 31

• Varies

• 5

• 12

The specialized membranes that surround the spinal cord are termed the

• spinal meninges.

• cranial meninges.

• cranial mater

• epidural membranes

The outward projections from the central gray matter of the spinal cord are called

• horns

• tracts

• fibers

• pyramids

The dorsal root of a spinal nerve contains

• interneurons.

• axons of sensory neurons.

• axons of motor neurons

• cell bodies of sensory neurons

The ventral root of a spinal nerve contains

• interneurons.

• axons of motor neurons.

• cell bodies of motor neurons

• axons of sensory neurons

The tough, fibrous, outermost covering of the spinal cord is the

• epidural block

• dura mater.

• arachnoid

• periosteum

The subdural space lies between

• the dura mater and the arachnoid mater.

• the arachnoid mater and the pia mater

• the pia mater and the dura mater

• the pia mater and the subarachnoid space

The gray horns of the spinal cord contain mainly

• funiculi.

• nerve cell bodies.

• meninges

• nerve tracts

The posterior horns of the spinal cord contain mainly

• somatic motor nuclei

• sensory nuclei.

• nerve tracts

• autonomic motor nuclei

The anterior horns of the spinal cord contain mainly

• sensory nuclei

• nerve tracts

• somatic motor nuclei

• autonomic motor nuclei
