Examples of receptors in the nervous system include:

cells in the retina of the eye

Outputs. (efferents) of the nervous system may result in:

contraction of the biceps femoris

Outputs of the nervous system may result in:

 

increased salivation

Outputs of the nervous system may include:

increased heart rate

Inputs to the nervous system may include:

 

position of joints

Which of the following is part of the peripheral nervous system?

 

ulnar nerve

In general, motor pathways are _________________ to the central nervous system.

efferent

A ______________ is a collection of nerve cell bodies in the peripheral nervous system.

ganglion

In general, sensory pathways are _________________ to the central nervous system.

afferent

The central nervous system includes:

brain and spinal cord

A ______________ is a collection of nerve cell bodies in the central nervous system.

nucleus

The neuronal cell type shown at "1" is

multipolar

The neuronal structure shown at "7" is the

axon

At a synapse, the postsynaptic cell contains:

receptors

In the cerebrum, gray matter is ______ to the white matter. 

superficial

The neuronal cell type shown at "2" is

unipolar

This glial cell type is found only in the central nervous system.

ependymal cells

This glial cell wraps axons in an insulating layer of myelin in the central nervous system. It periodically leaves gaps called nodes of Ranvier to allow for electrical activity in nerve cell axons.

oligodendrocyte

_________________ cells support regrowth of cut nerve axons. Oligodendrocytes do not.

Schwann cells

Cells in the nervous system that play a major role in support and nutrition of brain cells are:

glial cells

This glial cell type is found only in the central nervous system.

microglia

The ________________ ("horse's tail") are a loose bundle of nerve roots at the caudal end of the spinal cord. These roots float in the lumbar cistern, a pool of cerebrospinal fluid. The lumbar cistern is where clinicians remove CSF in a procedure called a lumbar puncture (spinal tap). 

cauda equina

What is the structure at "3"?

anterior (ventral) columns

Identify the structure indicated by the number 4.

anterior (ventral) horn

Which of these structures is formed by cell bodies of autonomic neurons in the thoracic region of the spinal cord?

5

Which spinal nerve plexus is indicated by the number 1?

cervical

A spinal nerve exits the vertebral canal through the:

intervertebral foramen

Which of the following is made up of the telencephalon and the diencephalon?

Prosencephalon

The structure indicated at "3" is the:

central sulcus

The structure indicated by "1" is the:

frontal lobe
