Question 1

The central nervous system consists of which of the following?

The brain and spinal cord
Nerves and ganglia outside the brain and spinal cord
Sensory receptors and effector organs only
The meninges and cerebrospinal fluid only

Question 2

Afferent nerve fibers in the peripheral nervous system carry nerve impulses:

From sensory receptors or sense organs toward the central nervous system
From the central nervous system to muscles and glands
Between the left and right cerebral hemispheres
From the spinal cord to the brainstem

Question 3

Which statement best describes motor neurons?

They have cell bodies in the spinal cord and axons that project outside the spinal cord to control effectors
They carry sensory impulses from receptors to the CNS
They connect the two cerebral hemispheres
They produce cerebrospinal fluid in the ventricles

Question 4

The dura mater is the outermost of the three meningeal layers.

True
False

Question 5

Cerebrospinal fluid is produced in which location?

In the choroid plexuses of the brain's ventricles
In the subarachnoid space
In the cerebral cortex
In the peripheral ganglia

Question 6

The telencephalon is the embryonic structure that gives rise to the:

Cerebral cortex and basal ganglia
Thalamus and hypothalamus
Cerebellum and pons
Meninges and cerebrospinal fluid

Question 7

The ______ is the cerebrum's outer layer of neural tissue.

Fill in the blank

Question 12

What is aphasia?

A collection of language disorders caused by brain damage in a person with previously normal language skills
A motor disorder caused by spinal cord damage
Inflammation of the meninges
Loss of cerebrospinal fluid from the ventricles

Which lobe lies below the lateral sulcus and is involved in hearing, language comprehension, and emotional association?

Temporal lobe
Frontal lobe
Parietal lobe
Occipital lobe
