-meninges -vertebral canal -cerebrospinal fluid
Select the cranial nerve responsible for vision.
II
Select the cranial nerves responsible for movement of the eyeball.
III, IV and VI
Which part of the brain consists of the medulla oblongata, pons, and midbrain?
brain stem
The part(s) of the brain that helps to coordinate complex skeletal muscle movements is(are) the
cerebellum
The sites of CSF production are
choroid plexuses
Cerebellum function to:
coordinate movements and regulate balance
The thalamus is found in the region of the brain known as the
diencephalon
Spinal nerves connect to the spinal cord by
dorsal and ventral roots
The layer of the meninges that is located closest to the surrounding bone is called the
dura mater
The auditory association area is located in the diencephalon.
false
The cerebrum regulates posture and balance.
false
Damage to the choroid plexus would interfere with
formation of cerebrospinal fluid
The main source of energy for the brain is
glucose
The gray matter of the spinal cord is divided into regions known as
horns
Which part of the brain controls body temperature, hunger, thirst and emotions such as rage?
hypothalamus
The hypothalamus is considered part of both the nervous system and the endocrine system because it
integrates activities of the ANS and controls release of hormones from the pituitary gland.
Which of the following areas of the brain is sometimes referred to as the "emotional brain"?
limbic system
All of the following areas of the brain are involved in storing or processing memories EXCEPT the
medulla oblongata
The cardiovascular center, which controls the rate and force of the heartbeat and the diameter of blood vessels, is located in the
medulla oblongata
The control center that adjust the basic rhythm of breathing is found in the
medulla oblongata
The portion of the brain stem that is continuous with the spinal cord is the
medulla oblongata
The vital centers for heart rate, respiratory rhythm, and blood vessel diameter are regulated by the
medulla oblongata
In a reflex arc, the nerve impulse is transmitted directly to the effector by the
motor neuron
The primary visual area of the cerebrum is located in the
occipital
The primary somatosensory area is located in the ______ and is responsible for ______.
parietal lobe; perception of touch, pain, and temperature
The innermost layer of the meninges is the
pia mater
Which of the following areas of the cerebral cortex receives nerve impulses for touch, proprioception, pain, itch, tickle, and temperature?
primary somatosensory area
The blood-brain barrier functions to
protect brain cells from many pathogens
In the knee jerk reflex shown in the figure, which of the following components of the reflex arc serves as the effector?
quadriceps femoris muscle
Which of the following best describes a characteristic of the pineal gland?
secretes a hormone that promotes sleepiness
Which type of neuron conducts nerve impulses toward the central nervous system?
sensory
The central nervous system (CNS) consists of the brain and
spinal cord
In a spinal tap, cerebrospinal fluid is removed from the
subarachnoid space
This space between the arachnoid mater and pia mater is called the
subarachnoid space
A shallow groove on the surface of the cerebrum is called a
sulcus
The primary auditory area of the cerebrum is located in the
temporal lobe
In a somatic reflex
the effector is skeletal muscle.
From early adulthood onward, the number of neurons in the brain does not decrease much but the number of synapses steadily declines.

true
There are twelve pairs of cranial nerves and 31 pairs of spinal nerves.
true
The _____ nerve is the longest cranial nerve.
vagus
The cranial nerve responsible for hearing is the
vestibulocochlear (VIII) nerve
The spinal cord consists of
white matter and gray matter
