GUARANTEED.
The eye muscles that control the size of the pupil and affect accommodation are:
extrinsic muscles.
suspensory ligaments.
ciliary body.
intrinsic muscles.— Answer: intrinsic muscles
Activation of the sympathetic nervous system (SNS):
is sometimes referred to as the "feed-and-breed" division of the SNS.
has a calming effect on the body.
can "brady down" an individual.
is sometimes referred to as the fight-or-flight division of the SNS.— Answer: is sometimes
referred to as the fight-or-flight division of the SNS.
Dopamine receptors (adrenergic receptors):
are part of the craniosacral outflow.
cause blood vessels in the kidney to dilate and blood flow in the kidneys to increase.
are located in the bladder.

,are vagolytic.— Answer: cause blood vessels in the kidney to dilate and blood flow in the
kidneys to increase.
Atropine, when administered for a dangerously slow heart rate, is considered:
sympathomimetic.
parasympatholytic.
parasympathomimetic.
sympatholytic.— Answer: parasympatholytic
The autonomic nervous system:
.is part of the peripheral nervous system
innervates only skeletal muscle.
is composed of only sensory fibers.
is restricted to regulations of head and neck.— Answer: is part of the peripheral nervous system
Paralysis of the upper and lower extremities is:
called quadriplegia.
most often temporary.
called hemiplegia.
usually caused by an infection.— Answer: called quadriplegia.

, central sulcus.
central canal.— Answer: central sulcus.
Basal nuclei:
are patches of white matter scattered throughout the cerebrum.
are located in the peripheral nervous system.
help regulate body movement and facial expression.
are regulated by the neurotransmitter serotonin.— Answer: help regulate body movement and
facial expression.
Which statement is incorrect regarding synapses and nerve impulses?
A nerve impulse of the presynaptic neuron causes the release of a neurotransmitter into the
synaptic cleft.
The neurotransmitter diffuses across the synaptic cleft and binds to the receptors on the
postsynaptic membrane.
Activation of postsynaptic receptors stimulates the synthesis of myelin sheath.
A synapse is the space between two neurons.— Answer: Activation of postsynaptic receptors
stimulates the synthesis of myelin sheath.
Astrocytes— Answer: Help form the blood-brain barrier
Ependymal cells— Answer: Help form cerebrospinal fluid
Microglia— Answer: Engage in phagocytosis
Schwann cells— Answer: Form myelin in the peripheral nervous system
Oligodendrocytes— Answer: Make myelin in the central nervous system
