,1. What is the system that promotes sexual arousal as part of the autonomic nervous
system?
Alzheimer's disease
Proprioceptor
✓ Parasympathetic nervous system
Computerized axial tomography (CAT)
Rationale: The parasympathetic nervous system is responsible for "rest and digest"
functions, including promoting sexual arousal. The sympathetic nervous system is more
involved in orgasm.
2. Which disorder of the spinal cord refers to a loss of voluntary movement in one part
of the body?
Atrophy
Ataxia
✓ Paralysis
Seizure
Rationale: Paralysis is the loss of voluntary muscle movement. Atrophy is wasting away
of tissue; ataxia is loss of coordination.
, 3. Which route describes the correct path of light through the eye?
Light passes from bipolar cells to amacrine cells, then to horizontal and ganglion cells,
and finally to the optic nerve.
✓ Light passes from receptors to bipolar and horizontal cells, then to amacrine
and ganglion cells, and then to the optic nerve.
Light passes from receptors to ganglion cells, then to horizontal and amacrine cells,
and then to the optic nerve.
Light passes from horizontal cells to amacrine cells, then to bipolar and ganglion cells,
and then to the optic nerve.
Rationale: Light hits photoreceptors (rods/cones) → bipolar & horizontal cells →
amacrine & ganglion cells → optic nerve.
4. What involves decreased inhibition of the globus pallidus by the striatum?
Parkinson's disease
Alzheimer's disease
Huntington's chorea
✓ Huntington's disease
Rationale: In Huntington's, the striatum degenerates, leading to less inhibition of the
globus pallidus, causing involuntary movements.
5. Which condition offers proof that good language abilities can be present in spite of
other impairments?
✓ Williams syndrome
Marfan syndrome
Edwards syndrome
Angelman syndrome
