13.2 True/False Questions
1) The hypothalamus, in addition to the cerebral cortex, is in control of emotional responses.
2) The pituitary gland (hypophysis) is connected to the hypothalamus and receives regulatory impulses that control the secretion of hormones.
3) The ventral portion of the cerebral peduncles connect the midbrain to the cerebellum and contain the pyramidal (corticospinal) motor tracts descending to the spinal cord.
4) The vasomotor center of the medulla regulates blood pressure.
5) In the olivary nuclei in the medulla, mostly proprioceptive sensory impulses are relayed to the cerebellum.
6) The medullary respiratory center controls the rhythm and rate of breathing.
7) Spinal nerve pairs in the cervical region of the spinal cord are found inferior to the vertebral bodies of the same number.
8) The cerebellum has an outer cortex, internal white matter, and areas of gray matter buried deep in the white matter.
9) Cerebrospinal fluid passes through choroidal villi to enter the superior sagittal sinus.
10) The reticular activating system (RAS) contains structures that regulate and cause emotional responses.
11) The amygdala is part of the limbic system and has neurons that process the emotions and reactions to fear.
12) The limbic system has neural ties to the autonomic nervous system, the hypothalamus, and the reticular formation.
13) The meninges of the brain differ from those of the spinal cord in that the dura mater of the brain splits into two layers and that there is no epidural space.
14) Damage to the ventral root causes spastic paralysis, whereas damage to the descending tracts causes flaccid paralysis.
15) The white matter of the spinal cord contains ascending and descending pathways known as tracts.
