BackThe centers in the pons that modify the activity of the respiratory rhythmicity centers in the medulla oblongata are the:
(a) Apneustic and pneumotaxic centers
(b) Inferior and superior peduncles
(c) Cardiac and vasomotor centers
(d) Gracile nucleus and cuneate nucleus
Damage to the vestibular nucleus would lead to
(a) Loss of sight
(b) Loss of hearing
(c) Inability to sense pain
(d) Difficulty in maintaining balance
(e) Inability to swallow
Coordination of learned movement patterns at the subconscious level is performed by
(a) The cerebellum
(b) The substantia nigra
(c) Association fibers
(d) The hypothalamus
Briefly summarize the overall function of the cerebellum.
A police officer has just stopped Bill on suspicion of driving while intoxicated. The officer asks Bill to walk the yellow line on the road and then to place the tip of his index finger on the tip of his nose. How would these activities indicate Bill's level of sobriety? Which part of the brain is being tested by these activities?
What are the two primary functional roles of the cerebellum?
What varied roles does the hypothalamus play in the body?
Stimulation of which part of the brain would produce sensations of hunger and thirst?
The establishment of emotional states is a function of the:
(a) Limbic system
(b) Tectum
(c) Mammillary bodies
(d) Thalamus
Damage to the hippocampus, a component of the limbic system, leads to
(a) A loss of emotion due to forgetfulness
(b) A loss of consciousness
(c) A loss of long-term memory
(d) An immediate loss of short-term memory
Which structure in the brain is your A&P instructor referring to when talking about a nucleus that resembles a sea horse and that is important in the storage and retrieval of long-term memories? In which functional system of the brain is it located?
What cellular mechanisms identified in animal studies are thought to be involved in memory formation and storage?
What physiological activities distinguish non-REM sleep from REM sleep?
What constitutes the blood brain barrier?
Cerebrospinal fluid is formed by
