What anatomical and functional changes in the brain are linked to alterations that occur with aging?

The pons contains:

(a) Sensory and motor nuclei for six cranial nerves

(b) Nuclei concerned with the control of blood pressure

(c) Tracts that link the cerebellum with the brainstem

(d) No ascending or descending tracts

(e) Both a and b.

The 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

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?
