A casual glance reveals that the patient's finger bones are enlarged in diameter, a heavy deposition of bones exists over the eyes, and the patient has a prominent jaw. The doctor tells you that the headaches and visual disturbances results from increased pressure within the skull and that the patient is suffering from pituitary tumor that is affecting hormones secretion. NAME THE HORMONE THAT IS CAUSIGN THE PROBLEM, AND EXPLAIN WHY AN INCREASE IN PRESSURE EXISTS WITHIN THE SKULL.

2.) The hypothalamohypopyseal portal system connects the hypothalamus with the anterior pituitary. WHY IS SUCH A SPECIAL CIRCULATORY SYSTEM ADVANTAGEOUS?

I understand that oxytocin and vasopressin play a role in attachment, but what is the difference between the two. I know oxytocin plays a major role in female bonding with infants, but does it play a role in attachment with their partner too, what about vasopressin for females. what does oxytocin and vasopressin do for males?

Epinephrine and norepinephrine released from the adrenal glands affect target tissue for a longer period of time than the same substances when released from neurons at their peripheral receptors. Why?


A) The adrenal gland releases larger amounts of the neurotransmitters than the neurons.

B) The hormones releases from the adrenal glands bind to different receptors than those released from other neurons.

C) There are no enzymes to break down epinephrine and norepinephrine in the blood and few enzymes in periperal tissues.

D) The effectors are less sensitive to epinephrine and norepinephrine that are released by the adrenal glands.

E) The epinephrine and norepinephrine from the adrenal glands are released by sympathetis neurons, whereas parasympathetic neurons release these substances at the effector organs.
