Question

1. The ________________ releases epinephrine into the blood stream in response to neural stimulation by the sympathetic division of the ANS.

adrenal medulla

anterior pituitary gland

liver

adrenal cortex

hypothalamus

2. Transection (cutting) of the hypothalamo-hypophyseal tract, but NOT the hypophyseal portal venules, would prevent the secretion of which of the following?

anterior and posterior pituitary hormones

posterior pituitary hormones

anterior pituitary hormones

releasing and inhibiting hormones

3. Match each of the following descriptions to the type of hormone it is associated with.

Travel in the blood attached to a transport protein

Exert their effects on target cells by binding to receptors in the plasma membrane

Trigger the formation of second messengers, such as cAMP

Don't enter cells in the liver or pass through the kidney filtering mechanism easily when bound, so remain circulating in the blood longer

Include steroids

Alter target cell activity by turning specific genes on/off, which leads to a change in protein synthesis

Consist primarily of proteins or amino acid derivatives

Lipid-soluble hormones

Water-soluble hormones

a.

adrenal medulla

b.

anterior pituitary gland

c.

liver

d.

adrenal cortex

e.

hypothalamus

Explanation / Answer

Answer:

1)The Adrenal medulla releases epinephrine into the blood stream in response to neural stimulation by the sympathetic division of the ANS.

3)Lipid soluble harmone- travels in a blood attached to transport protein

Lipid soluble harmone- Exert their effects on target cells by binding to receptors in the plasma membrane

Water soluble harmone- Trigger the formation of second messengers, such as cAMP

Water soluble harmone-Don't enter cells in the liver or pass through the kidney filtering mechanism easily when bound, so remain circulating in the blood longer

Lipid soluble harmone-Include steroids

Water soluble harmone-Alter target cell activity by turning specific genes on/off, which leads to a change in protein synthesis

Lipid soluble harmone-Consist primarily of proteins or amino acid derivatives
