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
