What are the two types of adrenal receptors?
|
1) Mineralcorticoids2) Glucocorticoids
|
|
| 7 |
What are the differences between mineral corticoids and glucocorticoids?

Affinity for steroids (mineral = high; gluco = low)Hormone release (mineral = stimulate; gluco...
|
|
| 8 |
Which areas of the brain will be stimulated at all times (*hint: because of adrenal receptors)?
|
Hippocampus and amygdala (since mineral corticoid receptors which have high affinity are located...

Where are thyroid receptors located?
|
Cerebellum, limbic system, and the brain stem

|
| 10 |
Which receptors do thyroid receptors have a close relationship with?

Thyroid
|
|
| 13 |
What brain area is highly sensitive to fluctuations in gonadal and adrenal hormones?
|
Hippocampus
|
|
| 14 |
At which time are dendritic spines in the hippocampus are at their highest density?
