Q

Of the two sensory processing pathways from thalamus to the amygdala, which is the faster pathway? Which is the higher order pathway and why?

Q

Outline the steps of the HPA axis.

A

1) para ventricular nucleus of the hypothalamus releases corticotropin releasing hormone (CRH) in response to a stressor
2) CRH acts on the anterior pituitary gland and stimulates the release of adrenocorticotropic hormone
3) ACTH acts on the adrenal cortex stimulating the release of glucocorticoid hormones (specifically cortisol) into the blood stream
4) The release of cortisol initiates a negative feedback loop, acting back on the hypothalamus and anterior pituitary to suppress the release of CRH and ACTH

Q

What does stress do to levels of Gonadotropin releasing hormone? What does this in turn do?

A

Decreases levels of GnRH and subsequently levels of LH and FSH in the body; this results in lower levels of estrogen and progesterone, as well as irregular menstrual cycles; eggs are not released and it is more difficult to become pregnant
