alexandr1967 [171]

High levels of cortisol would normally provide negative feedback to the D)the anterior pituitary and the hypothalamus.

ACTH secretion stimulates the discharge of glucocorticoids (cortisol), mineralocorticoids (aldosterone), and androgen from the adrenal cortex.

Corticotropin-liberating hormone (CRH) is launched from the hypothalamus, which stimulates the anterior pituitary to release adrenocorticotropic hormone (ACTH). ACTH then acts on its target organ, the adrenal cortex.

Cortisol increases blood sugar by way of releasing stored glucose, at the same time as insulin lowers blood sugar. Having chronically high cortisol stages can result in continual high blood sugar (hyperglycemia). this can purpose type 2 diabetes.

95% of the cells in the epidermis are keratinocytes

Basal cells are multipotent stem cells that are important in the regeneration of homeostasis of the respiratory epithelial cell population.

in skin growth, most of the cells are keratinocytes and they are formed by the division of stem cells in the basal layer
