The outer layer of the adrenal gland is called the ________.

The adrenal cortex produces a steroid hormone called ________ that controls Na⁺ and K⁺ homeostasis and another steroid hormone called ________ that controls blood glucose levels.

The sex hormones that regulate the male and female reproductive organs are collectively called ________.

Match each hormone with its primary source. -pineal

Match each term with the appropriate description. -true endocrine gland of epithelial origin

When a catecholamine or peptide hormone binds to receptors on the surface of a cell,

The ________ of a hormone is an indicator of how long a hormone is active in the body.

The trophic hormones reach the pituitary through the ________.

Match each hormone with its primary source. -adrenal medulla

The hormones of the anterior pituitary are controlled by trophic hormones from the ________.

One hypothalamic hormone triggers a pituitary hormone to cause release of an adrenal hormone.Fill in the names of the hormones below.If a tumor in the adrenal cortex resulted in hypercortisolism,how would this affect the relative levels of hormone produced from each source? What type of reflex pathway is involved? Hormone Source Tumor effects ________________________ Hypothalamus increase decrease ________________________ Anterior pituitary increase decrease ________________________ Adrenal cortex increase decrease

The link between a first messenger and a second messenger in a cell that responds to peptide hormones is usually

What are two benefits of having a portal system that connects the hypothalamus with the anterior pituitary gland? Are there any other endocrine axes connected by a portal system?

The pituitary hormone that controls the release of glucocorticoids from the adrenal cortex is

What normally stops hormone action,and why is this important?

A signal molecule that is secreted into the external environment,instead of into the blood,is called a(n)________.
