Multiple Choice

Is the hypothalamus a part of the endocrine system?

• Yes

• No

Multiple Choice

Hormones that travel through the bloodstream without a transport protein are called:

• peptide hormones

• steroid hormones

Multiple Choice

What is a tropic hormone?

• A hormone that promotes the growth and nourishment of tissues

• A hormone that directly influences non-endocrine target tissues

• A hormone that stimulates other endocrine glands to release hormones.

• A hormone that regulates metabolic activities in cells.

Multiple Choice

What is the sensor in a nervous system information flow?

• the body structure that wil do something in response to a stimulus

• what the target does

• the receptor/ the cell structure that detects the change

• a change in the environment

Multiple Choice

Antidiuretic hormone (ADH) is released by the Posterior Pituitary gland and travels through the bloodstream to act on the kidneys, where it regulates water balance and other things. Which type of hormone signaling does this represent?

• paracrine

• autocrine

• circulating

Multiple Choice

Cortisol, a hormone that easily passes through cell membranes, binds to intracellular receptors, and directly influences gene expression, belongs to which category of hormones?

• peptide hormone (water-soluble)

• biogenic amine (water-soluble)

• steroid hormones (lipid-soluble)

• thyroid hormones (lipid-soluble)

Multiple Choice

Both the Nervous System and the Endocrine system use chemical messengers to communicate.

• True

• False

Multiple Choice

This T cell is a helper cell, what kind of hormone is this process demonstrating?

• circulating hormone

• paracrine hormone

• autocrine hormone

Multiple Choice

Insulin is released by the Pancreas in response to elevated blood glucose levels. As insulin lowers blood glucose levels, it reduces the stimulus for further insulin release. This regulatory mechanism is an example of:

• Positive Feedback

• Negative Feedback

Multiple Choice

A hormone that can travel through the blood without a transport protein is a:

• steroid hormone

• peptide hormone

Multiple Choice

Which of these is not a function of the endocrine system?

• Reproduction

• Regulating metabolism and energy balance

• Controlling voluntary muscle movements

• Supporting growth, developmen
