100

Which hormone is produced by the adrenal cortex during times of stress?

Cortisol

100

Which hormone stimulates the synthesis of melanin?

Melanocyte stimulating hormone

200

Which disorder involves the anterior pituitary gland releasing too little antidiuretic hormone?

Diabetes insipidus

200

Which hormone stimulate milk production in the breasts?

Prolactin

200
Which hormones are responsible for increasing the fight or flight response?

Epinephrine and norepinephrine

200

What do beta cells secrete?

Insulin

300

What hormone does fatty tissue release? What does this hormone do?

Leptin

Signals the hypothalamus that you have had enough to eat

300

What two hormones stimulates the ovaries and follicles?

Luteinizing hormone

Follicle stimulating hormone

300

What is the problem with diabetes insipidus?

It is the result of too little antidiuretic hormone being secreted by the anterior pituitary gland.

Draw graphs for each type of hormone secretion: constant, acute, and cyclic.

Constant

Acute

Cyclic

On your diagram, label: Hypothalamus, pituitary gland, thyroid gland, adrenal glands, kidneys, pancreas, testes is males, ovaries in females, pancreas, thymus, parathyroid, pineal body


400

What's the difference between the purposes of antidiuretic hormone and aldosterone?

Antidiuretic hormone - increases the amount of water maintained by the kidneys

Aldosterone - stimulates the kidneys to retain sodium and water

400

What's the difference between serotonin and melatonin?

Serotonin is  produced by the pineal gland when stimulated by light

Melatonin affects day-night cycle and reproductive readiness

400

Explain how the anterior pituitary gland is controlled.

It is controlled hormonally.  There are no neurosecretory cells that run into the anterior pituitary.  So, the hormones from the hypothalamus dump directly into the veins of the anterior pituitary

500

Explain four differences between the nervous and endocrine systems.

Nervous system is really fast, nervous is not.

Endocrine system has a longer duration of influence.

Nervous only controls muscles and glands, while endocrine controls everything

Endocrine tissue can repair itself (nervous can't)

500

Explain the difference between amides and steroids.

Amides are derived from amino acids

Steroids are derived from cholesterol

500

What's the difference between glucagon and insulin?

Glucagon increases glucose blood levels, while insulin decreases it

500

Explain how the posterior pituitary gland is controlled.

It is controlled directly by the nervous system.  The hypothalamus secretes neurohormones from neurosecretory cells.  The axons of these cells run through the infundibulum into the pituitary gland.  This allows the neurosecretory cells to produce hormones.
