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

Which hormone stimulates the synthesis of melanin?
Melanocyte stimulating hormone

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

Which hormone stimulate milk production in the breasts?
Prolactin

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.

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

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

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)

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.
