What does the male reproductive system generate?
Male gametes (sperm).
What does the female reproductive system generate?
Female gametes (ova, or eggs), fertilization (conception), implantation (start of pregnancy), gestation (pregnancy), and parturition (birth).
Describe the roles of follicle-stimulating hormone (FSH):
Secreted by the anterior pituitary that stimulates development of eggs in ovaries and sperm in testes.
Describe the roles of luteinizing hormone (LH):
Secreted by the anterior pituitary that is responsible for triggering ovulation in ovaries and the production of testosterone by testes.
Describe the roles of the pituitary gland:
Controls growth and development.
Describe the role of testosterone:
Hormone that stimulates male secondary sexual characteristics.
Describe the role of estrogen:
Female sex hormone released by the ovaries. Plays a role in egg maturation.
Apocrine sweat glands:
Accessory of the dermis in physical association with hair follicles, producing a secretion with an odor (possibly a sex pheromone).
Eccrine sweat glands:
Accessory of the dermis that secretes sweat, used primarily for regulation of body temperature.
Where are melanocytes located?
The epidermis.
What does the dermis contain?
Collagen, blood vessels, glands, hair follicles, and nerve endings.
What does the penal gland secrete?
Melatonin.
What releases insulin?
The pancreas; it signals cells to uptake sugar.
What does antidiuretic hormone do?
A secretion from the pituitary gland that increases the amount of water able to be reabsorbed from a collecting duct.
The endocrine system is a set of organs that secretes hormones directly into the:
Circulatory system (chemical signals travel through the bloodstream).
What does the hypothalamus secrete?
Both releasing and inhibiting hormones.
