Estrogen has many roles, what are two target cells used during the female’s monthly cycles.
• Follicles of the ovaries (ovarian cycle) • Uterus (menstrual cycle).
Name some of the cells targeted by estrogen in producing some of the female’s secondary sex characteristics?
• underarm hair follicles produce hair • pubic hair follicles • development of breast tissue
Name the two major target cells for progesterone.
The uterine inner layer called the endothelium. The lactating (nursing) breast cells during pregnancy.
Testosterone plays a role in sperm development. The target cells where sperm are made are the ___________________ in the testes.
Seminiferous tubules
Testosterone also is important for the male’s secondary sex characteristics. Name some of the target cells that testosterone will attach to.
• underarm hair follicles to produce hair • pubic hair follicles • voice box in the larynx to deepen voice • skeletal muscles
The target cells of follicle stimulating hormone for females are:
The follicles of the ovaries that are developing with eggs.
The target cells of follicle stimulating hormone for males are:
the seminiferous tubules where sperm are produced in the testes.
The target cells of luteinizing hormone for females is the ovarian follicle that releases the egg during ____________________.
ovulation.
The target cells of luteinizing hormone for males are the __________________ of the testes that make testosterone.
the interstitial cells (cells of Leydig)
The two group of target cells of oxytocin for females are
• The smooth muscle of the uterus during labor • The breast cells important in lactation (for nursing).
