BIOL 1102 Chapter Notes - Chapter 17: Bulbourethral Gland, Anterior Pituitary, Prostaglandin
Document Summary
At puberty, the hypothalamus releases gnrh in pulses every 1-2 hours. This causes the anterior pituitary to increase the production of lh that causes the testes to release testosterone and fsh that causes testes to start sperm production: lh. Causes testes to release testosterone: fsh. Causes testes to make sperm and ovaries to make eggs: function of scrotum. Keep the testes at the best temperature for sperm production: best temperature for sperm production. In mammals, slightly below body temperature: bulbourethral gland. Male alkaline fluid to reduce acidity in urethra and vagina. Sometimes carries small amounts of sperm (pre-ejaculatory fluid: prostate gland. Makes alkaline fluid and activates sperm swimming. Makes 2 enzymes, one clumps sperm before ejaculation, another breaks it up after. Produce prostaglandins to move sperm toward egg: seminal vesicles. Hypothalamus releases gnrh that causes anterior pituitary to release luteinizing hormone (lh) and fsh. These hormones stimulate the ovaries to produce an egg follicle, which produces the hormone estrogen.
