Reproduction HW by Patricia Kelley



 (1) When is an individual capable of producing children? - An individual can produce children after they go through puberty.

(2) Where are sperm produced? - The sperm are produced within the testes.

(3) Where are eggs produced? - Eggs are produced within the ovaries.

(4) How many chromosomes does the mother contribute via the egg to the new individual? - The egg contains 23 of the mother's chromosomes.

(5) How many chromosomes does the father contributed via the sperm to the new individual? - The sperm contains 23 of the father;s chromosomes.

(6) What male structures are involved in the making of seminal fluid? - The testes, the epidymis, the seminal vesicles, the prostate gland and the bulbourethral glands are all involved in the making of seminal fluid.   (7) Describe the cells and structures involved in making mature sperm. - The sperm is produced by the testes within the epidiymis.The seminal vesicles, the prostate gland and the bulbourethral glands add secretions to the seminal fluid.

(8) Which hormones control the male reproductive cycle? Describe the function of each. - The GnRH stimulates the anterior pituitary to secrete the gonadotropic hormons. The gonadotropic hormones can stimulate hair growth (FSH) and controls the production of testosterone by the intersitial cells (LH). Testosterone creates greater muscle develo  pment, develops male reproductive organs and brings about secondary sec characteristics (beards, adams apple etc...)

(9) Describe the function of the ovaries, oviducts, uterus, cervix, and vagina. - The ovaries:produce eggs and female sex hormones - oviducts: the area where the egg is propelled into the ciliary movement - uterus: houses developing fetus - cervix: contains opening to uterus - vagina: receives penis during intercourse, birth canal and exit for menstrual flow

(10) Which hormones control the female reproductive cycle? Describe the function of each. - Estrogen: responsible for female secondary characteristics (body hair etc..) - Progesterone: partly responsible for breast development
