66 Hormones Homeostasis amp Reproduction
modified from Stephen Taylor i-Biologynet
The Endocrine SystemA stimulus is received and processed Hormones are secreted directly into the blood They are carried to the target tissues (the place of intended action) The action of the hormone changes the condition of the tissue This change in monitored through feedback Most hormonal change results in negative feedback
Key endocrine glands 1 Pineal gland2 Pituitary gland3 Thyroid gland4 Thymus5 Adrenal gland6 Pancreas7 Ovary (female)8 Testes (male)

Male Reproductive System66 S1 Annotate diagrams of the male and female reproductive system to show names of structures and their functions
Male Reproductive System
1 Epididymusbull Large coiled tube (23 ft long) that surrounds testesbull Stores sperm (about 20 days)bull During ejaculation about 400 million sperm cells are propelled from epididymis
66 S1 Annotate diagrams of the male and female reproductive system to show names of structures and their functions
2 Vas Deferensbull Long muscular ducts from scrotum to
back of bladderbull During ejaculation the sperm pass
from epididymis into these two ductsVasectomy Each vas deferens is cut to
prevent sperm from entering urethra
3 Ejaculatory (Sperm) Ductbull Short duct after two vas deferens
ducts unite
4 Urethrabull Deliver sperm to the exteriorbull In males urine and sperm pass
through the urethra
5 Scrotumbull maintains temperature (lower than body)
that sperm require for normal development
66 U1 A gene on the Y chromosome causes embryonic gonads to develop as testes and secrete testosterone
bull Initially the development of the embryo is the same in all embryos and embryonic gonads could develop into testis of ovaries
bull The developmental pathway for the gonads depends on presence or absence of one gene
bull When SRY is present the gonads develop into testes
bull SRY codes for a DNA binding protein called TDF (testis determining factor)
bull TDF stimulates the expression of other genes that cause the development of the testis
66 U3 Estrogen and progesterone cause pre-natal development of female reproductive organs and female secondary sexual characteristics during puberty
Side View of Female Reproductive System
Major Organs of Female Reproductive System
1 Ovaries Produce ova (egg) and sex hormonesraquoSize and shape of large almond
Follicles A single egg with surrounding cells that nourish and protect it Women are born with all of their follicles (40000 to 400000)
66 S1 Annotate diagrams of the male and female reproductive system to show names of structures and their functions
Major Organs of Female Reproductive System
2 Oviducts (Fallopian Tubes) Transport the egg from the ovary to the uterus Fertilization occurs here
3 Uterusbull Has thick walls of smooth muscle responsible for uterine
contractions and crampsbull Inner mucous lining which thickens each month in
preparation for pregnancy If fertilization does not occur breaks down and is discharged during menstruation
bull If fertilization occurs the egg implants and helps support growth until the placenta develops
4 Cervix Lower portion of the uterus which projects into the vagina
5 Vagina Thin walled muscular chamberbull Receives the sperm and penisbull Acid pH kills bacteria and sperm cellsbull Part of birth canal
Feedback Regulation of Oogenesisbull feedback regulation of female
reproductive cycle is negative and positive
bull leads to female cyclesbull hypothalamus and pituitary
control ovariesbull ovarian hormones control
uterus
66 U4 The menstrual cycle is controlled by negative and positive feedback mechanisms involving ovarian and pituitary hormones
Ethical Issues with in vitro fertilization
Advantages of IVF there are as many reasons for this treatment as there are people seeking this treatment As examples
bullOver comes infertilitybullAllow families for people who must be sterilized eg
radiographychemo therapy cancer patients
Disadvantages of IVFbullWhat happens to unwanted embryosbullWhat happens to orphaned embryosbullShould infertility be by-passed
66 A2 William Harveyrsquos investigation of sexual reproduction in deer
bull Embryogenesis an early theory of egg development proposed by Aristotle His idea called the Seed and soil theory believed that males produce seed females form an egg which mixes with menstrual blood to develop into a fetus inside the mother
bull William Harvey tested this idea by shooting deer during mating season
bull He discovered that it took months for the fertilized egg to develop in the uterus
bull This help debunk the idea of Spontaneous generation and lead to a better understanding of embryology
