Gonadotrophin Releasing Hormone (GnRH), Lutenizing hormone (LH), Follicle Stimulating Hormone (FSH)
Name the key hormones that are central to the control of mammalian reproduction.
Which hormone is the main hormone in regulating progesterone synthesis in the corpus luteum?
1. Stimulate grown and activity of mammary gland and endometrium.
2. Prepare uterus for spermatozoal transport by increasing contractile activity of the uterus (OPPOSITE OF PROGESTERONE)
3. Prepare endometrium for progestagen action (induce progesterone receptors)
4. Increase vascular permeability and tissue edema
5. Regulate secretion of gonadotrophins (negative and positive feedback).
6. Associated with sexual behavior in some species.
7. Stimulate secondary sex characters of females.
Name 3 functions of estrogen. There are 7 total.
1. Induce and maintain differentiation of male somatic tissues (Induce secondary sex characters of males (deep voice, body hair, penile growth) and body hair of females; Induce and maintain some secondary sex characters of males (accessory sex organs))
2. Promote protein anabolism/ metabolism and somatic growth
3. Support spermatogenesis.
4. Influence sexual and aggressive behavior.
5. Regulate secretion of gonadotrophins (testosterone).
Name all 5 functions of androgens.
1. Budding: an offspring grows out of the body of the parent. Ex: Hydra genus (brine shrimp)
2. Gemmules (internal buds): a parent releases a specialized mass of cells that can develop into an offspring. Ex: sponges
3. Fragmentation: the body of the parent breaks into distinct pieces, each with can produce and offspring. Ex: flatworms.
4. Regeneration: if a piece of a parent is detached, it can grow and develop into a completely new individual. Ex: echinoderms, such as starfish, sea urchin.
Name the different forms of asexual reproduction and describe the difference between the forms.
