Reproduction hormones-secreting organ, target, fx
*Hormone chart*
Divisions of pituitary glands, hormones secreted by each
Anterior Pituitary (adrenohypophysis)
GH-Growth Hormone
Prolactin
ACTH-Adrenocorticotropic hormone
FSH-Follicle-stimulating hormone
LH-Luteinzing hormone
Posterior Pituitary (neurohypophysis)
ADH-Antidiuretic hormone
Oxytocin
Structures of Male & Female Reproductive Organs
Males:
Vas Deferens
Urethra
Penis
Glans Penis
Prepuce (foreskin)
Seminal Vesicle
Ejaculatory duct
Prostate Gland
Bulbourethral Gland
Epididymis
Testis
Scrotum
Female:
Ovary
Uterus
Endometrium
Myometrium
Perimetrium (epimetrium)
Cervix
Vagina
Fallopian Tube
Production of Sperm
1. Testes
2. Epididymis
3. Vas deferens
4. Seminal Vesicle
5. Prostate gland
6. Bulbourethral gland
7. Urethra
8. Penis
9. Chromosome, #, gender determination
10. Zygote: 46 chromosomes (23 from egg, 23 from sperm)
11. Gender is determined at conception by the sperm (x&y)
12. Congenital vs. Hereditary Disease
Congenital Disease: conditions are present at the time of birth Hereditary Disease: genetically transmitted
13. Mechanism of the Birth Control Pill
14. Is a pharmacological agent that contains estrogen & progesterone. As the blood levels of estrogen & progesterone increase, negative feedback inhibits the secretion of FSH by the anterior pituitary. This process prevents ovulation, no egg means no baby. 15. Endocrine Glands & Hormones secreted by each

16. Each gland are ductless glands, they secrete hormones directly into the blood and not into ducts Pituitary Glands-GH, Prolactin, ACTH, FSH, LH, TSH, ADH, oxytocin Hypothalamus-releases a releasing hormone

Pineal Gland-melatonin
Thyroid –calcitonin, Thyroxin (T4), Triiodothreonine (T5)
Parathyroid-parathyroid hormone
Thymus-thymosin
Adrenals-epinephrine, norepinephrine, aldosterone, cortisol
Ovaries-estrogen & progesterone
Pancreas-insulin & glucagon
Testes-Testosterone
17. Fertilization-gestation steps
18. The fertilized egg is called a zygote, zygote is the first cell of a new individual. The zygote begins to divide, forming a cluster of cells, that slowly makes its way thru the fallopian tube towards uterus. 19. Hyper & Hypoglycemia, symptoms

Hyperglycemia:
Excessive thirst
Fruity odor in breath
Excretion of large volume of urine
Excessive eating
Hypoglycemia:
Fainting
Weakness

27. Uterine Cycle
Menstrual Phase:
Loss of a part of the endometrial lining & blood
The Proliferative Phase:
The inner lining thickens & becomes vascular, primarily in response to estrogen The Secretory Phase:
The endometrial lining is becoming lush & moist from increased secretory activity, the secretory phase is dominated by progesterone 28. Ovarian Cycle:
29. 2 phases: follicular phase & luteal phase
The luteal phase of the ovarian cycle begins immediately after ovulation & is dominated by the secretion of progesterone by the corpus luteum In the nonpregnant state the corpus luteum deteriorates

In the pregnant state the corpus luteum stays alive because of human chorionic gonadotropin (hCG) During follicle phase the ovarian follicle mature & secretes estrogen 30. Cushing’s syndrome
31. Hyperactive adrenal; adrenocorticord
Moon face
Buffalo
Facial hair
Easily bruises
32. Grave’s Disease
33. Hyperthyroidism; characterized by an increase in heart rate, increase in peristalsis resulting in diarrhea, elevation in body temperature, hyperactivity, weight loss & wide emotional mood swings 34. Insulin & Glucophage Fx

Insulin:
Secreted by beta cells of the islets of Langerhans; helps regulate the metabolism of carbohydrates, proteins, & fats; lowers blood glucose levels Glucophage:
Secreted by the alpha cells of the islets of Langerhans; raises blood glucose levels 35. Vernix & Lanugo
Vernix Caseosa:
The skin is covered by a white, cheese-like substance. Thought to protect the delicate fetal...
