Study Notes
Learning Outcomes
- State the functions and histological features of ovaries, uterine tubes, and the uterus.
- Differentiate between the layers of the uterine wall and specify changes during the uterine cycle.
- Recall the structures sperm passes through from formation to ejaculation.
- Recall cells/structures that produce testosterone.
Ovaries
-
Functions:
- Oocyte production for fertilization.
- Hormone secretion (estrogen and progesterone).
-
Histological Features:
- Follicles containing oocytes at various stages.
- Interstitial cells secreting hormones (estrogen and progesterone).
-
Support Structures:
- Ovarian ligament anchors the ovary to the uterus.
- Suspensory ligament connects the ovary to the pelvic wall.
- Mesovarium supports the ovary within the broad ligament.
Uterine Tubes (Fallopian Tubes)
-
Functions:
- Oocyte transport from the ovary to the uterus.
- Fertilization site (typically where fertilization occurs).
-
Histological Features:
- Mucosal layer with ciliated cells for oocyte movement and non-ciliated cells for nourishment.
- Muscularis layer for peristalsis.
Uterus
-
Functions:
- Protection and nutrition for the developing embryo/fetus.
- Waste removal.
-
Histological Features:
- Endometrium (innermost layer): Site of implantation and cycle changes.
- Myometrium (muscular layer): Contracts during labor.
- Perimetrium (outer serous layer).
-
Regions:
- Fundus (upper portion above fallopian tubes).
- Body (main portion where embryo implants).
- Isthmus (narrow portion connecting body and cervix).
- Cervix (lower portion connecting to vagina), including the isthmus portion.
- Supporting structures include broad ligament, which is involved in anchoring the uterus, uterine tubes, and ovaries. Supporting structures also include the pelvic floor muscles.
Structures Passed by Sperm (Formation to Ejaculation)
- Testes: Location in scrotum, sperm production in seminiferous tubules.
- Epididymis: Sperm maturation and storage.
- Vas Deferens (Ductus Deferens): Transports sperm to ejaculatory ducts.
- Ejaculatory Ducts: Formed by union of vas deferens and seminal vesicle ducts.
- Prostate Gland: Adds fluid to semen for nourishment and protection from acidity.
- Urethra: Carries semen to external opening.
Cells Producing Testosterone
- Leydig cells (Interstitial cells): Located between seminiferous tubules in the testes, produce and secrete testosterone in response to luteinizing hormone (LH).
Urinary System
- Organs: Kidneys, ureters, bladder, urethra.
- Kidney Structures: Renal artery and vein, nephrons (including glomerulus, glomerular capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, collecting duct,), renal pelvis, capsule.
- Nephrons: Responsible for urine formation (filtration, reabsorption, and secretion). Filtrate is formed and passes through the convoluted tubules for further processing, which involves reabsorption and secretion.
- Urine Transport: From ureters to bladder for storage, then to the urethra for elimination. The pathway includes the renal pelvis, minor calyces, major calyces, then to the ureter.
- Kidney Protection: Surrounding structures and fat pads provide protection. These include the fibrous capsule (connective tissue); paranephric fat and renal fascia.
Endocrine System
- Hormones: Chemical messengers produced by endocrine glands.
- Hormone function: Regulate metabolism, growth, reproduction, internal stability, and other body functions.
- Hormone Classification: Amines, polypeptides, proteins, glycoproteins, steroids (e.g., cortisol, TSH, ADH, insulin).
- Hormone Action: Hormone binds to specific receptors (on or within target cells to cause effects.)
- Endocrine Glands: Hypothalamus, anterior pituitary, posterior pituitary, thyroid, parathyroid. adrenal cortex and medulla, pancreas, testes, ovaries, and other glands.
- Hormone Regulation: Negative feedback loops (e.g., regulate hormone levels).
