Study Notes
Male Reproductive System
- Gonads: Testes, responsible for sperm and testosterone production.
- Accessory Organs: Seminal vesicles, prostate gland, and bulbourethral glands (Cowper's glands), which produce seminal fluid.
-
Testes Structure:
- Scrotum: Skin pouch regulating testicular temperature.
- Tunica Albuginea: Fibrous covering surrounding the testes.
- Seminiferous Tubules: Coiled structures where spermatogenesis (sperm production) occurs.
- Interstitial Cells (Leydig Cells): Located between seminiferous tubules, produce testosterone.
- Testosterone: Principal male sex hormone, regulating sperm production and sexual characteristics.
- Epididymis: Coiled tube where sperm mature and are stored.
-
Pathway of Mature Sperm:
- Ductus (Vas) Deferens: Carries sperm from epididymis to ejaculatory duct.
- Ejaculatory Duct: Formed by vas deferens and seminal vesicle duct; passes through prostate to urethra.
- Urethra: Duct for sperm and urine exit.
-
Semen (Seminal Fluid): Fluid containing sperm, produced by accessory glands.
- Seminal Vesicles: Produce fructose-rich portion of seminal fluid.
- Prostate Gland: Produces fluid nourishing and transporting sperm.
- Bulbourethral Gland: Produces pre-ejaculatory fluid for urethra lubrication.
-
Male External Genitalia:
- Scrotum: Houses the testes.
-
Penis:
- Corpus Spongiosum: Surrounds urethra, preventing collapse during erection.
- Corpora Cavernosa: Two erectile tissues filling with blood during erection.
- Glans: Sensitive tip of the penis.
- Prepuce (Foreskin): Skin covering the glans (removed in circumcision).
Female Reproductive System
- Gonads: Ovaries, producing ova (eggs) and hormones (estrogen and progesterone).
- Accessory Organs: Uterine (Fallopian) tubes, uterus, and vagina.
- Ovaries: Almond-shaped structures on either side of the uterus, producing eggs and hormones.
-
Ovary Functions:
- Gametes: Produce ova.
- Hormones: Primarily estrogen and progesterone.
-
Female Reproductive Ducts:
- Fimbriae: Finger-like projections guiding the egg from ovary.
- Uterine (Fallopian) Tubes: Transport ova to uterus; site of fertilization.
-
Uterus:
- Fundus: Upper rounded portion.
- Body: Main part of the uterus.
- Cervix: Lower, narrow part opening to vagina.
- Myometrium: Muscular layer of the uterus.
- Endometrium: Inner lining, thickening for pregnancy.
- Vagina: Canal connecting external genitals to uterus.
-
Accessory Glands:
- Greater Vestibular (Bartholin’s) Glands: Provide vaginal opening lubrication.
-
Breasts:
- Lactiferous Ducts: Carry milk from lobules to nipple.
- Areola: Pigmented area surrounding the nipple.
-
External Genitalia (Vulva):
- Mons Pubis: Fatty tissue over the pubic bone.
- Clitoris: Erectile structure with nerve endings for arousal.
- Orifice of Urethra: Urine opening.
- Labia Minora: Inner folds protecting vaginal and urethral openings.
- Orifice of Vagina: Opening to the vagina.
- Labia Majora: Outer folds enclosing and protecting external structures.
