Study Notes
The Male Reproductive System
- Located in the pelvis region
- Includes a pair of testes, accessory ducts, glands, and external genitalia
- Testes are divided into testicular lobules, each containing 1-3 seminiferous tubules
- Seminiferous tubules produce sperm and are lined with male germ cells (spermatogonia) and Sertoli cells
- Sertoli cells provide nutrition to germ cells
- Interstitial spaces outside seminiferous tubules contain small blood vessels, interstitial cells (Leydig cells), and immunologically competent cells
- Leydig cells synthesize and secrete testicular hormones (androgens)
Male Accessory Ducts and Glands
- Include rete testis, vasa efferentia, epididymis, vas deferens, seminal vesicle, and prostate gland
- Epididymis stores and transports sperm from testis to urethra
- Vas deferens ascends to abdomen, loops over urinary bladder, and receives duct from seminal vesicle
- Ejaculatory duct opens into urethra
- Urethra originates from urinary bladder, extends through penis, and opens at urethral meatus
Male External Genitalia
- Penis is made of special tissue that helps in erection
- Enlarged end of penis is called glans penis, covered by a loose skin called foreskin
- Accessory glands (seminal vesicles, prostate, and bulbourethral glands) produce seminal plasma rich in fructose, calcium, and enzymes
- Secretions of bulbourethral glands also help in lubrication of penis
The Female Reproductive System
- Consists of a pair of ovaries, oviducts, uterus, cervix, vagina, and external genitalia in the pelvic region
- Includes paired mammary glands
- Oviducts are accessory ducts from the periphery to the ovary infundibulum
Female Reproductive System Structure
- Uterus consists of endometrium, myometrium, and perimetrium
- Vaginal orifice is the external opening of the vagina
- Labia minora and labia majora are part of the female external genitalia
