What are the components of the male duct system?
Epididymis, prostatic urethra, vas deferens, ejaculatory duct, spongy urethra, membranous urethra
What are the accessory glands of the male reproductive system?
prostate, bulbourethral gland, seminal vesicle
What is the tunica albuginea and describe its location.
It is a white fibrous connective tissue coat on the surface of the testis
The tunica albuginea extends into the testis to form walls or septa, creating a number of small cavities called lobules. What structures, responsible for the production of sperm are found within each lobule?
Seminiferous tubules
Name the endocrine cells which are also located in these lobules and what hormone do they secrete?
Interstitial cells (leydig)- testosterone
Is testosterone amino acid, protein or steroid based?
Steroid
What is its mode of action?
Attach to carrier protein in blood, diffuses through cell membrane to directly influence DNA
Name the sequence of structures the spermatozoa pass through from seminiferous tubules to vas deferens
1) Seminiferous tubules 2) Straight tubules (rectus) 3) Rete tesits 4) Efferent ductules 5) Head of epididymis 6) body of epididymis 7) talk of epididymis 8) vas deferens
What type of epithelium lines the inside of the epididymis?
Pseudostratified columnar with elongated microvilli, known as stereocilia
What are stereocilia located here?
To increase the surface area of epithelium in order to absorb fluid, not movement
What is the function of the epididymis?
Also storage of sperm, phagocytosis of degenerating sperm, final maturation of sperm
How are sperm moved through the epididymis?
Muscular contractions of its smooth muscle wall
The vas deferens is a tube that transports sperm from the epididymis to the ejaculatory duct, located posterior to the bladder. The vas deferens travels inside the spermatic cord on its way to the pelvic cavity. What other structures are found in the spermatic cord?
Testicular artery, nerves, lymphatics and pampiniform plexus
