Lab 3 Male Reproductive System

A. Histology of Male Reproductive System

1. Slide #11B (testis)

Find – seminiferous tubules --- interstitial endocrinocytes (cells of Leydig) --- spermatogonium (large and on the edge of the tubule) --- spermatocytes (primary and secondary) going through meiosis --- spermatid (small, dark staining and round) --- spermatozoa (bullet-shaped cells with tails) --- sustentacular (Sertoli) cells (large nucleus with prominent nucleolus).

2. Slide #12B (penis)

Find – Dorsal artery and vein --- two corpora cavernosa penis --- corpus spongiosum penis --- spongy (cavernous) urethra --- median septum --- tunica albuginea --- deep arteries inside the corpus cavernosum.

B. Models of Male Reproductive System

Find – urinary bladder --- rugae --- trigone --- detrusor muscle --- ureter and ureteral openings --- prostate gland --- seminal vesicle --- scrotum --- testis --- epididymis --- vas (ductus) deferens --- spermatic cord --- cremaster muscle --- ampulla of vas deferens --- ejaculatory duct --- prostatic urethra --- urogenital diaphragm --- membranous urethra --- penis --- glans penis --- corpus spongiosum --- spongy (penile) urethra --- corpora cavernosa --- median septum --- pubic symphysis --- rectum --- external anal sphincter --- anus --- vesicorectal pouch --- pampiniform plexus.

2. Stand-up model of male urinary and reproductive systems (posterior view, sagittal view)

Find – urinary bladder --- seminal vesicle --- prostate --- crus, bulb and glans of penis --- ductus deferens --- testis --- epididymis --- trigone --- median septum.
