Talk:BGDA Practical - Male Reproductive Tract Histology

From Embryology

Practical 10: Histology of the Male Reproductive Tract

Principal Teacher: Dr Patrick de Permentier

Objectives

  1. Gain an overview of the microanatomy of the male reproductive system.
  2. Undertake a microscopical examination of the testis, epididymis, vas deferens, seminal vesicle, prostate 
gland, penis, and sperm. The functional significance of the various histological structures identified will be discussed.

Testis and Rete testis

  • Identify the tunica albuginea. What type of tissue resides here?
  • Identify the mediastinum testis and the rete testis.
  • What is the function of the rete testis?
  • Identify a seminiferous tubule and locate within it; spermatogonia, spermatocytes, spermatids, and Sertoli cells. Name a function of a Sertoli cell?
  • Locate blood vessels in the connective tissue septa.
  • Identify the interstitial cells of Leydig and give their function.


Efferent ductules and Epididymis

  • Identify the efferent ductules and epididymis.
  • What type of epithelium lines the efferent ductules and epididymis and what surface specialisation is present?


• Name one function of the epididymis.

Vas deferens

  • Identify the epithelium and muscle layers.
  • What structures reside in the lamina propria (proper layer)?
  • What structures reside in the adventitia (outer layer)?
  • What is the function of the vas deferens?

Seminal vesicle

  • Identify the epithelium and muscle.
  • What is the function of the paired seminal vesicles? 


Prostate glands (adult)

Also an infant prostate gland and a prepubescent prostate gland.

  • Identify the prostatic urethra, prostatic glands, prostatic concretions and stroma.
  • What type of epithelium lines the prostatic urethra?
  • Name 2 products produced by the prostate gland and what are their functions?
  • Observe the increase in prostatic glands with age.
  • Notice that the prostate gland is encapsulated and what is the clinical significance of this in prostatic carcinoma? 


Penis

  • Identify the urethra, corpus spongiosum, corpus cavernosum, mucous glands of Littre, blood vessels and 
nerves.
  • What type of epithelium lines the penile urethra?
  • Identify the cavernous sinuses and tunica albuginea.

Sperm

• Identify the head, midpiece and tail of an individual sperm and present individual functions of these structures.
