This current page provides background support information for Medicine phase 1 BGD Histology Practical Virtual Slides. Page does not form part of the BGDA practical class virtual slides.

Objectives

Gain an overview of the microanatomy of the male reproductive system.
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 Histology

Epididymis Histology

Pseudostratified Epithelium

Nuclei of the epithelial cells are typically located in the widest part of the cell.
- the nuclei of cells that do or do not reach the surface of the epithelium are often located at different heights within the epithelium, giving the epithelium a "stratified" appearance.
The epithelium though is not stratified, therefore named "pseudostratified".

Terms

cortex - (Latin = rind, or bark) outer layer of an organ.
hilum - or hilus (Latin,= a trifle; depression in a seed) a depression at vascular entrance/exit of a gland or organ.
medulla - (Latin, medulla = pith, marrow) the inner portion of an organ, in contrast to cortex.
mucosa - (Latin, = mucous membrane) thin layer which lines body cavities and passages formed by epithelium and lamina propria.
parenchyma - (Greek," + enkeim = to pour in) the essential functional cells of an organ as opposed to its stroma.
serosa - (Latin, serum = whey; a pale fluid) a serous membrane lining body cavities.
stroma - (Greek, = a cover, table-cloth, bedding) term for the internal supporting frame-work of a tissue, or organ, as opposed to its parenchyma.
tunica albuginea - a dense, white, fibrous sheath enclosing a part or organ.
