Liver and Reproductive System Histology Quiz

Liver Histology and Reproductive System Histology

Liver Histology:

• The liver is the largest internal organ in the human body, weighing about 1.5kg.
• It develops embryologically from the foregut and is anatomically divided into four lobes.
• The liver performs numerous functions, including the production and secretion of bile, conversion of excess glucose into glycogen, detoxification of drugs and poisonous substances, and synthesis of plasma proteins.
• Histologically, the liver consists of parenchyma, stroma, sinusoids, and spaces of Disse.
• The liver can be described as a classic lobule, portal lobule, or liver acinus.
• The classic lobule consists of hexagonal plates of hepatocytes stacked on top of each other with hepatic sinusoids traveling between the strips of hepatocytes.
• The portal lobule describes the exocrine function of the liver and is a triangle with a central axis through a portal canal.
• The liver acinus provides a more accurate description of the physiology of the liver and is in the shape of an oval.
• The liver can be affected by over a hundred different diseases, including hepatitis, cirrhosis, and liver cancer.

Reproductive System Histology:

• The male reproductive system is responsible for producing spermatozoa and introducing them into the female genital tract.

• The testes are responsible for producing male gametes and sexual hormones.

• Sperms are produced in the seminiferous tubules of the testes, which are divided into about 300 lobuli testis.

• The duct system of the male reproductive system is made up of tubuli recti, rete-testes, ductuli efferens, ductus epididymis, ejaculatory duct, and urethra.

• The vas deferens has a well-developed muscularis with a thin inner longitudinal layer, a thick middle circular layer, and a thinner outer longitudinal layer.

• The penis has a pair of copora cavernosa and corpus spongiosum, which surrounds the urethra and ends in the glans penis.Histology of Reproductive Organs

• The penis has three cavernous bodies: two dorsal-lateral corpora and a single mid-ventral corpus spongiosum.

• The tunica albuginea surrounds the corpora cavernosa and the corpus spongiosum, and all three are bound together by loose connective tissues.

• The core of each corpus cavernosum is occupied by numerous trabeculae consisting of collagenous fibres, elastic fibres, and smooth muscles.

• The cavities of the corpora cavernosa are lined with endothelium and receive blood from the dorsal arterial system and the central deep arteries.

• The urethra in the shaft of the penis is designated as the spongiosa part or cavernous urethra.

• The seminal vesicle is an elongated sac with a highly convoluted irregular lumen, consisting of complex primary and secondary folds.

• The epithelium of the seminal vesicle is usually a low pseudostratified with some basal cells and short columnar or cuboidal cells that are secretory but not ciliated.

• The muscularis of the seminal vesicle is more or less in the form of an inner circular and an outer longitudinal layer.

• The internal female reproductive organs are the ovaries, oviduct, and vagina, while the external are the labial minora and majora, clitoris, and vestibule.

• The wall of the vaginal canal consists of three layers of tissue: mucosa, muscular layer, and adventitia.

• The endometrium is the innermost layer of the uterus, effectively the mucosa of the uterus, composed of a simple columnar epithelium, a thick lamina propria, and tubular glands that extend deep into the lamina propria.

• The myometrium is a tunic of smooth muscle that surrounds the endometrium and consists of four poorly defined layers of smooth muscle.
