Urogenital System

Explanation-
Spleen, Pancreas, Stomach-related to left kidney

Reference: Langman’s 13th; P-32

Membranous part is the shortest part of male urethra

Urethra lies in deep perineal pouch.

After formation, the spermatozoa are stored within the head of the epididymis. 

Spermatogenesis: The process of maturation of primordial male germ cell to mature sperm.
Onset: At puberty and continues up to old age.
Site: The wall of the convoluted seminiferous tubule 
Temperature required: 32 C.
Storage site: Head of epididymis.
Duration:
In man, the process of spermatogenesis requires 74 days, and passage through the epididymis approximately another 12 days. Therefore, it takes (74 days + 12 days) for a sperm for complete maturation and to be available for ejaculation.

Normal position of uterus is Anteverted and anteflexed

In the distal convoluted tubules of the renal cortex, PTH stimulates Ca2+ reabsorption (and inhibits phosphate reabsorption in the proximal tubules).

74 days is required for spermiogenesis.

Abnormal sites of implantation:
1. Ampullary region of the tube (80%, most common site of ectopic pregnancy)
2. Tubal implantation (12%)
3. Abdominal cavity (commonly in pouch of Douglas)
4. Internal os of uterus
5. Ovary
6. Mesentary

Most common site of ectopic pregnancy is Abdominal cavity

Site of spermatogenesis in male- Seminiferous tubule
