10-15
Describe the course of blood through the kidneys
Renal artery ->
How many layers are present in the muscularis propria of the urinary bladder
3
What epithelium lines the prostatic urethra
proximal - pseudo-stratified columnar (urothelium)
Distal - Non-keratinised stratified squamous (male and female)
On what part of the urethra in males and females are the external urethral sphincter found
Over the membranous urethra
What structure is found under the urothelium of the prostatic urethra
Dense fibrous connective tissue
Where is the bulbourethral gland located
In the membranous part of the urethra.
What is the bulbourethral gland equivalent in females
Bartholin Glands
What epithelium lines the seminiferous tubules
columnar epithelium and sertoli cells - germinal epithelium
What cells form the blood testis barrier
Sertoli cells
What epithelium lines the epididymis
Pseudo-stratified columnar epithelium with stereocilia
Why do the epididymis have stereocilia
For absorption
