Testicles descend through the…
inguinal ring
How Do The Testes Get To The Scrotum?
Develop inside abdomen
Gubernaculum Runs from its caudal pole to scrotal sac, which pulls the testis through the inguinal canal and reaches scrotum by early
neonatal life
Cryptorchid
One or both
testicles retained
Monorchid
Only one testicle developed
Each testicle is wrapped in a double layer of peritoneum known as the..
Tunica vaginalis
Pampiniform plexus
seminiferous tubules
Blind ending tubules within the testis
where are Spermatogenic cells and Sertoli cells located
seminiferous tubules
seminiferous tubules all drain into larger collecting ducts and lead to the…?
Epididimus
Function of Cells of
Leydig (Interstitial cells)
Secrete testosterone
Epididymis
This acts as a storage area for the sperm
Vas Deferens
(spermatic cord) carries the sperm from the epididymis to the urethra
the spermatic cord (Vas deferens) contain (3)
- Testicular artery and vein
- Nerve
- Cremaster muscle
Accessory Glands
Prostate
Bulbo-urethral Gland(cats only)
Prostate
produces a milky white fluid that forms a large part of the
seminal fluid
aids the survival of sperm
Structure of the penis
Root, body and Glans and Os penis
Bulb of the penis (or bulbus glandis)
erectile tissue
Corpus spongiosum penis
erectile tissue surrounding the urethra
