|
|
What cell types line tubuli recti? (2)
|
1st half= Sertoli cells
2nd half= simple cuboidal epithelium |
|
|
What cell type lines rete testis?

|
|
What are the 2 cell types found in the epididymis?
|
1. Basal cells
2. Principal cells |
|
|
What is the role of basal cells (in epididymis)?
|
Thought to be stem cells
|
|
|
What is the role of principal cells (in epididymis)? (3)
|
1. Resorb luminal fluid
2. Phagocytose cytoplasmic remnants 3. Prevent activation of sperm |
|
|
How are spermatozoa conduct from epididymis --> ductus deferens?
|
Smooth muscle cells surround epididymis which allows peristaltic waves
|
|
|
What cell type lines the ductus deferens?
|
Pseudostratified epithelium w/ stereocilia
|
|
|
What are stereocilia?
|
Microvilli
|
|
|
What forms the ejaculatory duct?
|
Joining of ductus deferens w/ duct of seminal vesicle
|
|
|
How many layers of smooth muscle does vas deferens contain?
|
3 layers of smooth muscle
|
|
|
Where is the ejaculatory duct found?
|
Within the prostate & drains to urethra
|
|
|
What is different from the ejaculatory duct compared to the epididymis & ductus deferens?
|
No smooth muscle in its walls
|
|
|
What do seminal vesicles secrete?
|
Seminal fluid-- fructose rich --> energy for sperm
|
|
|
What type of glands are found within the prostate?
|
Tubuloalveolar glands-- secrete white serous fluid rich in lipids & enzymes
|
|
|
What is secreted by the bulbourethral glands? (Cowper's gland)
|
Thick, slippery fluid that serves as lubricant
|
|
