List the 2 male intratesticular genital ducts
What is the function of the straight tubules? and how is the sperm transported? |
Striaght tubules (tubului rete)Recti and rete testes
Straight tubules connect the Seminiferous tubules with the rete testes and sperm is transported via fluid secreted by the sertoli cells. |
|
|
list the 5 male excretory genital ducts
|
Distal part of Ductuli effrentes
ductus epididymis Vas (ductus) Deferens Ejaculatory Duct Urethra |
|
|
Striaght tubules and Rete Testes are both lined by what type of epithelium?
|
Simple cluboidal
|
|
|
Ductuli efferentes are lined by 2 types of epithelium and smooth muscle.
Name the types of epithelium and the purpose, and name the purpose of the smooth muscle. |
Tall columnar Cilliated cells- pushes the sperm towards the vas (ductus deferens)
Short non-cilliated cells - absorption of the fluid from ST Smooth muscle = peristalysis |
|
|
Sperm can now swim in the _______ _______, this is also a storage site for sperm.
|
Ductus Epididymus
|
|
|
Ductus Epididymus is lined by what type of epithelium? And it also has a circular muscular layer to assist the spermatozoa traveling along the Vas ductus epididymus.
It also Consists of 2 types of additional cells called ?? |
Pseudostratified Columnar Epithelium with sterocillia
Primcipal cells with sterocillia - reabsorb remaining fluid in testes. Secrete glycoproteins for sperm maturation and motility and glycerophosphocholine with inhibits capacitation so sperm cant fertilize- until they reach the oocyte. Basal cells - stem cells |
|
|
Ductus deferens has what type of epithelium (same as Ductus epididymus). And it also has three muscle layers-
inner middle outer |
Pseudostratified Columnar Epithelium with sterocillia
inner- long middle - circular outer - long These function to push the sperm along the dcutus deferens- |
|
|
Accessory Genital Glands -
This one develops as an outgrowth from the ductus Deferens - and its secretions make up 70% of the ejaculate- |
Serminal Vessicle
|
|
|
Seminal vessicle has three wall layers-
And what type of epithelium- same as ductus deferens and Ductus Epididymus- except... |
Mucosa- muscularis (inner ciruclar-outer long) and adventitia
Pseudostratified Columnar Epithelium - except no cilia it looks like the honeycomb branching |
|
|
This gland consists of 30-50 tubuloalveolar glands- and its duct empties into the ______ _____.
It also has three zones - peripheral --> Trabsitional --> Prostatic Urethra |
Prostate Gland-
Prostatic urethra Peripheral --> Prostate Cancer Transitional --> benign hypertrophy Prostatic Urethra- Tubuloalveolar glands |
