(303 cards)
1
Q
what cells are found within the seminiferous tubules?
A
Germ cells
Sertoli cells
2
Q
what is the function of germ cells?
A
Allow the process of spermatogenesis
3
Q
describe the steps of spermatogenesis?
A
- spermatogonia
- spermatocytes
- spermatids
- spermatozoon
4
Q
what is the function of Sertoli cells?
A
- They are the true epithelium of the seminiferous epithelium
- support germ cell development
- secrete inhibin -which enhances FSH biosynthesis and secretion
5
Q
what are Peritubular Miotubular cells?
A
surround the seminiferous tubules and make up part of the smooth muscle
6
Q
where our Leydig cells found?
A
Within the interstitium
7
Q
what is a function of Leydig cells?
A
Secrete testosterone and other androgens as well as presenting macrophages
8
Q
what is the blood supply to the testicles?
A
testicular arteries however it also has collateral blood supplies
9
Q
describe the branching of the testicular arteries?
A
Arise from the abdominal aorta and descend through the inguinal canal
10
Q
what blood supply supplies the scrotum and the rest of the external genitalia?
A
external Pudinal artery and branches of the internal Ilac artery
11
Q
what is the venous drainage of the testicles?
A
Veins formed from the pimpiniform plexus in the scrotum
the left testicle drains into the left renal vein
the right testicle drains into the inferior VC
12
Q
what tests are good for imaging the upper urinary tract?
A
CT with contrast
or ultrasound scan
13
Q
when our ultrasound scans most commonly used when imaging the urinary tract?
A
in accident and emergency for acute situations as they have a lower sensitivity than CT
14
Q

A
Either CT or ultrasound
and cystoscopy of the bladder

17
Q
what does a reducible hernia mean?
A
When the contents of the area can be manipulated back into its original position
18
Q
What does an irreducible hernia mean?
A
the hernia is compressed by the defect causing it to be irreducible
19
Q
what is an obstructed hernia?
A
mainly refers to hernias containing bowel
contents of the hernia compressed to the extent that the bowel lumen is no longer patent
causes bowel obstruction
20
Q
what is a strangulated hernia?
A
The compression around the hernia prevents blood flow into the hernias’ content
causing ischaemia and tissue pain
21
Q
what is one of the most common causes of lump in the groin?
A
Inguinal hernia
22
Q
Describe the path of the inguinal ligament
A
- the inguinal ligament runs between the ASIS and the pubic tubercular
- this forms the inguinal canal
- inguinal canal allows for the passage of the spermatic cord, round ligament + ilioinguinal nerve
23
Q
what is a direct inguinal hernia?
A
A hernia caused by a weakness in the posterior wall of the inguinal canal
causes abdominal contents to enter the inguinal canal and go to the superficial ring
but does not pass through the superficial ring
24
Q
what is an indirect inguinal hernia?
A
the abdominal contents passes through both deep inguinal ring + through the inguinal canal to the superficial ring
25
what is an easy way to distinguish betweent a direct and an indirect hernia?
If you press on where deep inguinal ring is and you can reduce the hernia then it means it is an indirect hernia
26

symptoms also arising because of central nervous system dysfunction + blood flow dysfunction
133
describe the pathophysiology of benign prostatic enlargement
* Increase in the number of epithelial and stromal cells within the prostate gland
* usually within the transitional zone of the prostate
* testosterone is converted to dihydrotestosterone by five alpha reductase
* dihydrotestosterone receptors inside the prostate cells
* causing them to increase their secretions and increase cell division
