GU Flashcards
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 and secrete inhibin which enhances FSH biosynthesis and secretion
5
Q
what are Peritubular Miotubular cells?

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
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 with the contents of the hernia compressed to the extent that the bowel lumen is no longer patents and causes bowel obstruction
20
Q
what is a strangulated hernia?

Inguinal hernia
22
Q
Describe the path of the inguinal ligament
A
the inguinal ligament runs between the AAS IIS and the pubic tubercular/ this forms the inguinal canal/ inguinal canal allows for the passage of the spermatic cord and the round ligament as well as the 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 a direct from an indirect hernia?
If you press on whether deep inguinal ring is and you can reduce the hernia then it means it is an indirect hernia

130
what is benign prostatic enlargement/hyperplasia?
There is smooth muscle hyperplasia causing prostatic enlargement symptoms also arise because of central nervous system dysfunction and blood flow dysfunction
131
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 where it binds to receptors inside the prostate cells causing them to increase their secretions and increase cell division eventually resulting in gland enlargement

141
What are side effects of alpha blockers?
Anterograde ejaculation dizziness hypertension
142
how do alpha blockers work in terms of BPH?
Is an alpha one adrenoceptor antagonist so relaxes smooth muscles
143
how do five alpha reductase inhibitors work?

162
what muscle allows for micturition?
detrusor
163
Describe the physiology of micturition
the detrusor muscle fills and stretches allowing for a constant intra-vesicular pressure (known as stress relaxation) / urine is passed through parasympathetic control / using pelvic nerves S2 – four releasing a CH which works on M3 muscarinic receptors causing the detrusor muscle to contract there is also inhibition in a different pathway resulting in the re-used sympathetic stimulation of the inner urethral sphincter causing relaxation in females urination is assisted by gravity whereas in males there is bulbospungiosus contractions

and increased production of fluid by the tunica vaginalis / reduce resorption of fluid / impairment in lymphatic drainage
185
what is the pathophysiology of communicating hydrocele?
they communicate with the peritoneum due to a patented processus vaginalis / these can change in size when standing versus lying down/ due to increased intra-abdominal pressure

During the newborn baby check the scrotum is checked to see if the testes are palpable
200
what are palpable undescended testes?
Most common type of undescended testes are palpable ones usually within the upper portion of the scrotum or the inguinal canal during the exam the testicle can be felt and looked down into the scrotum (retractile)
201
are retractable test is considered normal?
Yes they do not require surgical intervention
202
