wheres the true pelvis vs the false pelvis?
above the pelvic brim,
below the pelivc brim contains the ileum and sigmoid colon
What is the exocrine function of the testes?
sperm and semen production
What is the endocrine function of the testes?
What cells make testosterone?
Where is sperm produced? Where does it exit? What does it travel through to get there?
seminiferous tubules of testis, duct system, penis
Where is sperm stored?
When exiting the seminiferous tubules what path does the sperm take to exit?
straight tubules -> rete testis -> efferent tubules -> epididymis ->ductus (vas) deferns -> ejaculatory duct -> prostatic urethra ->penile urethra -> outside
What does the prostate supply to semen?
milky slightly acidic fluid helps them to clot after ejaculation
What does the seminal vesicle contribute to semen?
fructose to provide energy (YUMMY! polina), proteins, citric acid, inorganic phosphorus, potassium, and prostaglandins
What is the outermost layer of the testes?
visceral tunica vaginalis, made up of peritoneum
What layer is located directly below the tunica vaginalis of the testes? What is made up of?
tunica albiguinea, thick dense CT
What is the function of the gubernaculum?
aids in the descent of the gonads (both testes and ovaries)
What is the function of the dartos muscle?
constricts the scrotum to increase the temp and raise towards the body and relaxes it to lower the scrotum away from the body to decrease the temp
What are the layers of scrotum? outermost-->innermost
1. skin 2. dartos muscle 3. colles fascia 4. parietal tunica vaginalis 5. tunica albiguinea
What is the is the central septum
divides the testis into bilateral compartments
what develops into the spermatic cord
vas deferens and its accompanying arteries, veins, nerves, and lymphatic vessels
what is the ac unit of the testis?
paminiform venous plexus
Where are the sertoli cells located?
descent of the testis give rise to
clinical significance of inguinal canal
weaker area around the the inguinal ring around the muscles of the pelvic floor => ingunial hernia
What is the structure of tunica vaginalis?
thin layer of CT covered by mesothelium
What is the structure of the tunica albiguinea?
thick layer of CT contains structure components of testis
the prostate is covered by what, why is this clinically relevant?
encapsulated glandular and fibromuscular tissue that holds the nerve responsible for erections
Most common benign prostatic enlargements
median and lateral lobes
Most commonly involved in prostatic adenocarcinoma
prostate digital exam
rectal examination of prostate for hardening, immovable prostate
benign prostatic hyperplasia
median and lateral lobes become enlarged => difficulty urinating
mostly affects posterior lobe
2nd leading cause of death in men
Label each part & know fnc
What is the epithelium of the tubuli recti made up of?
sertoli cells that become more cuboidal closer to rete testis
