Male Anatomy Flashcards
Nada
Know the 3 glands associated with the male reproductive system, as well as Secretions and function of secretions
Seminal Vesicle: 60% of Seman, fructose, Prostaglandin ( Causes Female to contract to propel sperm up ) Alkaline
Prostate: Thin Milky secretions, 30% of Seman, Stickiness
Bulboeurthal gland: Precum and neutralizes the urine on the head of the penis
The embryo must have the ______ chromosome to become a male
Y
What is androgen-insensivity syndrome
Shows signs of puberty but doesn’t menstrate
Testies in the abdomen, XY Kareotype, Produce Testostrone Lack receptors, No Uterus
How many chromosomes do humans sex cells have? How does this number compare to other cells?
23
46
Which determines the sex of the baby the Sperm o Egg?
Sperm
What’s the function of the SRY gene?
TDF; testies determining factor, Codes for makes
The fetus gonads don’t start developing until _____ weeks
5 o 6
From which duct does the male reproductive tract develop?
Males mesoneohric duct development Paramesonephric Degenerate
Opposite in females
Testes start secreting testosterone at ______ weeks
8 o 9
The genital tubercle becomes what structure in males and females?
Penis o Clitorus
The urogenital folds become what structure in males and females?

The labioscrotal folds become which structure in males y females.
Scrotum o Labia Majora
The gonads for males are the _____ and for females are the _____
Testies in Males
Ovaries in Females
What are the 2 muscles of the scrotum and their function
Elevate and lower testies
Cremaster: Abdominal Oblique; Cold Temps Contracts and draws testies to body / Warm Temps let them hang.
Dartos Facia: Subcantenous Smooth, Contracts and wrinkles Testies reducing
What is the pampiniform plexus ?
Network of veins in the scrotum
Function to cool the testies
Testes are composed of ______ that produce sperm, and _____ that produce the hormone testosterone.
Seminferious tubules
Leydig Cells
What’s the function of sustentacular ( nurse ) cells?
Nourish, Protect, and remove waste from the Germ Cells
Know the order of ducts from which Sperm travels: Creation to Exit
Epididymis
Ductus (Vans) Defrins

What’s the function of GnRH and what organ secrets it?
Hypothalamus: Stimulates the Anterior Pituitary to Release LH & FSH
What is the function of LH & FSH
LH: aka ISH Stimulates interstitial endocrine cells to release testosterone
FSH: Stimulates Nurse cells to release androgen-binding proteins that bind to Test, Keeping it in the Seminifrious Tubules to stimulate Spermogenisis
What’s the function of Testosterone?
Inhibin?
General Body Growth
Secreted from Nurse Cells, Supresses FSH reducing Sperm production without reducing LH and testosterone secretion.
