Flashcards in Chapter 02: Male Reproductive Deck (25):
What are densely packed sperm-producing proteins in the testis thta contain Sertoli cells and developing sperm cells?
What is located in the connective tissues between the seminiferous tubules that contain testosterone-producing Leydig cells?
What is Spermiation?
cytoplasmic bridges between adjacent spermatids are borken
What is Spermiogenesis?
Morphological differentiation and packaging protect chromosomes from environmental damage
Egg penetration (head)
What is the condition that prevents testes to descent during development?
What store testosterone dependent maturation of sperm and movement of the sperm through ducts due to peristalsis?
A. Ejactulatory Duct
B. Vas Deferens
D. Seminiferous Tubules
What transport sperm during ejaculation?
Label the following from the path of the sperm during ejaculation:
2. Vas Defernes
3. Ejaculatory Duct
4. Seminiferous Tubules
4, 2, 3, 1
What 3 things consits of Seminal Vesicles and what percentage of it is the semen value
Prostaglandins: stimulates contractions in female repdocutive tract
Fructose: primary energy source for sperm
Semenogelins/ Fibronectins: coagulate after ejact. To form gel matrix
What 2 things consist of the Prostate and what percentage is the semen volume?
Buffers: alkaline pH promotes viability of sperm
Prostate-specific antigen (PSA): enzyme breakdown of gel matrix to release sperm
What is in the Bulbourethral Gland and what percentage is its semen volume?
Mucus: aids lubrication during intercourse
What is the total time for spermatogonium to spermatozoa and how many sperm is produced each day?
64-74 days asynchornous; 100-200 million
How come sperm is stored in epididymis for several days?
Low metabolic demand; inactive
What is the difference between Oligospermia and Azoospermia?
Oligospermia has a low sprem count when ejaculated
Azoospermia has no sperm cells when ejaculated
