Question

1.where does sperm fully mature

2.during oogenesis , meiosis II is only complete if fertilization takes place True or False

3.How many polar bodies are produces during spermatogenesis

4.During ejaculation which of the followinf atructures does sperm pass through immediatly after leavinf the vas differents

a. prostatic urethra

b. spongy urethra

c. ejaculatory ducts.

d. epididymis.

Answer 1

1. sperms cells mature primarily in the head and body of epididymis. they are stored in the tail. This entire process of maturation takes about 9 to 10 weeks.

2. TRUE. meiosis II is completed only if fertilization takes place, if when fertilized results in fertilized matured ovum and a second polar body. Its like egg is stuck in meoisis II until fertilization occurs.

3. 4 Polar bodies are fomred. Polar bodies are commonly called as the haploid spematids, 4 of them are formed during the meiosis from the first spermatocyte.

4. EJACULATORY DUCT.

sperm from the from seminiferous tubules comes to epididymis, after getting matured here, they go to tail, from tail it come to the vas deference then into the ejaculatory duct. This connects to the urethra, where they are ejacted out.
