The first stage of Haploid spermatogenisis
and the first stage of haploid oogeneis |
Meiosis I, where the secondary spermatocytes are produced.
In oogeneis, first haploid stage is meiosos I produces secondary oocyte. |
|
|
How is sperm transported within the testes
|
Pressure generated by fluid secreted by Sertoli cells pushes sperm & fluid along lumen of semiferious tubules
staight tubules. rete testis efferent ducts in the epididymis ductus epididymis. |
|
|
What are the male reproductive ducts
|
Ducts of testes, epididymis, Ductus deferens (AKA vas deferens) spermatic cord, ejaculatory duct, urethra
|
|
|
parts of the spermatic cord
|
ductus deferens, testicular artery, veins, autonomic nerves, lymphatic vessels, cremaster muscle
|
|
|
Prostatic secretions
|
Slighty acidic fluid that contains citric acid, proteolytic, enzymes, acid phosphate, seminal plasmin (antibiotic)
|
|
|
What happens during erection and ejaculation in the corpus spongiosum penis
|
The corpus spongiosum penis contains erectile tissue which relaxes allowing blood vessels to dialate
Nitric Oxide cause muscle within to relax wich results in the widening of the blood sinuses. The corpus spongiosum penis holds urethra open during ejaculation. |

Describe the route of milk from the alveoli to the nipple
|
alveoli
secondary tubules mammary ducts laciferous sinuses lactiferous ducts nipples. |
|
|
What stimulate estrogen secretion
|
FSH and LH

2nd half of menstrual cycle where the corpus luteum secretes progesterone which prepares endometrium for implantation.
If fertilization doesn't occur, corpus lutem disintergrates and menstruation begins |
|
|
What is the function of the Mullerian-inhibiting
|
Secreted by developing Sertoli cells, causes apoptosis of cells within the mullerian ducts.
