Term
|
Definition
| The distal enlarged end of penis. |
|
|
Term
|
Definition
| There are (3): two corpus cavernosa, & one corpus spongiosum. |
|
|
Term
|
Definition
| Separates the two corpus cavernosa. |
|
|
Term
|
Definition

|
|
Term
|
Definition
| Layer in the penis that surrounds all three of the erectile tissues. |
|

|
|
Term
|
Definition
| The proximal enlarged end of penis. |
|
|
Term
|
Definition
| There are (3): The seminal vesicles, prostate gland, & bulbourethral gland. They contribute alkalie secretions to the seminal fluid, which stimulates sperm motility. |
|
|
Term
|
Definition
| The enlarged terminus of the vas deferens. |
|
|
Term
|
Definition
| Temperature sensative so it raises & lowers the testis to maintain an internal testicular temperature of 94-95 degrees F. Higher temps will stop the spermatozoa from maturing. |
|
|
Term
|
Definition
| Contains vas deferens, nerves, & blood vessels that supply the testis. |
|
|
Term
|
Definition
| A tube the mature spermatozoa leave the epididymis through and travel to the common ejaculatory duct. This occurs when ejaculation happens. Also vas deferens is the central canal of the spermatic cord. |
|
|
Term
|
Definition
| Pouch on the posterior exterior surface of testes. Where the mature spermatozoa are stored. |
|
|
Term
|
Definition
| The joining of the seminiferous tubules make the rete tesis. Spermatozoa travel through them to the epididymis. |
|
|
Term
|
Definition
| They are coiled up inside the chambers of the testes and produce spermatozoa. Spermatogonia are near the basement membrane. Mature sperm cells are near the lumen. They contain sertoli cells (sustentacular cells) inside them. |
|
|
Term
|
Definition
| The Primary sex organ of the male reproductive system. |
|
|
Term
|
Definition
| Double layered serous membrane that partially surrounds each testis. |
|
|
Term
|
Definition
| A sac the testes lie in. The outer skin of the testes. |
|
|
Term
| Leydig cells (Interstitial cells) |
|
Definition
| Secrete (make) testosterone. These cells surround the seminiferous tubules. |
|
|
Term
| Sertoli cells (Sustentacular cells) |
|
Definition
| sertoli cells function properly from the binding between testosterone & receptors in the sertoli cells. testosterone is converted into two other steroids in the sertoli cell, they are DTH & Estrogen. These cells also secrete a protein called androgen-binding protein into the seminiferous tubules. |
|
|
Term
|
Definition
| The discharge of the secretions of the seminal vesicles, prostate gland, & bulbourethral glands with sperm cells from the epididymis into the urethra to form semen. |
|
|
Term
| Mucous secretion just before Ejaculation |
|
Definition
| Bulbourethral glands & urethral mucous glands produce a mucous secretion before ejaculation which lubricates the urethra to neutralize it from its normal acidity. The accessory glands provides small amount of lubrication during intercourse and help to reduce vaginal acidity. |
|
|
Term
|
Definition
| Forceful expulsion of semen from the urethra caused by the contraction of the urethra, & muscles in penis. |
|
|
Term
|
Definition
| 4 fused carbon rings plus side chains. Lipid based. Diffuse through phospholipid bilayer, binding to intracellular receptor. (testosterone is a steroidal hormone). |
