|
|
Term
| ovarian cells from 2 layers which are: |
|
Definition
| theca interna (vascular layer) and theca externa (fibrous layer) |
|
|
Term
| Follicular cells continue to proliferate eventually form a space-filled with fluid (antrum) - with the ooctye pushed to one side. |
|
Definition
|
|
Term
| What's a mature/graafian follicle? |
|
Definition
| it's a follicle with a large ANTRUM that bulges out of the ovary & contains a secondary oocyte |
|
|
Term
| Ovulation occurs due of WHICH HORMONE and what does the hormone cause? |
|
Definition
LH
and it weakens the mature follicle wall |
|
|
Term
| During ovulation, eventually LH causes the wall to rupture and the secondary ooctye enters WHERE |
|
Definition
| it enters the pelvic cavity into the opening of the uterine/fallopian tube |
|
|
Term
| Oocyte must be fertilized within HOW MUCH TIME of ovulation or else it will degenerate |
|
Definition
|
|
Term
| Male sex cells are BLANK and female sex cells are BLANK |
|
Definition
| Male sex cells are sperm, Female sex cells are oocytes |
|
|
Term
|
Definition

Term
|
Definition
|
|
Term
|
Definition
| one set of chromosomes (23) and 2N DNA due to sister chromatids |
|
|
Term
|
Definition
| chromosomes line up at metaphase plate |
|
|
Term
|
Definition
|
|
Term
|
Definition
| each cell divides again into 2 now containing 23 chromosomes and 1N DNA |
|
|
Term
| What's the primary sex organ in males? |
|
Definition
|
|
Term
| What happens in the testes? |
|
Definition
| sperm production and sex hormones are formed |
|
|
Term
| All male structures are accessory sex organs except: |
|
Definition
|
|
Term
|
Definition
| it is fibrous cord that anchors the testes (attaches to each testis scrotum) |
|
|
Term
| each testis has three things: |
|
Definition
| ductus/vas deferens, nerves, and blood vessels |
|
|
Term
|
Definition
| connective tissue that extends into testes |
|
|
Term
|
Definition
| contain spermatogenic cells (which are precursors to sperm( |
|
|
Term
| Interstitial/Leydig cells produce: |
|
Definition
|
|
Term
|
Definition
|
|
Term
| Sertoli cells are supporting cells in the |
|
Definition
| seminiferous tubules, support and nourish developing sperm (spermatozoa) |
|
|
Term
Spermatogonia are:
*SPERM PRODUCTION* |
|
Definition
undifferentiated spermatic cells; contain 46 chromosomes
-Type A give rise to more spermatogonial cells
-Type B differentiate into sperm |
|
|
Term
|
Definition
|
|
Term
|
Definition
| the name for when sperm's being produced yooo! |
|
|
Term
| Spermatogenesis occurs from the base of the epithelium in the BLANK into the BLANK |
|
Definition
| Spermatogenesis occurs from the base of the epithelium in the SEMINIFEROUS TUBULES into the LUMEN |
|
|
Term
| What cells from the blood-testis barrier for developing sperm? |
|
Definition
|

|
Definition
|
|
Term
|
Definition
| process of sperm maturation; occurs through the seminiferous tubule into the epididymus |

|
Definition
| it is still within that circle shaped cell membrane. |
|
|
Term
| What's mature sperm consist of? |
|
Definition
Flattened head, midpiece/body and tail
Head consists of nucleus with 23 chromosomes
Midpiece contains many mitochondria and filaments
Tail is a flagellum that consists of microtubules
