Leydig Cells |
Acted on by LH (leutinizing hormone) to produce testosterone. Found outside the seminiferous tubules. |
|
Lumen of Seminiferous tubules |
Central cavity of the tubules into which mature sperm are released. |
|
Primary Spermatocytes |
Diploid cells that undergo the first meiotic division to give rise to secondary spermatocytes. Located closer to basal surface of seminiferous tubules. |
|
Seminiferous tubules |
Tightly coiled structures in which the sperm develop. Located within the testes. |
|
Sertoli cells |
"Nurse" cells that nourish developing sperm and anchor spermatids during maturation. Respond to FSH (follicle stimulating hormone) to initiate spermatogenesis. |
|
Spermatids |
Haploid cells that undergo spermiogenesis to become mature sperm. Closer to lumen of seminiferous tubules. |
|
Spermatogonia |
Diploid cells that undergo mitotic division to give rise to primary spermatocytes. Found along the basal surface of the seminiferous tubules. |
|
Tunica albuginea |
Connective tissue surrounding the seminiferous tubules portion of the testes. |
|
Antral follicle (vesicular follicle) |
Developing follicle w/ small pockets of antral fluid developing within the layers of follicle cells. |
|
Antrum |
The fluid-filled space found in antral or Graafian follicles; also called the follicular cavity. |
|
Graafian follicle |
Mature follicle containing a large fluid -filled antrum. |
|
Primary follicle |
Developing follicle containing a primary oocyte surrounded by a single layer of cuboidal follicle cells. |
|
Primary oocyte |
The form of the developing oocyte from 3 months of human fetal development until meiosis resumes shortly before ovulation. |
|
Primordial follicle |
Non-growing follicle containing a primary oocyte stalled in prophase of the first meiotic division and surrounded by a single layer of flattened follicle cells. (Meiotic arrest until puberty). |
|
Secondary follicle |
Developing follicle containing a primary oocyte surrounded by more than one layer of follicle cells, BUT NO ANTRUM. |
|
Zona pellucida |
Acellular material secreted between the oocyte and follicle cells. |
