Back 9

Spermatocytogenesis;
Spermatogonia (A&B) --> Pale A --> Pale B --> Primary Spermatocyte

Front 10

Primary Spermatocyte turns into Secondary Spermatocyte Via Meiosis 1 and Seconardy Spermatocyte turns into __________ via Meiosis 2.
Name the Chromatid + Chromosome # in each.

Back 10

Spermatid = 23, 1n
Secondary Spermatocyte = 23,2n
Primary Spermatocyte = 46 4n
Spermatogonia = 46, 2N

Front 11

Final step from Spermatid --> ________

What is the name of this process?

Back 11

Spermatozoa

Spermiogenesis

Front 12

Spermiogenesis is divided into 4 phases, name the 4 phases.

What phase does the flagella form? when is the Manchette Mitochondria stretched

Back 12

GCAM
Golgi -preacrosome granules --> acrosome granules
Cap - Acrosome granules --> Acrosome
Acrosome (flagella)
Maturation (manchette)

Front 13

Late spermatid is released into the Seminiferous Tubules (cant swim) and it goes to the Rete testes via

Back 13

Testicular fluid released by the Sertoli cell

Front 14

when the late spermatid reaches the rete testes it will enter the Ductus Efferentes.

The ductus efferentes enter the epididymus to make Dutucs Epdidymus.

The ductus Epididymus tubules will merge to form one tube called the ____ ____. And the late spermatid will travel to this tube via ________.

Back 14

Ductus Deferens

Peristalysis

Front 15

Late spermatids' cytoplasm are linked together via _____ _____. Spermatozoa has lost this structure. Nonetheless spermatoza still cannot swim.

Back 15

Residual bodies in the Late Spermatid but not in the spermatozoa.

Front 16

Sertoli cells are bound to each other via ______ junctions. This separates the basal comparment and the lumenal comparment- this is called the ____ ___ ____

Back 16

Tight junctions (zona occludens)

Blood Testes Barrier

Front 17

Name six functions of the sertoli cells

Back 17

1. Support/protection(BTB)/nutrition
2. Phagocytosis of residual bodies
3. Secretion of fluid for sperm transfer from ST --> RT
4. Production of Androgen Binding Protein (binds to testosterone)
5. Production of ANTI-MULLERIAN-hormone
6. Secrete Activin and Inhibin

Front 18

Which cells can be found in the interstitial tissue between the seminiferous tubules?
What do they secrete?
Are they basophilic of aciophilic?

Back 18

Leydig cells- respond to LH
Secrete Testosterone- become active at puberty
They are pale acidophilic cells.

Front 19

Inhibin and activin act on ___. and are produced by ____.

Back 19

Basophilic Anterior pituitary gland
Sertoli cells

Front 20

Why do males need FSH LH?

Back 20

FSH stimulate sertoli cells to release ABP
LH stimulates Leydig cells to secrete Testosterone.
