Testes
Spermatozoa
Spermatids
Spermatogonia
This membrane extends inward, forming septa that divide the testes into lobules
Tunica vaginalis
Tunica albuginea
Epididymis
Scrotum
Reorder the following cells from least mature to most mature
Spermatogonia
Primary spermatocyte
Secondary spermatocyte
Spermatid
Spermatozoa
This cells form a tight junction at the blood-testis barrier, preventing an immune response against sperm cell surface antigens
Astrocyte
Sertoli cell
Leydig cell
Lobule
How long does spermatogenesis take?
65-75 days
55-65 days
45-55 days
35-45 days

Lysozomes
Acrosomes
Nucleus
Mitochondria

12 hrs
24 hrs
36 hrs
48 hrs
Puberty increases the release of this hormone
GnRH
FSH
LH
Testosterone
LH acts on which cells of the testes?
Spermatozoa
Leydig cells
Sertoli cells
Primary spermatocytes
Testosterone and FSH stimulate Sertoli cells to secrete this, in order to keep testosterone concentrations high
Testosterone
Dihydrogen Testosterone (DHT)
Androgen binding protein
Cholesterol
High blood concentration of testosterone does what to the release of GnRH?
Stimulates
Inhibits
No effect
Reorder the following ducts in the order that a sperm cell would travel through them
Seminiferous tubules
Straight tubules
Rete testis
Efferent ducts
Ductus epididymis
The ductus deferens conveys sperm via
peristalsis
hydrostatic pressure
osmotic pressure
gravity
It is thought that the seminal vesicles excrete this monosaccharide to fuel the mature sperm because it is not used anywhere else in the body, and thus has no competition for usage
(a)
This secretes alkaline fluid in order to neutralize the acidic environment of the vagina
Prostate
Seminal vesicle
Bulbourethral gland
Testes
