Reproductive System Flashcards
Head of sperm that contains enzymes that facilitate the penetration of a sperm into a secondary oocyte
The Acrosome
Gonads
Produces gametes and hormones.
The ovary in F and the testis in M
Scrotum
Skin covered pouch that contains the testes
Testes
M gonad that produces sperm and hormones testosterone and inhibin
Tunica Albuginea
Covers the testis, penis, ovary
Seminiferous tubules
Where sperm is produces
Sustentacular or Sertoli cells
A cell type located in the seminiferous tubules that supports and protects spermatogonia
Blood-testis barrier
Formed by the sustentacular cells that prevents an immune response against antigens that spermatogenic cells produce.
Leydig cells
Secretes testosterone
The condition of undesended testes
cryptorchidism
How long does spermatogenesis take?
65-75 days.
What two reproductive hormones does the Anterior Pituitary gland release?
FSH and LH
What does GnRH stand for?
Gonadotropin Releasing Hormone
How does FSH and LH help the reproductive system in F and M?
Supports ovulation in F
Sperm production in M
PRL
Prolactin
Prolactin
Stimulates mammary glands to produce milk
What temp is ideal for sperm production?
2-3 degrees Celsius below body temp
What are the spermatogenic cells in sperm maturation?
Spermatogonium (2n)
Primary spermatocyte (2n)
Secondary spermatocyte (n)
Spermatid (n)
Sperm (n)
Stages of sperm maturation
Mitosis, differentiation, Meiosis 1- DNA replication, Meiosis II- chromosome (2n) separating into chromotids (n), Sperm
Process of spermatids to sperm
Spermiogenisis
How does the acrosome work?
It has enzymes such has hyaluronidase and proteases to help sperm penetrate the female secondary oocyte
