Dominic Luster Reproductive system
Testes
Interstital cells
Secrete testosterone under the influence of a luteinizing hormone.
Seminiferous tubules
Create sperm under the direction of gonadotropin.
Male & female homologues structures
Male
The gonads develop during week 5 structurally identical in both sexes and gonadal ridges are formed.
Testes are developed from the gonadal ridges.
The genital tubercle enlarges to become the penis.
The two labioscrotal swelling join in the mid line to become the scrotum.
Female
The gonads develop during week 5 structurally identical in both sexes and gonadal ridges are formed.
Ovaries are developed from the gonadal ridges.
The genital tubercle enlarges to become the clitoris.
The unfused urethral folds become the labia minora, and labioscrotal swelling become the labia majora.
Epididymis
Gives sperm the ability to propel them selves.
Gives sperm the ability to fertilize an egg.
Where sperm can mature
Spermatic cord
Structures: Testicular artery, vein, nerve, and the vas deferens.
Seminal vesicle
Decreases the female immune response
Adds a substance that liquefies and clots semen.
Increases sperm motility
adds nutrients
Porstate gland
Adds a substance that liquefies and clots semen.
adds nutrients
Bulbourethral gland
Secretes an alkaline mucus before ejaculation, neutralizes acid & lubricate's.
Male external genitalia
Scrotum
A pouch of skin that holds the testicles
Penis tissues
Smooth muscle, vascular tissue, and an enlargement of spongy tissue.
Ovarieis
Is where the maturation of an oocyte occurs under the influence of (FSH)
Secrete estrogen and progesterone.
Uterine tube:
A passageway for the ovum, sperm, and embryo. (Ovum + sperm = zygoat)
Peristalsis & cilia
Helps with movement through the uterine tube.
Menstrual cycle
Last's for 28 days
Uterus
Perimetrium
Inner layer of serious membrane.
Myometrium
Middle muscle layer that contracts during child birth.
Endometrium
Functional layer, is shed every month
Basal lay, function is to replace the functional layer
Vagina
Has rugae which makes it highly distensible (ability to stretch).
Receives penis and sperm during intercourse.
Semen
Is sperm and secretions from the seminal vesicles & prostate gland.
Female external genitalia
Mons Pubis
Fat pad that sits over hte pubic symphysis.
Mammary gland
Modified sweat gland that produces milk.
Labia minora
Inner folds of the vulva
Clitoris
Erectile part of the female genitals.
Labia majora
Outer fold that protect the rest of the external genitalia.
