Testes
Interstital cells
Seminiferous tubules
Male & female homologues structures
Male
Female
The gonads develop during week 5 structurally identical in both sexes and gonadal ridges are formed.
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.
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.
The unfused urethral folds become the labia minora, and labioscrotal swelling become the labia majora.
Create sperm under the direction of gonadotropin.
Secrete testosterone under the influence of a luteinizing hormone.
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
Ovarieis
Penis tissues
Smooth muscle, vascular tissue, and an enlargement of spongy tissue.
A pouch of skin that holds the testicles
Is where the maturation of an oocyte occurs under the influence of (FSH)
Uterine tube:
Secrete estrogen and progesterone.
Menstrual cycle
Last's for 28 days
A passageway for the ovum, sperm, and embryo. (Ovum + sperm = zygoat)
Peristalsis & cilia
Helps with movement through the uterine tube.
Uterus
Perimetrium
Myometrium
Endometrium
Functional layer, is shed every month
Basal lay, function is to replace the functional layer
Inner layer of serious membrane.
Middle muscle layer that contracts during child birth.
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
Mammary gland
Labia minora
Clitoris
Labia majora
Fat pad that sits over hte pubic symphysis.
Erectile part of the female genitals.
Modified sweat gland that produces milk.
Inner folds of the vulva
Outer fold that protect the rest of the external genitalia.
