Function of scrotum
• Temperature regulator • Houses and protects the testes
Function of testes
• Sperm production by terminal layer • Production of testosterone by interstitial cells
Cells of Leydig
Interstitial cells
What does the tasty consist of?
Compartments or globals that are high convoluted with tubes that form seminiferous tubs
Function of epididymis
• Matures sperm to become motile and fertile • Stores sperm
Function of sperm duct
Pushes mature sperm by strong peristaltic wave
Function of the copper gland
Produces alkaline mucus like fluid when sexually aroused 1. Neutralises acidic urine present in the urethra 2. Lubricates urethra and external urethral opening
Function of the prostate gland
Secrete fluid that aids the transport of sperm which contains enzymes that make the sperm more motile
Function of urethra
Forms a common duct for the transportation of semen and urine
Erectile tissue
• Corpus cavernosa (2 - dorsal) • Corpus spongiosum (1 - ventral)
Function of penis
Deposit semen with sperm into the vagina during copulation
Function of ovaries
1 form and release eggs 2. Produce estrone and progesterone
function of fallopian tubes
• Pathway from the uterus to the ovary for the egg, sperm and zygote • Site of fertilisation and initial cell division of your zygote • And developing zygote is moved to the uterus by the muscles and cilia
What is the function of the uterus
• Blastocyst implants, develops and gross • Contractions of your myometrium during birth
What muscles keep the cervix closed during pregnancy?
Sphincter muscle
What is your uterine wall made up of?
• Myometrium • endometrium
Function of vagina
• Sperm is deposited during intercourse • Birth canal
Define puberty
Process of physical and physiological changes
Define adolescence
Period of physical, physiological and psychological changes
How does puberty start?
The maturity gland is stimulated from your hypothalamus in which it release gonadtropins
Gonadtropin in males
Interstitial cell stimulating hormone Stimulates the testis to secrete testosterone
Gonadtropin females
Follicle stimulating hormone Ovaries to secrete oestrogen
What is an oestrous cycle?
It occurs when females ovulate and can be impregnated. If not impregnated mammals reabsorbed the endometrium
Gametogeneis
Formation of mature Gammys by the reproduction glands
