When does the reproductive system begin its biological function?
What are the essential organs for reproduction in the male?
What are the essential reproduction organs for a female?
What produces the sex cells, gamates, and sex hormones?
Testes in males, ovaries in females
What are the males reproductive roles?
Manufacturing sperm which gets taken to the female reproductive tract
What are female reproductive roles?
Where do the paired oval testes lie?
In the scrotum behind the adominopelvic cavity.
What is the temperature of the testes? Why?
94 degrees. This is to ensure viable sperm production
What structures make up the duct system in males
epididymis , ductus deferens, ejaculatory duct, urethra
an elongated structure running up the posterolateral aspect of the testis ending at the superior aspect
Forms the first portion of the duct system - Site for immature sperm to complete their maturation process
The . sperm duct
arches superiorly from the epididymis Passes through the inguinal canal into the pelvic cavity and courses over the superior aspect of the urinary bladder Enclosed along with blood vessels and nerves in a connective tissue sheath called the spermatic cord
Terminus of the ductus deferens enlarges to form the region, ampulla, which empties into the
What are the steps of ejaculation?
contraction of the ejaculatory duct propels sperm through the prostate to the prostatic urethra which empties into the intermediate part of the urethra and then into the spongy urethra, which runs through the length of the penis to the body exterior
The liquid medium in which sperm leaves the body
Accessory glands for males
The prostate, seminal glands, and bulbo- urethral glands
What do the male accessory glands do?
produce seminal fluid
consists of sperm and seminal fluid
What is special about semen?
It is alkaline and provides a buffer against the acidity of the femal vagina.
What is the physiology behind a man getting an erection?
Internally, the penis consists of three enlogated cylindes of erectile tissue which engorge with blood during physical activity.
Paired glands located posterior to the urinary bladder
A duct from each one of these glands merges with a ductus deferen which forms the ejaculatory duct
Single gland that encircles the prostatic urethrea inferior to the bladder
Paired tiny glands that drain into the intermediate part of the urethrea
Bulbo urethreal glands
The dense connective tissue capsule that covers each teste
Sperm forming factories
What are the sex hormones of females?
Estrogen and progesterone
Where are the sex hormones of females produced?
