Male Reproductive Flashcards
the organ used for urination and sexual intercourse. It has spongy tissue that can fill with blood to cause an erection. It contains the urethra, which carries both urine and semen.
Penis
this is a loose bag of skin that hangs outside the body, behind the penis. It holds the testes in place
Scrotum
these are a pair of egg-shaped glands that sit in the scrotum, on the outside of the body. They produce sperm and testosterone, which is the main male sex hormone
Testes
this is a highly coiled tube that lies at the back of the testes. All sperm from the testes must pass through here, where they mature and start to ‘swim’.
Epididymis
this is a thick-walled tube joined to the epididymis. It carries sperm from the epididymis up to the prostate gland and urethra
Vas deferens
this is a walnut-sized gland that sits in the middle of the pelvis. The urethra runs through the middle of it. It produces the fluid secretions that support and nourish the sperm.
Prostate Gland
this is a tube that extends from the
bladder to the external opening at the end of the penis. It carries both urine and sperm
Urethra
these are 2 small glands above the prostate
gland that make up much of the fluid in semen
Seminal Vesicle
This tissue contains thousands of
spaces. During sexual arousal, the spaces fill with blood, and your penis becomes hard and rigid (erection)
Erectile Tissue
This tissue is responsible for the production and secretion
of testosterone.
Intestitial Tissue
This tissue is composed of acini and ducts lined by three types of cells: luminal, basal, and neuroendocrine
Grandular Tissue
These are the stem cells in the testes that undergo mitosis to produce more of themselves or
differentiate into primary
spermatocytes
SPERMATOGONIA
These cells support and nourish
developing sperm cells within the
seminiferous tubules of the testes.
They also produce hormones and
regulate the process of
spermatogenesis.
SERTOLI CELLS
Found in the testes, They
produce testosterone in response to luteinizing hormone (LH) from the pituitary gland. Testosterone is
crucial for the development and
maintenance of male reproductive
tissues and secondary sexual
characteristics.
LEYDIG CELLS
These are the mature male
reproductive cells produced
through spermatogenesis. They
carry genetic material and are
capable of fertilizing an egg during
sexual reproduction
