human reprodcutive system
occurs when the sperm are transferred directly to the females body, and the secondary oocytes are fertlized inside of the females body
is when the embryos are retained in the females body.
sperm cells containt three parts
the head of sperm
is the body of the sperm cell
it contains the nucleus and is tpped with the acrosome
is compesed of granulare enzymes to dissolve the zona pellucida wich surrounds the secondary oocyte
contains mitochondria for energy production
the falgellum below the midpiece
it propels the sperm cell
male copularoty organ and contains eretile tissues
these tissues engorge with blood during an erection
located the length of the penis and orsally to the urethra
this tssur makes up the bulk of the penis
is located the length of the penis beneath the corpora cavernosa
it encircles the urethra
contain a series of lobules which contain the seminiferous tubules
the lumen of the tublules are lined with seminiferous epithelilum which prodcues the spermatieds.
intersitial cells which produce testosterone are also associated with lobules
this structure is an external sac of skin and smooth muscle containing the testes. associated smooth muscles raise and lower the scrotum to control the temperature of sperm
these are the primary reproductive organs of males. they produce sperm and hormones like testosterone
these are a series of convoluted ducts combining inot a comman shapred organ located on the posterior surface of eaxh testies
spermatids differentiate into sperm and are stored n the epididymis
these ducts connect the epididymis with the ejaculartory ducts
they sereve as sites for sperm storage and cnduct sperm to the ejaculatory ducts druintg an ejaculation
these are short ducts formed by the merging of the ducts from the seminal vesicle and the vas deferens.
they condut sperm to the urtethra
this is a large tuve connectind the urinary bladder with the distal end of the penis.
it conducts both sperm and urine. although not at the same time
these sac like glands are about 5cm long
their ducts empty into the ductus deferens
they produce about 60% of the semens volume
this is a gland surrounding the urethra where it exits the bladder.
it prodcues about 30% of the semens volume
these are a pair of small glands located laterally o the urethra posterior to the prostate gland.
they produce an alkaline mucus which lubercates the head of the penis
