The terminal portion of the ejaculatory duct may be sclerotized to form the intromittent organ, the aedeagus. The remainder of the male reproductive system is derived from embryonic mesoderm , except for the germ cells, or spermatogonia , which descend from the primordial pole cells very early during embryogenesis.
It may contain 10–15 transverse small ducts or tubules that lead to the Gartner's duct (also longitudinal duct of epoophoron) that represents the caudal remnant of the mesonephric ducts and passes through the broad ligament and the lateral wall of the cervix and vagina. The epoophoron is a homologue to the epididymis in the male.
The histologic terminal segment is the sperm storage region of the epididymis in reptiles, monotremes and both metatherian and eutherian mammals (Figure 1). The testicond epididymis (reptiles and monotremes) has a limited sperm storage capacity compared with the scrotal epididymis (metatherian and eutherian mammals), which has a much larger ...
An acinus (/ ˈ æ s ɪ n ə s /; pl.: acini; adjective, acinar / ˈ æ s ɪ n ər / or acinous) refers to any cluster of cells that resembles a many-lobed "berry", such as a raspberry (acinus is Latin for "berry").
Lactiferous ducts are ducts that converge and form a branched system connecting the nipple to the lobules of the mammary gland.When lactogenesis occurs, under the influence of hormones, the milk is moved to the nipple by the action of smooth muscle contractions along the ductal system to the tip of the nipple.
Terminal end buds (TEBs) are highly proliferative structures at the ends of elongating lactiferous ducts which are involved in development of the mammary glands. [1] TEBs are responsible for the formation of the mammary ductal tree during female puberty .
The genital branch of the genitofemoral nerve, also known as the external spermatic nerve in males, is a nerve in the abdomen that arises from the genitofemoral nerve.The genital branch supplies the cremaster muscle and anterior scrotal skin in males, and the skin of the mons pubis and labia majora in females.
Livy says that Menenius told the soldiers a fable about the parts of the human body and how each has its purpose in the greater function of the body. The rest of the body thought the stomach was getting a free ride so the body decided to stop nourishing the stomach. Soon, the other parts became fatigued and unable to function.
