Surrounding all stages of the developing sperm cells are elongate, branchingSertoli cells. Sertoli cells are a type of supporting cell called a sustentacular cell, or sustenocyte, that are typically found in epithelial tissue. Sertoli cells secrete signaling molecules that promote sperm production and...
motile projectiles. They are small cells that consist of a head region, midpiece region, and tail region. The head region contains a cap-like covering called an acrosome. The acrosome contains enzymes that help the sperm cell penetrate the outer membrane of an ...
ovary and to theuterusUterusThe uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The uterus has a thick wall made of smooth muscle (the myometrium) and an inner mucosal layer (the endometrium). The most inferior portion of the uterus is the cervix, ...
The uterus is the central anatomical landmark of the female internal genitals and pelvic anatomy. It is a highly muscular, childbearing organ in females, approximating 3 x 2 x 1 inches in size in a nulliparous. Even though the uterus is primarily a pelvic organ, but during later stages of ...

Overall brain size doesn't correlate with level of intelligence for non-human animals. For instance, the brain of a sperm whale is more than five times heavier than the human brain, but humans are considered to be of higher intelligence than sperm whales. A more accurate measure of an anima...
the ampullary portion, where sperm have collected by migrating “upstream” against the current. This opening is of considerable clinical importance as blood, ascending infections, or pus can pass out of the tube to invade the abdominal cavity, with resultant pain, endometriosis, or ...
Male gametes are called sperm, and are the smallest human cells that are equipped with a tail-like structure named the flagellum to aid in motility to reach the female gamete. The female gamete is the ovum, and is the largest human cell that is ovulated in the female reproductive system. ...
Female condom –A flexible, thin plastic pouch that prevents sperm from entering the uterus. A portion of the condom is put into the vagina before intercourse. The uterus, often known as the womb, is where the baby develops during pregnancy. Female condoms can also aid in the prevention of...
in length, but this varies from person to person. The fallopian tubes' main function is to pick up an ovulated egg from the ovary. The fallopian tubes serve as the site of fertilization, where sperm fuses with the egg to form a zygote. The fallopian tubes are divided into 4 main ...
