Testes

Penis

• There are two testes, located on the outside of the body within sac like structures called a scrotum, within the pelvic region, posterior to the penis and anterior to the anus. (David, 2014)
• The testes each weigh about 25 grams; they are 4 – 5cm in length and 2 – 3 cm in width.(David, 2014)
• The testes are covered by a fibrous capsule called tunica Albuginea (David, 2014).
• The Tunica is divided by fibrous tissues to form web shaped lobes. Each lobe is 3 to 10 coiled tubules called seminiferous tubules surrounded by connective tissue. (David, 2014)

• The penis has three parts: the root which is attached to the wall of the abdomen, the body or shaft and the glans. The glans is the head of the penis which is covered by a loose layer of skin called the foreskin.
The opening of the urethra is at the tip of the glans and is contained in the corpus spongiosum.
• The penis contains a number of sensitive nerve endings, lymphatic and blood vessels, also two suspensory ligaments made up of elastic fibers.
• The body of the penis is cylindrical in shape and consist of three internal chambers the corpus spongiosum,
• All three chambers are made up of sponge like erectile tissues called corpus cavernosa. They contain large spaces which fill with blood; the skin is loose and elastic.
• The erectile tissues are in tinny pools of blood vessels called cavernous sinuses.
• Each of these muscles are surrounded by smooth muscles and supported by elastic fibrous tissues, made up of protein called collagen.

...layers have longitudinal fibers. These fiber endings are called fimbriae.(The Editors of Encyclopedia Britannica, 2014)

The Uterus
• The uterus is a thick muscular organ located medial with abdomen. In an adult female the uterus is 7.5 cm long 5 cm wide and 2.5 cm thick before pregnancy. (Dr.Barbara,2014 )
• The more slender part of the uterus known as the cervix. The anterior part of the uterus body is known as the corpus uteri. This more circular. (Dr.Barbara,2014 )
• The uterus consists of three layers: the Myometrium, which forms most of the uterus muscular very firm and consist of densely packed unstripped smooth muscle fibers. The serous membrane , the outer layer which covers most of the uterus, then folds back to form the uterus ligament on each side. The endometrium the inner most membrane that lines the uterine cavity of the uterus. (Dr.Barbara,2014 )
