Fimbriae Fimbriae. The fimbriae of the uterine tube, also known as fimbriae tubae, are small, fingerlike projections at the end of the fallopian tubes, through which eggs move from the ovaries to the uterus. The fimbriae are connected to the ovary. Small epithelial cells — those that line cavities throughout the body — with small, slender cilia (microscopic, hair-like structures) pulsate inside the fallopian tubes to guide the ovum, or egg, from the ovary to the uterus.

What is Frenuloplasty? Many men undergo a frenuloplasty when intercourse becomes painful due to the restricted movement of the foreskin. The frenulum tissue connects the foreskin to the vernal mucosa and aids in the retraction of the foreskin when the penis is erect.A frenuloplasty can correct this abnormal restriction of the foreskin while preventing the need for a circumcision. The penile frenuloplasty is performed on an outpatient basis.renulum tissue is designed to secure the mobility of the organ or muscle involved. When the frenulum is too small, it causes the movement to be restricted. Frenuloplasty can help clear up childhood speech problems, infant feeding difficulties, and relieve the pain of intercourse that some men experience.

The Cerebrum The posterior (back) portion of the corpus callosum is called the splenium; the anterior (front) is called the genu (or knee); between the two is the truncus, or body, of the corpus callosum.he corpus callosum (/ˈkɔrpəs kəˈloʊsəm/ ; Latin for tough body), also known as the callosal commissure, is a wide, flat bundle of neural fibers about 10 cm long beneath the cortex in the eutherian brain at the longitudinal fissure.

What Is A Frenectomy? Frenectomy is a scary sounding word for a fairly simple and common procedure that addresses a few different medical problems, usually in the mouth and in children. The word frenum, or frenulum, describes the tough tissue that attaches any organ to the its neighboring tissue to prevent it from moving too much.ypes of Frenectomy. Labial Frenectomy (upper lip): A labial frenectomy most often involves the frenum attaching the upper lip to the upper jaw, usually in children as their teeth and gums develop. The problem of the upper labial frenum is primarily one of aesthetics, but not necessarily.

- The purpose of the foreskin is to protect the glans of the penis from chafing and other kinds of damage. Part of the foreskin that is usually removed or substantially reduced … during circumcision is called the frenulum, or frenum.

Tenaculum For the anatomical structure, see Tenaculum (anatomical structure). A tenaculum is a surgical instrument, usually classified as a type of forceps. It consists of a slender sharp-pointed hook attached to a handle and is used mainly in surgery for seizing and holding parts, such as blood vessels. Uses include:

Frenectomy Not to be confused with Phrenectomy, removal of the phrenic nerve. A frenectomy (also known as a frenulectomy, frenulotomy or frenotomy) is the removal of a frenulum, a small fold of tissue that prevents an organ in the body from moving too far. It can refer to frenula in several places on the human body. It is related to frenuloplasty, a surgical alteration in a frenulum.

Diverticulum A diverticulum (plural: diverticula) is the medical or biological term for an outpouching of a hollow (or a fluid-filled) structure in the body. Depending upon which layers of the structure are involved, they are described as being either true or false. Bladder diverticulum: Balloon-like growths on the bladder commonly associated with a chronic outflow obstruction, such as benign prostatic hyperplasia in older males. 2  Usually found in pairs on opposite sides of the bladder, bladder diverticula are often surgically removed to prevent infection, rupture, or even cancer.

- The frenulum is like the joining ridge under the tongue. It is the small sheet of skin underneath the glans (head) of the penis, which joins the glans to the foreskin. If the frenulum is too short on the erect penis, it does not allow the foreskin to slide forward and causes pain.During intercourse, this can happen and as a result the tight frenulum will often rip and bleed.In the event, immediate pressure must be applied to the area and urgent medical attention is required.n incision is made around the glans of penis (similar to circumcision) and the skin of the shaft of the penis is pulled down. The curvature areas are identified and multiple plication stitches are placed on the opposite side of the curvature. This acts as counter traction to pull the penis straight.
