What is the Exocervix?

The exocervix (or ectocervix) is the outer part of the cervix that can be seen by the doctor during a speculum exam. It is covered in squamous cells.

How is an endocervical curettage performed?

A procedure done after an abnormal Pap test result in which a sample of tissue is scraped from the lining of the cervical canal (the inner part of the cervix that connects the uterus to the vagina) using a spoon-shaped instrument called a curette.

What is the histology of the cervix?

The cervical transformation zone is a dynamic entity formed during puberty and, histologically, is the area where the glandular epithelium is being replaced by squamous epithelium. The junction between the two types of epithelium is the squamo–columnar junction.

What is Squamocolumnar Junction?

The squamocolumnar junction (SCJ) (fig. 5) is defined as the junction between the squamous epithelium and the columnar epithelium. Its location on the cervix is variable. The SCJ is the result of a continuous remodeling process resulting from uterine growth, cervical enlargement and hormonal status.

How do you perform a Culdocentesis?

During a culdocentesis a long thin needle is inserted through the vaginal wall just below the uterus and a sample is taken of the fluid within the abdominal cavity. Culdocentesis is a procedure which checks for abnormal fluid in the space that is just behind the vagina, the posterior cul-de-sac.

How deep is a womans cervix?

3 to 4 inches
When the average woman is unaroused, it’s 3 to 4 inches deep. For someone who has a high cervix, it’s 4 to 5 inches deep. For someone with a lower one, it’s less than 3 inches deep. Keep in mind that the vagina lengthens when aroused.

What is the difference between endocervical curettage and biopsy?

Punch biopsy that uses a device that “punches” out a sample of tissue. Cone biopsy that removes a cone-shaped piece of tissue. Endocervical curettage that uses a spoon-like tool to scrape the lining of the cervical canal.

Is endocervical curettage a biopsy?

Endocervical curettage The cone may include tissue from both the endocervix, as the point of the cone, and the exocervix, as the base. The sample may also include the transformation zone. This type of biopsy is used to remove precancers completely and even treat cancer if it’s in an early stage.

How many layers does a cervix have?

The cervical canal is lined with a single layer of column-shaped cells, while the ectocervix is covered with multiple layers of cells topped with flat cells. The two types of epithelia meet at the squamocolumnar junction….

Anatomical terminology

What are the three parts of the cervix?

Where Is the Cervix?

• The lowest part, which can be seen from inside the vagina during a gynecological exam, is called the ectocervix.
• The highest part is the endocervix, also called the endocervical canal.
• The point in the middle where the endocervix and ectocervix meet is called the transformation zone.

What is the difference between transformation zone and Squamocolumnar Junction?

Transformation zone It corresponds to the area of cervix bound by the original squamocolumnar junction at the distal end and proximally by the furthest extent that squamous metaplasia has occurred as defined by the new squamocolumnar junction (Figures 1.7, 1.13 and 1.14).

Where is the Z line located?

The Z line in the esophagus is the term for a faint zig-zag impression at the gastro-esophageal junction that demarcates the transition between the stratified squamous epithelium in the esophagus and the intestinal epithelium of the gastric cardia (the squamocolumnar junction).

Does Culdocentesis hurt?

Although culdocentesis is generally perceived as quite painful, some practitioners do not use local anesthetics for several reasons. First of all, vaginal mucosa is rather vascular in the posterior fornix. Needle puncture for anesthesia would cause confusing bleeding into the posterior cul de sac.

What is the purpose of Culdocentesis?

Culdocentesis may be used to evaluate females with pain in the lower abdomen/pelvis to determine whether intraabdominal fluid is present and, if present, to reveal the nature of the fluid (eg, serous, purulent, bloody).

Why is an endocervical curettage done?

Why endocervical curettage is done. You may need this procedure if you have abnormal bleeding from your uterus. It can help find out the cause. It may also be done to remove polyps or other reasons for the bleeding.

Does endocervical curettage require anesthesia?

Endocervical curettage (ECC) A tissue sample is scraped from an area just past the opening of the cervix using a curette (small, spoon-shaped instrument) or a thin, soft brush. This can be done in your gynecologist’s office and does not require anesthesia.

Is endocervical curettage painful?

A large number of patients with abnormal cervical cytology undergo subsequent colposcopy-directed punch biopsy (punch biopsy) and endocervical curettage (ECC). These procedures are painful, which may cause uncomfortable after effects and evoke fear of follow-up care if not adequately managed.

How far deep is a woman’s cervix?

When the average woman is unaroused, it’s 3 to 4 inches deep. For someone who has a high cervix, it’s 4 to 5 inches deep. For someone with a lower one, it’s less than 3 inches deep. Keep in mind that the vagina lengthens when aroused.

How big is a woman’s cervix?

The cervix makes up the lower third of the uterus and connects to the vaginal canal. It isn’t very large, only about 3-5 centimeters thick and 2-3 centimeters across.

What is the histology of the endocervix?

Histology of the Normal Endocervix. The uterus, an inverted triangular shaped muscular organ with a central mucosal lined cavity, is divided into regions: the fundus, the corpus, the isthmus or lower uterine segment, and the endocervical canal and the exocervix (Fig. 3.1).

What are the job opportunities for histology technicians?

Job openings for medical and clinical lab technicians, including histology technicians, are expected to increase faster than average according to the Bureau of Labor Statistics. With an aging population, there is a greater need to diagnose medical conditions through lab procedures.

What type of epithelium covers the exocervix?

The exocervix is covered by non-cornified stratified squamous epithelium identical to the squamous epithelium covering the vagina (Fig. 3.2 ).

Where can I study histology at the Mayo Clinic?

Students are taught by Mayo Clinic’s histology teaching faculty in laboratories specifically designed for training students. Although graduates are fully prepared to work in any histology laboratory, many graduates go on to work at one of the Mayo Clinic’s three national campuses in Phoenix/Scottsdale, AZ, Jacksonville, FL, and Rochester, NY.
