  2. Colposcopy - Wikipedia

    en.wikipedia.org/wiki/Colposcopy

    Colposcope Transformation zone types: [11] Type 1: Completely ectocervical (common under hormonal influence). Type 2: Endocervical component but fully visible (common before puberty). Type 3: Endocervical component, not fully visible (common after menopause). During the initial evaluation, a medical history is obtained.

    en.wikipedia.org/wiki/Loop_electrical_excision...

    The cervical transformation zone and lesion are excised to an adequate depth, which in most cases is at least 8 mm, and extending 4 to 5 mm beyond the lesion. A second pass with a more narrow loop can also be done to obtain an endocervical specimen for further histologic evaluation.

  4. Cervical ectropion - Wikipedia

    en.wikipedia.org/wiki/Cervical_ectropion

    The squamocolumnar junction, where the columnar secretory epithelium of the endocervical canal meets the stratified squamous covering of the ectocervix, is located at the external os before puberty. As estrogen levels rise during puberty, the cervical os opens, exposing the endocervical columnar epithelium onto the ectocervix. This area of ...

  5. Pap test - Wikipedia

    en.wikipedia.org/wiki/Pap_test

    Transformation zone types, determining the Pap test location: [66] Type 1: Completely ectocervical. Type 2: Endocervical component but fully visible. Type 3: Endocervical component, not fully visible. Cervix in relation to upper part of vagina and posterior portion of uterus. Squamous metaplasia of the cervix, with typical features. Pap stain.

  6. Cervical canal - Wikipedia

    en.wikipedia.org/wiki/Cervical_canal

    The cervical canal is generally lined by "endocervical mucosa" which consists of a single layer of mucinous columnar epithelium. However, after menopause, the functional squamocolumnar junction moves into the cervical canal, and hence the distal part of the cervical canal may be lined by stratified squamous epithelium (conforming to a "type 3 transformation zone").

  8. Cervix - Wikipedia

    en.wikipedia.org/wiki/Cervix

    Type 3: Endocervical component, not fully visible (common after menopause). In prepubertal girls, the functional squamocolumnar junction is present just within the cervical canal. [ 17 ] : 411 Upon entering puberty, due to hormonal influence, and during pregnancy, the columnar epithelium extends outward over the ectocervix as the cervix everts.

  9. Compartment syndrome - Wikipedia

    en.wikipedia.org/wiki/Compartment_syndrome

    ACS is defined as a critical pressure increase within a confined compartmental space causing a decline in the perfusion pressure to the tissue within that compartment . [5] A normal human body needs a pressure gradient for blood flow. [43] It must go from the higher-pressure arterial system to the lower-pressure venous system.
