H&E stain of biopsy of normal esophagus showing the stratified squamous cell epithelium

Section of the human esophagus. Moderately magnified. The section is transverse and from near the middle of the gullet.
a. Fibrous covering.
b. Divided fibers of longitudinal muscular coat.
c. Transverse muscular fibers.
d. Submucous or areolar layer.
e. Muscularis mucosae.
f. Mucous membrane, with vessels and part of a lymphoid nodule.
g. Stratified epithelial lining.
h. Mucous gland.
i. Gland duct.
m’. Striated muscular fibers cut across.

Vertical section of human cornea from near the margin.

In stratified squamous epitheli the cells which line the epithelium are arranged in layers and as such some of them won't be in contact with the basement membrane, an example of which can be found in human skin^{[citation needed]}. A biopsy (in Greek: bios = life and opsy = look/appearance) is a medical test involving the removal of cells or tissues for examination. ... The esophagus (also spelled oesophagus/Å“sophagus), or gullet is the muscular tube in vertebrates through which ingested food passes from the mouth area to the stomach. ... Squamous cells are basically types of cells which can be identified histologically by the fact that they look flattened and thin under a microscope. ... In zootomy, epithelium is a tissue composed of a layer of cells. ... Section of mucous membrane of human rectum. ... The mucous membranes (or mucosae; singular: mucosa) are linings of ectodermic origin, covered in epithelium, and are involved in absorption and secretion. ...

Stratified squamous epithelium is further classified by the presence or absense of keratin at the apical surface. Microscopy of keratin filaments inside cells. ... Apical, from the Latin apex (plural apices) meaning to be at the apex or tip, may refer to: An apical consonant, a consonant produced with the tip of the tongue Apical dominance An apical bud An apical pulse: apical pulse is your heart rate when counted with a stethoscope (steth...

• Non-keratinized stratified squamous epithelium: cornea, esophagus, and vagina
• Keratinized stratified squamous epithelium: skin, tongue (specifically, tongue is "parakeratined", or partially keratinized)

The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber, providing most of an eyes optical power [1]. Together with the lens, the cornea refracts light and, as a result, helps the eye to focus. ... The esophagus (also spelled oesophagus/Å“sophagus), or gullet is the muscular tube in vertebrates through which ingested food passes from the mouth area to the stomach. ... The vagina, (from Latin, literally sheath or scabbard ) is the tubular tract leading from the uterus to the exterior of the body in female placental mammals and marsupials, or to the cloaca in female birds, monotremes, and some reptiles. ... For alternate meanings see skin (disambiguation). ... Tongue The tongue is the large bundle of muscles on the floor of the mouth that manipulates food for chewing and swallowing. ...
