Epithelia are classified according to the number of cell layers

Epithelia are strengthened by connective tissue fibres between epithelial cells

Epithelia are separated from underlying connective tissue by a basal lamina

Epithelia are classified according to the shape of the outermost cell layer

Only stratified epithelia contain two or more rows of cell nuclei

Are endocrine glands

Are classified as connective tissue

Feature holocrine secretion

Feature slow cell turnover

Are modified sweat glands

Stratified cuboidal

Simple columnar

Simple squamous

Pseudostratified columnar

Keratinised stratified squamous

Osteoblasts

Osteoclasts

Fibroblasts

Fibrocytes

Osteocytes

Is composed of proteoglycans

Is produced by elastoplasts

Can be seen in the light microscope with H&E staining

Has high tensile strength

Allows tissues to stretch and contract

Parasagittal

Ventromedial

Superomarginal

Posterolateral

Craniocaudal

Sits on top of an acellular basal lamina

Contains many goblet cells

Is a keratinised stratified columnar epithelium

Contains nerve endings

Tendons contain substantial amounts of collagen fibres

Tendons are a form of dense irregular connective tissue

Tendons contain substantial amounts of microtubules

Tendons are avascular

Tendons contain substantial amounts of elastic fibres

Are involved in maintenance of the blood-retinal barrier

Are found only between epithelial (incl. endothelial) cells

Are continuous belts of interlocking junctional proteins around the circumference of epithelial cells

Control the permeability of epithelia

Allow the movent of ions and small molecules between adjoining cells

Is found in ligaments

Is found in the dermis of the skin Correct

Contains fibroblasts

Resists stretch in a single plane

Is found in tendons
