Conjunctiva Histology and contour - Essay Example(Blue Histology the optic)There are slight histological distinctions in the conjunctiva portions. The conjunctiva covering the lid moulding and bulbar conjunctiva is a modified nonkeratinized, stratified squamous epithelium. The tarsal and fornix conjunctiva is covered by stratified squamous and cuboidal to columnar epithelium of diverse thickness which carry through some squamoidal characteristics, such as having numerous desmosomes and a microvillus surface. Goblet cells are profuse in the tarsus, fornix, and specialized areas as the plica semilunaris, while they are scrimp nearby the lid boundary and the corneas limbus.A histological sagittal section of both eyelids and the eye are shown here (1) cornea (2) lens (3) fornix part of the conjunctiva. (4) peripheral conjunctiva (5) palpebral portion of the lacrimal gland (6) tarsal conjunctiva. The constitution of Goblet cells within the epithelium at each of these regions is fluc tuant.
