Organ Histology of "Eye" - Mulligan

Page history last edited by Amber Mulligan 4 years, 2 months ago

The external structures of the eye include:

  • Conjunctiva
  • Tear film
  • Accessory glands
  • Muscles: Orbicularis oculi, levator palpebrae superioris, superior tarsal muscle
  • Eyelid

The internal structures of the eye include: 

  • Outermost Layers: Sclera and Cornea
  • Middle Layer: Uvea (Iris, Ciliary Body, Choroid)
  • Innermost layer: Lens, Vitreous, Retina

The functions of the external eye structures is to protect the internal eye. 

The eyelid prevents objects from entering the inner eye and helps refresh and distribute the tear film by blinking. Eyelashes are finely sensitive to touch and warn the eye of possible debris and particles that may cause injury. The primary functions of the internal parts of the eye are structural and visual functions.
