Episclera
Episclera
Episclera (pronunciation: /ɛpɪˈsklɪərə/) is the thin, loose, highly vascular layer lying between the conjunctiva and the sclera in the eye. It is part of the outermost layer of the eye and plays a crucial role in providing nutrients to the sclera and conjunctiva.
Etymology
The term 'Episclera' is derived from the Greek words 'epi' meaning 'upon' and 'skleros' meaning 'hard'. This refers to the episclera's position on top of the sclera, the white, hard, outer layer of the eye.
Function
The primary function of the episclera is to provide nutrients to the sclera and conjunctiva. It also plays a role in the immune response of the eye, helping to protect it from infection and disease.
