Give the reflex pathway of eye closing suddely of bright light
Answers
Reflexes are an essential part of protective and homeostatic function, both in general terms and with specific reference to ocular structures. A wide range of stimuli and responses, with varying degrees of central processing, is involved in such reflexes. The simplest reflexes are monosynaptic, such as the stretch or myotatic reflex. More complex polysynaptic reflexes are involved in many regula- tory and protective functions - these include auto- nomic as well as somatic reflexes. Ocular auto- nomic reflexes include the oculocardiac, pupillary, accommodative and lacrimatory reflexes. Ocular somatic reflexes include eyelid and extra-ocular muscle reflexes (such as Bell’s phenomenon, vestibulo-ocular and optokinetic reflexes)
