Detailed explanation-1: -The corneal reflex causes both eyes to blink in response to tactile stimulation of the cornea.
Detailed explanation-2: -Contact with the cornea initiates 2 reflexes: blink reflex (corneal reflex) and tear production. The corneal blink reflex is caused by a loop between the trigeminal sensory nerves and the facial motor (VII) nerve innervation of the orbicularis oculi muscles.
Detailed explanation-3: -Reflexes include not only such simple acts as chewing, swallowing, blinking, the knee jerk, and the scratch reflex, but also stepping, standing, and mating.
Detailed explanation-4: -The corneal reflex, also known as the blink reflex or eyelid reflex, is an involuntary blinking of the eyelids elicited by stimulation of the cornea (such as by touching or by a foreign body), though it could result from any peripheral stimulus.
Detailed explanation-5: -During accommodation three motor responses occur: convergence (medial rectus contracts to direct the eye nasally), pupil constriction (iris sphincter contracts to decrease the iris aperture) and lens accommodation (ciliary muscles contract to decrease tension on the zonules).
