CORNEAL CORPUSCLE Meaning and
Definition
-
Corneal corpuscles, also known as Meissner's corpuscles or tactile corpuscles, are specialized nerve endings found within the cornea of the eye. They are responsible for the perception of touch and are considered the primary sensory receptors involved in the tactile sense of the cornea.
These corpuscles are located in the stroma, which is the middle layer of the cornea, and are most densely concentrated in the central region. They consist of encapsulated nerve endings that are elongated and well-suited for detecting changes in pressure and touch stimuli.
Corneal corpuscles play a crucial role in maintaining the sensitivity and protective function of the cornea. They act as mechanoreceptors, converting mechanical stimuli into electrical signals that can be transmitted to the brain for interpretation and response.
When the cornea is exposed to a foreign object or is subjected to injury or irritation, corneal corpuscles are activated, triggering a reflex response such as blinking or tearing. This protective mechanism helps to prevent further damage to the eye.
Corneal corpuscles also contribute to the sensation of touch during routine activities such as blinking, closing of the eyelids, or wearing contact lenses. They enable us to perceive and respond to gentle touches or slight movements on the surface of the eye, enhancing our overall ability to interact with the environment and protect our vision.

Etymology of CORNEAL CORPUSCLE
The word "corneal" is derived from the Late Latin word "corneus", which means "of horn" or "hornlike". This term refers to the cornea, which is the transparent front part of the eye covering the iris and pupil.
The term "corpuscle" comes from the Latin word "corpusculum", meaning "a small body" or "a particle". It is a diminutive form of "corpus", which means "body".
Therefore, the etymology of the term "corneal corpuscle" indicates that it is a small body or particle located in the cornea of the eye.
