Eyes, Ears & Mouth

As a sensory organ, the eye's role is to detect light, which enables us to see. The integrity of the retina is therefore crucial, as it contains light-sensitive cells, cones and rods, along with the optic nerve pathways. Intact, well functioning retinas ensure that signals reliably reach the brain's visual center, where they are translated into visual perceptions.

The oral cavity is the beginning of the human digestive tract and contains the structures required for chewing and speaking, such as jaw bones and muscles, teeth, tongue and salivary glands. Healthy bones, teeth and mucous membranes depend on a good supply of nutrients.

The ear is made up of the outer, middle and inner ear and the auditory nerve, which is responsible for processing sound waves and converting them into acoustic perception via the brain, presenting to us as sound.
