| Question | Answer |
|---|---|
| SENSANTION | is the process by which our sensory receptors and sense organs. detect and respond to sensory information that stimulates them. |
| PERCEPTION | refers to the process by in which we give meaning to sensory information |
| RECEPTION | is the process of detecting and responding to incoming sensory information. |
| TRANSDUCTION | is the process by which the receptors, change the energy of the detected sensory information into a form which can travel along neural pathways. |
| TRANSMISSION | is the process of sending the sensory Information (as action potentials) relevant areas of the brain via the thalamus |
| INTERPRETATION | is the process in which incoming sensory information is given meaning so that it can be understood. Neural information from the senses is given meaning by the brain. |
| STIMULI | s the external environmental information that provokes a physiologic psychologies activity or response |
| SENSATION | is the process where our sensory organs detect stimuli from the environment and transmit information to the brain. |
| PERCEPTION | is the process where the brain gives meaning (interprets) sensory information. |
| CORNEA | A transparent convex- shaped covering that protects the eye -The cornea helps to focus light mays onto the retina at the back of the eye |
| IRIS | the coloured part of the eye that surrounds the pupil. A ring of muscles that expand or contract to change the size of the pupil, This controls the amount of light that enters the eye |
| LENS | a transparent, flexible structure that is located right behind. the pupil - The lens adjusts is shape according to the distance of the object being viewed. The lens changes Shape by using, the ciliary muscles that are Attached to each end of the lense |
| PUPIL | Black circle in the centre of the eye is an opening in the iris that helps to control the amount of light entering the eye. |
| VITREOUS HUMOUR | a jelly like substance that helps to maintain the shape of the eye and also helps to focus light |
| RETINA | receives and absorbs light and also processes, images. The image focused on the retina is an inverted and reversed image of the object being viewed - When received at the brain it is arranged so that we can perceive it as it is in reality |
| CILIARY MUSCLES | they, expand and contract, enabling the lens to automatically bulge to focus nearby objects onto the retina, and flatten to focus distant objects onto the retina. |
| OPTIC NERVE | carries the visual information from the retina to the primary visual cortex, It exits the eye at the back of the retina |
| PATH OF LIGHT THROUGH THE EYE IN ORDER | Cornea -> Pupil -> Lens -> Retina |
