Document Summary

Executive level: neuro-motor instructions sent to effector level. Effector level: body part used to be successful in system goal. Environment: observable action: return to reference mechanism making comparison to original instructions make corrections if necessary. Extrageniculate pathway: visual information sent to retina, sent to superior colliculus, sent to pulvinar (in thalamus, sent to ppc (bypasses v1) Solely processes for controlling/monitoring movement: unconsciously controlled. Cornea: transparent part on front of eye providing optical power by refracting light. Iris: coloured part controlling light levels (like camera aperture) Pupil: opening in centre of eye directly determining light level entering eye. Ciliary muscle: allow lens to shape and thus focus near or far images. Retina: photoreceptive layer at back of eye converting light into electrical energy. Fovea: centre part of retina with highest concentration of cones. Optic nerve: transmits electrical impulses from retina to brain. Optic disc (blind spot): connection point between retina and optic nerve.
