Document Summary
Are those organs and receptors that are associated with touch (sensory receptors) vision, hearing, smell and taste. Sight hearing and smell - distance senses; they bring information from far away. Touch and taste - information which come in contact in. Receive stimuli from the sensory receptors (eye, ear, nose, tongue) and transmit these impulsesto the brain for interpretation. Protected by the orbital socket of the skull, the eyebrows, eyelids and eye lashes. The location of the eye in front of the head allows for superimposition of images from each eye. This enables us to see stereoscopically in three dimensions: length, width and depth. Eyebrows - helps shade the eye and keep perspiration from getting into the eye and causing irritation to the eye. Eye lids and eyes lashes - protect the eye from foreign object. Blinking - lubricates the surface of the eye by spreading tears that are produced by the lacrimal glands.
