Do You Hear What I Hear?
3 parts of the ear Outer n Middle n Inner n
Outer Ear n n n Pinna (auricle) – visible part of the ear (function is to collect sound waves) External auditory cannal – ear canal Tympanic Membrane – ear drum and it separates the outer and middle ear
Cerumen n Cerumen – ear wax n Function – is to protect the ear
Middle Ear n A. n Cavity in the temporal bone Connects with the pharynx by the Eustachian tube – which equilizes pressure in the middle ear with the outside atmosphere
Middle Ear n Contains the 3 smallest bones in the body which transmit sound waves to the inner ear: u Malleus (Hammer) u Incus (Anvil) u Stapes (Stirrup)
Inner Ear n n Contains the cochlea – Spiral – shaped organ of hearing Cochlea contains a membraneous tube, the cochlea duct, which is filled with fluid that vibrates when sound waves are transmitted by the stapes n
Inner Ear n Organ of Corti – delicate hair-like cells that pick up vibrations of fluid and transmit them as a sensory impulse along the auditory nerve to the brain
Inner Ear Semicircular Canals – three structures in inner ear that contain liquid set in motion by head and body movements n Impulses are sent back to the cerebellum to help maintain body balance (equilibrium) n
Pathway of Hearing External auditory canal Tympanic membrane incus, and stapes) Auditory nerve Ossicles (malleus, cochlea
The Nose n Smell accounts for 90% of taste n Tissue in the nose (olfactory epithelium) contains specialized nerve cell receptors n Those receptors stimulate the OLFACTORY NERVE to send to brain
The Tongue n Mass of muscle tissue n Bumps on the surface are PAPILLAE, they contain the taste buds n Receptors in taste buds send stimuli through 3 cranial nerves to the cerebral cortex
