• what makes the ear?

  The ear is the organ through which we detect the sound stimuli, and the sense of balance.
• name the parts of the ear

  pinna,ear canal, eardrum, auditory ossicles, eustachian tube, cochlea, and the auditory nerve.
• how does hearing work?

  The sound waves reach the eardrum, it vibrates. Then the auditory ossicles move, and they transmit the stimulus to the cochlea. Inside the cochlea, hair cells. Are mechanoreceptors, transform vibrations into nerve impulses. Reach the hair cells, through a fluid, endolymph, floods the interior of the cochlea. Sound of stimuli transform into a nerve impulse. Auditory nerve to the brain.
• how does our sense of balance work?

  Inner ear recognises the position we are in. • Semicircular ducts, the utricle and the saccule, contain hair cells and endolymph, information about posture and movement. • We move our head, endolymph moves, hair cells. Send information to the brain about the new position.
• name the parts involved in the sense of balance


  ears (hearing), eyes (sight) and proprioceptors
• name the preventive measures of the ear

  Avoid noisy places. Damage eardrum/auditory ossicles, loss of hearing. • Clean your ears properly. • Moderate the volume of your headphones.
