The outer ear ends at the eardrum, and the middle ear can be seen in the tympanic cavity behind. The human ear consists of three parts—the outer ear , middle ear and inner ear. The middle ear contains the three small bones—the ossicles —involved in the transmission of sound, and is connected to the throat at the nasopharynx , via the pharyngeal opening of the Eustachian tube. The inner ear contains the otolith organs—the utricle and saccule —and the semicircular canals belonging to the vestibular system , as well as the cochlea of the auditory system. Outer ear The outer ear is the external portion of the ear and includes the fleshy visible pinna also called the auricle , the ear canal, and the outer layer of the eardrum also called the tympanic membrane.

Ear Medically reviewed by Healthline's Medical Network on January 14, The ears are organs that provide two main functions — hearing and balance — that depend on specialized receptors called hair cells. The eardrum vibrates when sound waves enter the ear canal. Ossicles, three tiny bones including the stapes, the smallest bone in the body , pass vibrations to the oval window, which is a membrane at the entrance to the inner ear. Balance is achieved through a combination of the sensory organ in the inner ear, visual input, and information received from receptors in the body, especially around joints.
The ear The ear - a magnificent organ The ear is an advanced and very sensitive organ of the human body. The major task of the ear is to detect, transmit and transduce sound. Another very important function of the ear is to maintain our sense of balance. The best way to describe the functioning of the ear is to describe the path which the sound waves take on their way through the ear.
Maybe the sound you heard was as quiet as your cat licking her paws. Or maybe it was loud, like a siren going by. Sounds are everywhere, and you have two cool parts on your body that let you hear them all: Your ears are in charge of collecting sounds, processing them, and sending sound signals to your brain.
