Nov 21, 2024 · Human ear, organ of hearing and equilibrium that detects and analyzes sound by transduction and maintains the sense of balance. Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear. Learn about the …

Human ear - Anatomy, Hearing, Balance: The most-striking differences between the human ear and the ears of other mammals are in the structure of the outermost part, the auricle. In humans the auricle is an almost rudimentary, usually immobile shell that lies close to the side of the head.

Feb 12, 2025 · The human ear is most sensitive to and most easily detects frequencies of 1,000 to 4,000 hertz, but at least for normal young ears the entire audible range of sounds extends from about 20 to 20,000 hertz.

There are actually two labyrinths of the inner ear, one inside the other, the membranous labyrinth contained within the bony labyrinth. The bony labyrinth consists of a central chamber called the vestibule, the three semicircular canals, and the spirally coiled cochlea.

Humans have two ears, one on each side of the head. Each ear has three sections: the outer ear, the middle ear, and the inner ear. The outer ear is divided into two main parts: the auricle and the ear canal. The auricle is the part of the ear that is visible on the sides of the head. It is made of a tough material called cartilage.

Inner ear, part of the ear that contains organs of the senses of hearing and equilibrium. The bony labyrinth, a cavity in the temporal bone, is divided into three sections: the vestibule, the semicircular canals, and the cochlea.

Structures of the human ear. The cartilaginous auricle and the auditory canal of the outer ear direct sound waves to the middle ear. The eardrum, stretched across the end of the canal, vibrates as sound waves reach it.

The ear can distinguish different subjective aspects of a sound, such as its loudness and pitch, by detecting and analyzing different physical characteristics of the waves.

vestibular system, apparatus of the inner ear involved in balance. The vestibular system consists of two structures of the bony labyrinth of the inner ear, the vestibule and the semicircular canals, and the structures of the membranous labyrinth contained within them.

Within the bony labyrinth is a membranous labyrinth, which is also divided into three parts: the semicircular ducts; two saclike structures, the saccule and utricle, located in the vestibule; and the cochlear duct, which is the only part of the inner ear involved in hearing.
