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 anatomy and physiology of the human ear in this article.
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.
Vestibular system, apparatus of the inner ear involved in balance. It 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.
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.
Human ear - Hearing, Anatomy, Physiology: Hearing is the process by which the ear transforms sound vibrations in the external environment into nerve impulses that are conveyed to the brain, where they are interpreted as sounds.
ear, Organ of hearing and balance. The outer ear directs sound vibrations through the auditory canal to the eardrum, which is stretched across the end of the auditory canal and which transmits sound vibrations to the middle ear.
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.
Ear bone, any of the three tiny bones in the middle ear of all mammals. These are the malleus, or hammer, the incus, or anvil, and the stapes, or stirrup. Together they form a short chain that crosses the middle ear and transmits vibrations caused by sound waves from the eardrum membrane to the.
auricle, in human anatomy, the visible portion of the external ear, and the point of difference between the human ear and that of other mammals. The auricle in humans is almost rudimentary and generally immobile and lies close to the side of the head.
The outer ear directs sound waves from the external environment to the tympanic membrane. The auricle, the visible portion of the outer ear, collects sound waves and, with the concha, the cavity at the entrance to the external auditory canal, helps to funnel sound into the…. Read More.
