What is the external outer ear called?

External or outer ear, consisting of: Pinna or auricle. This is the outside part of the ear.

What is the anatomy of the outer ear?

The medical term for the outer ear is the auricle or pinna. The outer ear is made up of cartilage and skin. There are three different parts to the outer ear; the tragus, helix and the lobule. The ear canal starts at the outer ear and ends at the ear drum.

What is the term used to describe external ears of humans?

External ear: Auricle (pinna), external auditory canal (EAC), and outer surface of tympanic membrane ○

What are the physiology of hearing?

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. …

What is external ear?

The outer ear, external ear, or auris externa is the external part of the ear, which consists of the auricle (also pinna) and the ear canal . It gathers sound energy and focuses it on the eardrum (tympanic membrane).

What is the outer ear?

The outer ear consists of the visible portion on the side of the head, known as the pinna [1], and the external auditory canal (ear canal) [2]. The purpose of the pinna is to catch sound waves, amplify them slightly, and funnel them down the ear canal to the tympanic membrane (eardrum) [3].

What are the external and internal parts of the human ear?

The three sections are known as; the inner ear, the middle ear, the outer ear. The inner ear is made up of the cochlea, the auditory nerve and the brain. The middle ear consists of the middle ear bones called the ossicles (malleus, incus, stapes). The outer ear includes the pinna, the ear canal and the eardrum.

What is the external ear?

What is the physiology of the inner ear?

The inner ear is composed of the sensory organ for hearing—the cochlea, as well as for balance—the vestibular system. The systems are separate, yet both are encased in the same bony capsule and share the same fluid systems. The balance part of the ear is referred to as the vestibular apparatus.

What type of tissue makes up the external ear?

The visible part is called the auricle, also known as the pinna, especially in other animals. It is composed of a thin plate of yellow elastic cartilage, covered with integument, and connected to the surrounding parts by ligaments and muscles; and to the commencement of the ear canal by fibrous tissue.

What is the function of the external ear?

The external ear, which consists of the pinna, concha, and auditory meatus, gathers sound energy and focuses it on the eardrum, or tympanic membrane (Figure 13.3). One consequence of the configuration of the external ear is that it selectively boosts the sound pressure 30- to 100-fold for frequencies around 3 kHz.

What are the major structures of the ear?

The outer ear is composed of three parts, the pinna (or auricle), the auditory canal, and the eardrum (tympanic membrane). What are commonly called ears—the two flaplike structures on either side of the head—are actually the pinnas of the outer ear.

What is the anatomical structure of the ear?

The anatomy of the ear consists of the outer, middle, and inner ear. The shape and form of the outer ear help direct sounds to the eardrum. The middle ear contains the three small bones that pass along the vibrations reaching the eardrum to the inner ear.

What is the physiology of the ear?

Physiology of Ear. Physiology of the Ear is described below: External or Outer Ear: It comprised of Pinna or Auricle. This is the exterior fragment of the Ear. Next to this Peripheral Auditory Canal or Tube is present which attaches the Outer Ear to Middle Ear. After this Tympanic membrane which is also known as Eardrum is present.

What is the outer layer of the ear?

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).
