What are the Auricles of the 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.
Is the auricle part of the external ear?
The auricula. Lateral surface. 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 are the 4 structures of the external ear?
What is the ear?
- External or outer ear, consisting of: Pinna or auricle. This is the outside part of the ear.
- Tympanic membrane (eardrum). The tympanic membrane divides the external ear from the middle ear.
- Middle ear (tympanic cavity) , consisting of: Ossicles.
- Inner ear , consisting of: Cochlea.
What is concha of auricle?
anatomy of human ear …in the auricle, called the concha, leads to the external auditory canal or meatus. The one portion of the auricle that has no cartilage is the lobule—the fleshy lower part of the auricle. acoustic meatus, is called the concha.
What are Auricles and where are they located?
Auricle, also called pinna, 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.
What are Auricles mention their function?
These include the lobule, the concha, the scafoid fossa, and other parts. The ear is the first part of the body to come in contact with auditory stimuli. Sound waves must pass over the auricle before entering the ear canal. Then, the waves pass through the tympanic membrane (eardrum) and into the middle ear.
What is the outer rim of the auricle called?
The bottom portion of the auricle is the lobule, or ear lobe, extending from the lobule is the outer rim of the auricle folds over outwardly, forming the helix. The middle portion of the outer ear, just before the opening into the head, is called the concha because of its bowl-like shape.
What are the 3 functions of the external ear?
The external ear is composed of the pinna and the external auditory meatus. Its principal functions are to collect and funnel sound to the tympanic membrane (eardrum) and to provide cues about the location of wideband sound sources in the vertical plane.
What is in the external 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].
Where is Pinna located?

Where is the Concha located?
nasal cavity
The conchae are located laterally in the nasal cavity and covered by pseudostratified columnar, ciliated respiratory epithelium with a thick, vascular and erectile glandular tissue layer.
Where is the auricle of the ear located?
The auricle is a morphologically unique, highly variable in size and shape structure and a predominant feature of the face. Along with the external acoustic meatus, it constitutes the external ear. The auricle consisted of a cartilaginous skeletal structure that is covered by a cutaneous investor, which conforms to its shape.
What is the anatomy of the outer ear?
Ear Anatomy – Outer Ear. The outer ear comes in all types of shapes and sizes. This structure helps to give each of us our unique appearance. 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. EAR CANAL
Where is the acoustic meatus in the ear?
The external acoustic meatus is an air-filled tubular space that extends from the auricle of the external ear into the temporal bone to the tympanic membrane. What is the function of acoustic meatus?
Which is part of the ear amplifies sound?
The external ear (or outer ear) comprises the auricle (or pinna ), the external auditory meatus, and the tympanic membrane (“eardrum”). The auricle concentrates and amplifies sound waves and funnels them through the outer acoustic pore into the external auditory meatus to the tympanic membrane.
