Tender Outer Ear (Auricle) and Causes of Pain Anatomy of the Auricle. The auricle or pinna is a relatively large appendage on the side of the head. It is prominent in most people and plays a very important role in hearing – it directs sound waves into the ear canal. The auricle is composed of cartilage which is covered by skin.

Thyroid cartilage The thyroid cartilage is the largest of the nine cartilages that make up the laryngeal skeleton, the cartilage structure in and around the trachea that contains the larynx.he cartilage is composed of two halves, which meet in the middle at a peak called the laryngeal prominence, also called the Adam's apple. In the midline above the prominence is the superior thyroid notch. A counterpart notch at the bottom of the cartilage is called the inferior thyroid notch.

The Outer Ear Parts of the Ear: Outer Ear | Middle Ear | Inner Ear. The outer ear consists of the pinna, or auricle, and the ear canal (external auditory meatus). The pinna – the part of the ear that we see on each side of our heads – is made of cartilage and soft tissue so that it keeps a particular shape but is also flexible.The pinna serves as a collector of sound vibrations around us and guides the vibrations into the ear canal.he pinna – the part of the ear that we see on each side of our heads – is made of cartilage and soft tissue so that it keeps a particular shape but is also flexible.

- If the remaining skin cannot cover the cartilage, the cartilage should be cut away from the wound margin to allow overlying skin closure. In the case of a linear laceration to the pinna in which the skin does not approximate, a wedge excision technique may be used. See the image below. Wound that requires a wedge excision. To perform a wedge excision, a No. 15 scalpel is used to cut a full thickness triangle from the antihelix. See the image below.

Definitions &Translations Cartilage /ˈkɑrtɨlɨdʒ/ is a flexible connective tissue in animals, including the joints between bones, the rib cage, the ear, the nose, the bronchial tubes and the intervertebral discs. It is not as hard and rigid as bone, but it is stiffer and less flexible than muscle.artilage is classified in three types, elastic cartilage, hyaline cartilage and fibrocartilage, which differ in relative amounts of cartilage. Chondroblasts that get caught in the matrix are called chondrocytes. Cartilage does not contain blood vessels (avascular) or nerves (aneural).

- The hip is a ball-and-socket joint. The socket (called the acetabulum) is part of the pelvis. The ball (called the femoral head) is attached to the upper end of the thigh bone, and rests inside the socket.The labral cartilage structure surrounds the opening of the hip socket and joins seamlessly to the articular cartilage lining the hip socket.or the hip to last a lifetime, the ball and socket and cartilage structures all must work together like a well-oiled machine. When abnormal contact occurs between the ball of the hip and the rim of the hip socket, this condition is called femoral acetabular impingement or hip impingement.

- Cartilage is sometimes suggested for the following health conditions: Psoriasis. Preliminary studies suggest that extracts of shark cartilage may reduce inflammation and itching from psoriasis. Psoriasis is a skin disorder that shows up as raised, reddish-pink areas covered with silvery scales and red borders.

- Cartilage. Cartilage is type of dense connective tissue. Cartilage is composed of cells called chondrocytes which are dispersed in a firm gel-like ground substance, called the matrix. Cartilage contains no blood vessels and nutrients are diffused through the matrix.hondrocytes are the only cells found in cartilage. They are responsible for the secretion and maintenance of the matrix. The matrix immediately surrounding the chondrocytes is referred to as the territorial matrix and stains darker than the interstitial matrix. Chondrocytes lie in a cavity called a lacuna.

- This slide shows a stained section of the trachea (windpipe). Note the rings of hyaline cartilage embedded in the walls of the trachea that provide support and help to maintain an open airway. Hyaline cartilage is the most common form of cartilage in the body, making up part of the nose, connecting ribs to the sternum and covering the articulating surfaces of bones. When sectioned and stained, the matrix of hyaline cartilage takes on a light purple color.

- A cartilaginous joint is a joint where cartilage connects the bones. Cartilage is a tough but flexible connective tissue that comes in three types: hyaline (also called articular), elastic and fibrocartilage. Unlike the more common synovial joints, cartilaginous joints do not have a space (joint cavity) between the bones.

1d. 1. The External Ear The cartilage of the auricula (cartilago auriculæ; cartilage of the pinna) (Figs. 905, 906) consists of a single piece; it gives form to this part of the ear, and upon its surface are found the eminences and depressions above described. It is absent from the lobule; it is deficient, also, between the tragus and beginning of the helix, the gap being filled up by dense fibrous tissue.

How is cartilage related to neck and back pain? Sections. Cartilage is connective tissue located between bones. It provides a cushion in joints and gives structure to many parts of the body, including the ears and nose. It also forms intervertebral discs, the “shock absorbers” between the vertebrae that help give the spine cushioning and flexibility. Cartilage cells are called chondrocytes. These cells produce the collagen that gives the cartilage structure, along with water and a glycoprotein called proteoglycan. There are three types of cartilage, distinguishable by the amount of collagen and other proteins located within the cartilage cells:

Tracheal cartilages In the trachea, or windpipe, there are tracheal rings, also known as tracheal cartilages. Cartilage is strong but flexible tissue.The tracheal cartilages help support the trachea while still allowing it to move and flex during breathing.he tracheal cartilages have an order, starting with the peculiar tracheal cartilages. These are the first and last rings in the trachea. The first cartilage is broad and divided at the end. It sometimes blends in with the following cartilage, depending on the structure of the trachea.

Getting A Cartilage Piercing? Know This First! Anti-helix: This area is the raised ridge between the helix and ear canal. It involves rook, which is the upper ridge and snug, the lower ridge of the helix. Rook / Anti – Helix Piercing: Snug: The lower portion of the anti-helix. In this case, the cartilage is pierced from end to the other instead from front to back.

Auricle The auricle is also known as the pinna, and it is most commonly referred to as the ear. It is the most obviously visible part of the auditory system. An auricle consists of skin over contoured cartilage, and it is held in place by muscles and ligaments.uricles are located on both sides of the head, near the temple and where the jaw meets the skull. Each ear is subdivided into the several regions. 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.

Antitragus In humans, it is a small tubercle on the visible part of the ear; the pinna. The antitragus is located just above the earlobe and points anteriorly. It is separated from the tragus by the intertragic notch. The antitragicus muscle, an intrinsic muscle of the ear, arises from the outer part of the antitragus.
