What is the location of elastic cartilage?
Elastic cartilage, fibroelastic cartilage or yellow fibrocartilage is a type of cartilage present in the pinnae (auricles) of the ear giving it shape, provides shape for the lateral region of the external auditory meatus, medial part of the auditory canal Eustachian tube, corniculate and cuneiform laryneal cartilages.
Where is elastic cartilage found and what is its function?
Elastic cartilage , sometimes referred to as yellow fibrocartilage, is a type of cartilage that provides both strength and elasticity to certain parts of the body, such as the ears. Within the outer ear, it provides the skeletal basis of the pinna, as well as the lateral region of the external auditory meatus.
What is the main function of elastic connective tissue?
Elastic fibers are long, thin fibers that form branching network in the extracellular matrix. They help the connective tissue to stretch and recoil.
Is elastic cartilage found in the nose?
Elastic cartilage is present in the ear, nose and parts of the lungs. It is a highly flexible formulation of cartilage. Fibrocartilage is found in the menisci of the knee and the discs of the spine.
What is the function of elastic tissue?
The main components of elastic fibers, elastin and fibrillin-containing microfibrils play a structural and mechanical role in the arteries and their essential function is to provide elasticity and resilience to the tissues.
What is the function of the elastic cartilage?
Elastic cartilage provides support with moderate elasticity. It is found mainly in the larynx, the external part of the ear (pinna), and the tube leading from the middle part of the ear to the throat (eustachian or auditory tube).
Where is elastic connective tissue found in the body?
Elastic connective tissue is dominated by elastin fibers and is found in the parts of the body that need tissue with an ability to stretch, such as the lungs and arteries. Special connective tissue (including cartilage, blood, hemapoetic (blood-producing) tissue, bone and lymphatic tissue).
What is the function of elastic connective tissue?
What is elastic cartilage function?
Elastic cartilage provides strength, and elasticity, and maintains the shape of certain structure such as the external ear. It has a perichondrium.
What is cartilage function?
Cartilage has many functions, including the ability to resist compressive forces, enhance bone resilience, and provide support on bony areas where there is a need for flexibility. The primary cell that makes cartilage is the chondrocyte, which resides within the lacunae.
Where is elastin found in cells?
Elastin is abundant in elastic tissues, and tissues rich in elastin include the aorta and major blood vessels (28–32% dry mass), the lungs (3–7%), elastic ligaments (50%), tendons (4%), and the skin (2–3%) (Uitto, 1979). Elastin and elastic fibers are also found within liver and myocardial tissues.
Where is hyaline cartilage located?
synovial joints
Hyaline cartilage is found in the synovial joints and assists the motion of joints. It is composed of chondrocytes and extracellular matrix. Chondrocytes plays a major role in the organization of extracellular matrix, which is responsible for the biomechanical properties of cartilage tissue.
What is the function of elastin in the skin?
Elastin is a critical skin protein consisting of crosslinked tropoelastin. Elastin combines with microfibrils to form elastic fibers that provide stretch and recoil to the skin.
What is the role of elastin?
Elastin is responsible for resiliency in elastic fibers. As a fibrous protein, it is fundamental to the shape and form of tissue and designed to manage stress. Elastic fibers give vertebrate tissues the ability to distend and recoil, an essential quality for normal homeostatic function.
What is the function of elastic cartilage?
Where is hyaline and elastic cartilage found?
Hyaline – most common, found in the ribs, nose, larynx, trachea. Is a precursor of bone. Fibro- is found in invertebral discs, joint capsules, ligaments. Elastic – is found in the external ear, epiglottis and larynx.
What is the function of the hyaline cartilage?
Where bone ends meet to form a joint, they are covered by hyaline cartilage. This cartilage appears bluish white and glistening in a normal healthy joint. Its primary function is to provide some cushioning and minimize friction between the bone ends.
Is elastic cartilage connective tissue?
Cartilage is a flexible connective tissue of three major types: hyaline cartilage, fibrocartilage and elastic cartilage. Elastic cartilage, also called yellow cartilage, are supporting tissues in an animal’s body. They provide strength and elasticity to the structures they are present in.
