The adult skeleton is made up of various bones and cartilages, which are tissues made up of cells surrounded by a matrix of fibers. Cartilages are found in various parts of the body, including the joints, the respiratory system, and the ear. In this essay, we will focus on the major cartilages of the adult skeleton.

One of the most well-known cartilages in the body is the hyaline cartilage, which is a type of connective tissue found in many parts of the body. It is composed of cells called chondrocytes that are embedded in a matrix made up of collagen and elastin fibers. The hyaline cartilage is smooth and glossy in appearance, and it is found in several areas of the body, including the ends of the long bones, the ribs, the larynx, and the trachea.

Another important cartilage in the adult skeleton is the fibrocartilage, which is a type of connective tissue that is composed of chondrocytes and a matrix made up of collagen fibers. Fibrocartilage is found in areas of the body that experience a lot of mechanical stress, such as the intervertebral discs, the pubic symphysis, and the menisci of the knee. It is also found in the tendons and ligaments, which are connective tissues that attach bones to each other and help to support and stabilize the joints.

Another major cartilage in the adult skeleton is the elastic cartilage, which is composed of chondrocytes and a matrix made up of elastic fibers. Elastic cartilage is found in several parts of the body, including the external ear, the epiglottis, and the larynx. It is responsible for maintaining the shape and structure of these structures, and it is also able to withstand a great deal of stretching and bending.

In addition to these cartilages, the adult skeleton also contains several other types of connective tissues, including bone, fat, and blood. These tissues play important roles in the structure and function of the skeleton, and they work together to support and protect the body.

In conclusion, the adult skeleton is made up of several major cartilages, including the hyaline cartilage, the fibrocartilage, and the elastic cartilage. These cartilages are found in various parts of the body and play important roles in maintaining the structure and function of the skeleton.

6.2A: Structure, Type, and Location of Cartilage

The adult vertebral column consists of 24 vertebrae plus the sacrum and coccyx. The posterior border of each sheet project superiorly and inferiorly to form the superior and inferior horns also known as cornu. . The bones of the skeleton also serve as the primary storage site for important minerals such as calcium and phosphate. Their chondrocytes are spherical, and the only fiber type in their matrix is fine collagen fibers. The larynx voice box is an organ located in the anterior neck.

Compare and contrast the structure of the four bone classes and provide examples of each class. Indicate the locations and functions of red and yellow marrow, articular cartilage, periosteum, and endosteum. Finally, the red marrow cavities of bones provide a site for hematopoiesis blood cell formation. The skeleton is subdivided into two parts. Finally the menisci are in the middle of the cartilage and those that the shock absorbers.

Cartilage consists primarily of water, which accounts for its resilience, that is, its ability to spring back to its original shape after being compressed. When the epiphyseal plate closes, it is replaced by bone. The cricoid is the only complete circle of cartilage in the larynx or trachea. Chapter Review The skeletal system includes all of the bones, cartilages, and ligaments of the body. Hyaline Cartilages Hyaline cartilages, which look like frosted glass when freshly exposed, provide support with flexibility and resilience. The cartilages that support the respiratory tubes and larynx are drawn separately on the right. They articulate with the apices of the arytenoid cartilages.

They consist of translucent protoplasm in which fine interlacing filaments and minute granules are sometimes present. Key Terms chondroitin sulfate: An important structural component of cartilage that provides much of its resistance to compression. The remodeling of cartilage is predominantly affected by changes and rearrangements of the collagen matrix, which responds to tensile and compressive forces experienced by the cartilage. The superior horns are connected to the hyoid bone via the lateral thyrohyoid ligament, while the inferior horns articulate with the cricoid cartilage. The Axial Skeleton The axial skeleton forms the vertical, central axis of the body and includes all bones of the head, neck, chest, and back The axial skeleton of the adult consists of 80 bones, comprising the skull, the vertebral column, and the thoracic cage. If you do not agree to the foregoing terms and conditions, you should not enter this site.

Wormian or suteral bones are tiny bones between cranial bones. It articulates with the paired arytenoid cartilages posteriorly, as well as providing an attachment for the inferior horns of the thyroid cartilage. The skeletal cartilages include examples from all three. At birth, most bones are well ossified, except for the epiphyses, which form secondary ossification centers C. The appendicular skeleton is made up of all bones of the upper and lower limbs and the girdles which attach them to the axial skeleton. In appositional growth, cartilage-forming cells in the surrounding perichondrium secrete new matrix against the external face of the existing cartilage tissue. It is the only type of cartilage that contains type I collagen in addition to the normal type II.

Laryngeal Cartilages

Arytenoid Cartilages The arytenoid cartilages are pyramidal shaped structures that sit on the cricoid cartilage. This mode of nutrient delivery limits cartilage thickness. In embryos, the skeleton is predominantly composed of hyaline cartilage, but in the adult, most of the cartilage is replaced by more rigid bone. This lack of blood supply causes cartilage to heal very slowly compared with bone. To identify surface bone markings and functions. They form the laryngeal skeleton, which provides rigidity and stability. Hyaline cartilage is the most widespread cartilage type.

They give elastic cartilage great flexibility so it can withstand repeated bending. These fibers form bundles that appear dark under a microscope. Some anatomists also recognize two other subcategories of bones. Corniculate Cartilages The corniculate cartilages are minor cartilaginous structures. The principal protein is elastin. Key Terms chondroitin sulfate : an important structural component of cartilage that provides much of its resistance to compression connective tissue : a type of tissue found in animals whose main function is to bind other tissue systems such as muscle to the skin or organs hyaline cartilage : a type of cartilage found on many joint surfaces; it contains no nerves or blood vessels, and its structure is relatively simple chondrocytes : cells that form and maintain the cartilage extracellular matrix: the non-cellular component present within all tissues and organs, and provides not scaffolding and biochemical reactions avascular: there are no vessels to carry blood to cartilage tissue cartilage: rubber-like padding that covers and protects the ends of long bones at the joints elastin: protein of the extracellular matrix which is highly elastic tendon: fibrous connective tissue that connects muscle to bone collagen: the main structural protein in various connective tissues.

The primary functions of the skeleton are to provide a rigid, internal structure that protects internal organs and supports the weight of the body, and to provide a structure upon which muscles can act to produce movements of the body. Bone Development Compare and contrast intramembranous ossification and endochondral ossification. The patellas kneecaps are sesamoid bones. The appendicular skeleton consists of 126 bones and includes all bones of the upper and lower limbs. Cartilage persists only in such isolated areas as the external ear, bridge of the nose, larynx, trachea, joints, and parts of the rib cage.

Bones that do not tall into one of the preceding categories are classified as irregular bones. Classification of Joints Fibrous joints F. Elastic cartilage has the most ECM; hyaline a middle amount; and fibrous cartilage has the least amount of ECM. It is a component of the respiratory tract, and has several important functions, including phonation, the cough reflex, and protection of the lower respiratory tract. It is commonly found in many locations in the body such as bronchi, bronchial tubes and trachea.
