![]() Growth occurs by a lengthening of the diaphysis. Bones also store vital minerals and produce red and white blood cells.\( \newcommand\): Long bone: A long bone is longer than it is wide. Osseous tissue consists primarily of osteoblasts which makes the proteins and molecules needed to form the fibers and the ground substance which makes up the extracellular matrix.īONE AS AN ORGAN: When we refer to bones as an organ, we include not only the osseous tissue, but also the cartilage, nervous tissue, the epithelial tissue (in the form of blood vessels) and the fibrous connective tissue that functions together as a unit. A bone is an organ that makes up a large portion of the human skeleton. Bones function in your body to support and protect your internal organs and to allow for mobility. Even though our bones consist primarily of osseous tissue, they also contain nervous tissue in their nerves, fibrous tissue lining their cavities, and muscle and epithelial tissue in their blood vessels.īONE AS A TISSUE: Bone tissue (or osseous tissue) is a type of connective tissue. An organ is made of different tissue types which come together to form a unit that has a specific function in the body. Respiratory Cartilage – makes up the larynx and epiglottis and reinforces air passagesīones are considered a tissue and an organ.Costal Cartilage – connects the ribs to the sternum.Articular Cartilage – covers the ends of most bones.The human body has 3 categories of cartilage based on their location. This cartilage is found in areas of our body that undergo a lot of mechanical stress due to compression and tension forces, like our knee joints and invertebral discs. The strongest cartilage in our bodies is fibrocartilage. It forms the external portions of our ears and our epiglottis, which acts to keep food out of your trachea. Elastic Cartilage - The rarest type of cartilage is elasic cartilage.It provides a smooth surface within our joints for movement. ![]() Hyaline Cartilage, - The majority of our cartilage is hyaline cartilage.This area is involved in the formation of red blood cells and white blood cells, and the calcium supply for bird eggshells. ![]() Cartilage of our skeleton can be categorized either by their histological features, or by their location in the body.Ĭartilage is a connective tissue that is separated into 3 main types However, the medullary cavity is the area inside any bone (long, flat, etc.) that holds the bone marrow. ![]()
