3 Νοε 2023 · Bone is the tissue that comprises the body skeleton. Like all connective tissues, bone is composed of cells within an extracellular matrix of fibers (predominantly collagen type 1) and ground substance. The extracellular bone matrix is mineralized and arranged in circular layers called lamellae.
11 Οκτ 2020 · Bone is a specialized connective tissue type. Instead of an aqueous extracellular matrix, the ground substance is mineralized and hard. High levels of collagen fibers make our bones shock-resistant by absorbing energy. Furthermore, bones are covered by a connective tissue membrane called the periosteum.
5 Μαρ 2023 · Connective tissue is one of the basic tissue types of the body. As its name implies, "connective tissue" refers to several body tissues that connect, support, and help bind other tissues.
23 Οκτ 2022 · Bone, or osseous tissue, is a hard, dense connective tissue that forms most of the adult skeleton, the support structure of the body. In the areas of the skeleton where bones move (for example, the ribcage and joints), cartilage, a semi-rigid form of connective tissue, provides flexibility and smooth surfaces for movement.
The cellular layer is adjacent to the cortical bone and is covered by an outer fibrous layer of dense irregular connective tissue (see Figure 6.3.4a). The periosteum also contains blood vessels, nerves, and lymphatic vessels that nourish compact bone. Tendons and ligaments attach to bones at the periosteum.
10 Αυγ 2023 · Bone is a modified form of connective tissue which is made of extracellular matrix, cells and fibers. The high concentration of calcium and phosphate based minerals throughout the connective tissue is responsible for its hard calcified nature.
The outer boundary of bone is composed of compact bone tissue, and from the ends, and the rest of the bone interior is composed of cancellous or spongy bone tissue. The bone is covered in connecting tissue called the periosteum. Compact bone tissue forms the extremely hard outside layer of bones.
