Hard tissue are lightweight yet strong and hard, and serve multiple functions. Mineralized osseous tissue or bone tissue, is of two types – cortical and cancellous and gives it rigidity and a coral-like three-dimensional internal structure. Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels and cartilage. Bone is an active tissue composed of different cells. Osteoblasts are involved in the creation and mineralisation of bone; osteocytes and osteoclasts are involved in the reabsorption of bone tissue. The mineralised matrix of bone tissue has an organic component mainly of collagen and an inorganic component of bone mineral
Nerve tissue protein Nerve tissue protein Nerve tissue is a biological molecule related to the function and maintenance of normal nervous tissue. An example would include, for example, the generation of myelin which insulates and protects nerves. These are typically calcium-binding proteins. There are two types of myelin the first is ogliodendrocyte- Myelin which can be found in the mammalian Central Nervous System (CNS) and the second is Schwann cells which are found in the Peripheral Nervous System (PNS). Myelination of axons by these Schwann cells are essential for normal nerve function. Peripheral nerves rely on communication between axons and Schwaan cells. Prion
