Osteocytes are bone cells. Special ones that build bone are called osteoblasts (blast=build) and ones that break down bone are called osteoclasts (clasts=break).
Osteoblasts
Osteoclasts
Cells that form bones are called osteoblasts.
Tissue made of cells that contract and relax to produce movement is called muscle tissue.
connective tissue
Tissue made of cells that contract and relax to produce movement is called muscle tissue.
What defines a connective tissue is living cells surrounded by a non-living extracellular matrix. The red and white blood cells are the living cells and the plasma they float in is the non-living extracellular matrix therefore blood is classified as a connective tissue.
cytes
Bone cells are called osteocytes, and the matrix of the bone is made of calcium salts and collagen. Bone tissue is the major structural and supportive connective tissue of the body.
Extracelluar Matrix
Tissue made of cells that contract and relax to produce movement is called muscle tissue.
Cells that form bones are called osteoblasts.
They're called OSTEOCYTES calcifying together in a matrix tissue of bone matter.
Tissue made of cells that contract and relax to produce movement is called muscle tissue.
connective tissue
Tissue made of cells that contract and relax to produce movement is called muscle tissue.
What defines a connective tissue is living cells surrounded by a non-living extracellular matrix. The red and white blood cells are the living cells and the plasma they float in is the non-living extracellular matrix therefore blood is classified as a connective tissue.
The cells are often bound to the extracellular matrix by proteins in the plasma membrane. The extracellular matrix is the structural support of tissue.
Cartilage is composed of cells called chondrocytes. Chondrocytes produce extracellular matrix of collagen fibers, ground substance, and elastin. Cartilage is the only connective tissue that does not contain blood vessels.
