Characteristics Most abundant tissue regenerates at varying rates relatively few cells and widely separated from each other. Found in bone, blood, ligaments, cartilage.
Functions 1.Support 2.Binding 3.Protection 4.Transport 5.Storage 6.Fills space
Types Identified by cells and matrix Matrix: complex mixture of nonliving material that makes up the extracellular matrix (ECM). Human Blood tissue and its surrounding matrix
Cartilage Solid, rubbery matrix. Cartilage is found in the joints, the rib cage, the ear, the nose, in the throat and between intervertebral disks.
Cartilage Chondrocytes Cells found within the matrix, live in small pockets know as lacunae (lacus-pool).
Matrix non-living collagen (protein) fibers. No blood vessels (diffusion) 3 types: –Hyaline-white –Elastic-flexible –Fibrocartilage- very tough
The osteoarticular transplant (OATs) procedure. A. A region of damaged cartilage is evident on the femur (circled region). B. The lesion and any abnormal surrounding cartilage are removed, leaving a recipient site of normal bone and cartilage (C). A size- matched, donor allograft femur with healthy cartilage and bone is used to obtain a donor plug of bone and cartilage (inset).

Bone Solid, crystalline matrix, vascular, will heal back Cells osteocytes Matrix inorganic calcium, flexible collagen fibers. Diffusion occurs through the canaliculi in the bony matrix to distribute nutrients
