What is the main function of bone tissue?Explanation / Answer
39 - cartilage consists of chondrocytes that produce collagenous extracellular matrix and ground substance rich in proteoglycan.
40- Hyaline cartilage provides flexibility and support to the different body parts as it is high in collagen.
41 -Fibrocartilage prevent bone to bone contact and resists compression.it also limits relative movements.
42- Elastic cartilage provides support and tolerates distortion against damage and returns back to its original shape.
43 -Chondroblasts will form chondrocytes in the growing cartilage matrix.
44- Bone is formed from 3 primary cell types ie Osteoblasts ,Osteocytes and Osteoclasts.
45- Apart from collagen fibres,bone is made up of inorganic bone mineral which form small crystals and small percent of water.
46 - Chondrocytes are the cells in the cartilage which produce and maintain the cartilage matrix.
47 - Osteoblasts produce bone matrix and increases the bone mass.
48 -Osteocytes help to form bone and they act as channels for the exchange of nutrients and waste through gap junctions.
49 - Osteoclasts are responsible for bone reabsorption .Osteoclasts secrete some digestive enzymes that break up or dissolve bone tissue.
50- Ossseous tissue
51- Bones help in the skeletal support,aids locomotion,protection of soft tissues ,calcium and phosphorous storage and harbouring of bone marrow.
