Question

difference between bone and cartilage with respect to structure,function and locations?​

Answer 1

Explanation:

Bones form the skeletal structure of the body, whereas cartilage is present in nose, ear, ribs, larynx, and joints and also act as a shock absorber in these joints. ... Bones protect against the mechanical damage and supports the movement of the body, provide shape to the body.

★ Bones

• Bones are the hard, inelastic and a tough organ that forms part of the vertebral skeleton.
• Bones are of two types: compact or spongy.
• Bone cells are known as osteocytes.
• Function -The function of the skeleton / bone is as a static structural organ supporting body movement, protecting the internal organs, and as a reservoir of minerals 2.
• Location - Long bones are mostly located in the appendicular skeleton and include bones in the lower limbs (the tibia, fibula, femur, metatarsals, and phalanges) and bones in the upper limbs (the humerus, radius, ulna, metacarpals, and phalanges).
• Structure - the basic structure of bones is bone matrix, which makes up the underlying rigid framework of bones, composed of both compact bone and spongy bone. The bone matrix consists of tough protein fibers, mainly collagen, that become hard and rigid due to mineralization with calcium crystals.

★ Cartilage

• Cartilage is a soft, elastic and flexible connective tissue that protects the bone from rubbing against each other.
• Cartilage is of three types: Hyaline cartilage, fibrocartilage, and elastic cartilage.
• Cartilage cells are known as chondrocytes.
• Function - It keeps joint motion fluid by coating the surfaces of the bones in our joints and by cushioning bones against impact. It is not as rigid as bone, but is stiffer and less flexible than muscle tissue.
• Location - It is found in many areas of the body including: Joints between bones e.g. the elbows, knees and ankles. Ends of the ribs. Between the vertebrae in the spine.
• Structure - Cartilage is composed of specialized cells called chondrocytes that produce a large amount of collagenous extracellular matrix, abundant ground substance that is rich in proteoglycan and elastin fibers. Cartilage does not contain blood vessels (it is avascular) or nerves (it is aneural).
