Detailed explanation-1: -Compact bone: is dense & looks smooth & homogeneous. ii. Spongy bone : (also called cancellous bone) is made of needle-like or flat pieces – trabeculae .

Detailed explanation-2: -Compact bone is smooth, homogenous, and dense. Spongy bone has lots of needle like pieces called trabeculae and lots of spaces. We classify bones by their shape. Long-longer than wide, compact bone outside, some have spongy bone on the interior.

Detailed explanation-3: -Cortical bone tissue gives bone its smooth, dense, solid appearance. It accounts for about 80 percent of the total bone mass of the adult skeleton. Spongy bone tissue fills part or all of the interior of many bones.

Detailed explanation-4: -1) Compact bone: Compact bone is dense and looks smooth, homogeneous and very strong . 2) Cancellous bone (Spongy bone): Spongy bone is composed of long, needle-like pieces of bone and lots of open space. 2. Elastic cartilage Incidence: epiglottis, auricle of the ear and Eustachian tube.

Detailed explanation-5: -Compact bone forms the dense outer shell of bones. It has a smooth and homogeneous appearance. Compact bone is dense and solid in appearance, whereas cancellous (spongy) bone is characterized by open space partially filled with needle-like structures.
