  4. 4 vertebrae

Show answer
Correct Option: D
Explanation:

The four coccygeal vertebrae fuse together in adult to form a single small triangular bone called coccyx. It articulates with the tip of the sacrum.

  1. In the bone of rabbit haversian canal is foun

  2. Yellow marrow is found

  3. Osteocytes are of different types

  4. Bone of frog is spongy

Show answer
Correct Option: A
Explanation:

Within the matrix of the compact bone of the shaft of long mammalian bones. (like humerus, femur, tibia), a network of branching canals (called haversian canals) is present in which lie the blood vessels.

  1. Keel

  2. Synsacrum

  3. Syncytium

  4. Furcula

Show answer
Correct Option: B
Explanation:

Synsacrum is a composite bone in birds which consists of about 16 fused vertebrae of different regions.

Deltoid ridge is found in which one of the following bones

biology our skeletal system and the skin bones and movements joints in the human body joints

  1. Radius

  2. Tibia

  3. Femur

  4. Humerus

Show answer
Correct Option: D
Explanation:

Humerus is differentiated into three parts head, shaft and lower end. Shaft has a V-shaped deltoid ridge, at its middle.

Extremities of long bones possess 

biology our skeletal system and the skin bones and movements joints in the human body joints

  1. Calcified cartilage

  2. Fibrous cartilage

  3. Elastic cartilage

  4. Hyaline cartilage

Show answer
Correct Option: D
Explanation:
  • Long bones are hard, dense bones that provide strength, structure, and mobility. For example, The thigh bone (femur) is a long bone.
  • Articular cartilage is hyaline cartilage that is found on the articular surfaces of bone i.e where bones meet and form joints.
  • Hence  Extremities of long bones possess Hyaline cartilage(articular cartilage).
  • So, the correct answer is 'Hyaline cartilage'.

Long bones function in

biology our skeletal system and the skin bones and movements joints in the human body joints

  1. Support

  2. Support, erythrocyte and leucocyte synthesis

  3. Support and erythrocyte synthesis

  4. Erythrocyte formation

Show answer
Correct Option: B
Explanation:
  • Long bones are hard, dense bones that provide strength, structure, and mobility, typically found in the upper and lower extremities (arms and legs). For example, the femur (thigh bone) is a good example of a long bone.
  • Haemopoiesis(production of blood cells) takes place in epiphyses of long bones.
  • As long bones are hard and dense they provide support and they function as the synthesis of erythrocyte and leucocyte due to the presence of red bone marrow.
  • So, the correct answer is 'Support, erythrocyte, and leucocyte synthesis',.
