A Correct answer
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.

D Correct answer
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

  1. Support

  2. Support, erythrocyte and leucocyte synthesis

  3. Support and erythrocyte synthesis

  4. Erythrocyte formation
Reveal answer Fill a bubble to check yourself
B Correct answer
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',.
