Answer 1

Q.1) Cortical Bone slide:—

​​​​​​A) Interstitial Lamellae :- These are present in the space between osteons and found in the shafts of the long bones.

B) Haversian system :- In the cortical bones, this haversian system comprises of osteocytes, lamellae and Haversian Canals.

C) Concentric Lamellae :- In the cortical bones, blood vessels are surrounded by three to eight concentric lamellae.

D) Haversian Canals :- These are the series of microscopic tubes in the outermost region of compact bone and it runs up the center of the osteon, contains blood vessels and nerves.

Q.2)  Trabecular bone slide :—

​​​​​​A) Trabeculae :- These are present in the spongy bones.​ These are the interconnecting plates that bear weight and help the bone resist bending and twisting. They provide structural support and strength to the spongy bones.

B) Marrow cavity:- Marrow cavity is the central cavity of bone shafts where red or yellow bone marrow is stored.

Q.3)  

1.) cortical bones are compact,heavy and very tough and made up of osteons

while trabecular bones are spongy ,light and soft , and made up of loosely packed trabeculae.

2.) Lamellae in the compact bones are arranged in the haversian system while in trabecular bone, lamellae are present in interlocking system.

3) Cortical bones are much denser than the trabecular bones.

4) Cortical bones forms the diaphysis of the long bones while trabecular bones forms epiphysis of the long bones.
