GENERAL HISTOLOGY

Detailed explanation-1: -Lamellae are found in both compact and cancellous bone, but lacunae are only found in cancellous bone.

Detailed explanation-2: -Osteocytes are found within lacunae. Giant multinucleated osteoclasts, which break down bone, are occasionally found in lacunae termed Howship’s lacunae. These are readily found in the ossification zone of the growth plate. The compact bone in this slide surrounds the marrow cavity and spongy bone.

Detailed explanation-3: -Compact bone tissue is composed of osteons and forms the external layer of all bones. Spongy bone tissue is composed of trabeculae and forms the inner part of all bones. Four types of cells compose bony tissue: osteocytes, osteoclasts, osteoprogenitor cells, and osteoblasts.
