What is found in cancellous bones?
Cancellous bone (also known as spong bone) is spongy, soft and found within flat bones and at the ends of long bones. It contains the bone marrow, fat and blood vessels within it.
Where are osteocytes located?
lacunae
Osteocytes (Ot) are located within lacunae surrounded by mineralized bone matrix (B).
Are osteoblasts found in spongy bone?
Osteoblasts are cells that make new bone. They become osteocytes, the cells of mature bone, when they get trapped in the matrix. Osteoclasts engage in bone resorption. Compact bone is dense and composed of osteons, while spongy bone is less dense and made up of trabeculae.
Does compact bone have osteoclasts?
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.
Does spongy bone have osteocytes?
Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles. Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) ((Figure)).
Are osteocytes found in spongy bone?
Spongy (Cancellous) Bone. Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles. Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) ((Figure)).

| Which of the following structures contain osteocytes? | Lacunae |
| These are extensions of the lacuanae and are filled with extracellular fluid | Canaliculi |
| Osteons in compact bone tissue are aligned along | Lines of stress |
| Bone remodeling does NOT | Affect compact bone tissue but des affect spongy bone tissue |
What is the difference between cortical and cancellous bone?
Cortical bone is a dense tissue that contains less than 10% soft tissue. Cancellous or spongy bone is made up of trabecules shaped as plates or rods interspersed between bone marrow that represents more than 75% of the cancellous bone volume.
What is the difference between osteocytes and osteoclasts?
When the area surrounding an osteoblast calcifies, the osteoblast becomes trapped and transforms into an osteocyte, the most common and mature type of bone cell. Osteoclasts, the cells that break down and reabsorb bone, stem from monocytes and macrophages rather than osteogenic cells..
Are there osteocytes in spongy bone?
Where are chondrocytes and osteocytes located?
Chondrocytes are located in the cartilage of the body and osteocytes are located in the bone.
