Why do we need both compact and spongy bone?

They make up the long bones in the body….Spongy vs Compact Bones.Spongy BonesCompact BonesThey light, spongy and soft in natureThey are heavy, tough and compact in natureThey are made up of trabeculaeThey are made up of osteonsThey fill the inner layer of most bonesThey fill the outer layer of most bones4 more rows

What do osteoclasts produce?

Osteoclasts produce a number of enzymes, chief among them acid phosphatase, that dissolve both the organic collagen and the inorganic calcium and phosphorus of the bone.

What is an osteoblast?

OSTEOBLASTS are the cells that form new bone. They also come from the bone marrow and are related to structural cells. They have only one nucleus. Osteoblasts work in teams to build bone. They produce new bone called “osteoid” which is made of bone collagen and other protein.

How do osteocytes develop?

Osteogenic cells are undifferentiated and develop into osteoblasts. When osteoblasts get trapped within the calcified matrix, their structure and function changes; they become osteocytes. Osteoclasts develop from monocytes and macrophages and differ in appearance from other bone cells.

What are the stages of bone growth?

The process of bone formation is called osteogenesis or ossification. After progenitor cells form osteoblastic lines, they proceed with three stages of development of cell differentiation, called proliferation, maturation of matrix, and mineralization.

How do osteocytes receive nutrients?

The osteocytes in spongy bone are nourished by blood vessels of the periosteum that penetrate spongy bone and blood that circulates in the marrow cavities. As the blood passes through the marrow cavities, it is collected by veins, which then pass out of the bone through the foramina.

What foods help bones heal faster?

Good sources: Milk, yogurt, cheese, cottage cheese, broccoli, turnip or collard greens, kale, bok choy, soy, beans, canned tuna or salmon with bones, almond milk, and fortified cereals or juice.

What do bone cells secrete?

Collagen comprises about 90% of the organic bone matrix. Type I collagen is the most abundant form of intrinsic collagen found in the bone that is secreted by osteoblasts. Most of the non-collagenous organic materials are endogenous proteins produced by the bone cells.

What are the two types of osteocytes?

Osteocytes, the living cells of bone tissue, form the mineral matrix of bones. There are two types of bone tissue: compact and spongy.

Where are osteocytes found?

Osteocyte, a cell that lies within the substance of fully formed bone. It occupies a small chamber called a lacuna, which is contained in the calcified matrix of bone. Osteocytes derive from osteoblasts, or bone-forming cells, and are essentially osteoblasts surrounded by the products they secreted.

What are the small cavities that contain osteocytes called?

Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae. Small channels (canaliculi) radiate from the lacunae to the osteonic (haversian) canal to provide passageways through the hard matrix.

What are the 4 types of bone cells?

Bone is a mineralized connective tissue that exhibits four types of cells: osteoblasts, bone lining cells, osteocytes, and osteoclasts [1, 2]. Bone exerts important functions in the body, such as locomotion, support and protection of soft tissues, calcium and phosphate storage, and harboring of bone marrow [3, 4].

What stimulates osteoblast activity?

Hormones That Influence Osteoclasts Two hormones that affect the osteoclasts are parathyroid hormone (PTH) and calcitonin. PTH stimulates osteoclast proliferation and activity. As a result, calcium is released from the bones into the circulation, thus increasing the calcium ion concentration in the blood.

What do osteocytes do?

The potential functions of osteocytes include: to respond to mechanical strain and to send signals of bone formation or bone resorption to the bone surface, to modify their microenvironment, and to regulate both local and systemic mineral homeostasis.
