Why is bone considered a tissue?

Bone is a connective tissue containing cells, fibers and ground substance. Bone is unique because its collagen framework absorbs energy, while the mineral encased within the matrix allows bone to resist deformation.

Is bone a tissue?

Bone is living tissue that makes up the body’s skeleton. There are 3 types of bone tissue: Compact tissue. This is the harder, outer tissue of bones.

Is bone considered a tissue or an organ?

Bones are organs that consist primarily of bone tissue, also called osseous tissue. Bone tissue is a type of connective tissue consisting mainly of a collagen matrix that is mineralized with calcium and phosphorus crystals.

Why are blood and bone considered connective tissue?

Blood is considered a connective tissue because it has a matrix. The living cell types are red blood cells, also called erythrocytes, and white blood cells, also called leukocytes. Mammalian erythrocytes lose their nuclei and mitochondria when they are released from the bone marrow where they are made.

Why are bones porous?

The porosity of bone is the volume fraction of bone which is not occupied by bone tissue. Cortical porosity is due to a complex network of intracortical canals and spaces, while trabecular porosity is due to the intertrabecular marrow spaces.

What tissues are part of the bone?

Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts.

What cells are in bone tissue?

There are three types of cells that contribute to bone homeostasis. Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells. An equilibrium between osteoblasts and osteoclasts maintains bone tissue.

Is bone marrow a tissue?

The soft, spongy tissue that has many blood vessels and is found in the center of most bones. There are two types of bone marrow: red and yellow. Red bone marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets.

Why is bone a connective tissue class 9?

Bones: Bone is the hardest connective tissue and helps in maintaining the shape and posture of the body, it protects internal organs. They are rich in collagen fibres and calcium, which give strength. The cells of the bone are known as osteocytes. They are present in lacunae and secrete the matrix.

Why are bones hollow?

Often there is a jelly-like area in the centre of the bone, which is called the bone marrow. Bone marrow produces the body’s blood cells. So, bones are actually hollow tubes, a bit like bamboo which is a type of plant. A hollow structure means that the weight of the bone is a lot less than it would be if it were solid.

What cell produces bone tissue?

Osteoblasts
There are three types of cells that contribute to bone homeostasis. Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells. An equilibrium between osteoblasts and osteoclasts maintains bone tissue.
