Question

Osteoblasts are found in
(a) Blood
(b) Muscle
(c) Bone
(d) Cartilage

Answer 1

Hint: Osteoblasts are found in a rigid organ that, in animals, forms part of the vertebrate skeleton. They provide the body with structure and support, and allow for mobility. To develop this organ, osteoblasts function in teams.

Complete answer:
In bones, osteoblasts are found. The other two cell types which are present in the blood are osteocytes and osteoclasts. It is primarily traced, along with the periosteum and endosteum, in the growing portions of bone. It has no power to split. It synthesizes the collagen matrix and calcium salts and secretes them. It gets stuck and facilitates their differentiation into osteocytes within the bone matrix they secrete.
Osteoblasts are the cells needed, both during initial bone formation and during bone remodeling, for bone synthesis and mineralization.
Many substances, like growth factors, collagenase, osteocalcin, alkaline phosphatase, and collagen, are generated by osteoblasts.
The cells become flat and look like pancakes when the team of osteoblasts has finished filling in a cavity. They line the bone's surface. Lining cells are often referred to as these old osteoblasts. They control the passage of calcium into and out of the bone and, by producing unique proteins that activate the osteoclasts, they respond to hormones.
So, the correct answer is, ‘(c) Bone’.

Note: The cells that form new bone are osteoblasts. They often come from the marrow of the bone and are associated with structural cells. On the bone surface, osteoblast cells are present in the form of a tightly packed sheet, through which processes spread into the forming bone from the osteoblast body. Eventually, the bone matrix expands to surround osteoblasts and the substance of the bone is calcified. The osteoblast becomes a mature bone cell referred to as an osteocyte until it is surrounded and stuck.
