An instructor is describing the process of bone development. Which of the following would the instructor describe as being responsible for the process of ossification?
A) Osteoblasts
B) Cortical bone
C) Osteoclasts
D) Cancellous bone
A
Feedback:
Osteoblasts secrete bone matrix (mostly collagen), in which inorganic minerals, such as calcium salts, are deposited. This process of ossification and calcification transforms the blast cells into mature bone cells, called osteocytes, which are involved in maintaining bone tissue. Cortical bone is dense hard bone found in the long shafts; cancellous bone is spongy bone found in the irregular rounded edges of bone.
