Question

In the structure of a muscle, several fascicles lie bundled together to form a muscle, just as several lie together to form compact bone tissue. Each muscle fiber, which is a muscle cell, consists of protein fibers. Similarly, the matrix that lies outside bone cells consists of a protein fiber called .

Answer 1

Compact bone tissue is one of the two types of bone tissue. The other one is called spongy bone tissue. Compact bone has a higher density, as the name implies, compared to spongy bone. They are made up of closely packed osteons.

The matrix that lies outside the bone cells is called connective tissues. Connective tissues are made up of collagen fibers and a combination of other elastin fibers.

Step-by-step explanation:

Answer 2

Collagen is a protein fiber that is found in the matrix that lies outside the bone cells. Population of these collagen fibers that scattered through the matrix are embedded in a gel-like ground substance called hyaline cartilage, which is flexible but avascular and contains no nerves or blood vessels.
