Answer:

Walking

Explanation:

A muscle cell usually contracts or expands simultaneously when one is working or doing some activities like running, exercises, house chores e.t.c

Muscles are flexible fibers that are very essential appendages for locomotion in human beings.

For muscle cells to contract, they are pulled together thereby causing tension in the muscle. When they are relaxed, they move away from one another.

devlian [24]

The order is calcification of matrix  >> cells differentiate into osteoblasts >> formation of the primary ossification >>  osteoclasts break down the spongy bone >> formation of the secondary ossification (5,3,1,2,4). It is a fundamental process.

<h3>What are osteoblasts?</h3>

Osteoblasts are cells of the bones, which act to generate bone matrix and modulate the process of mineralization of the skeleton.

Endochondral ossification refers to the mechanism through which the cartilaginous bones generate longitudinal growth.

This mechanism (endochondral ossification) is fundamental during fetal/embryo development.
