What is common btw froction and muscular force

Dear student, 
Please find below the solution to the asked query        

Both frictional force and muscular force needs to be in contact with the body on which they are acting. Hence, they are contact forces.

In frictional force, the force acts between the surfaces in contact. In muscular force the force acts on a body at the point where we touch it to push or pull it.
