the two proteins that make up muscles fibers are acting and myosin
sacomeres are a single unit of a muscle fiber multiple sacomeres make up a myofibril
Protein.
Actin and myosin are contractile proteins found within muscle fiber. If you look at a muscle fiber under a microscope it is made up of several repeating units called sarcomeres that run along the length of the muscle fiber. Proteins actin and myosin are found in the sarcomeres in different locations.

microfiliments and microtubulars
Muscles are made up of fibers of protein so they use protein to make up damage tissues
microtubules
It is put here short and sweet. 1. Marrow 2. Calcified Bone 3. Periosteum 4. Spongy Bone 5. Cartilage TENDONS attach the MUSCLE to the BONE.Like the stringy thing in a chicken
protein is important because it builds up muscle cells and is usedto repair them if they get damaged.
muscle spindles
Your muscles are building up, and the protein you eat becomes muscle.
