Some of the structures of the biceps and triceps are:
- The epimysium, which acts as a membrane for the muscles.
- Muscle fascicles, which makes up the muscle.
- The perimysium, which acts as a membrane for the fascicles.
- Muscle fibers, which make up the fascicles.
- The sarcolemma, which acts as a membrane for the fibers.
Biochemistry
- Glucose, which is located in the blood, gives energy to the muscle cells.
- Myosin is located in the muscles and it allows shortening in the muscles.
- Vitamin E heals wounds and prevents tissue scarring.
Interaction Between Other Organ Systems
- It interacts with the nervous system when the nervous system controls everything the muscles do.
- The skeletal muscles move the bone and are connected through tendons.
- There are muscle cells in the esophagus (digestive system), diaphragm (respiratory system) and veins and arteries (circulatory system).
Interaction Inside Organ Systems
- The biceps and triceps work as antagonists.
- When the biceps contracts, the triceps has to relax and the other way around.
Interesting Facts:
- Both of the biceps combined are about three percent of all muscle mass.
- Moustafa Ishmial holds the world record for largest biceps/triceps with a 31 inch circumference and no artificial steroids.
