Frowning primarily involves the contraction of the corrugator supercilii and the procerus muscles, which are located in the forehead and between the eyebrows. The corrugator supercilii pulls the eyebrows downward and together, while the procerus helps to wrinkle the skin over the bridge of the nose. Additionally, the depressor anguli oris, located at the corners of the mouth, contributes to the downward movement associated with frowning. Together, these muscles create the characteristic facial expression of displeasure or concern.
The frowning action.
The biceps muscle relaxes!!!!!=)
concentric
"Caleotidomastusidialis" element maskes the muscles contract.
Myosin and Actin
A living muscle needs oxygen in the blood and muscle elasticity to contract and move.
Smooth muscle cells contract in response to fluid flow.
Please make your question clearer and resubmit. All muscle fibers contract. What do you mean by constriction?
No, as the muscle is dead (it doesn't contract like while the muscle is still alive either). However, it will contract if you give it an electrical "jump."
it is tiny muscle fibers that contract and expand the muscle
The name of the long cells that can stretch and contract in the body are called muscle fibers. These fibers make up our muscles and are responsible for movement and generating force in the body.
The muscle tissue's main function is to contract.
