. describe the skeletal attachments, action, and innervation
of these muscles.
It is a pattern of striated muscle tissue, which is under the natural supervision of the somatic nervous system.
By tendons, and they generate all the activities in connection to each other. Skeletal muscles are connected to bones
The actions of muscles :
1. Flexion: reducing the angle between two bones (bending).
2 Extension: boosting the angle between two bones (straightening a bend).
1. Abduction: shifting away from the body's midline.
2. Adduction: Moving toward the body's midline.
3. Pronation and supination: Interpreting the rotation of the forearm back and forth requires special terms. Circulate your fingers out and look at the palms of your hands and the fingers and then tighten your palms to look at your nails.
4. Depression and Elevation: For example chewing or shrugging your shoulders. Up-and-down actions,
5. Protraction and retraction: By shifting your jaw back and forth in a jutting motion, you are protracting and retracting your mandible.
6. Inversion and eversion: Overturn your foot when you turn it inward to see what is stuck under your shoe.
7. Dorsiflexion and plantar flexion: You dorsiflex your feet to step on your heels, and plantar flex them to tiptoe.
8. Prime movers and antagonists: The prime mover, sometimes called the agonist, is the muscle that furnishes the primary force riding the action. An antagonist's muscle is in opposition to a prime mover in that it furnishes some resistance and/or reverses a given movement.
