Muscles

Muscles. Prime Mover = responsible for movement i.e. Biceps brachii = forearm flexion Antagonists = resists movement of prime mover i.e. Triceps brachii = forearm extension Synergists = Aid prime movers i.e. Brachioradialis for forearm flexion. Muscles. Of the head and face

Muscles. Muscles work by contracting. Muscles pull. A pair is needed to move a bone two ways. An antagonistic pair. A muscle is made up of bundles of muscle cells. Muscle cells are made of bundles of myofibrils. These are groups of protein fibres.

Muscles

Muscles . Every movement of your body depends on muscles. There are three different types of muscles: INVOLUNTARY MUSCLE (SMOOTH) - is found in the body’s internal organs. It performs its function without any conscious control, but usually quite slowly.
