APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Skeletal muscle is attached by cord-like tendons to bone, such as in the legs, arms, and face. Skeletal muscles are called striated (pronounced: STRY-ay-ted) because they are made up of fibers that have horizontal stripes when viewed under a microscope.

Detailed explanation-2: -Skeletal muscles contract and relax to mechanically move the body. Messages from the nervous system cause these muscle contractions.

Detailed explanation-3: -The three main types of muscle include: Skeletal muscle – the specialised tissue that is attached to bones and allows movement. Together, skeletal muscles and bones are called the musculoskeletal system (also known as the locomotor system).

Detailed explanation-4: -For example, the upper part of your arm has a biceps muscle and a triceps muscle (see the diagram). This pair of muscles work together when you bend your arm at the elbow. As your arm bends, two things happen-the biceps muscle contracts and the triceps muscle relaxes.

Detailed explanation-5: -For example, when you perform a bicep curl the biceps will be the agonist as it contracts to produce the movement, while the triceps will be the antagonist as it relaxes to allow the movement to occur.
