8. The action of the muscle is what effect is produced by the muscles contraction. The innervation is the peripheral nerve that supplies a muscle with the message from the brain1. Cardiac, skeletal and smooth2. Skeletal muscles are under conscious control, meaning that a personcan consciously decide to use these muscles to complete an action.3. Brain and spinal cord4. Messages from the central nervous system to a muscle are called a motor actions. Nerves also carry information from the external environment to the central nervous system, called sensation or sensory input.5. False6. Tendons are connective tissues that connect skeletal muscle to boneat each end. Ligaments are connective tissue that connects bone to bone, helping to stabilize joints where bones meet.7. The origin is the bony site of attachment which is stationary during the movement. The insertion of a muscle is the bony site of attachment that is moved by the muscle contraction.8. The action of the muscle is what effect is produced by the muscle’s contraction. The innervation is the peripheral nerve that supplies a muscle with the message from the brain.
