Anatomy of the Muscular system: Introduction & Muscles of the Head, Neck and Trunk
1. Name the three types of muscle tissue found in the body:
2. What does it mean that skeletal muscles are under conscious control?
3. What is included in the central nervous system?
4. Describe a motor action vs. sensory input in terms of the nervous system.
5. True or false: The brachial plexus supplies nerves to the lower extremities.
6. Describe the difference between tendons and ligaments.
7. Describe the origin and insertion of attachment to bones.
8. Describe muscle action and innervation.
1. Cardiac, skeletal and smooth
2. Skeletal muscles are under conscious control, meaning that a person can consciously decide to use these muscles to complete an action.
3. Brain and spinal cord
4. 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. False
6. Tendons are connective tissues that connect skeletal muscle to bone at 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.
Question 2
9. Make a chart for the origin, insertion, action and innervation for the following muscles:
*Note: All muscles listed in the module will need to be memorized for the exam. This is not an exhaustive list. Making a chart to organize the
information is a helpful way to study the muscles. You may want to make a full chart on your own to study and review for the exam.
