slide 60 on muscles of respiration
What is the function of the vertebral column?
Support: Helps keep the body upright and balanced.
Protection: Shields the spinal cord from injury.
Movement: Provides flexibility and range of motion through various vertebrae and joints.
Attachment: Provides attachment points for ribs and muscles that aid in respiration.
What is the difference between motor units and motor pools?
A motor unit is a motor neuron and all the muscle fibers it controls.
A motor pool is is a group of motor neurons that control a single muscle.
What is the basic function of prime movers?
