ANATOMY

Detailed explanation-1: -Your endocrine system works closely with your brain and central nervous system to control the creation of specific hormones and enzymes. Your digestive and excretory systems work with the nervous system in both conscious and unconscious ways.

Detailed explanation-2: -The somatic nervous system is a component of the peripheral nervous system associated with the voluntary control of the body movements via the use of skeletal muscles.

Detailed explanation-3: -Your nervous system (brain and nerves) sends a message to activate your skeletal (voluntary) muscles. Your muscle fibers contract (tense up) in response to the message. When the muscle activates or bunches up, it pulls on the tendon. Tendons attach muscles to bones.

Detailed explanation-4: -integration of three systems: the nervous, skeletal, and muscular systems. These systems work in concert to produce motion (kinetic) or human movement.
