Central Nervous System (CNS)
- The CNS is the command center of the nervous system.
- The CNS consists of the brain and spinal cord.
Peripheral Nervous System (PNS)
- The PNS is responsible for transmitting messages between the CNS and the rest of the body.
- The PNS is composed of nerves that act as speedy messengers.
The Muscular System
- Muscles produce movement through contraction and relaxation.
Types of Muscles
- There are 3 basic forms of muscle: skeletal, smooth, and cardiac.
Total Muscles in the Human Body
- The human body has 650 muscles in total.
Movement Process
- The brain, nerves, and skeletal muscles work together to produce movement.
Functions of Muscles
- Movement: muscles enable movement of body parts.
- Posture: muscles help maintain posture.
- Body Temperature: muscles help regulate body temperature.
- Contraction of the heart: cardiac muscles are responsible for heart contraction.
- Construction of organs and vessels: muscles help construct and maintain organs and vessels.
