Study Notes
- The muscular system consists of over 600 muscles.
- Muscles are excitable, capable of receiving stimulation and responding by contracting.
- Muscles are irrigative, meaning they can be stretched without damage.
- Muscles have elasticity, able to return to their original shape and length after being stretched or contracted.
- Muscles are adaptable, capable of enlarging or atrophying based on use.
- Muscles perform five major types of movements: adduction (moving toward midline), abduction (moving away from midline), flexion (bending), extension (straightening), and rotation (moving around an axis).
- Muscles are classified into three types: cardiac (involuntary, found in the heart), visceral (smooth, involuntary, found in organs), and skeletal (voluntary, attached to the skeleton).
- The muscular system requires supportive structures like tendons and fascia to function.
- The nervous system is essential for the muscular system's voluntary movements.
- Quadriplegia occurs when communication between the nervous system and skeletal muscles is severed.
- Cardiac muscle is an essential exception, being the only muscle not directly dependent on the nervous system.
