Study Notes
Learning Objectives
- Understand skeletal muscle structure and the molecular mechanisms behind skeletal muscle contraction.
- Comprehend the control of motor movement and factors influencing muscle strength.
Types of Muscles
- Muscle tissue is the largest group of tissues in the human body.
- Three primary types of muscle:
- Skeletal Muscle: Forms the muscular system; primarily under voluntary control.
- Cardiac Muscle: Exclusive to the heart; involuntary control.
- Smooth Muscle: Found in hollow organs and tubes throughout the body; also involuntary.
- Classification of muscles based on:
- Striation: Includes striated (skeletal and cardiac) and unstriated (smooth) muscle.
- Control: Divided into voluntary (skeletal) and involuntary (cardiac and smooth) muscles.
Muscle Function
- Controlled contractions of muscle enable:
- Purposeful movement of the body and its segments.
- Manipulation of external objects.
- Propulsion of contents within hollow internal organs.
- Efficient emptying of contents from specific organs.
