Study Notes
Characteristics of Muscle Tissue
- Muscle tissue is a type of tissue that has the ability to contract and relax
- It is found throughout the body and is necessary for movement, balance, and posture
- Muscle tissue is made up of muscle fibers, which are multinucleated and have multiple nuclei
Types of Muscle Tissue
-
Skeletal Muscle:
- Voluntary muscle tissue
- Attached to bones and helps move the body's skeleton
- Examples: biceps, quadriceps, hamstrings
-
Smooth Muscle:
- Involuntary muscle tissue
- Found in the walls of hollow organs, such as the digestive tract, blood vessels, and airways
- Examples: muscles in the intestinal wall, blood vessel walls
-
Cardiac Muscle:
- Involuntary muscle tissue
- Found in the heart and responsible for pumping blood throughout the body
- Examples: heart muscle
Functions of Muscle Tissue
- Movement and locomotion
- Support and stabilization of joints
- Regulation of body temperature
- Maintenance of posture and balance
- Assisting in respiration and circulation
Properties of Muscle Tissue
- Excitability: Muscle tissue can respond to stimuli and contract
- Contractility: Muscle tissue can contract and generate force
- Elasticity: Muscle tissue can return to its original shape after contraction
- Extensibility: Muscle tissue can be stretched and lengthened
