Muscle Types and Differences

What are the three main types of muscles?

• Upper body, lower body, core

• Flexor, extensor, abductor

• Bicep, tricep, quadricep

• Skeletal, cardiac, and smooth muscles

What are the main differences between skeletal muscles, cardiac muscles, and smooth muscles?

• Skeletal muscles are attached to bones and are responsible for movement, cardiac muscles are found in the heart and are responsible for pumping blood, and smooth muscles are found in the walls of internal organs and blood vessels and are responsible for involuntary movements.

• Smooth muscles are responsible for voluntary movements

• Cardiac muscles are attached to bones and are responsible for movement

• Skeletal muscles are found in the heart and are responsible for pumping blood

Which type of muscle is responsible for voluntary movements?

• Skeletal muscle

Which type of muscle is found in the walls of internal organs and blood vessels?

• Smooth muscle

• Rough muscle

• Bumpy muscle

• Uneven muscle

What is the main function of skeletal muscles?

• The main function of skeletal muscles is to regulate body temperature.

• The main function of skeletal muscles is to store energy in the body.

What is the main function of smooth muscles?

• To control the movement of bones

• La función principal de los músculos lisos es controlar la contracción y relajación de los órganos internos, como el estómago, los intestinos y los vasos sanguíneos.

• To produce hormones

Give an example of a voluntary muscle and an involuntary muscle.

• Involuntary muscle: Diaphragm muscle

• Voluntary muscle: Biceps (muscle in the arm) Involuntary muscle: Heart muscle

• Voluntary muscle: Quadriceps (muscle in the thigh)

• Voluntary muscle: Triceps (muscle in the arm)
