Which type of muscle is involuntary and found in the heart?

• Voluntary muscle

• Skeletal muscle

• Cardiac muscle

• Smooth muscle

What is the primary function of skeletal muscles?

• Regulating body temperature through sweat.

• Facilitating movement of the body.

• Providing structural support to bones.

• Storing energy for cellular processes.

How do smooth muscles differ from skeletal muscles?

• Smooth muscles are found only in the heart.

• Smooth muscles differ from skeletal muscles in that they are involuntary and non-striated, whereas skeletal muscles are voluntary and striated.

What is the role of ligaments in the skeletal system?

• Ligaments act as shock absorbers in the skeletal system.

• Ligaments connect muscles to bones and facilitate movement.

• Ligaments are responsible for producing blood cells in the bones.
