Ligament
Flexible tough band of fibrous connective tissue that attaches one bone to another at a joint
Tendon
Band of fibrous connective tissue that attaches muscle to bone
Aponeurosis
Strong sheet of tissue that acts as a tendon to attach muscle to bone
Skeletal muscles
Attached to bones by tendons and make body movement possible. Skeletal muscles produce action by pulling and working in pairs. They are voluntary muscles because we have control over them.
Smooth muscles
Located in internal organs such as the walls of blood vessels and the digestive tract. They respond to impulses from the autonomic nerves and are not controlled voluntarily.
