Muscles and Body MovementsMovement results when a muscle moves an attached bone Muscles are attached to at least two points Origin Attachment to a immoveable bone Insertion Attachment to an movable bone
Muscles and Body Movements
Types of Ordinary Body MovementsFlexion Decreases the angle of the joint Brings two bones closer together Typical of hinge joints like knee and elbow Extension Opposite of flexion Increases angle between two bones
Types of Ordinary Body Movements
Types of Ordinary Body MovementsHyperextension: results when angle is > 180 ̊
Types of Ordinary Body MovementsRotation Movement of a bone around its longitudinal axis Common in ball-and-socket joints Example is when you move atlas around the axis vertebra (shake your head “no”)
Types of Ordinary Body MovementsAbduction Movement of a limb away from the midline Adduction Opposite of abduction Movement of a limb toward the midline
Types of Ordinary Body MovementsCircumduction Combination of flexion, extension, abduction, and adduction Common in ball-and-socket joints
Special Movements Dorsiflexion Plantar flexionLifting the foot so that the superior surface approaches the shin Plantar flexion Depressing the foot (pointing the toes)
Special Movements Inversion Eversion Turn sole of foot mediallyTurn sole of foot laterally
Special Movements Supination PronationForearm rotates laterally so palm faces up (anterior) Pronation Forearm rotates medially so palm faces down (posterior)
Special Movements OppositionMove thumb to touch the tips of other fingers on the same hand

Movements at Synovial joints
Joint Movements Angular movements increase or decrease the angle between articulating bones. Flexion is a decrease in the angle. Extension is an increase.
