Understanding Joints and Movements

Which type of joint is the shoulder joint classified as?

• Pivot joint

• Condyloid joint

• Ball and socket joint

• Hinge joint

What bones form the hinge joint at the elbow?

• Radius, ulna, and carpals

• Femur, tibia, and fibula

• Humerus, radius, and ulna

• Clavicle, scapula, and humerus

What is the primary movement that decreases the joint angle?

• Abduction

• Rotation

• Flexion

• Extension

Which movement involves pointing the toes upwards?

• Hyperextension

• Lateral flexion

• Dorsiflexion

• Plantar flexion

What does hyperextension refer to?

• A joint angle increasing

• A joint moving sideways

• A joint angle decreasing

• A joint angle moving past 180 degrees

What is lateral flexion?

• Decreasing a joint angle sideways

• Rotating a limb around an axis

• Moving a limb away from the midline

• Increasing a joint angle

What does abduction involve?

• Flexing a joint

• Rotating a limb

• Moving a limb away from the midline

• Moving a limb towards the midline

How is circumduction different from rotation?

• It is a type of flexion

• It involves a fixed axis

• It describes a circular motion

• It only occurs in the hip

What is horizontal flexion?

• Moving a limb away from the midline in a horizontal plane

• Decreasing the angle between the humerus and torso in a horizontal plane

• Increasing the angle between the humerus and torso in a horizontal plane

• Rotating a limb in a horizontal plane

What is horizontal abduction?

• Moving a limb away from the midline in a horizontal plane

• Decreasing the angle between the humerus and torso

• Moving a limb towards the midline in a horizontal plane

• Increasing the angle between the humerus and torso
