– Pivot joint.
– Rotation: Limb moves in a circular movement towards the middle
of the body.
– Flexion: Occurs when the angle of a joint decreases.
– Extension: Occurs the angle of a joint increases.
– Lateral flexion & extension.

– Ball & Socket joint.
– Circumduction: limb moves in a circle.
– Rotation.
– Abduction: Movement away from the midline of the body.
– Adduction: Movement towards the midline of the body.
– Horizontal adduction & abduction.
– Flexion.
– Extension.
– Hyperextension: exaggerated extension motion.

– Synovial hinge joint.
(Specific to ankle joint)
– Plantarflexion: Foot moves away from the shin bone, and your
toes will be pointing downward.
– Dorsiflexion: foot moves toward the shin bone as if you are
pulling your toes up.
– Occurs at gliding joint between tarsals:
– Inversion: Soles of the feet are facing each other.
– Eversion: Soles of the feet are facing away from each other.

• Tendons:
– Connects muscle to bone.
– Carry force of muscle
contraction to the bone.
• Ligaments:
– Connects bone to bone.
– Act to give stability to
joints.
12
• Cartilage: Tough, fibrous connective tissue without
nerves or blood supply that provides protection and
support to joints, tubes, ends of long bones, and facial
structures (e.g., ears and nose).
13
• Bursa: small sacs of fluid that are located between
bone & other moving structures i.e. muscles, skin,
tendons.
Bursa
allows
smooth
gliding
between
structures, without friction.
