All synovial joints are

• amphiartroses.

• diarthroses.

• synartroses.

• synchondroses.

ball and socket joints

• elbow and knee

• hip and shoulder

• intercarpal and intertarsal

• radioulnar and carpometacarpal

Type of joint that is non-moving

• Synarthrosis

• Amphiarthrosis

• Diarthrosis

• Gliding

Type of joint that is slightly moving?

• Amphiarthrosis

• Synarthrosis

• Diarthrosis

• Fixed

Type of joint that is freely moving?

• Amphiarthrosis

• Diarthrosis

• Synarthrosis

Bending that goes beyond the anatomical position

• Hyperextension

• Flexion/Extension

• Rotation

• Opposition

Flexion/Extension

• Flexion is bending decreases the angle of the joint; extension is straightening.

• Flexion is a type of muscle contraction; extension is relaxation.
• Flexion is straightening; extension is bending.
• Flexion and extension are the same movements.

Supination/Pronation

• Supination is outward/forward rolling; Pronation is inward/backward rolling.

• Supination is a term used for flexing the wrist; Pronation is for extending the wrist.
• Supination and Pronation both refer to the same motion.
• Supination is inward rolling; Pronation is outward rolling.

Circumduction

• Circumduction is a circular movement of a limb.
• Circumduction is a type of stretching exercise.
• Circumduction refers to the rotation of the torso.
• Circumduction is a linear movement of a limb.

Match the structural classification of joints to their definition.

• Cartilaginous

• connect with cartilage, therefore rigid but slightly movable

• Fibrous

• connect with dense connective tissues AND a fluid filled joint, therefore allows the most movement

• synovial

•  connect with collagen fibers, therefore mostly immovable
