| Commonly named according to the bones or portions of the bones that are united at that location. | Joint |
| The ____ is located between the temporal bone and the mandible. | Temporomandibular Joint |
| Contain synovial fluid and allow considerable movement between articulating bones | Synovial joints |
| Synovial joints are often ____ more complex than the other types of joints. | Anatomically |
| Often exists as a thin layer of hyaline cartilage covering articular surfaces of synovial joints. | Articular cartilage |
| ____ are sometimes associated with several synovial joints; providing extra strength and depth to the joint cavity. | Articular disks |
| Consists of dense irregular connective tissue and portions of it may thicken to form ligaments. | Fibrous capsule |
| Some bursae may extend along tendons for some distance forming a ____ | Tendon sheath |
| A joint's ____ relates to the movements that occur at the joint. | Structure |
| Movement is best described in relation to ____ | Anatomical position |
| Most movements occur in ____ , one moving in a particular direction and one in the opposite direction | Pairs |
| Bending at the waist to one side or the other | Lateral flexion |
| Flexion/extension and abduction/adduction are the most common types | Angular movements |
| Rotation of a structure around an axis or movement in an arc | Circular movements |
| Movement away from the midline | Abduction |
| Movement toward the midline | Adduction |
| Moves part of the body in a posterior direction | Extension |
| Moves part of the body in an anterior direction | Flexion |
| Occurs in plant joints between two flat surfaces | Gliding movements |
| Rotation of forearm so that the palm faces up | Supination |
| Simplest type of all movements | Gliding movements |
| Standing on your toes | Plantar flexion |
