Rheuma Flashcards
Articular Structures
Joint capsule and articular cartilage
Synovium and synovial fluid
Intra-articular ligaments
Juxta-articular bone
Extra Articular Structures
Periarticular ligaments Tendons Bursae Muscle Fascia Bone Nerve Overlying skin
Are ropelike bundles of collagen fibrils that connect bone to bone
Ligaments
→ Are collagen fibers connecting muscle to bone
→ Another type of collagen matrix forms the cartilage that overlies bony surfaces
Tendons
Are pouches of synovial fluid that cushion the movement of tendons and muscle over bone or other joint structures
Bursae
Inflammation of a joint

How to locate and palpate the TMJ?
To locate and palpate the joint, place the tips of your index fingers just in front of the tragus of each ear and ask the patient to open his or her mouth.
→ externally at the angle of the mandible
Masseters
→ externally during clenching and relaxation of the jaw
Temporal muscles
→ internally between the tonsillar pillars at the mandible

Range of Motion: TMJ
glide (upper) and hinge motion (lower)
Chewing primarily _____ movement?
Chewing primarily gliding movement in the upper compartment
Normally as the mouth is opened wide, _____ fingers can be inserted between incisors.

coracoid process is part of the?
scapula
where the SITS muscles are inserted.
greater tubercle
Palpate the biceps tendon in the?

→ Supraspinatus
– posterior to supraspinatus
→ Infraspinatus
– posterior and inferior to the supraspinatus

The six motions of the shoulder girdle:
→ Flexion → Extension → Abduction → Adduction → Internal Rotation → External Rotation
―Raise your arms in front of you and overhead
Flexion
Raise your arms behind you
Extension
Raise your arms out to the side and overhead
Abduction
Glenohumeral motion
-patient should raise the arms to shoulder level at 90 degrees, with palms facing down
Scapulothoracic motion
-patient should turn the palms up and raise the arms an additional 60 degrees.
Cross your arm in front of your body
Adduction
Place one hand behind your back and touch your shoulder blade
Internal rotation
Identify the highest midline spinous process the patient is able to reach.
Raise your arm to shoulder level; bend your elbow and rotate your forearm toward the ceiling
External rotation
Place one hand behind your neck or head as if you are brushing your hair
