Musculoskeletal System Flashcards
____ include joint capsule and articular cartilage, synovium and synovial fluid, intra-articular ligaments, and juxta-articular bone
Articular structures
____ include periarticular ligaments, tendons, bursae, muscle, fascia, bone, nerve, and overlying skin
Extra-articular structures
ropelike bundles of collagen fibrils that connect bone to bone
Ligaments
collagen fibers connecting muscle to bone
Tendons
collagen matrix overlying bony surfaces
Cartilage
pouches of synovial fluid that cushion the movement of tendons and muscles over bone or other joint structures
Bursae
Characteristics of a synovial joint
- Joint is freely movable
- Bones are covered by articular cartilage
- Bones are separated by synovial cavity
- Synovial membrane secretes synovial fluid that lubricates joint movement
Examples: shoulder, knee
Characteristics of a cartilaginous joint
- Joint is slightly movable
- Bones separated by fibrocartilaginous discs
- Discs contain nucleus pulposus that cushions bony movement
Examples: vertebral
bodies of the spine
Characteristics of fibrous joints
- Joints have no appreciable movement
- Bones separated by fibrous tissue or cartilage
Example: sutures of
the skull
Types of joints
Spheroidal (ball and socket) - shoulder, hip
Hinge - interphalangeal joints of hand and foot, elbow
Condylar - knee, temporomandibular joint
When assessing joint pain, Determine whether the pain is
Localized or diffuse
Acute or chronic
Inflammatory or noninflammatory
Clarify and record the ____, particularly if the joint pain is caused by trauma
mechanism of injury
___ cervical, __ thoracic, and __ lumbar vertebrae are stacked on the sacrum and coccyx
7, 12, and 5
Two phases of Gait
Swing (foot moves forward, non-weight bearing) and stance (foot on ground, weight bearing)
Bursas to palpate on the knee
Over the suprapatellar bursa above the knee
Prepatellar bursa over the patella
Pes anserine bursa on posteromedial knee
