NSC 832 Musculoskeletal System Questions and Correct
Answers |Already Graded A+||Brand New Version!!!
What are articular structures - CORRECT ANSWER -joint capsule, articular cartilage,
synovium, synovial fluid, intra-articular ligaments, juxta-articular bone
What are extra-articular structures - CORRECT ANSWER -periarticular ligaments, tendons,
bursae, muscle, fascia, bone, nerve, overlying skin
What are ligaments - CORRECT ANSWER -Ropelike bundles of collagen fibrils that connect
bone to bone
What are tendons - CORRECT ANSWER -Collagen fibers connecting muscle to bone
What is cartilage - CORRECT ANSWER -Collagent matrix overlying bony surface
What is bursae - CORRECT ANSWER -Pouches of synovial fluid that cushion the movement of
tendons and muscles of bone or other joint structures
What is a synovial joint - CORRECT ANSWER -A freely movable joint surrounded by a joint
capsule (eg shoulder, knee)
What is a cartilaginous joint - CORRECT ANSWER -It allows slight movement and it is near the
ends of a bone. An example would be the manubrium and the sternum or vertebral bodies of the
spine; bones separated by fibrocartilaginous discs
What is a fibrous joint - CORRECT ANSWER -immovable joint; bones separated by fibrous
tissue or cartilage (eg skull)
, what are bones covered by - CORRECT ANSWER -articular cartilage
What are bones separated by - CORRECT ANSWER -Synovial cavity (bones do not touch)
What do synovial membranes do - CORRECT ANSWER -1. secrete synovial fluid into the joint
cavity
2. lubricates the ends of of bones so they move freely
What is a spheroidal synovial joint - CORRECT ANSWER -Ball and socket, very mobile (eg
shoulder, hip)
What is a hinge synovial joint - CORRECT ANSWER -One plane, movement more limited
(forward or backwards or flexion and extension) eg elbow and digits
What is a condylar synovial joint - CORRECT ANSWER -Articulating surfaces are convex or
concave; eg knee, TMJ; have condyles or convex surface
What kind of joint is the knee - CORRECT ANSWER -In structure it is a condylar joint (rotates
in multiple directions when there is an ACL or MCL tear) but in function it is a hinge joint
(because of the ligaments holding it stable
What cushions bones movement in discs - CORRECT ANSWER -Nucleus pulposus
What is lordosis - CORRECT ANSWER -Swayback in the lumbar region (butt sticks out); can
be from being pregnancy, overweight or having too much weight anteriorly; spine is in
What is kyphosis - CORRECT ANSWER -Spine curves out (humpback)
What is scoliosis - CORRECT ANSWER -Spine asymmetry
