BI 234 - JOINTS EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED
Joint definition
a place where two bones connect
synarthrosis
-no movement
-bony, fibrous, cartilaginous
amphiarthrosis
-little movement
-fibrous, cartilaginous
diarthrosis
-freely moveable
-synovial
types of tissues involved between two bones
bone (bony), connective tissue (fibrous), fibrocartilage (cartilage), synovial capsule
(synovial)
structural features of a synovial joint (6)
-Articular cartilage
-joint cavity
-synovial fluid
-articular capsule
, -synovial membrane
-fibrous capsule
accessory structures of a synovial joint (5)
-Tendons (support joint)
-fat pads (protect cartilages)
-ligaments (intrinsic & extrinsic - support and strengthen joint)
-cartilages (cushion joint)
-bursae (cushion joint and reduce friction)
what structures stabilize a joint
Tendons (muscles), ligaments, skeletal elements
what is synovial fluid
Fluid found in joint cavity that lubricates, distributes nutrients, and acts as a shock
absorber
tissue types associated with joints (4)
-Hyaline cartilage (smooth for articular cartilage gliding)
-dense irregular connective tissue (for tough, fibrous capsule)
-dense regular connective tissue (tendons and ligaments resist forces in one direction)
-areolar connective tissue (produces fluid from the synovial membrane)
why does cartilage heal slowly
it is avascular & therefore does not get adequate nutrients to heal tissue damage easily
joint between the flat bones of the skull
Synarthrosis; fibrous; flat bones of skull (parietal, occipital, frontal, temporal); suture; no
movement
