List four types of joints based on the way they adjacent bones are joined - Correct Answer -1 Bony
2 Fibrous
3 Cartilaginous
4 Synovial joints
Explain the discrepancy between the number of bones in infants and adults - Correct Answer -2 bones,
once separate, fused by osseous tissue
Ossification occurs with age
frontal and mandibular bones in infants
cranial sutures in elderly
attachment of first rib and sternum with old age
List and describe the three types of fibrous joints - give examples of each - Correct Answer -three kinds
of fibrous joints
sutures - synarthroses
gomphases - synarthroses
syndemoses - synarthroses

,serrate - Correct Answer --interlocking wavy lines, coronal, sagittal ,lambdoid
lap (squamous) - Correct Answer --overlapping beveled edges, temporal and parietal bones, squamous
suture
plane(butt)- - Correct Answer -straight, nonoverlapping edges
palatine processes of the maxillae,Intermaxillary suture
Define interosseous membrane and name their locations in the body - Correct Answer -Interosseus
membranes unite -radius to ulna(allowing pronation and supination ;there is some debate as to whether
or not this is a amphiarthrosis)
-tibia to fibula(limited movement)
synchondroses-cartilaginous joints - Correct Answer -- bound by hyaline cartilage (first rib attach to
sternum)
symphyses-cartilaginous joints - Correct Answer --two bones joined by fibrocartilage (pubic symphasis)

, Explain the significance of synovial joints - Correct Answer --joint in which two bones are separated by a
space called a joint cavity
-diarthroses or diarthrodial joints
-most familiar type of joint
-most are freely movable
-most structurally complex type of joint
-most likely to develop painful dysfunction
-most important joints for physical and occupational therapists, athletic coaches, nurses, and fitness
trainers
-their mobility make them important to quality of life
Draw and label a synovial joint - include functions of the structures - Correct Answer --articular cartilage
-hyaline cartilage that covers the facing surfaces of bones
-Joint (articular) cavity - separates articular surfaces
-synovial- slippery lubricant, rich in albumin and hyaluronic acid; viscous, slippery texture like raw egg
whites; nourishes articular cartilage &removes waste; makes movement almost friction free
-Joint (articular) capsule - connective tissue that encloses the cavity & retains synovial fluid
-outer fibrous capsule - continuous with periosteum of adjoining bones
Describe fibrocartilage that is associated with synovial joints - Correct Answer -Fibrocartilage grows
inward from the joint capsule in a few synovial joints
-articular disc-forms a pad between articulating bones that crosses the entire joint capsule;
temporomandibular joint, distal radioulnar joints, sternoclavicular & acromioclavicular joints
