joints

Question 1

name the structural classification of joints

Answer 1

fibrous, cartilaginous, synovial

Question 2

name the functional classification of joints

Answer 2

synarthrosis, amphiarthrosis, diarthrosis

Question 3

name the types of synovial joints

Answer 3

plane, hinge, pivot, saddle, condyloid, ball and socket

Question 4

describe the movements allowed at each synovial type and an example

Answer 4

plane - non axial, gliding, intercarpals
hinge - uniaxial, flexion and extension, knee and elbow
pivot, uniaxial, rotation, proximal radioulnar
saddle - biaxial, flexion/extension, adduction/abduction, thumbs
condyloid - biaxial - flexion/extension, adduction/abduction, wrist, knuckle
ball and socket - multiaxial, all movements, hip and shoulder

Question 5

describe the types of fibrous joints and an example

Answer 5

suture - skull (synarthrosis)
syndesmosis - tibia and fibula (amphiarthrosis)
gomphosis - teeth (synarthrosis)

Question 6

describe the types of cartilaginous joints and an example

Answer 6

primary cartilaginous (synchondrosis) contains hyaline cartilage, found in epiphyseal plates, synarthrosis

secondary cartilaginous (symphisis)
contains fibrocartilage, found in vertebrae and pubic symphisis, amphiarthrosis
