Answer 24

synchondroses (cartilaginous)

Question 25

intervertebral discs, back, pubic symphysis, fortified by strong fibrocartilage, joints are usually midline in position and supportive (rigid)

Answer 25

symphoses (cartilaginous)

Question 26

all joints are encapsulated and contains synovial fluids, may be classified as either nonaxial, uniaxial, biaxial, or multiaxial
