Functional classification of joints is based on ________.
the amount of movement allowed by the joint
the location of the joint
whether a joint cavity is present
the size of the joint
answer
the amount of movement allowed by the joint
question
Which of the following does NOT represent a structural classification of joints?
cartilaginous
synovial
fibrous
diarthrosis
answer
diarthrosis
question
Which of the following refers to a joint that is immovable?
synarthrosis
diarthrosis
synovial
amphiarthrosis
answer
synarthrosis
question
Which of the following are CORRECTLY paired?
synchondrosis: a plate of hyaline cartilage unites the bones
suture: bones connected exclusively by ligaments
syndesmoses: bony edges interlock
gomphoses: articulating bones are separated by a fluid containing cavity
answer
A synchondrosis is a plate of hyaline cartilage that unites the bones. Epiphyseal plates are examples of synchondroses.
question
Using the structural classification, what type of joint is the epiphyseal plate?
synarthrotic joint
fibrous joint
amphiarthrotic joint
cartilaginous joint
answer
The epiphyseal plate is a cartilaginous joint-a hyaline cartilage "growth plate" between the epiphysis and diaphysis of a long bone

question
Which joint has sacrificed stability to provide great freedom of movement?
elbow
ankle
shoulder
knee
answer
shoulder
question
Which of the following represents a correct statement about multi axial joints?
The shapes of articulating surfaces in the multiaxial joint are a cylindrical bone in a trough.
Movement in more than two axes is permitted in a multi axial joint.
The rounded end of the proximal metacarpal fitting into the distal surface of the carpal bone of the wrist is a classic ball-and-socket joint.
The ball-and-socket joint permits only one angular motion.
answer
Movement in more than two axes is permitted in a multiaxial joint.
