Question

Which of the following best represents the functional classifications of joints ranked from least movable to most movable?

a) Synarthroses, amphiarthroses, diarthroses
b) Diarthroses, amphiarthroses, synarthroses
c) Amphiarthroses, synarthroses, diarthroses
d) Diarthroses, synarthroses, amphiarthroses

Answer 1

The functional classifications of joints ranked from least movable to most movable are synarthroses (immovable), amphiarthroses (slightly movable), and diarthroses (freely movable). The correct order is Synarthroses, amphiarthroses, diarthroses.

Step-by-step explanation:

The functional classifications of joints ranked from least movable to most movable are as follows:

1. Synarthroses: These are immovable joints found in areas where movement between the bones is not necessary, such as the sutures between the skull bones.
2. Amphiarthroses: These joints allow for slight movement, such as the symphysis found in the vertebrae and the pubic symphysis in the pelvis.
3. Diarthroses: These are freely movable joints, which include all synovial joints like the elbow and shoulder, allowing for a large range of motion.

Therefore, the best representation of the functional classifications of joints ranked from least movable to most movable is a) Synarthroses, amphiarthroses, diarthroses.
