BIOL 2457: JOINTS QUESTIONS WITH
CORRECT ANSWERS 2025/2026
What are joints also known as? CORRECT ANSWER Articulations
What are the 3 major functions of joints? CORRECT ANSWER 1) Binds bones together
2) Allow bone growth
3) Enables the body to move in response to skeletal muscle contraction
Joint can be identified as either structural or functional. How are joints STRUCTURALLY
classified? CORRECT ANSWER By how adjacent bones are joined
Joints can be identified as either structural or functional. How are joints FUNCTIONALLY
classified? CORRECT ANSWER By the degree of movement that they allow
What are the 3 STRUCTURAL classifications of joints? CORRECT ANSWER 1) Fibrous
2) Cartilaginous
3) Synovial
What is a fibrous joint? CORRECT ANSWER A joint that is made of dense connective tissue
- Made for ANCHORING
What is a cartilaginous joint? CORRECT ANSWER A joint that is made of cartilage
What is a synovial joint? CORRECT ANSWER A joint that is made of a fluid-filled membranous
capsule
, What are the 3 FUNCTIONAL classifications of joints? CORRECT ANSWER 1) Synarthroses
2) Amphiarthroses
3) Diarthroses
What is a synarthroses joint? CORRECT ANSWER A joint that allows NO movement
(immovable)
What is an amphiarthroses joint? CORRECT ANSWER A joint that allows SLIGHT movement
(slightly movable)
What is a diarthroses joint? CORRECT ANSWER A joint that allows FREE movement (freely
movable)
Fibrous joints can only be either synarthrotic or amphiarthrotic. Why? CORRECT ANSWER
The collagen fibers inside of the dense connective tissue (what fibrous joints are made of) span
between adjacent bones. This allow LITTLE to NO MOVEMENT
What are the 3 types of fibrous joints? Determine whether they're synarthrotic or
amphiarthrotic. CORRECT ANSWER 1) Sutures (immovable/synarthrotic)
2) Gomphoses (immovable/synarthrotic)
3) Syndesmose (slightly movable/amphiarthrotic)
Sutures are a type of fibrous joints. Where are sutures found? CORRECT ANSWER Found in the
skull; they bind skull bones together (immovable)
Types:
- Serrate: interlocking articulations; ex: sagittal suture
