What are joints also known as? - ANSWER-Articulations
What are the 3 major functions of joints? - 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? - ANSWER-By how adjacent bones are joined
Joints can be identified as either structural or functional. How are joints FUNCTIONALLY
classified? - ANSWER-By the degree of movement that they allow
What are the 3 STRUCTURAL classifications of joints? - ANSWER-1) Fibrous
2) Cartilaginous
3) Synovial
What is a fibrous joint? - ANSWER-A joint that is made of dense connective tissue
- Made for ANCHORING
What is a cartilaginous joint? - ANSWER-A joint that is made of cartilage
What is a synovial joint? - ANSWER-A joint that is made of a fluid-filled membranous capsule
What are the 3 FUNCTIONAL classifications of joints? - ANSWER-1) Synarthroses
2) Amphiarthroses
3) Diarthroses
What is a synarthroses joint? - ANSWER-A joint that allows NO movement (immovable)
What is an amphiarthroses joint? - ANSWER-A joint that allows SLIGHT movement (slightly
movable)
What is a diarthroses joint? - ANSWER-A joint that allows FREE movement (freely movable)
, Fibrous joints can only be either synarthrotic or amphiarthrotic. Why? - 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. - 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? - ANSWER-Found in the skull;
they bind skull bones together (immovable)
Types:
- Serrate: interlocking articulations; ex: sagittal suture
- Lap: bone overlaps bone; ex: squamous suture
- Plane: edges of articulating bones are smooth; ex: maxillary suture
Gomphoses is a type of fibrous joints. Where are gomphoses found? - ANSWER-ONLY found
attaching teeth to its sockets (immovable)
- Teeth held in place by fibrous periodontal ligaments
Syndesmose are a type of fibrous joints. Where are syndesmose found? - ANSWER-Found in the
membrane between the tibia and fibula (slightly movable)
- Bones bound by interosseus membrane
Cartilaginous joints can only be either synarthrotic or amphiarthrotic (like fibrous joints). Why? -
ANSWER-Just like collagen fibers in fibrous joints, cartilage spans between adjacent bones,
causing LITTLE to NO MOVEMENT
What are the 2 types of cartilaginous joints? Determine whether they're synarthrotic or
amphiarthrotic. - ANSWER-1) Synchondrose (immovable/synarthrotic_
2) Symphyses (slightly movable/amphiarthrotic)
