Fibrous Joints
True or False: joints in this category may be connected by ligaments or interosseous membranes.
True
Which type of cartilaginous joint would be considered synarthrotic?
synchondrosis joints
Which type of joint provides the widest degree of motion (multiaxial)?
ball & socket joints
Where in the body (axial or appendicular) would you expect to find synovial joints?
This movement decreases the angle of a joint, such as bending the elbow or knee.
What is flexion?
What is the name of the joints that connect the plates of the skull together, replacing the fontanels during infancy.
sutures
Which type of cartilaginous joint would be considered amphiarthrotic?
Symphysis Joints
Which type of joint is considered uniaxial?
pivot joint (atlas & axis of skull and vertebral column)
What is the term used to describe freely moveable joints?
synovial joints
This type of movement moves a limb away from the midline of the body, like raising your arm to the side.
What is abduction?
What 2 bones of the AXIAL skeleton are connected by this type of joint?
tibia and fibula
Which of these joints would be located exclusively in the thoracic cavity?
1st Sternocostal Joint (1st rib + manubrium of the sternum)
This type of synovial joint permits sliding or gliding movements, such as between the wrist bones.
What is a gliding (plane) joint?
What is the term used to describe partially moveable joints?
amphiarthrosis
This movement describes a circular motion that combines flexion, extension, abduction, and adduction.
What is circumduction?
What 2 bones of the APPENDICULAR skeleton are connected by this type of joint?
radius and ulna
Which type of these joints will be located in long bones?
epiphysial plates between the epiphysis and diaphysis
These strong connective tissue bands connect bone to bone and help stabilize synovial joints.
What are ligaments?
What is the term used to describe immovable joints?
synarthrosis
This forearm movement turns the palm upward, as if holding a bowl of soup.
What is supination?
What is the name of the joint that connects the tooth to the mandible/maxilla via the periodontal ligament?
gomphosis
Which category of cartilaginous joints would be amphiarthrotic AND WHY (must name one of the 2 joints we discussed in class)?
symphysis joints b/c we need to twist and bend our bodies (vertebral discs) and babies/moms need an easier childbirth experience (pubic symphysis)!!!!!
This synovial joint allows movement in two planes, such as flexion/extension and abduction/adduction, as seen in the wrist.
What is a condyloid (ellipsoidal) joint?
What is the order of functional joint classification from least to most mobile.
synarthrosis, amphiarthrosis, diarthrosis
This movement turns the sole of the foot inward toward the midline of the body.
What is inversion?
