bone to bone, which prevents excessive jt movement
Six types of synovial joints
Ball and socket (GH joint)
Ellipsoid (radiocarpal jt)
Hinge (humeroulnar jt)
Saddle (thumb)
Gliding (carpals or tarsals)
Pivot (1st & 2nd cervical vert)
Which type of synovial jt is this? Consists of oval-shaped end articulating with the elliptical basin of another bone. It permits flexion/extension and abduction/adduction.
Ellipsoid joint.
Which type of synovial jt is this? It allows for only flexion/extension. Example: elbow
Hinge joint
Which type of synovial jt is this? It's a modified ellipsoid jt composed of convex and concave articulating surfaces. Example- thumb
Saddle joint
Which type of synovial jt is this? It's usually between two flat surfaces and allows for the least movement- only small shifting movements.
Gliding jts
Which type of synovial jt is this? It's designed to allow one bone to rotate around the surface of another.
Pivot
First and second cervical vertebrae are an example of which joint type?
Pivot
Which type of synovial jt is this? Egg shaped head of bone articulates with cup shaped cavity of another.
Ball and socket
Why is the scapulothoracic "joint" not a real synovial joint?
The scapula is suspended on the rib cage by muscles
What movement is a bending that reduces the angle of a joint so that the parts come together within the sagittal plane?
Flexion
What is movement of a limb away from the midline within the coronal plane?
ABduction
What is the turning of the head/torso within the transverse plane?
Rotation
From anatomical position, the turning of a limb toward the midline within the transverse plane.
Internal/medial rotation
Movement of the scapula in an arc lateral and superior in relation to the humerus in the coronal plane
Upward rotation
Moving a part backward (scap or jaw)
Retraction
Moving a part forward (scap or jaw)
Protraction
Movement toward the midline within the transverse plane (shoulder joint)
Horizontal adduction
Moving a body part so that its end follows a circular path
