Semester/session grade-point average and cumulative grade-point average are calculated to represent numerically a student's quality of performance. These averages are used to determine if a student qualifies for certain academic actions (e.g., Dean's List, academic warning/drop, entrance to and changes in college/major, and graduation) and programs (e.g., student aid and study abroad). Grades and Grade-Point Equivalents. Semester/Session Grade-Point Average.
Another example of an amphiarthrosis is the pubic symphysis of the pelvis. This is a cartilaginous joint in which the pubic regions of the right and left hip bones are strongly anchored to each other by fibrocartilage. This joint normally has very little mobility.
There are many different classes of synovial joints in the body, including gliding, hinge, saddle, and ball and socket joints. 1  Gliding joints, such as the ones between the carpals of the wrist, are found where bones meet as flat surfaces and allow for the bones to glide past one another in any direction. An amphiarthrosis allows a slight amount of movement at the joint. 2  Examples of amphiarthroses include the intervertebral disks of the spine and the pubic symphysis of the hips. 3  The third functional class of joints is the freely movable diarthrosis joints.
