FUNCTIONAL CLASSIFICATION Joints are commonly classified on their functional characteristics, using the amount of movement allowed as the criterion. Functionally, joints may be called synarthroses, amphiarthroses, or diarthroses. Joints with a very tight union that allows no movement are synarthroses (syn = union + arthro = joint). They include sutures between the cranial bones and the joints between the teeth and their sockets. Joints allowing a limited movement are amphiarthroses (amphi = two sides), and include the intervertebral discs and the pubic symphysis. Joints that allow a large range of movement are known as diarthroses (di= apart). As you may suspect, they include the shoulder, elbow, knee, and most of the remaining joints of the body. Identifying Joints by Function You will review the functional classification of joints in this observational exercise. 1. Identify the functional category of the joints as synarthroses, amphiarthroses, or diarthroses by completing the labels in Figure 12.3. 1. diathroses 2. 3. 4. 5. 6. 7. 8. 9. 2. Using a model of an articulated skeleton or a chart from your lab, identify the joints as synarthroses, amphiarthoses, and diarthroses.

Table 9.2 Classification of synovial joints

Topic: Joints Synovial Joints are classified according to six different shapes. First, describe each type of joint shape, and then give example of where it can be found in the body.

The pectoralis major can do which of the following movements at the shoulder? Group of answer choices External rotation Horizontal adduction All of these Horizontal abduction

When evaluating a patient with a complaint of "twisting" the knee while playing sports.  What musculoskeletal maneuver would best evaluate any type of injury and why.  What is a positive vs negative exam.

What joints, in particular, occur in these planes and axis' during these ranges of motion? Shoulder Flexion (plane: sagittal, axis: frontal)    Shoulder Extension (plane: sagittal, axis: frontal)    Shoulder abduction (plane: frontal, axis: sagittal)    Shoulder Horizontal Abduction (plane: transverse, axis: vertical)

A score of 1 on the FMS shoulder mobility pattern is most likely not attributed to: Joint laxity Tightness of the latissimus Doris Rounded shoulders Overdevelopment of the pectoralis minor

Procedure 1 ldentifying Joint Motions of Common Movements Team up with a partner, and have your partner perform each of the following a actions are performed, and list the joints that are in motion ctions. Watch carefully as the for each joint (e.g., anual/ Ask your instructor if he or she wants you to use the technical name or the common name ious. Others, such be obv glenohumeral versus shoulder joint). Some of the joints, such as the hip joint and knee joint, will as the radio ulnar joint, the interphala ngeal joints, and the intervertebral joints, are less obvious and easily overlooked. ised, determine which motions are occurring at each joint. Keep in mind the leted the activity, answer ction Once you have listed the joints being motions are type and the range of motion of each joint as you answer each question.
