The cuboid-metatarsal joint is a joint that connects the cuboid bone to the metatarsals, and is not generally considered part of the three major ankle joints. Instead, it is generally classified as a joint in the foot.

There are two different coronary ligaments in the body. The coronary ligament of the liver serves to connect the liver to the inferior surface of the diaphragm; as this is not an answer option, we must be looking at the second type of coronary ligament.
The coronary ligament of the knee serves to connect the menisci to the tibial condyles, and is continuous with the joint capsule of the knee.

These are all types of synovial joints, defined by their apparent shapes and mechanisms of motion. For example, the knee is a hinge joint, which allows flexion and extension along a single axis, but not adduction or rotation.

Ginglymus joints are also known as hinge joints, which only permit flexion/extension movements. The humeroulnar joint of the elbow is the best example of this. Cotyloid and ball and socket joints are synonymous, and permit motion in all three planes. Pivot joints and lateral ginglymus are synonymous, and permite transverse plane movement.

The shoulder, similar to the hip is formed by a ball-and-socket joint. The ball is created by the head of the humerus, while the socket is created by the glenoid cavity. This creates a smaller, less stable version of the ball-and-socket joint in the hip

In which direction is a shoulder dislocation most likely to occur?
In which direction is a shoulder dislocation most likely to occur?
Tap to see back →
A shoulder dislocation occurs when the humeral head is removed from the glenoid fossa. The clavicle and coracoacromial ligament are located superior to the joint, preventing superior dislocation, and the body o the scapula is posterior to the joint, preventing posterior dislocation. Most commonly, the humeral head is pushed forward and downward. There is the least resistance to dislocation in the anterior and inferior directions; though glenohumeral dislocation can occur in other orientations, these are far less common.

Which upper extremity nerve is at risk of injury after dislocation of the shoulder?
Which upper extremity nerve is at risk of injury after dislocation of the shoulder?
Tap to see back →
The axillary nerve travels through the quadrangular space with the posterior circumflex humeral artery, and can be damaged due to trauma of the upper extremity, particularly anterior-inferior shoulder dislocations. When the dislocation is reduced, placement of the humeral head can displace or damage the nerve if done improperly.

Often in physiology, joints are described by three characteristics: their functional class, which describes the degree of mobility the joint affords; their structural class,which describes how the joint is housed; and their shape.

The joints between the metacarpals and phalanges in the hand are classified as diarthrosis (allows full motion), synovial (encased in a capsule filled with synovial fluid, true of all diarthrosis joints by default), and condyloid (ovoid in shape, sometimes received into an elliptical cavity).

Joints are often named for the two bones they connect, but sometimes bear common alternate names that give no such indication.

The subtalar joint, also called the talocalcaneal joint, is a condyloid (plane synovial) joint that allows for the inversion/eversion mechanism of the foot, but not dorsiflexion or plantarflexion. It is sometimes combined with the navicular joint to form the talocalcaneonavicular joint when considering the motion of the whole ankle.

The ulna is not part of the radiocarpal joint—if it were, the forces acting on the joint would prevent proper flexion and extension, limiting hand mobility and causing excessive damage from counterforces caused by the radius. Instead, a thin fibrocartiliginous ligament called the articular disk sits between the distal end of the ulna and the radiocarpal joint, allowing for a smooth, concave surface on the proximal side of the joint.

The glenoid cavity of the scapula is the place of articulation between the scapula and the humerus. The acromion and coracoid process are not sites of joint articulation and the olecranon is not found on the scapula, but on the ulna.

The radiohumeral joint of the elbow is formed by the articulation between the head of the radius, and the capitellum of the humerus. While the trochlea of the humerus, and the olecranon fossa do form part of the elbow, they articulate with the ulna. The scaphoid does articulate with the raidius, but at the distal end of the bone.

The elbow is a hinge joint, as it is only about to move in one plane of motion. The thumb is a saddle joint as it can move in multiple directions. The bones of the wrist are gliding joints as they are two flat surfaces moving over each other. Lastly, the shoulder is an example of ball and socket as it has a very wide range of motion.

The sternoclavicular and acromioclavicular joints link two bones of the pectoral girdle to each other and to the trunk of the body. They also combine their movements to increase reach length of the upper limb. They are both synovial joints and surrounded by a joint capsule with numerous ligaments to reinforce their movements. The glenohumeral joint serves in articulation of the humerus and scapula. The Sternohumeral joint does not exist.

The zona orbicularis is a portion of the joint capsule of the acetabulofemoral (hip) joint. It is thought to resist distraction (pulling out) of the femur. Additionally, it is believed to help circulate synovial fluid in the joint. As you may recall, synovial fluid helps lubricate joints and provides nutrition to their articular cartilage.

The rectus femoris, specifically the reflected head, attaches to the anterosuperior portion of the hip capsule. The gluteus minimus attaches to the superolateral portion of the capsule. Although its contribution to the capsule is relatively small, the obturator externus attaches to the posteroinferior joint capsule. Despite contributing to dynamic hip stability by eccentrically controlling hip internal rotation, the piriformis does not attach to the hip's joint capsule.

The rib bones do not directly interface with the sternum, but are linked to the sternum by regions of hyaline cartilage. The interface between the rib and the cartilage is a costochonral joint. The interface between the cartilage and the sternum is a sternocostal joint. Sternocostal joints are slightly articular synovial joints.

The thorax has three major articulations: sternoclavicular, sternocostal, and costochondral joints. The sternoclavicular provides a connection between the upper limbs and the axial skeleton, joining the manubrium of the sternum to the medial end of the clavicle. The sternocostal joints are the attachments between the sternum and the cartilage of ribs 1 to 7. Costochondral joints are the attachments of the ribs to their costal cartilages.
The acromioclavicular joint is formed between the acromion process of the scapula and the distal end of the clavicle. It is local to the shoulder, and is not found in the thoracic cavity.
