Q

Which ligament of the sternoclavicular joint can a branch of the brachial plexus be caught under, causing pain and muscle weakness?

  1. Supraclavicular ligament
  2. Sternoclavicular ligament
  3. Interclavicular ligament
  4. Costoclavicular ligament
A

Costoclavicular ligament. Dislocations of this joint are not common but posterior dislocation can result in damage to the brachiocephalic veins that are located posterior to it.

  1. Nerve to the subclavius
  2. Supraclavicular
  3. Brachiocephalic
A

Q

What type of joint is the acromioclavicular joint?

  1. Pivot
  2. Ball and Socket
  3. Saddle
  4. Planar
A

Planar. The main function of the joint is to bind the clavicle to the scapula in order to support the weight of the upper limb and keep the humerus suspended at the side. Shoulder separation occurs at this joint
