Question 9 (1 point)
Match the muscle with the number of joints MOVED by that muscle.
Do not consider the carpals or tarsals a joint for this question. Also, if the muscle cross a joint, but that muscle does not move that joint, or that joint barely moves - do not count it.
For instance, the pectoralis major muscle crosses from the upper thorax to the humerus, so it crosses the glenoid-humeral joint, right? Well it also crosses the acromo-clavicular(AC) joint and the sterno-clavicular (SC) joint, but since the AC joint barely moves and the SC joint does not move much at all when the pec major muscle contracts, do not consider either of these in your total count.
However, if that muscle moves many joints, but only moves each of those joints to a small degree, such as rectus abdominus, which moves most of the thoracic vertebral column, consider that muscle to move multiple joints
Question 9 options:
123 Iliopsoas
123 Adductor Magnus
123 Sternocleidomastoid
123 Coracobrachialis
123 Rectus Abdominus
123 Pronator Quadratus (consider the distal and proximal radioulnar joint to be the same)
123 Deltoid
123 Teres Minor
123 Biceps Femoris
123 Biceps Brachii
1. Moves ONE joint
2. Moves TWO or more joints
3. Moves NO joints
