Verified step by step guidance1
Understand that muscle names often provide information about their function or location. For example, 'Flexor' indicates a muscle that flexes a joint, and 'Abductor' indicates a muscle that moves a limb away from the body's midline.
Analyze the name 'Flexor pollicis brevis': 'Flexor' suggests it flexes, 'pollicis' refers to the thumb, and 'brevis' indicates it is short.
Consider 'Abductor digiti minimi': 'Abductor' suggests it abducts, 'digiti' refers to a finger or toe, and 'minimi' indicates it is the smallest.
Examine 'Extensor carpi radialis longus': 'Extensor' suggests it extends, 'carpi' refers to the wrist, 'radialis' indicates it is near the radius bone, and 'longus' means it is long.
Review 'Transverse abdominis': This name does not indicate a specific action but rather describes the muscle's orientation ('transverse') and location ('abdominis' refers to the abdomen).
