Flexor digiti minimi brevis The insertion is the base of proximal phalanx of fifth toe. Dorsal interossei The nerve innervation is tibial S1, 2. Abdominals These muscles have no bones in their area because these organs need room to function. Abductor digiti minimi Despite its name, this muscle is stronger in flexion rather than abduction of the little toe. Rhomboid major The muscle adducts the scapula.

Pectoralis major The origin is the medial half of clavicle, sternum, and cartilage of first through sixth ribs. External oblique This muscle got its name because it's the most superficial muscle of the abdomen and its fibers run in a diagonal direction. Extensor digitorum longus The insertion is the middle and distal phalanges of second through fifth toes. Popliteus This muscle is often called "the key to the knee" because it is crucial for unlocking the knee joint at the beginning of flexion. Abductor Pollicis Longus The nerve innervation is Radial C6, 7, 8. Tibialis posterior The origin is the proximal, posterior shafts of tibia and fibula; and interosseous membrane. Levator Scapula This muscle is often referred to as a "trigger point" muscle. It can be a common culprit for headaches when tight or strained. Frontalis This muscle is part of a pair. With the other half on the opposite side of the face. Fibularis brevis The insertion is the tuberosity of fifth metatarsal.
