external intercostals | inferior border of the rib above | superior border of rib below | contraction elevates the ribs and increases the anteroposterior and lateral dimensions of the thoracic cavity, resulting in inhalation; relaxation depresses the ribs and decrease the anteroposterior and lateral dimensions of the thoracic cavity, resulting | thoracic spinal nerves T2-T12 |
internal intercostals | superior border of rib below | inferior border of rib above | contraction draws adjacent ribs together to further decrease the anteroposterior and lateral dimensions of the thoracic cavity during forces exhalation | thoracic spinal nerves T2-T12 |
Adductor brevis | inferior ramus of pubis | superior half of linea aspera of femur | adducts and flexes thigh at hip and medially rotates thigh | Obturator nerve |
Adductor longus | pubic crest and pubic symphysis | linea aspera of femur | adducts and flexes thigh and laterally rotates thigh (longus:lateral) | Obturator nerve |
