Muscle volume (A & B) and mean muscle fascicle length (C & D) for pelvic and thoracic limb muscles. Muscles are plotted starting with the proximal muscle with the largest mean volume/fascicle length and ending with the distal muscle with the smallest mean volume/fascicle length. Abbreviations for pelvic limb muscles are given in Tables 1 and 2. Thoracic limb muscle abbreviations are as follows: LOT (long head of triceps brachii), SVT (serratus ventralis thoracis), PP (pectoralis profundus), BO (brachiocephalicus and omotransversarius); SVC (serratus ventralis cervicis), LD (latissimus dorsi), PTD (pectoralis transvs. and pectoralis descendens), SC (subclavius), SS (supraspinatus), LAT (lateral head of triceps brachii), TP (trapezius), RC (rhomboideus cervicis), BBM (medial head of biceps brachii), RT (rhomboideus thoracis), BBL (lateral head of biceps brachii), MT (medial head of triceps brachii), ECR (extensor carpi radialis), DDFH (humeral head of flexor digitorum profundus), UL (ulnaris lateralis), CDE (extensor digitorum communis), FCU (flexor carpi ulnaris), SDF (flexor digitorum superficialis), FCR (flexor carpi radialis), DDFU (ulna head of flexor digitorum profundus), LDE (long digital extensor), DDFR (radial head of flexor digitorum profundus), APL (abductor pollicis longus).
