Identify the location of following structures on a live body: sternocleidomastoid tendon of extensor digitorum pectoralis major gluteus maximus deltoid hamstrings biceps brachii quadriceps femoris triceps brachii tibialis anterior tendon of flexor carpi radialis gastrocnemius 6. Identify the following muscles in the body builder photographs available during lab: trapezius serratus anterior pectoralis major teres major latissimus dorsi deltoid external oblique rectus abdominis biceps brachii gluteus maximus gracilis sartorius rectus femoris vastus lateralis vastus medialis gastrocnemius sternocleidomastoid hamstrings triceps brachii
