Muscle Insertion and Origins

supraspinatus

origin: supraspinous fossa of scapula insertion: greater tubercle of humerus

infraspinatus

origin: infraspinous fossa of scapula insertion: greater tubercle of humerus

subscapularis

origin: subscapular fossa of scapula insertion: lesser tubercle of humerus

teres minor

origin: lateral border of scapula insertion: greater tubercle of humerus

biceps brachii (short head)

origin: coracoid process of scapula insertion: radial tuberosity of radius

biceps brachii (long head)

origin: supraglenoid tubercle of scapula insertion: radial tuberosity of radius

brachialis

origin: distal anterior humerus insertion: ulnar tuberosity and coronoid process of ulna

brachioradialis

origin: superior to lateral epicondyle of humerus insertion: styloid process of radius

triceps brachii (lateral head)

origin: superior lateral humerus insertion: olecranon of ulna

triceps brachii (long head)

origin: infraglenoid tubercle of scapula insertion: olecranon of ulna

triceps brachii (medial head)

origin: posterior humerus insertion: olecranon of ulna

psoas major

origin: anterior surfaces and transverse processes of T12-L5 insertion: lesser trochanter of femur

rectus femoris

origin: anterior inferior iliac spine and acetabular rim of ilium insertion: tibial tuberosity

vastus intermedius

origin: anterolateral femur and line aspera insertion: tibial tuberosity

vastus lateralis

origin: inferior to greater trochanter of femur and proximal linea aspera insertion: tibial tuberosity

vastus medialis

origin: linea aspera of femur insertion: tibial tuberosity

biceps femoris

origin: ischial tuberosity and linea aspera of femur insertion: head of fibula, lateral condyle of tibia

semimembranosus

origin: ischial tuberosity insertion: medial condyle of tibia

semitendonosus

origin: ischial tuberosity insertion: medial surface of tibia

tibalis anterior

origin: lateral condyle and proximal shaft of tibia insertion: base of first metatarsal bone and medial cuneiform

gastocnemius

origin: femoral condyles insertion: calcaneus

soleus

origin: shafts of fibula and tibia insertion: calcaneus
