Muscles that do lateral rotation of the arm at the shoulder
Trapezius
Deltoid
Infraspinatus
Teres minor
Origin and insertions for the muscles that flex the forearm at the elbow
Biceps brachii:
O = Long head: Supraglenoid tubercle of scapula. Short head: Coracoid process of scapula
I = Radial tuberosity of radius
Brachialis:
O = Distal anterior surface of humerus
I = ulnar tuberosity and coronoid process of ulna
Brachioradialis:
O = Lateral (supracondylar ridge) of distal end of humerus
I = Styloid process of radius

b) Adductor longus inserts on linea aspera of femur
c) Vastus lateralis originates on linea aspera of femur
d) Biceps femoris inserts on linea aspera of femur
d) Biceps femoris
O = Long head: Ischial tuberosity of ischium. Short head: Linea aspera of femur
I = Head of fibula
TRUE OR FALSE

b. Trapezius; Illiocostalis;Capitis splenius;Interspinales
c. Interspinales;Capitis splenius; Illiocostalis; Trapezius
d. Trapezius; Capitis splenius; Illiocostalis; Interspinales

Besides Teres Major, what other two muscles insert on the intertubercular sulcus?
Latissimus dorsi
Pectoralis major
What is the difference between the Palmar interossei and the Dorsal interossei?
-Palmar interossei- in between the metacarpals. does adduction of the fingers.
-Dorsal interossei- abduction of the fingers also does flexion at the metacarpal-phalangeal joints, and do extension at the interphalangeal joints
The femoral triangle is formed by the inguinal ligament, lateral border of adductor longus muscle and border of sartorius muscle
The femoral triangle contains the femoral nerve, femoral artery, femoral vein

Infraspinatus
Pectoralis major
Teres minor
Supraspinatus

c) Iliopsoas inserts on the lesser trochanter
d) Gracillis adducts the thigh, but also flexes the leg
b) Sartorius orignates on the Iliac spine
