1. Functions of the Spinal Nerves
-division of the peripheral nervous system
(PNS), which branch from the spinal cord
(CNS)
1. Intercostal - transmits motor impulses to Internal intercostal and
External intercostal muscles and muscles of the upper
abdominal wall; transmits sensory impulses from the
skin of the thorax and abdomen
2. Femoral - transmits motor impulses to the Iliacus, Psoas major,
Sartorius, Pectineus, Rectus femoris, Vastus lateralis,
Vastus medialis, and Vastus intermedius; transmits sensory
impulses from the skin of the thighs and legs
3. Ulnar - transmits motor impulses to Flexor carpi ulnaris; transmits
sensory impulses from the skin of the hands
4. Obturator - transmits motor impulses to Adductor magnus, Adductor
longus, Pectineus, and gracilis

2. 5. Sciatic - transmits motor impulses to Biceps femoris, Semitendinosus,
and Semimembranosus; transmit sensory impulses from the
skin of the thighs, legs, and feet
6. Radial - transmits motor impulses to Triceps brachii, brachioradialis,
Extensor carpi radialis longus, Extensor carpi radialis brevis,
Extensor digitorum, Extensor carpi ulnaris, and Supinator;
transmits sensory impulses from the skin of the forearms and
hands
7. Musculocutaneous - transmits motor impulses to Biceps brachii
Coracobrachialis, and Brachialis; transmits
sensory impulses from the skin of the forearms
8. Median - transmits motor impulses to Pronator teres, Flexor carpi
radialis, and Palmaris longus; transmits sensory impulses
from the skin of the hands

3. 9. Phrenic - transmits motor impulses to diaphragm
10. Axillary - transmits motor impulses to Deltoid and Teres minor;
transmits sensory impulses from the skin of the anterior,
lateral, and posterior regions of the arm
