Back 21

Plexus

Front 22

Description of the Cervical Plexus

Back 22

Associated with the neck, shoulder, and diaphragm

Phrenic nerve emerges from it

Front 23

Description of the Bracial Plexus

Back 23

Associated with the upper extremities Major nerves are Axillary, Radial, Median, Musculocutaneous, Ulnar

Associated with the upper extremities Major nerves are Axillary, Radial, Median, Musculocutaneous, Ulnar

Front 24

Description of the Lumbrosacral

Back 24

Associated with the lower torso and lower extremities

Major nerves are Femoral, Obturator, and Sciatic

Front 25

This nerve works with the diaphragm and, if damaged, leads to impaired breathing

Back 25

Phrenic

Front 26

This nerve works with the shoulder muscles and, if damaged, leads to crutch palsy

Back 26

Axillary

Front 27

This nerves works with the arm, forearm, hand, thumbs, and first two fingers. If impaired, damage could result in Wristdrop and radial nerve palsy

Back 27

Radial

Front 28

This nerve works with the forearm and the muscles of the hand and, if damaged, can lead to an inability to pick up small objects

Back 28

Median

Front 29

This nerve works with the wrist and muscles of the hand and, if damaged, can result in Clawhand

Back 29

Ulnar

Front 30

This nerve works with the ribcage and damage leads to impaired breathing

Back 30

Intercostal

Front 31

This nerve works with the abdomen, thigh, leg, and foot. Damage to this nerve leads to an inability to extend leg and flex hip

Back 31

Femoral

Front 32

This nerve works in your lower trunk, thigh and leg. Damage to it can lead to an inability to extend hip and flex knee

Back 32

Sciatic

Front 33

This nerve works with the lateral area of leg and foot. Damage to it leads to footdrop.

Back 33

Common Peroneal

Front 34

This nerve works with the Posterior area of the leg and foot. Damage to this nerve can result in a shuffling gait.
