Ulnar nerve motor
Definition
Finger abduction or "fanning" is innervated by the T1 nerve root via the ulnar nerve.
Term
Ulnar sensory
Definition
5th finger
Term
Elbow injury causes what nerve damage?
Definition
ulna nerve
Term
Median nerve motor
Definition
Thumb opposition is innervated by the C8 and T1 nerve roots via the median nerve.

Finger flexion is innervated by the C8 nerve root via the median nerve.
Term
Median nerve sensory
Definition
Index finger
Term
Wrist disclocation
supracondylar fx
Definition
Median nerve
Term
Radial nerve motor
Definition
The triceps muscle is innervated by the C6 and C7 nerve roots via the radial nerve

The wrist extensors are innervated by C6 and C7 nerve roots via the radial nerve. The radial nerve is the "great extensor" of the arm: it innervates all the extensor muscles in the upper and lower arm.
Term
Motor musculocutaneous
Definition
The biceps muscle is innervated by the C5 and C6 nerve roots via the musculocutaneous nerve.
Term
Musculocutaneous sensory
Definition
Lateral forearm
Term
Axillary nerve (c5and 6) motor
Definition
Starting with the deltoids, ask the patient to raise both their arms in front of them simultaneously as strongly as then can while the examiner provides resistance to this movement. Compare the strength of each arm.

The deltoid muscle is innervated by the C5 nerve root via the axillary nerve.

Definition
Axillary nerve compression C 5-6 compromising deltoid muscle
Term
Pubic rami fractures sens and motor injury
Definition
femoral nerve

Knee extension by the quadriceps muscle is innervated by the L3 and L4 nerve roots via the femoral nerve
Term

Adduction of the hip is mediated by the L2, L3 and L4 nerve roots.
Term

Superficial peroneal
toe ankle eversion
sens lateral dorsum of foot
Term
Fibula neck fracture common cause of compartment syndrome and what nerve damage?
Definition
deep peroneal
ankle eversion
sens over 1st and 2d web space

Ankle dorsiflexion is innervated by the L4 and L5 nerve roots via the peroneal nerve.
Term
Posterior hip dislocation causes what nerve damage?
Definition
Sciatic nerve
sens foot
plantar flexion

Ankle plantar flexion is innervated by the S1 and S2 nerve roots via the tibial nerve.
Term
Acetabular fractures cause what nerve damage?
Definition
Hip abduction
HIP EXTENSION

Inf and sup gluteal muscle
Term
fibula neck fracture causes what nerve damage?
Definition
The superficial and deep peroneal nerves can be injured in patients with a fibular neck fracture. The superficial peroneal nerve controls ankle eversion and sensation over the lateral dorsum of the foot (S1 distribution). The deep peroneal nerve controls ankle and toe dorsiflexion and sensation over the dorsal 1st and 2nd web spaces. The posterior tibial nerve can become injured during knee dislocations and provides motor innervation for toe flexion and sensation to the sole of the foot.
Term
Plantar flexion
Definition
Tibial nerve (S1, S2).
Term
Dorsiflexion
Definition
Deep peroneal nerve (L4, L5, S1).
