Explanation / Answer

1.Median Nerve which is the main nerve of the front of the forearm which supplies the pronator teres in the forearm,thenar muscles of the hand when get injured at the forearm level, results inthe inability of pronation of the forearm and paralysis of the first and second lumbricals makes the index and middle fingers lag behind in slowly making a fist.

2.Radial Nerve which provide motor innervation to the triceps brachii,anconeus muscle and the extrinsic extensors of the wrist and hands when gets injred, there is a medical condition in which the wrist and the fingers cannot extend at the metacarpophalangeal joints. the wrist remains partially flexed due to an opposing action of flexors muscles of the forearm.

3.Sciatic nerve injury due to improper placement of intramuscular injections in the gluteal regeion describes a situation where there is a loss of movement and or lack of sensation at the affected lower extremity with or without pain.

4.Ulnar nerve when gets injured at or near the medial epicondyle, results in the tingling sensation in the ring and small fingers,pain in the forearm and weakness in the hand.

5.The injury will be at below C8-T1 level in the spinal cord along with the Ulnar nerve irritation.

6.Obturator Nerve which is responsible for motor innervation of the adductor muscles of the lower limb(adductor longus,adductor brevis,adductor magnus etc) when gets injured, there may be problem in adducting the lower limbs.

7.common peroneal nerve injury at the fibular site as this nerve becomes superficial near the head of fibula,could cause difficulty in dorsiflexion of foot.

8.Sciatic Nerve.
