Explanation / Answer

1.Right ulnar nerve

EXPLANATION:

Ulnar nerve is a branch of the medial cord of the brachial plexus. The ulnar nerve provides sensation to half of the 4th and the entire 5th finger. It innervates muscles in the forearm and hand that allow the wrist and finger to flex (flexion) and fine finger control.

2.Right brachial plexus nerve

EXPLANATION

Brachial plexus nerve is actually a network of nerves that consists of the last 4 cervical nerve roots (vertebrae C5-C8) and the first thoracic (vertebrae T1) nerve root, and ensures motion and feeling in the upper limbs.Midshaft Fracture in right humerus indicates injury to right brachial plexus nerbe

3.Sciatic nerve

EXPLANATION

The sciatic nerve is the largest single nerve in the body, extending from the back of the pelvis down the back of the thigh. It is the primary nerve of the leg and is responsible for innervating the muscles in the hip and lower limbs (including the tibial nerve and common fibular nerve).

4.Femoral nerve

EXPLANATION

Femoral nerve is a part of the lumbar plexus. The femoral nerve provides sensation to the anterior (front) aspect of the thigh. It innervates muscles in the anterior thigh which allow the knee to extend.

5.Left median nerve

EXPLANATION

Median nerve is a branch of the medial and lateral cords of the brachial plexus. The median nerve provides sensation to the thumb, 1st, 2nd, 3rd and half of the 4th finger. It innervates muscles in the forearm and hand that allow pincher grasp (the ability to grasp an object between the thumb and forefinger).

6.Common peroneal nerve

EXPLANATION

This nerve is a branch of the sciatic nerve and is made up of the deep and superficial peroneal branches. They provide sensation to the anterior (front) and lateral (side) parts of the legs and top of the feet. They innervate muscles in the legs that pull the ankle and toes up (dorsi flexion).

7.Right tibial nerve.

Explanation:

Tibial nerve is a branch of the sciatic nerve and provides sensation to the bottom of the foot. It innervates the calf muscles which allow the foot and toes to flex (plantar flexion).

8.Tibial nerve

Explanation

Tibial nerve is a branch of the sciatic nerve and provides sensation to the bottom of the foot. It innervates the calf muscles which allow the foot and toes to flex (plantar flexion).fracture of the superior tibia injures the tibial nerve.

9.Common peroneal nerve

Explanation:

The common peroneal nerve is the most commonly injured nerve in the leg due to its superficial location where it courses laterally around the neck of the fibula. This location makes the common peroneal nerve susceptible to injury when a straumatic insult results in fracture of the neck of the fibula.

10.Right radial nerve

Explanation:

Radial nerve branches from the posterior (back) cord of the brachial plexus. The radial nerve provides sensation to a portion of the skin on the back of the hand. It innervates muscles in the arm that extend the elbow and muscles in the forearm, which enables the wrist and fingers to straighten or extend.
