If you pinch your index finger in a door, pain sensations are carried via the _________blank nerve.Multiple Choiceradialmedianaxillarymusculocutaneousulnar

To determine which nerve carries pain sensations from the index finger when pinched in a door, we need to consider the anatomy of the hand and the functions of the listed nerves.

1. Radial Nerve: This nerve primarily innervates the posterior aspect of the arm and forearm, and while it does provide sensation to a part of the hand, it does not specifically cover the index finger.

2. Median Nerve: The median nerve is responsible for sensory innervation of the lateral aspect of the hand, including the pads of the index finger and thumb. It also plays a crucial role in fine motor control of the fingers.

3. Axillary Nerve: This nerve primarily innervates the deltoid and teres minor muscles and provides sensation to the skin overlying the shoulder, but it does not have a role in the index finger.

4. Musculocutaneous Nerve: This nerve primarily innervates the muscles of the anterior compartment of the arm and does not provide sensory innervation to the hand.

5. Ulnar Nerve: The ulnar nerve mainly supplies the medial aspect of the hand and is vital for the sensation of the little finger and half of the ring finger but not the index finger.

Final Answer

The correct answer is median nerve since it is responsible for carrying pain sensations from the index finger when pinched.
