The cubital nerve is also known as the ulnar nerve and is responsible for the sensations in the pinky finger and half of the ring finger. It runs from the neck down to the hand and can be easily compressed in the elbow causing a condition known as cubital tunnel syndrome. Other synonyms for the cubital nerve include the ulnar sensory nerve, ulnar collateral nerve, cubital collateral nerve, and posterior ulnar recurrent nerve. Any damage or injury to these synonymous nerves can result in numbness, tingling, and weakness in the affected areas of the hand and forearm. It is important to seek medical attention if you experience any of these symptoms.
