The "funny bone" got its nickname because of that funny feeling you get after you hit it. But your funny bone isn't actually a bone at all. Running down the inside part of your elbow is a nerve called the ulnar nerve. The ulnar nerve lets your brain know about feelings in your fourth and fifth fingers.

Origin and insertion The extensor carpi ulnaris muscle originates from the lateral epicondyle of humerus, via the common extensor tendon, and adjacent fascia. ... Shortly after entering the hand, the tendon passes over the dorsal surface of triquetral bone and inserts to the medial aspect of the base of metacarpal bone 5.

The flexor carpus radialis, flexor carpus ulnaris, and palmaris longus muscles all have their origins on the humerus of the upper arm and insert into the carpals and metacarpals on the palmar side of the hand. Working together these muscles flex the hand at the wrist.

In severe cases, ulnar nerve entrapment can cause weakness in the hand and loss of muscle mass. What You Need to Know. The condition occurs when the ulnar nerve becomes compressed as it passes through the wrist or elbow. Ulnar nerve entrapment is also known as: Bicycler's neuropathy or handlebar palsy.

In music, a barre chord (also spelled bar chord or, rarely, barr chord) is a type of chord on a guitar or other stringed instrument, that the musician plays by using one or more fingers to press down multiple strings across a single fret of the fingerboard (like a bar pressing down the strings).

Pinched median nerve A pinched nerve occurs when too much pressure is applied to a nerve by surrounding tissues, such as bones, cartilage, muscles or tendons. This pressure disrupts the nerve's function, causing pain, tingling, numbness or weakness. A pinched nerve can occur at a number of sites in your body.

Neuropathies frequently start in your hands and feet, but other parts of your body can be affected too. Neuropathy, often called peripheral neuropathy, indicates a problem within the peripheral nervous system. Your peripheral nervous system is the network of nerves outside your brain and spinal cord.

Guyon canal syndrome is a relatively rare peripheral ulnar neuropathy that involves injury to the distal portion of the ulnar nerve as it travels through a narrow anatomic corridor at the wrist. The ulnar nerve originates from C8-T1 and is a terminal branch of the brachial plexus.

The ulnar artery, along with the radial artery, is responsible for the arterial supply to the forearm and hand. The ulnar artery arises in the cubital fossa and traverses through the medial (ulnar) side of the forearm and ends within the medial portion of the hand as the superficial palmar arch.

Overuse peripheral nerve injuries can cause pinched nerves that lead to numbness and pain in your arm or forearm. For example: carpal tunnel syndrome, which affects the median nerve between ligaments and the bones in your forearm. cubital tunnel syndrome, which affects the ulnar nerve near your elbow.

Doing any repetitive motion with your hands, whether it's typing, sewing, driving, or writing, can cause carpal tunnel syndrome. The condition gets its name from an area in your wrist called the carpal tunnel. Running through this tunnel is the median nerve, which sends feeling to your palm and most of your fingers.

The radius and the ulna are long, slightly curved bones that lie parallel from the elbow, where they articulate with the humerus, to the wrist, where they articulate with the carpals. The radius is located laterally, near the thumb, and the ulna medially, near the little finger.

Despite having many adjacent structures, the radius and ulna are directly connected via a syndesmosis called the radioulnar fibrous joint. It is an interosseous membrane that runs between the medial aspects of the bones and sections off the region of the forearm into anterior and posterior compartments.

Bones and joints. Pronation and supination are movements that occur at the proximal radioulnar joint. The head of the radius is discoid and fits with the radial neck within the circular annular ligament, that attaches the proximal radius to the ulna.

Nerve tissues usually heal much more slowly than other types of tissues. However, some ulnar nerve palsy symptoms may get better without treatment. There are a number of possible treatments for ulnar nerve palsy, including: over-the-counter pain relievers.
