Understanding Hand and Wrist Anatomy
Introduction to Hand and Wrist Anatomy
The human hand is a marvel of engineering, intricately designed to perform a wide range of tasks, from the delicate art of writing to the strength needed to carry heavy objects. Comprising the wrist, palm, and fingers, the hand is a complex structure made up of 27 bones, 27 joints, 34 muscles, over 100 ligaments and tendons, and numerous blood vessels and nerves. This intricate network enables us to carry out our daily activities with precision and dexterity.
Understanding the anatomy of the hand is crucial, especially when considering the impact of conditions or injuries that can affect this vital part of the body. If you're experiencing discomfort or pain, it's essential to grasp the basics of hand anatomy, as it can help you better understand the underlying causes and treatment options. At Team Rehab uk in Northampton (Brixworth) and Corby, we offer comprehensive care to help you regain full hand function and alleviate pain.
Anatomy of the Wrist and Hand
The foundation of the hand's structure lies in its bones, which provide the necessary support and shape. The wrist itself is made up of eight small bones known as carpal bones. These bones are connected to the two long bones of the forearm—the radius and the ulna—to form the wrist joint. The wrist joint plays a crucial role in the hand's ability to move and bear weight.
From the wrist, the hand extends into five metacarpal bones that form the palm. Each of these metacarpal bones connects to a finger at a joint known as the metacarpophalangeal (MCP) joint, commonly referred to as the knuckle joint. This joint allows the fingers to flex and extend, essential movements for gripping and holding objects.
The fingers themselves are composed of bones called phalanges. Each finger contains three phalanges, separated by two joints known as interphalangeal joints.
The thumb, however, is unique in that it has only two phalanges and one interphalangeal joint. The first joint, located closest to the knuckle, is called the proximal interphalangeal (PIP) joint, while the joint near the fingertip is the distal interphalangeal (DIP) joint. These joints work together like hinges, enabling the fingers to bend and straighten with ease.

Soft Tissues of the Hand
The bones of the hand are supported and held together by various soft tissues, including ligaments, tendons, and muscles. These soft tissues not only provide stability but also enable movement and dexterity, essential for performing tasks ranging from typing on a keyboard to playing a musical instrument.
Articular Cartilage: This smooth material covers the ends of bones at each joint, acting as a shock absorber and allowing for smooth, pain-free movement. Articular cartilage is vital for the seamless functioning of the hand's many joints.
Ligaments: Ligaments are tough, rope-like tissues that connect bones to other bones, providing stability to the joints. Each finger joint is supported by two collateral ligaments on either side, preventing the joints from bending sideways. The strongest ligament in the hand, the volar plate, connects the proximal and middle phalanx on the palm side, preventing the PIP joint from bending backward (hyperextension). Proper ligament function is crucial for maintaining the alignment and integrity of the hand's joints, and any injury to these ligaments can significantly impact hand function.
The sheer number of ligaments is quite amazing and unless you ae going to try surgery on yourself, listing al of these individually is really not necessary, however they are shown below for your reference.
Muscles and Tendons of the Hand
Muscles: Muscles are fibrous tissues responsible for producing movement by contracting. There are two types of muscles in the hand: intrinsic and extrinsic muscles.
-
Intrinsic Muscles: These small muscles originate within the wrist and hand and are responsible for the fine motor movements of the fingers, such as those required for writing or playing the piano. Intrinsic muscles allow for precise and delicate movements, which are essential for tasks that require manual dexterity.
-
Extrinsic Muscles: These larger muscles originate in the forearm or elbow and control the movement of the wrist and hand. They are responsible for the gross motor movements of the hand, such as gripping and lifting. The extrinsic muscles position the wrist and hand while the fingers perform fine motor tasks. Each finger has six muscles that control its movement: three extrinsic and three intrinsic muscles. Additionally, the index and little fingers each have an extra extrinsic extensor muscle, giving them greater independence and range of motion.
Tendons: Tendons are the connective tissues that link muscles to bones. When muscles contract, they pull on the tendons, which in turn pull on the bones, causing movement. In the hand, the tendons are responsible for both bending and straightening the fingers.
-
Flexor Tendons: Located on the palm side of the hand, these tendons enable the fingers to bend.
-
Extensor Tendons: Positioned on the back of the hand, these tendons help the fingers straighten.
The coordination of these tendons is vital for the smooth and efficient functioning of the hand.
Nerves of the Wrist and Hand
The hand's movements and sensations are controlled by a complex network of nerves that carry signals between the brain and the muscles. These nerves also transmit sensory information, such as touch, pain, and temperature, back to the brain.
The three primary nerves that supply the hand are:
Ulnar Nerve: This nerve crosses the wrist through an area known as Guyon’s canal and provides sensation to the little finger and half of the ring finger. The ulnar nerve is also responsible for controlling many of the hand's fine motor movements.
Median Nerve: The median nerve travels through the carpal tunnel at the wrist and supplies sensation to the palm, thumb, index finger, middle finger, and part of the ring finger. This nerve plays a crucial role in hand function, and compression of the median nerve can lead to conditions like carpal tunnel syndrome.
Radial Nerve: Running along the thumb side of the forearm, the radial nerve provides sensation to the back of the hand, particularly from the thumb to the middle finger. The radial nerve also contributes to the extension of the wrist and fingers.
Any disruption to these nerves, whether due to injury or compression, can result in significant impairment of hand function, including loss of sensation, weakness, or even paralysis.
Ensuring Optimal Treatment Outcomes
At Team Rehab UK, we emphasise that treatments which are not effective should not continue beyond accepted clinical timescales without further in-depth investigations. We prefer these additional assessments to be conducted by consultant specialists outside our company’s financial interests. This approach ensures we receive an unbiased second opinion, guaranteeing that the care you receive is the most clinically appropriate.
Blood Vessels of the Wrist and Hand
The hand is richly supplied with blood vessels that ensure it receives the necessary oxygen and nutrients to function properly. The two main arteries that supply blood to the hand are the ulnar and radial arteries.
Ulnar Artery: This artery runs alongside the ulnar nerve through Guyon’s canal, providing blood to the front of the hand, fingers, and thumb.
Radial Artery: The largest artery in the hand, the radial artery travels across the front of the wrist near the thumb. It is the artery where the pulse is commonly measured. The radial artery supplies blood to the back of the hand, as well as the thumb and fingers.
In addition to these major arteries, numerous smaller blood vessels branch out across the hand, ensuring that all areas receive adequate blood flow. Proper circulation is essential for the health and function of the hand, and any interruption can lead to serious complications, including tissue damage and loss of function.
Hand and Wrist Bursae
Bursae: Reducing Friction for Smooth Movement
Bursae are small, fluid-filled sacs located throughout the body, including the hand. These sacs act as cushions, reducing friction between tendons, bones, and skin as they move against each other. Bursae contain synovial cells that secrete a lubricating fluid, which further aids in the smooth movement of the hand’s components. While typically protective, bursae can sometimes become inflamed, leading to a painful condition known as bursitis.
The Importance of Hand Anatomy in Daily Life
The human hand's intricate design allows us to perform countless tasks that are essential to our daily lives, from simple activities like eating and dressing to more complex tasks like playing musical instruments or typing. However, any disruption to the hand's anatomy—whether due to injury, disease, or degenerative conditions—can significantly impact its function and our ability to perform these tasks.
