Wrist vs. Forearm — What's the Difference?
Edited by Tayyaba Rehman — By Maham Liaqat — Updated on May 6, 2024
The wrist is a complex joint connecting the hand to the forearm, enabling diverse movements, whereas the forearm is the elongated section between the elbow and wrist, consisting of the radius and ulna bones.

Key Differences
The wrist comprises multiple small bones, ligaments, and tendons that facilitate movement of the hand in various directions, such as flexion, extension, and rotation. In contrast, the forearm acts primarily as a stabilizing structure and a lever to facilitate these movements.
Structurally, the wrist's complexity allows for fine motor skills and delicate manipulations, like typing or drawing. Meanwhile, the forearm's muscles and bones provide the necessary force and support for such tasks.
The wrist's flexibility makes it susceptible to injuries like sprains or fractures. On the other hand, the forearm's injuries often involve muscle strains or bone fractures due to impacts or overuse.
In terms of muscle attachment, the forearm houses several important muscles that control movements at the wrist and elbow. The wrist itself does not contain muscles but is surrounded and controlled by tendons extending from the forearm muscles.

Wrist
In human anatomy, the wrist is variously defined as (1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus and; (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones, thus referred to as wrist joints. This region also includes the carpal tunnel, the anatomical snuff box, bracelet lines, the flexor retinaculum, and the extensor retinaculum.
Forearm
The forearm is the region of the upper limb between the elbow and the wrist. The term forearm is used in anatomy to distinguish it from the arm, a word which is most often used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower "arm" is called the forearm.

Common Curiosities
What makes up the forearm?
The forearm consists of the radius and ulna bones, along with various muscles and nerves.
How do wrist injuries commonly occur?
Wrist injuries commonly occur due to falls, sudden impacts, or repetitive stress.
Can you strengthen your wrist?
Yes, you can strengthen your wrist by exercises that enhance the tendons and muscles coming from the forearm.
What is the primary function of the wrist?
The primary function of the wrist is to provide mobility and dexterity to the hand.
What role does the forearm play in arm movements?
The forearm plays a critical role in arm movements by serving as a lever and supporting muscle contractions.
How do you protect your wrist from injury?
Protecting the wrist involves strengthening forearm muscles, using protective gear, and practicing proper technique in physical activities.
What is unique about the wrist’s structure?
The wrist's structure is unique due to its complex arrangement of multiple small bones and joints allowing versatile movements.
