The part of the arm between the elbow and the wrist is called the forearm.
The forearm is a critical section of the upper limb, serving as the bridge between the elbow joint and the wrist. It plays a vital role in various movements, including pronation (turning the palm downward) and supination (turning the palm upward).
Anatomy of the Forearm
The forearm contains two long bones:
- Radius: Located on the thumb side of the forearm.
- Ulna: Located on the little finger side of the forearm.
These bones articulate with each other at the proximal and distal radioulnar joints, which allow for the pronation and supination movements. Many muscles, nerves, and blood vessels are housed in the forearm.
Functionality
The muscles of the forearm control wrist and hand movements, including:
- Flexion and extension
- Abduction and adduction
- Pronation and supination
These movements are essential for gripping, manipulating objects, and performing fine motor tasks.
Potential Injuries
The forearm is susceptible to various injuries, including:
- Fractures: Breaks in the radius or ulna bones.
- Sprains: Ligament injuries around the wrist or elbow.
- Strains: Muscle or tendon injuries.
- Carpal Tunnel Syndrome: Compression of the median nerve at the wrist.
Prompt medical attention is crucial for proper diagnosis and treatment of forearm injuries.
In summary, the forearm is the anatomical region located between the elbow and the wrist, consisting of the radius and ulna bones and playing a vital role in hand and wrist movement.
