Study Notes
- Trapezius muscles are located on each side of the upper back.
- These muscles facilitate movement of the head, neck, and upper back.
- They also contribute to maintaining and adjusting posture.
- Overuse, injuries, and nerve damage are common causes of trapezius muscle pain.
Overview
- Each trapezius muscle has three sections.
- They extend from the base of the neck to the mid-back.
- The trapezius, often called "traps", is a large back muscle.
- Trapezius muscles are skeletal muscles and part of the musculoskeletal system.
- These muscles are used frequently.
- Injury is less common than in other muscles.
- Consult a healthcare provider for persistent back, neck, or head pain lasting over a week.
Function
- Trapezius muscles support the body and facilitate movement.
- They facilitate head tilting, head turning, posture adjustment, torso twisting, shoulder shrugging, and scapula movement for arm lifting.
- These muscles are used almost constantly.
- Traps help change posture while wiggling in a seat.
Anatomy
- Trapezius muscles are located on either side of the upper back, extending from the base of the neck across the shoulders to the mid-back.
- The name "trapezius" comes from their trapezoid shape.
- Each trapezius muscle comprises three sections: upper (superior), middle, and lower (inferior).
- Traps connect to the skull, spine, ribs, and shoulder bones.
- The upper section connects to the skull and cervical spine.
- The middle and lower sections connect to bones in the thoracic spine.
- They also connect to the scapula and clavicle.
- Cranial nerve XI (spinal accessory nerve) controls trapezius muscle movement.
- The C3 and C4 cervical nerves provide sensation.
Conditions and Disorders
- Trapezius muscle pain can manifest as upper back pain, neck pain, headaches, muscle spasms or cramps, and pain between the shoulder blades.
- Additional symptoms include limited mobility, neck and shoulder stiffness, swelling, bruising, and tenderness.
- Common issues causing trap muscle pain include stress, muscle strains, posture issues, and nerve damage.
- Stress can cause unconscious muscle tension, especially in the shoulders, upper back, and neck.
- Muscle strains, though less common in traps, can result from sports injuries or repetitive strain.
- Slouching can strain the traps and other upper back muscles.
- Nerve damage can cause radiating pain in the traps, neck, shoulders, and head.
Care
- Focus on overall health to maintain strong muscles.
- To avoid trapezius problems:
- Exercise, stretch, and stay flexible to improve range of motion, strengthen, and relax muscles.
- Maintain a healthy weight to reduce the risk of muscle strain.
- Warm up before exercising to prevent injury.
