Get Empowered: The Ultimate Labeled Guide to Your Arm Muscles Revealed! - Abbey Badges

Understanding the Context

Why Knowing Your Arm Muscles Matters

Your arms are powerful, dynamic tools involved in countless movements—from lifting, pushing, pulling, to precise actions requiring fine motor control. Mastering the names, functions, and weaknesses of your biceps, triceps, forearms, and associated muscles empowers you to train smarter, avoid injury, and build balanced strength and definition.

The Ultimate Labeled Guide to Your Arm Muscles

Key Insights

This guide clearly labels every major muscle in your arms, complete with ihrer roles, primary actions, and how they interact to create movement.

Upper Arm Muscles

1. Biceps Brachii
   

   • Location: Front of the upper arm
     
   • Key Function: Flexion of the elbow; assists in supinating the forearm (rotating your palm up)
     
   • When Engaged: Bending your arm, lifting objects, or performing curls

2. Triceps Brachii
   

   • Location: Back of the upper arm
     
   • Key Functions: Extension of the elbow; crucial for pushing movements
     
   • Subdivisions:
     
     • Long Head
       
     • Lateral Head
       
     • Medial Head (Triceps Algebra)
       
   • When Engaged: Pushing exercises, straightening your arm

Forearm Muscles

Final Thoughts

3. Wrist Flexors (e.g., Flexor Carpi Radialis, Flexor Carpi Ulnaris)
   

   • Location: Inner and outer forearm
     
   • Key Functions: Flexing the wrist (bending the hand toward the forearm)
     
   • Etymology Label: Radial and Ulnar flexor tendons work in harmony for grip and fine movement

4. Wrist Extensors (e.g., Extensor Carpi Radialis Longus, Extensor Carpi Ulnaris)
   

   • Location: Outer forearm
     
   • Key Functions: Extending the wrist
     
   • Etymology Label: Active when you push open a door or extend your hand in balance
