Anatomy of the Arm & Hand — Part 6 | Elbow Muscle Function

Описание: In this lesson, we explore the major muscles that act on the elbow joint, focusing on the biceps brachii and triceps brachii. Understanding their insertions, actions, and interactions is essential for safe movement, strength, and injury prevention in yoga practice.

🧠 Anatomy of the Arm & Hand — Part 6 | Elbow Muscle Function

💪 Biceps Brachii
• The biceps brachii has two heads: long head and short head
• Flexes the elbow, assists in shoulder flexion, and supinates the forearm
• Crosses three joints: shoulder, elbow, and radial (forearm)
• Full contraction occurs when elbow flexion and forearm supination happen together

📍 Key Insertions
• Long head: glenohumeral joint capsule and bicipital groove
• Short head: coracoid process of the scapula
• Distal insertion: radius

🦴 Supporting Elbow Flexors
• Brachialis – primary elbow flexor
• Brachioradialis – flexes elbow, inserts on radius near thumb
• These assist the biceps for smooth and stable flexion

💪 Triceps Brachii
• Antagonist to the biceps, primary elbow extensor
• Three heads: long, lateral, medial
• Long head also assists in shoulder extension
• All three heads insert on the olecranon of the ulna

📝 Student Activity
• Google Classroom exercise: palpate and mobilize the biceps and triceps
• Explore insertions and actions, then upload reflections and observations

🎥 Video Study
• Selected segment: 3:59–4:28 (focus on biceps and triceps insertions and function)
• Full video available for deeper exploration

🧘‍♀️ Why This Matters in Yoga
• Proper elbow mechanics enhance arm balances, planks, and chaturanga
• Awareness prevents strain and injuries during repetitive or loaded poses
• Understanding antagonist–agonist relationships supports safer, stronger movement

🎓 For 200-Hour Yoga Teacher Training Students
