1 The Wrist, Hand, & Fingers Skills Lab #4: Palpations

2 Instructions 1.Palpate the anatomical structures on your partner 2.Label the structures using various colored pens 1.Use a different color for each aspect, or a different color for bones, muscles, ligaments, etc. 2.Mark each with #s for easier identification

3 Anterior Palpations (Palmar) Skeletal 1.Radial styloid process 2.Ulnar styloid process 3.Pisiform 4.Hamate (hook) 5.Lunate 6.Scaphoid 7.1 st MCP joint

15 REVIEW QUESTIONS (2pts each) 1.Describe how to best palpate the muscles that flex the wrist. 2.Describe how to differentiate between the wrist extensors and the extensor digitorum muscle. 3.What is the term for the area between the APL/EPB and EPL muscles? What bone is located within that area?
