Compared to the flexor group, how do the extensor group muscles tend to feel during palpation?

• A. Smaller and more sinewy
• B. Larger and more bulky
• C. Softer and more rounded
• D. Hard and fibrous

Answer: (A)

The main idea is that muscle bulk vs. tendon content influences how a muscle feels when you palpate it. The flexor muscles in the forearm are generally thicker and bulkier because they power strong grip and finger flexion, so they feel substantial to touch. The extensor muscles on the back of the forearm have longer tendons and less overall muscle mass in the same area, giving them a leaner, more sinewy feel when you palpate. So, the extensor group tends to be smaller in cross-section and has a fibrous, stringy texture rather than a bulky mass. That’s why smaller and more sinewy is the best description. The other options don’t match the typical anatomy and palpation experience.
