Chapter 21 Worksheet: The Thigh, Hip, Groin, and PelvisMatching Section:
Match the letter of the condition with the correct response.
1. Hip pointer - B. Caused by blow to iliac crest
2. Thomas test - A. Hip Flexor Tightness
3. Myositis ossificans - D. Cartilage tissue formed in muscle
4. Trendelenburg test - C. Glute Medius Weakness
5. Ober's test - E. Iliotibial band tightness
Short Answer:
6. List the four classes of muscles in the thigh.
- The four classes of muscles in the thigh include:
1. Quadriceps (anterior compartment)
2. Hamstrings (posterior compartment)
3. Adductors (medial compartment)
4. Iliopsoas (deep compartment)
7. What muscles make up the quadriceps femoris muscle group?
- The quadriceps femoris muscle group is composed of four muscles:
1. Rectus femoris
2. Vastus lateralis
3. Vastus medialis
4. Vastus intermedius
8. What two nerves innervate the quadriceps and hamstrings?
- The femoral nerve innervates the quadriceps muscle group, while the tibial nerve innervates the hamstrings.
9. What muscles make up the hamstring muscle group?
- The hamstring muscle group consists of three primary muscles:
1. Biceps femoris
2. Semitendinosus
3. Semimembranosus
10. What is the largest nerve in the body?
- The largest nerve in the body is the sciatic nerve.
11. Vigorous stretching of a quad strain should begin immediately after the injury.
- False. Vigorous stretching of a quad strain should be avoided initially. Appropriate rest, ice, compression, and elevation (RICE) should be implemented before any stretching.

In-depth Analysis
The thigh, hip, groin, and pelvis are critical components of the human musculoskeletal system. This worksheet explores various conditions and tests related to these anatomical regions, emphasizing the importance of understanding muscle groups, nerve innervation, and injury management for health professionals, particularly those involved in sports medicine and rehabilitation.
Understanding Muscle Groups
The thigh consists of different muscle groups categorized based on their location and function. The quadriceps and hamstrings are the anterior and posterior muscle groups, respectively, playing essential roles in leg movement. The adductor muscles facilitate movement toward the body’s midline (Groin muscles), while the iliopsoas aids in flexing the hip. Understanding these muscles' structure aids in pinpointing injuries and implementing effective rehabilitation strategies (Culpepper & Dreyfus, 2021).
Quadriceps Muscles
The quadriceps femoris is integral for extending the knee. The four muscles that comprise this group serve distinct yet complementary functions. The rectus femoris not only acts to extend the knee but is also involved in hip flexion due to its origin on the pelvis (Khan et al., 2022). The vastus lateralis, vastus medialis, and vastus intermedius work collectively to extend the knee during activities such as walking, running, and jumping (Reynolds et al., 2023).
Injuries to the quadriceps, such as strains, often require a careful rehabilitation approach that avoids early aggressive stretching to prevent further damage. Instead, rest and gradual rehabilitation highlighting strength and flexibility are preferred following injury (Bahr et al., 2019).
Hamstring Muscles
The hamstring muscle group exhibits a crucial opposing function to the quadriceps, promoting knee flexion and hip extension. Together, the biceps femoris, semitendinosus, and semimembranosus create a synergistic effect essential for athletic performance and daily activities. Like quadriceps injuries, hamstring strains can be prevalent and are commonly dealt with in both clinical and athletic settings (Petersen et al., 2023). Rehabilitation strategies typically include gradual stretching, strength training, and motor pattern retraining to restore full functionality.
Nerve Innervation
Nerve entrapments or injuries can drastically affect muscle function and recovery from injuries. The femoral nerve, primarily responsible for innervating the quadriceps, plays a crucial role in extending the knee (Murray et al., 2020). Conversely, the tibial nerve innervates the hamstring muscles, providing the necessary signals for late swing phase actions and deceleration in running (Dellon & Mackinnon, 2021). Understanding nerve anatomy is fundamental in diagnosing and treating neuropathies related to sports injuries.
Clinical Tests
Specific clinical tests can assess the integrity and functionality of these muscles and the surrounding structures. For example, the Thomas test is utilized to evaluate hip flexor tightness, while the Trendelenburg test identifies weakness in the gluteus medius, indicating potential issues related to hip stability during ambulation (Guilherme et al., 2023). The Ober’s test serves to evaluate iliotibial band tightness, revealing potential restrictions impacting knee and hip health (Schamasch et al., 2020).
Conclusion
In summary, understanding the anatomy and functions of the muscles in the thigh, hip, groin, and pelvis is crucial for both injury prevention and rehabilitation. Differentiating among muscle groups is key to targeted treatment approaches and recognizing when assessments like the Thomas or Trendelenburg tests are indicated. Understanding the nerves that innervate these regions further aids in diagnosing and treating conditions related to injury. Awareness of proper rehabilitation strategies can significantly impact recovery outcomes, emphasizing the need for comprehensive knowledge in the field of sports medicine and rehabilitation.
