Multiple choice questions on anatomy 1 to 20 Questions and Answers

  1. D) The tibial nerve is a branch of the sciatic nerve. The tibial nerve innervates the gastrocnemius, popliteus, soleus, and plantaris muscles. The sural nerve is a cutaneous branch of the tibial, but also receives innervation from the peroneal nerve.
  2. C) Posterior herniations commonly miss the nerve in the foramen, and instead tends to affect the nerve one level distal. This is because the roots from the level below are located more laterally before exiting the canal, making them more vulnerable to impingement.
  3. C) The lateral meniscus is larger than the medial meniscus, which is shaped like a “C.” There are no structures named anterior or posterior meniscus.
  4. B) The distal humerus has two surfaces of articulation: the capitellum and the trochlea. The radial head articulates with the capitellum and the ulna articulates with the trochlea.
  5. C) Although there is considerable overlap between adjacent dermatomes, the C7 dermatome supplies sensation to the area of skin over the middle finger. The C6 dermatome supplies sensation to the first digit, whereas the C8 dermatome supplies the fifth digit. The C5 dermatome supplies sensation to the lateral aspect of arm.
  6. D) The brachioradialis muscle is innervated by the radial nerve.
  7. C) The dorsal scapular nerve innervates both levator scapulae and the rhomboids.
  8. B) The scaphoid bone is the only carpal bone that crosses both carpal rows. This position not only provides stability, but also places the scaphoid at the greatest risk of injury.
  9. D) The semispinalis muscle is one of the deep layers of intrinsic back muscles and arises from approximately half of the spine—hence its name. It is divided into three parts: semispinalis capitis, semispinalis thoracis, and semispinalis cervices. The other muscles in the deep layer of intrinsic back muscles are the multifi dus and the rotators. Collectively, the deep layer of the intrinsic back muscles is known as the transversospinal muscle group.
  10. C) The anterior longitudinal ligament runs anteriorly and vertically attaching to the front of each vertebra. It traverses all of the vertebral bodies and intervertebral disks and helps resist extension.
  11. A) The ACL originates in the lateral femoral condyle and attaches to the medial tibial eminence after traveling through the intercondylar notch.
  12. A) Tibialis anterior is an ankle dorsiflexor and inverter. Peroneus tertius dorsiflexes and everts the foot. Peroneus brevis everts and plantar flexes the foot. The plantaris is a weak plantar flexor.
  13. C) The “watershed zone” of the Achilles is in the substance of the tendoachilles, approximately 2 to 5 cm above the calcaneal insertion of the tendon. This is an area of hypovascularity where most ruptures occur.
  14. B) Overall, there is 2° of glenohumeral motion for every 1° of scapulothoracic motion during shoulder abduction (120° of glenohumeral motion to 60° of scapulothoracic motion). However, in a normal shoulder, the majority of the initial ROM occurs at the glenohumeral joint when the arm is supinated.
  15. A) Endoneurium is the connective tissue that surrounds each individual axon and its myelin sheath. The perinurium surrounds the fascicles. The epineurium is the connective tissue that surrounds a peripheral nerve. The myelin sheath itself improves conductance of the electrical signal down an axon and is not part of the surrounding supportive structure.
  16. C) The subscapular nerve innervates the subscapularis and the teres major muscles.
  17. D) The DIO muscles are part of the intrinsic group of muscles in the hand. The DIO proximally attach at adjacent metacarpals and distally attach to proximal phalanges. Their main function is to abduct the digits and for MCP flexion.
  18. A) The FDS inserts at the middle phalanx of the index, middle, ring, and small fingers. The FDS muscle’s origins are the medial humeral epicondyle, the coronoid process of the ulna, and the upper anterior surface of the radius. Its main action is to fl ex the fingers at the proximal interphalangeal (PIP) joints. However, it also acts to fl ex the hand and wrist.
  19. A) Hinged joints only allow a small range of motion (ROM) (eg, the humerus with the ulna and radius). Pivot joints allow a wide ROM, but not as much freedom as ball-and-socket joints (between atlas and axis). Gliding joints allow sliding motion between two bones (eg, wrist and ankle). Ball-and-socket joints have full ROM (hips, shoulders).
  20. C) Most meniscal tissue is avascular and depends on passive diffusion and mechanical pumping to provide nutrition to the fi brocytes within the meniscal substance. The limited peripheral blood supply originates from the medial and lateral inferior and superior geniculate arteries. Repair is usually only successful in well-vascularized areas.

Dr .Lalit Choudhary
Hii everyone, I'm Dr Lalit Choudhary PT. Born and brought up in delhi. Practicing as a professional PHYSIOTHERAPIST. As a therapist I love to interact with others and and get myself updated regarding all the social issues which are leading my countrymen to distress themselves. Yes, I agree that Iam a workaholic but my work gives me immense pleasure but there are sometimes when I feel stressed up so to relax myself I travel to new places, meet new people and try to adopt their culture. Most of the time I like to travel hills as it helps me to relax and enjoy our nature beauty. For being a good therapist and to deal with all the difficulties I always prefer to be good listener and have good patience that is what my strength is. I also work as a social worker and the Founder of thesocialphysiofitnessclub and PHYSIO FIT INDIA. In last I just want to say that " I believe that physical therapy is not just a therapy but actually a remedy which not only make you physically fit but also adds happiness, joy and more days to your life." So don't just sit and thought now it's time to stand and work on yourself.
