• Question 161:

  On which bone would you locate the infraglenoid tubercle?

  A. Clavicle

  B. Pelvic

  C. Calcaneuos

  D. Scapula

  Correct Answer: D

  Explanation: The infraglenoid tubercle is the attachment site of the long head of the triceps brachii and is located at the most superior aspect of the lateral border of the scapula.

• Question 162:

  Molecules of carbon dioxide and oxygen are passively exchanged by the process of ______________________.

  A. fission

  B. diffusion

  C. dispersion

  D. metabolism

  Correct Answer: B

  Explanation: Diffusion is the process where an area of higher concentration naturally flows into an area of lower concentration. Upon inspiration of air into the lungs, the alveolar sac is full of oxygen and the surrounding tissue is saturated with carbon dioxide rich blood. Next, the process of diffusion allows oxygen to flow into the blood from the alveolar sacs and carbon dioxide to flow from the blood into the alveolar sacs where it will be released through exhalation.

• Question 163:

  How many types of Schwann cells exist in the human body?

  A. 1

  B. 2

  C. 3

  D. 4

  Correct Answer: B

  Explanation: There are two types: myelinating and nonmyelating. Myelinating Schwann cells wrap around axons of motor and sensory neurons to form the myelin sheath, which acts to protect and support nerve functioning. Non-myelinating Schwann cells are involved with maintaining the health and vitality of the axon or nerve fiber.

• Question 164:

  _______________ is a proprioceptive sensory receptor located at the insertion of skeletal muscle which protects against damage from an excessive load or stretch.

  A. Golgi apparatus

  B. Golgi tendon organ

  C. Action potentials

  D. Spinal reflex

  Correct Answer: B

  Explanation: A Golgi tendon organ or GTO provides the sensory component to the Golgi tendon reflex, a phenomenon that protects a muscle/tendon from an excessive load or stretch.

• Question 165:

  Using the AC joint during an assessment would give an indication of ____________ symmetry.

  A. ankle

  B. hip

  C. shoulder

  D. head

  Correct Answer: C

  Explanation: The AC joint is the acromioclavicular joint located at the junction of the acromion process and the clavicle. The AC joint is assessed to indicate the symmetry of the shoulder.

• Question 166:

  A client has been diagnosed with pes cavus, which means they have _______________.

  A. flat feet

  B. high arches of the feet

  C. aninfected abscess

  D. extreme cavities

  Correct Answer: B

  Explanation: A client with pes cavus has a foot deformity characterized by an abnormally high medially longitudinal arch, also known as a high medial arch of the foot.

• Question 167:

  The tibial nerve is a distal branch of which nerve?

  A. Sciatic

  B. Brachial plexus

  C. Sacral plexus

  D. Lumbar plexus

  Correct Answer: A

  Explanation: The tibial nerve is a distal branch of the sciatic nerve which passes through the popliteal fossa where it divides into the medial and lateral plantar nerves.

• Question 168:

  Which of the following massage techniques would be best suited for a healed fracture?

  A. Trigger point

  B. Petrissage

  C. Tapotement

  D. Deep tissue

  Correct Answer: B

  Explanation: The action of petrissage is best suited for moving stagnant blood and lymph away from an injury site and replacing it with nutrient rich blood and fresh lymph.

• Question 169:

  Which of the following is typical of an acute injury?

  A. Scar tissue

  B. Keloids

  C. Inflammation

  D. Depression

  Correct Answer: C

  Explanation: All of the other options would indicate a chronic or later stage of an injury/disfunction. During an acute injury, inflammation would be most evident.

• Question 170:

  A pathogenic barrier is also known as a ____________.

  A. anatomic barrier

  B. physiologic barrier

  C. resistive barrier

  D. soft tissue barrier

  Correct Answer: C

  Explanation: A pathogenic barrier is also known as a resistive barrier, which is the first sign of resistance against a movement during a range of motion assessment.
