Questions 27 through 30 refer to the figure below of an axial CT of the neck.Which arrow points to the SCM?
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
B. BExplanation
The arrow pointing to B indicates the SCM (sternocleidomastoid) muscle in the axial CT of the neck. The SCM is a large muscle located on both sides of the neck, running from the sternum and clavicle to the mastoid process of the skull. It is responsible for various movements of the head and neck, including rotation and flexion.Rate this question:

Questions 44 through 48 refer to the figure below of a coronal CT reformat of the neck.Which arrow points to the sternocleidomastoid musucle (SCM)?
- A.
A
- B.
B
- C.
C
- D.
D
- E.
E
Correct Answer
A. AExplanation
The correct answer is A. The sternocleidomastoid muscle (SCM) is a large muscle that runs diagonally across the neck. It originates from the sternum and clavicle and inserts on the mastoid process of the temporal bone. It helps to rotate and flex the head and neck. In the given figure, arrow A points to a structure that matches the description of the SCM muscle, making it the correct answer.Rate this question:

Questions 53 through 56 refer to the figure below of an axial CT of the inner ear.Which arrow points to the carotid canal?
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
D. DExplanation
The carotid canal is a bony canal in the skull that houses the carotid artery. In the given figure, arrow D is pointing towards a canal-like structure, which is likely to be the carotid canal. The other arrows (A, B, and C) are not pointing towards any canal-like structure in the inner ear.Rate this question:

Questions 40 through 43 refer to the figure below of a coronal, T1-weighted MRI of the piriform sinuses.Which arrow points to the aryepiglottic fold?
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
B. BExplanation
The correct answer is B. The arrow pointing to B indicates the aryepiglottic fold. The aryepiglottic fold is a fold of mucous membrane that extends from the arytenoid cartilage to the epiglottis. It helps to protect the airway during swallowing by closing off the laryngeal inlet.Rate this question:

The oropharynx extends between which two structures?
- A.
Soft palate and hyoid bone
- B.
Hard palate and hyoid bone
- C.
Soft palate and cricoid bone
- D.
Hard palate and cricoid cartilage
Correct Answer
A. Soft palate and hyoid boneExplanation
The oropharynx is a part of the throat that extends between the soft palate and the hyoid bone. The soft palate is the soft tissue at the back of the roof of the mouth, while the hyoid bone is a U-shaped bone located in the neck. These two structures mark the boundaries of the oropharynx.Rate this question:

Questions 40 through 43 refer to the figure below of a coronal CT reformat of the thoracic spine, post myelogram.Which arrow points to the thoracic pedicle?
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
B. BExplanation
The thoracic pedicle is a bony structure located on the posterior aspect of each vertebra in the thoracic spine. In the given figure, arrow B points to a structure that appears to be a bony prominence on the posterior aspect of a vertebra, which is consistent with the location of the thoracic pedicle. Therefore, arrow B is the correct answer.Rate this question:

Questions 23 through 26 refer to the figure below of an axial CT of the neck.Which arrow points to the aryepiglottic fold?
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
B. BExplanation
The arrow pointing to B is the correct answer because the aryepiglottic fold is a fold of mucous membrane that extends from the arytenoid cartilage to the epiglottis. In the given figure, arrow B is pointing to a structure that matches the description of the aryepiglottic fold.Rate this question:

Questions 36 through 39 refer to the figure below of a sagittal CT reformat of the pharynx.Which arrow point to the soft palate?
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
B. BExplanation
The correct answer is B because it is the only arrow that is pointing to the soft palate. The soft palate is a muscular structure located at the back of the roof of the mouth, and it helps to close off the nasal cavity during swallowing and speech. The other arrows are pointing to different structures in the pharynx, such as the uvula (A), the epiglottis (C), and the base of the tongue (D).Rate this question:

The cerebral hemispheres contain neural tissue arranged in numerous folds called:
- A.
Gyri
- B.
Sulci
- C.
Fisssures
- D.
Lobes
Correct Answer
A. GyriExplanation
The cerebral hemispheres contain neural tissue arranged in numerous folds called gyri. Gyri are the raised ridges on the surface of the brain that increase its surface area, allowing for more neural connections and higher cognitive functions. These folds play a crucial role in increasing the brain's processing power and efficiency by providing more space for neurons and their connections.Rate this question:

Which is a superficial muscle located on the posterior portion of the neck, that acts to elevate the scapula?
- A.
Splenius capitis
- B.
Rhomboid major
- C.
Posterior scalene
- D.
Trapezius
Correct Answer
D. TrapeziusExplanation
The trapezius muscle is a superficial muscle located on the posterior portion of the neck. It acts to elevate the scapula, which is the correct action described in the question. The other options, splenius capitis, rhomboid major, and posterior scalene, do not have the primary function of elevating the scapula.Rate this question:
