Questions 36 through 39 refer to the figure below of a sagittal CT reformat of the pharynx.Which arrow points to the hyoid bone
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
C. CExplanation
The correct answer is C because it is pointing directly to the hyoid bone in the sagittal CT reformat of the pharynx. The hyoid bone is a U-shaped bone located in the neck, just above the larynx. It does not articulate with any other bones and serves as a point of attachment for several muscles involved in swallowing and speech production.Rate this question:

What muscle forms the boundary for the anterior and posterior triangles in the neck?
- A.
Platysma
- B.
Middle scalene
- C.
Sternocleidomastoid
- D.
Trapezius
Correct Answer
C. SternocleidomastoidExplanation
The sternocleidomastoid muscle is a large muscle in the neck that runs diagonally from the sternum and clavicle to the mastoid process of the skull. It forms the boundary for the anterior and posterior triangles in the neck. The anterior triangle is formed by the midline of the neck, the mandible, and the anterior border of the sternocleidomastoid muscle, while the posterior triangle is formed by the posterior border of the sternocleidomastoid muscle, the clavicle, and the anterior border of the trapezius muscle. Therefore, the sternocleidomastoid muscle is the correct answer.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 thyroid carilage?
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
D. DExplanation
The correct answer is D. The arrow pointing to D indicates the location of the thyroid cartilage. The thyroid cartilage is a prominent structure in the neck and is commonly referred to as the "Adam's apple". In this MRI image, it appears as a bright white structure, indicating its high water content. The other arrows (A, B, and C) do not point to the thyroid cartilage and may represent different anatomical structures in the image.Rate this question:

Which sutrue is located posterior in the cranium and joins the occipital and parietal bones?
- A.
Squamous
- B.
Coronal
- C.
Sagittal
- D.
Lambdoidal
Correct Answer
D. LambdoidalExplanation
The lambdoidal suture is located posterior in the cranium and joins the occipital and parietal bones. This suture is named after its shape, which resembles the Greek letter "lambda." It is a dense, fibrous joint that helps to connect and stabilize these two bones at the back of the skull.Rate this question:

Questions 9 through 11 refer to the figure below of a sagittal MR of the lumbar spine.Which arrow point to the nucleus pulposus?
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
D. DExplanation
The correct answer is D because it is pointing to the central portion of the intervertebral disc, which is where the nucleus pulposus is located. The nucleus pulposus is a gel-like substance within the disc that helps to absorb shock and provide cushioning between the vertebrae.Rate this question:

Which is the most posterior portion of the corpus callosum?
- A.
Genu
- B.
Body
- C.
Rostrum
- D.
Splenium
Correct Answer
D. SpleniumExplanation
The splenium is the most posterior portion of the corpus callosum. It is located at the back of the brain and connects the left and right cerebral hemispheres. The corpus callosum plays a crucial role in facilitating communication between the two hemispheres, allowing for the transfer of information and coordination of functions.Rate this question:

Which cartilage forms the base of the larynx?
- A.
Thryroid
- B.
Epiglottis
- C.
Cricoid
- D.
Arytenoid
Correct Answer
C. CricoidExplanation
The cricoid cartilage forms the base of the larynx. It is a ring-shaped cartilage located just below the thyroid cartilage. The cricoid cartilage provides support and stability to the larynx, allowing it to function properly during speech and swallowing. It also plays a role in controlling the tension of the vocal cords.Rate this question:

- A.
A
- B.
B
- C.
C
- D.
D
- E.
E
Correct Answer
D. DExplanation
In the given figure, arrow D points to the esophagus. The esophagus is the muscular tube that connects the throat (pharynx) to the stomach. It is located posterior to the trachea and can be identified in the image by its position and shape, as well as its proximity to other structures such as the thyroid gland and the vertebral column.Rate this question:

The laminae of the thyroid cartilage unite anteriorly to form the:
- A.
Laryngela prominence
- B.
Superior thyroid notch
- C.
Superior horn
- D.
Inferior horn
Correct Answer
A. Laryngela prominenceExplanation
The laminae of the thyroid cartilage unite anteriorly to form the laryngeal prominence. This is also known as the Adam's apple, a visible protrusion in the neck, more prominent in males due to hormonal differences. The laryngeal prominence plays a role in protecting the vocal cords and is involved in voice production.Rate this question:

Questions 37 through 39 refer to the figure below of an axial CT of the temporal bone.Which arrow points to the sphenoid sinus?
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
C. CExplanation
The correct answer is C. In the figure, arrow C points to the sphenoid sinus. The sphenoid sinus is located in the sphenoid bone, which is one of the bones of the skull. It is situated behind the ethmoid sinuses and below the sella turcica. The sphenoid sinus is an air-filled cavity that plays a role in the drainage of mucus and the resonance of the voice.Rate this question:

The thyroid gland is located at the level of which laryngeal cartilage?
- A.
Cricoid
- B.
Coricorid
- C.
Epiglottis
- D.
Cuneiform
Correct Answer
A. CricoidExplanation
The correct answer is cricoid. The cricoid cartilage is a ring-shaped cartilage located at the level of the thyroid gland in the neck. It is situated just below the thyroid cartilage, also known as the Adam's apple. The cricoid cartilage helps to support and protect the larynx and plays a crucial role in the production of sound during speech.Rate this question:
