The mastoid process is the site of attachment for which muscle?
- A.
Sternocleidomastoid

Correct Answer(s)
A. A fracture here can cause damage to the middle meningeal artery
C. It is an area where the temporal, frontal, parietal, and sphenoid come togetherExplanation

Which muscle has attachment sites in the aponeurosis layer of the scalp?
- A.
Occipitofrontalis
- B.
Sternocleidomastoid
- C.
Platysma
- D.
Omohyoid
Correct Answer
A. OccipitofrontalisExplanation
The occipitofrontalis muscle is a broad muscle that covers the top of the skull and forehead. It is responsible for raising the eyebrows, wrinkling the forehead, and retracting the scalp. The aponeurosis layer of the scalp is a strong, fibrous sheet of connective tissue that covers the skull. The occipitofrontalis muscle has attachment sites in this layer, allowing it to move and manipulate the scalp.Rate this question:

If during parotid gland surgery, the cranial nerve that traverses the parotid gland is severed, which of the following is true? (Select 2)
- A.
Paralysis of that side of the face will occur
- B.
The surgeon cut CN 7
- C.
The surgeon cut CN 5
- D.
The patient will experienced loss of sensation in that side of the face
Correct Answer(s)
A. Paralysis of that side of the face will occur
B. The surgeon cut CN 7Explanation
If the cranial nerve that traverses the parotid gland (CN 7) is severed during parotid gland surgery, it will result in paralysis of that side of the face. This is because CN 7, also known as the facial nerve, innervates the muscles responsible for facial expressions. Therefore, cutting this nerve will lead to the loss of voluntary movement on the affected side of the face. However, it is important to note that the question does not provide information about CN 5, so we cannot make any conclusions regarding its involvement in this scenario.Rate this question:

The main motor portion of the facial nerve exits the cranium through the stylomastoid foramen.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The main motor portion of the facial nerve exits the cranium through the stylomastoid foramen. This is true because the stylomastoid foramen is a small opening located in the skull, specifically in the temporal bone. It serves as the pathway for the facial nerve, which controls the muscles of facial expression. Exiting through this foramen allows the facial nerve to innervate the muscles of the face and contribute to facial movements.Rate this question:

Which facial muscle would be used to squint?
- A.
Outer orbital portion of orbicularis oculi
- B.
Inner palpebral portion of orbicularis oculi
- C.
Lacrimal portion of orbicularis oculi
- D.
Orbicularis oris
Correct Answer
A. Outer orbital portion of orbicularis oculiExplanation
The outer orbital portion of the orbicularis oculi muscle would be used to squint. This muscle surrounds the eye and is responsible for closing the eyelids tightly. When someone squints, they are narrowing their eye opening by contracting this muscle.Rate this question:

The two terminal branches of the external carotid artery are (select 2)
- A.
Maxillary
- B.
Facial
- C.
Superficial temporal
- D.
Ascending pharyngeal
Correct Answer(s)
A. Maxillary
C. Superficial temporalExplanation
The external carotid artery is a major blood vessel that supplies blood to the face and neck. It gives rise to several branches, two of which are the maxillary artery and the superficial temporal artery. The maxillary artery supplies blood to the deep structures of the face, such as the muscles and bones, while the superficial temporal artery supplies blood to the scalp and the side of the head. Therefore, the correct answer is Maxillary and Superficial temporal.Rate this question:
-

Most of the blood supply to the face is from the ______ artery
- A.
Maxillary
- B.
Lingual
- C.
Superficial temporal
- D.
Facial
Correct Answer
D. FacialExplanation
The facial artery is the correct answer because it is the main blood supply to the face. It arises from the external carotid artery and branches out to supply blood to various structures in the face, including the muscles, skin, and other tissues. The maxillary artery supplies blood to the deep structures of the face, while the lingual artery supplies blood to the tongue. The superficial temporal artery supplies blood to the scalp and temporal region. However, in terms of blood supply to the face as a whole, the facial artery is the primary source.Rate this question:
