2.
The mastoid process is the site of attachment for which muscle?
Correct Answer
A. Sternocleidomastoid
Explanation
The mastoid process is a bony prominence located behind the ear. The sternocleidomastoid muscle is attached to the mastoid process. This muscle originates from the sternum and clavicle and inserts into the mastoid process. It plays a key role in rotating and flexing the head and neck.
3.
Which suture separates the occipital and the two parietal bones?
Correct Answer

B. Occipital
C. Frontal
Explanation
4 bones in total.
5.
The viscerocranium is composed of 8 bones that make up the housing area for the brain.
Correct Answer
B. False
Explanation
Neurocranium is responsible for that. Viscerocranium makes up the face.
6.
Diploë is the name of the outer compact layer of a skull bone
Correct Answer
B. False
Explanation
Diploë is the middle spongy layer
7.
Emissary veins are contained at what level of the scalp?
Correct Answer
C. Loose connective tissue layer (Layer 4)
Explanation
Emissary veins connect to diploë veins. They are a high risk for intracranial transmission of infections.
8.
Which of the following are true about the pterion? (select 2)
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 together
Explanation
The area where the occipital, temporal, and parietal bones meet is called the Asterion
9.
A patient comes in with CSF dripping out of their nose. There is more likely an anterior basal skull fracture than a posterior basal skull fracture.
Correct Answer
A. True
Explanation
Slide 60. If its out of the ear it would most likely be posterior.
10.
Which muscle has attachment sites in the aponeurosis layer of the scalp?
Correct Answer
A. Occipitofrontalis
Explanation
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.
11.
Motor innervation to the face is carried out by which nerves? (Select 2)
Correct Answer(s)
A. CN V-3
C. CN 7
Explanation
V2 is sensory not motor.
12.
If during parotid gland surgery, the cranial nerve that traverses the parotid gland is severed, which of the following is true? (Select 2)
Correct Answer(s)
A. Paralysis of that side of the face will occur
B. The surgeon cut CN 7
Explanation
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.
13.
Which one do you like?
Correct Answer
A. Option 1
14.
The main motor portion of the facial nerve exits the cranium through the stylomastoid foramen.
Correct Answer
A. True
Explanation
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.
15.
Which facial muscle would be used to squint?
Correct Answer
A. Outer orbital portion of orbicularis oculi
Explanation
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.
16.
The two terminal branches of the external carotid artery are (select 2)
Correct Answer(s)
A. Maxillary
C. Superficial temporal
Explanation
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.
17.
Most of the blood supply to the face is from the ______ artery
Correct Answer
D. Facial
Explanation
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.
18.
The lacrimal, supratrochlear, and supraorbital arteries are branches of the external carotid artery
Correct Answer
B. False
Explanation
They are branches of the internal carotid artery
19.
The superficial temporal vein and maxillary vein come together to form the ____________
Correct Answer
A. Retromandibular vein
Explanation
This is one of the main drainage veins of the face (along with the facial vein and superficial temporal)
