What is the CN V3 (mandibular)?
This suture lies between the two parietal bones at the top of the skull.
What is the sagittal suture?
These competitive antagonists bind to the alpha subunits of nicotinic receptors, preventing channel opening and are clinically used to induce muscle relaxation during surgery.
What are non-depolarizing neuromuscular blockers?
This cranial suture separates the frontal bone from the parietal bones (1)
What is the coronal suture?
This notch sits at the superior border of the manubrium of the sternum (6).
What is the jugular notch?
These are the motor branches of facial nerve.
What are temporal, zygomatic, buccal, mandibular, cervical?
These nerves are in the walls of the cavernous sinus?
What are the CN III, IV, V1 and V2?
Organophosphates like malathion and sarin share this phenomenon where the phosphorylated complex becomes stronger over time.
What is aging?
This space is posterior to the nasal cavity and visible on imaging, located with the mastoid portion of the temporal bone (2).
What are the mastoid air cells?
Three bones, the superior, middle, and inferior nasal conchae, make up this structure of the lateral nasal wall.
What are the turbinates?
The submandibular triangle houses all of these.
What are the submandibular lymph nodes, hypoglossal n (CN XII)
What is located at the following label (7)?
Condylar Process
Because it is a quaternary amine that does not cross the blood-brain barrier, this carbamate acetylchlinesterase inhibitor avoids central nervous system side effects while treating myasthenia gravis

In this sagittal T1-weighted MRI, the red marking indicates this fibrocartilaginous structure of the temporomandibular joint (3).
BONUS: Is the mouth open or closed?
What is the disc?
BONUS: Closed
This ossicle is the smallest bone in the human body (5).
What is the stapes (stirrup)?
Oral sphincter; closes oral fissure; compresses and protrudes lips (kissing me :)) or resists distension (blowing me ;))
What is the orbicularis oris?
What we looking at right here (8)?
Anterior fontanelle
Respitory arrest from acetylcholinesterase inhibitor toxicity can arise through four different mechanisms. Name them.
What are bronchoconstriction, bronchorrhea, central respitory depression, and paralysis of respitory muscles?
When evaluating head and neck musculature, name the different modalities that can assess blood flow and vascular anatomy.
What are Fluoroscopic Catheter Angiography, MR Angiography, CR Angiography, and Triplex Doppler Ultrasound?
A blow to this junction of the frontal, parietal, temporal, and sphenoid bones can rupture the middle meningeal artery.
BONUS: What does this rupture lead to?
What is the pterion?
BONUS: What is an epidual hematoma?
What are the mastoid, submandibular, submental, parotid, retropharyngeal lymph nodes?
What is the clinical use of succinylcholine?
