Understanding Nasal Insertion and Reflex Suppression

The video tutorial explores the use of an endoscope to follow a nail insertion into the nasal cavity, highlighting the anatomy of the nose and the potential risks involved, such as sneezing. It delves into how Jared suppresses his sneeze reflex through training, allowing him to perform the blockhead feat safely. The tutorial emphasizes the importance of understanding nasal structures and the dangers of involuntary responses during such procedures.

What tool does the team use to observe the nail insertion?

• Telescope

• Endoscope

• Microscope

• Stethoscope

What structure does the nail get caught on during insertion?

• Inferior turbinate

• Septum

• Nasal cavity

• Sinus

How does Jared manage to insert the screwdriver deeper without causing pain?

• By using anesthesia

• By inserting it quickly

• By maneuvering around sensitive areas

• By using a smaller screwdriver

What could happen if Jared sneezes with the screwdriver in his nose?

• It could break

• It could fall out

• It could enter the skull base

• It could cause a nosebleed

What is the initial action of a sneeze that could be dangerous for Jared?

• Sharp inhalation of air

• Closing of the eyes

• Sudden head movement

• Holding breath

Why does the team focus on Jared's right nostril?

• It's less sensitive

• He only uses it for insertion

• It's more flexible

• It's larger

What does the team discover about Jared's sneeze reflex?

• He doesn't have one

• He can control it

• It's stronger than normal

• It's triggered by light

How has Jared conditioned his nasal passage?

• By using medication

• By breathing exercises

• By repeated stimulation

• By avoiding allergens

What is the main skill Jared has developed to perform the blockhead feat?

• Breathing control

• Nasal flexibility

• Reflex suppression

• Pain tolerance

What makes watching Jared's performance disconcerting?

• The size of the objects

• The risk involved

• The speed of insertion

• The noise it makes
