Human Anatomy: Hyoid Bone Quiz

A bone located in the neck, that is not attached to any other bone, and is vital for tongue movement, speech, and swallowing.

The larynx is more than just your voice box. It protects the vocal cords, helps with coughing and straining, and closes the glottis during swallowing.

It is the largest cartilage of the larynx, forming the Adam's apple, and serves as the attachment point for muscles and ligaments related to speech.

Shaped like a signet ring, this strong cartilage forms the only complete ring in the airway. It's crucial for cricoid pressure during rapid sequence induction.

A flap of tissue that covers the opening of the larynx during swallowing, preventing food from entering the airway.

They protect the airway by stimulating sensory nerves, which send messages to the brain to initiate muscle movements like closing the vocal cords.

Laryngospasm is a spasm of the vocal cords, often due to a foreign object in the airway. It can be prevented by deepening general anesthesia or using local anesthetics.

The cough reflex is triggered by irritant gas, heat, or foreign objects in the upper and lower airways. It helps to clear the airway of these irritants.

Anatomical and physiological knowledge of the upper and lower airways helps improve patient safety, especially during procedures that involve the airway.

General anesthesia and paralysis can affect respiratory function, making understanding the airway vital for safe anesthetic procedures.

Understanding the function of the airway is essential for professional practice. It directly impacts how we manage airways during procedures.

A significant portion of complications and deaths during surgery are associated with airway dysfunction. Therefore, airway management is a critical aspect of patient safety.

This reflex is triggered by sensory nerves at the back of the tongue, uvula, tonsils, and the pharyngeal wall. It causes muscle contraction to expel foreign objects from the mouth.

BURP, or Backward-Upward-Rightward-Pressure, is applied to the thyroid cartilage to improve visualization of the vocal cords. It's not the same as cricoid pressure.

The thyroid cartilage, cricoid cartilage, and epiglottis are the three single cartilages in the larynx.

The arytenoid, corniculate, and cuneiform cartilages are paired structures in the larynx, each with a specific function.

The arytenoid cartilages help move the vocal cords by acting as attachment points for muscles and ligaments.

The corniculate cartilages sit atop the arytenoid cartilages, contributing to the connection of tissues in the larynx.

The cuneiform cartilages connect the epiglottis to other tissues within the larynx, contributing to its structure and function.

The tongue plays a significant role in breathing and swallowing. Its size and underlying muscle structure make it a potential obstruction during anesthesia.

Plan B is a backup plan used when facemask ventilation or intubation fails. It involves trying a supraglottic airway device (SAD) or other options like waking up the patient.

A supraglottic airway device (SAD) is a type of airway device that is placed in the pharynx to maintain oxygenation.', 'term': 'What is a SAD, and why is it used?

When SAD ventilation fails, options include waking the patient, intubating through the SAD, or proceeding without intubation, possibly leading to tracheostomy or cricothyroidotomy.

Plan A is the standard approach to airway management, involving facemask ventilation and tracheal intubation. It can be complicated by factors like mouth opening, obesity, and trauma.

It is important to consider different laryngoscope types to find the most suitable option for each patient, as well as positioning the patient correctly for better visualization.
