Question:

A 56 year old male with a history of hypertension, hyperlipidemia and obesity presents with substernal chest pain for the past 3 hours. What is the most likely diagnosis?

Answer:

This patient is likely undergoing an acute myocardial infarction (MI), meaning that there is a blockage of one of his coronary arteries. The coronary arteries are the arteries that supply blood to the heart tissue itself. The heart requires a considerable amount of blood (and oxygen carried by the blood) in order to work effectively. If there is a decrease in blood flow to an area of the heart, chest pain will occur. When the patient presents to the hospital, the patient will have basic lab tests drawn, as well as an electrocardiogram (ECG) and possibly an echocardiogram.

Answer:

The external branch of the superior laryngeal nerve supplies the cricothyroid muscle. The superior laryngeal nerve is a branch of the vagus nerve. The other half of the superior laryngeal nerve (the internal branch) supplies sensory fibers to the laryngeal mucosa. All other intrinsic laryngeal muscles are supplied by the recurrent laryngeal nerve.
