The cricopharyngeal spasms ("feeling that something is stuck") occur in the cricopharyngeal part of the inferior pharyngeal constrictor muscle, at the bottom of the throat. They cause muscle tension on the cricoid cartilage, leading to a globus feeling. Pharyngeal spasms, a more common source of a globus feeling, cause tension on the thyroid ...

The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (cranial nerve X) that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles. There are two recurrent laryngeal nerves, right and left. The right and left nerves are not symmetrical, with the left nerve looping under the aortic arch ...
The pharyngeal muscles are a group of muscles that form the pharynx, which is posterior to the oral cavity, determining the shape of its lumen, and affecting its sound properties as the primary resonating cavity. The pharyngeal muscles (involuntary skeletal) push food into the esophagus. There are two muscular layers of the pharynx: the outer ...
