Coordinate mapping is a method of documenting salient features of hyolaryngeal biomechanics in the pharyngeal phase of swallowing. This methodology uses image analysis software to record coordinates of anatomical landmarks. These coordinates are imported into an excel macro and translated into kinematic variables of interest useful in dysphagia research.

Upper GI Series: Barium Swallow
0 Views •
2025
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues. Purpose and Procedure Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

2015
We outline a protocol that implements both in vivo and ex vivo approaches to study ovarian cancer colonization of peritoneal adipose tissues, particularly the omentum. Furthermore, we present a protocol to quantitate and analyze immune cell-structures in the omentum known as milky spots, which promote metastases of peritoneal adipose.
FAQs
Sensory feedback helps coordinate feeding by providing information about food handling and bolus movement. This input works with integrated neural control to adjust the actions of the teeth, tongue, pharyngeal muscles, and esophagus. The coordination is important because the bolus must be prepared for transport while swallowing movements remain precisely timed to protect the airway.
The tongue positions food so the teeth can mechanically fragment it effectively, while saliva lubricates the material as it is processed. Together, these functions help produce a manageable bolus rather than leaving food in poorly organized pieces. Their cooperation links mechanical breakdown with the later transport demands of swallowing and supports efficient digestion.
Mastication prepares food by reducing its size and organizing it into a bolus, whereas swallowing moves that bolus through the mouth, pharynx, and esophagus toward the stomach. The two processes therefore have different immediate roles, but they operate as a coordinated sequence. Effective preparation supports transport, while timed swallowing protects the airway.
Clinical assessment can consider how effectively the mouth prepares a bolus and how well the subsequent swallowing movements coordinate transport and airway protection. Because these functions depend on sensory feedback and neural control, assessment also provides context for identifying disrupted coordination. Such information is relevant to understanding feeding difficulties and disorders such as dysphagia.
Dysphagia involves difficulty related to swallowing, making the coordinated actions of the tongue, pharyngeal muscles, and esophagus important targets for clinical understanding. Studying normal feeding biology provides a framework for evaluating disrupted bolus transport and airway protection. That framework can inform rehabilitation approaches designed to address impaired function and support safer feeding.
Food design can take into account the need for material that the teeth and tongue can organize into a manageable bolus and that swallowing movements can transport safely. Saliva-related lubrication and airway protection are also relevant biological considerations. Applying this knowledge connects feeding physiology with the development of foods intended to reduce swallowing-related risks.
