Deglutition01:25

Deglutition

Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...
Esophageal Achalasia01:27

Esophageal Achalasia

Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
Upper GI Series: Barium Swallow01:24

Upper GI Series: Barium Swallow

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...

Physiology of the Gastrointestinal System I: Ingestion and Propulsion

The physiology of the gastrointestinal system begins with ingestion as food enters the mouth.
Bulimia Nervosa01:30

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Summary
This summary is machine-generated.

Dysfunctional swallowing, even in young adults, can negatively impact posture by increasing body sway and energy expenditure, similar to cognitive tasks. This effect is more pronounced during forced swallowing.

Area of Science:

  • Neurology
  • Physiology
  • Biomechanics

Context:

  • Swallowing is a fundamental physiological function established early in development.
  • Incomplete maturation can lead to persistent dysfunctional swallowing.
  • Existing research links dental occlusion changes and lingual dysfunction to postural issues.

Purpose:

  • To investigate the direct impact of dysfunctional swallowing on body posture.
  • To determine if lack of dental contacts and lingual dysfunction during swallowing affect posture.
  • To compare postural effects of functional vs. dysfunctional swallowing.

Summary:

  • A study involving 20 young adults compared postural stability during mandibular rest, cognitive tasks, functional swallowing, and dysfunctional swallowing.
  • Postural sway and energy expenditure were measured using a stabilometric platform and electromyography of the masseter and sternocleidomastoid muscles.
  • Results indicate that dysfunctional swallowing significantly increases postural oscillations and energy demands, comparable to cognitive tasks.

Impact:

  • Dysfunctional swallowing can be a significant factor influencing body posture and postural control.
  • Findings highlight the intricate connection between oral motor functions and overall body stability.
  • This research may inform therapeutic interventions for individuals with swallowing disorders and associated postural problems.
