Oral Cavity01:11

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
Physiology of the Gastrointestinal System I: Ingestion and Propulsion01:22

Physiology of the Gastrointestinal System I: Ingestion and Propulsion

The physiology of the gastrointestinal system begins with ingestion as food enters the mouth.
Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Salivary Glands and Saliva01:23

Salivary Glands and Saliva

The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...
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...
Tongue01:01

Tongue

The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...

Summary
This summary is machine-generated.

Chewing (mastication) is vital for maintaining brain health in older adults. Studies show impaired chewing causes memory loss, while chewing benefits cognitive function and brain health.

Area of Science:

  • Neuroscience
  • Gerontology
  • Oral Health

Background:

  • Masticatory (chewing) function is increasingly recognized for its role in maintaining neurocognitive function, particularly in the elderly.
  • Reduced masticatory ability, due to factors like toothlessness or soft diets, has been linked to learning and memory deficits in aged animals.
  • Occlusal disharmony can impair hippocampal memory processes through chronic stress, leading to similar pathological changes.

Purpose of the Study:

  • To investigate the link between masticatory function and neurocognitive function in the elderly.
  • To explore the impact of chewing on stress-induced cognitive impairments and hippocampal function.

Main Methods:

  • Review of recent studies on mastication and neurocognitive function.
  • Analysis of animal models demonstrating the effects of reduced mastication on learning, memory, and hippocampal pathology.
  • Examination of the effects of chewing on stress-induced suppression of long-term potentiation and hippocampal-dependent learning.

Main Results:

  • Reduced masticatory function is associated with learning and memory deficits and hippocampal pathology in aged animals.
  • Occlusal disharmony impairs hippocampal memory via chronic stress, inducing pathological changes.
  • Chewing effectively rescues stress-induced suppression of hippocampal long-term potentiation and learning impairments.

Conclusions:

  • Mastication plays a crucial role in maintaining neurocognitive function in the elderly.
  • Maintaining adequate chewing ability is important for preserving memory and hippocampal health.
  • Interventions aimed at improving masticatory function may benefit cognitive health in aging populations.
