Pharynx01:20

Pharynx

8.3K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Anatomy of Respiratory System I: Upper Respiratory Tract

6.2K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

Larynx01:21

Larynx

5.8K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Cranial Nerves: Types Part II01:22

Cranial Nerves: Types Part II

5.8K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
Facial Nerve (Cranial Nerve VII)
Cranial nerve VII, or the facial nerve,...

Chronic Pharyngitis01:23

Chronic Pharyngitis

14.1K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Oral Cavity01:11

Oral Cavity

3.6K
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...

Area of Science:

  • Gastroenterology and Otolaryngology
  • Physiology and Anatomy
  • Surgical Management

Background:

  • The upper oesophageal sphincter (UES) and cricopharyngeus muscle play a critical role in swallowing.
  • Dysfunction in these areas can lead to significant swallowing difficulties (dysphagia).
  • Current research is continually refining our understanding of their complex physiology.

Purpose of the Study:

  • To review current research on upper oesophageal sphincter (UES) and cricopharyngeus muscle function.
  • To explore how a deeper understanding of UES physiology can improve patient management.
  • To synthesize new findings regarding UES and cricopharyngeus dynamics.

Main Methods:

  • Review of recent manometry studies.
  • Analysis of combined fluoromanometry data.
  • Examination of anatomical studies and clinical outcomes.

Main Results:

  • New insights into the dynamic function of the UES and cricopharyngeus are emerging.
  • The response of the UES to injury, reflux, and surgical interventions is being elucidated.
  • Surgical treatment for cricopharyngeus noncompliance shows sustained benefits in approximately 75% of patients.

Conclusions:

  • UES and cricopharyngeus function is intricate and influenced by various factors including posture, reflux, aging, and medical interventions.
  • A comprehensive understanding of UES triggers and responses is essential for effective dysphagia therapy.
  • Clinicians can optimize treatment selection for dysphagic patients through advanced knowledge of UES physiology.
