Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

10.8K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Olfaction01:25

Olfaction

47.6K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Physiology of Smell and Olfactory Pathway01:20

Physiology of Smell and Olfactory Pathway

11.5K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
The olfactory...

Assessment of the Mouth01:26

Assessment of the Mouth

812
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.

Psychosexual Stages of Personality: Oral01:16

Psychosexual Stages of Personality: Oral

2.2K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.
Weaning, typically occurring...

Taste Buds and Receptors01:20

Taste Buds and Receptors

4.1K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Summary
This summary is machine-generated.

Cheiro-Oral (COS) Syndrome, a rare neurologic condition, causes sensory disturbances in the mouth and hand, often due to thalamic stroke. Early recognition in emergency departments is crucial for accurate diagnosis and treatment.

Area of Science:

  • Neurology
  • Emergency Medicine

Background:

  • Cheiro-Oral (COS) Syndrome is a rare neurologic condition.
  • It presents with sensory disturbances affecting the peri-oral area and upper extremity, typically the hand.

Observation:

  • The contralateral thalamus is the most commonly implicated brain region.
  • Causes include ischemic/hemorrhagic strokes, tumors, hematomas, aneurysms, and infections.

Findings:

  • The unusual symptom presentation can lead to misdiagnosis and delayed workup.
  • This condition is rarely reported in emergency medicine literature despite likely emergency department presentation.

Implications:

  • Accurate and timely diagnosis of COS in the emergency department is essential.
  • Increased awareness can improve patient outcomes for this rare neurologic syndrome.
