Olfactory Receptors: Location and Structure

Olfactory Receptors: Location and Structure

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...

Taste Buds and Receptors

Taste Buds and Receptors

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,...

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Olfaction

Olfaction

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...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Nasointestinal feeding involves placing a tube through...

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Summary

Olfactory dysfunction, or impaired sense of smell, does not significantly impact sensory-specific satiety (SSS). This means that even with reduced smell, the decrease in food enjoyment during eating remains consistent.

Area of Science:

Neuroscience
Sensory Science
Gastroenterology

Background:

Odor stimuli are crucial for food flavor perception and influence eating behavior.
Olfactory dysfunction may alter eating patterns by affecting sensory-specific satiety (SSS).

Purpose of the Study:

To investigate the relationship between olfactory function and sensory-specific satiety (SSS).
To determine if impaired smell (hyposmia/anosmia) influences the decrease in food pleasure during consumption.

Main Methods:

Compared 34 participants with hyposmia/anosmia to 29 normosmic controls.
Participants repeatedly consumed a standardized food item to induce sensory satiation.
Assessed the development of sensory-specific satiety (SSS) in both groups.

Main Results:

Evidence of sensory-specific satiety (SSS) was observed in all participants, irrespective of their olfactory function.
Olfactory deficits did not significantly alter the experience or intensity of SSS.

Conclusions:

Sensory-specific satiety (SSS) appears to be independent of olfactory function.
Impaired sense of smell does not have a major impact on the development of SSS.
