Olfactory Receptors: Location and Structure

10.5K
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...

Olfaction

40.5K
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...

Traumatic Brain Injury l: Introduction

25
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.

Physiology of Smell and Olfactory Pathway

13.1K
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...

Summary
This summary is machine-generated.

Mild head trauma in children can impact olfactory function, specifically odor detection thresholds. However, significant long-term olfactory impairment or loss is unlikely after such injuries.

Area of Science:

  • Neurology
  • Otolaryngology
  • Pediatrics

Background:

  • Olfactory impairment is associated with head injury.
  • Olfactory function testing may indicate frontal brain damage after trauma.

Purpose of the Study:

  • To assess the impact of mild head trauma on children's olfactory function.
  • To track olfactory function changes for up to one year post-trauma.

Main Methods:

  • 114 children with mild head trauma (Glasgow Coma Scale) were tested three times over one year.
  • Olfactory function was compared to age-matched healthy controls.
  • Tests included odor threshold and suprathreshold assessments.

Main Results:

  • Children with mild head trauma showed significantly lower odor thresholds than controls, though still within normal limits.
  • No significant differences were observed in suprathreshold testing between groups.
  • Olfactory threshold and discrimination scores did not change significantly over the one-year study period.

Conclusions:

  • Mild head trauma affects children's olfactory function, particularly odor detection.
  • Significant long-term olfactory deficits like hyposmia or anosmia are improbable following mild head trauma in children.
