Olfactory Receptors: Location and Structure01:03

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...

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
Sensation01:21

Sensation

Sensory receptors are specialized neurons that respond to specific types of external stimuli, initiating the process known as sensation. This occurs when sensory input, such as light entering the eye, is detected by these receptors, causing chemical changes in the cells of the retina. These cells then convert the sensory stimulus into action potentials that are transmitted to the central nervous system, a process termed transduction.
Absolute thresholds can quantify the sensitivity of sensory...

Summary
This summary is machine-generated.

Sensory functions like touch, temperature, and taste decline with age. Older adults, especially men, showed reduced sensitivity across various sensory tests, indicating a widespread age-related sensory decrease.

Area of Science:

  • Gerontology
  • Neuroscience
  • Sensory Physiology

Background:

  • Sensory functioning often declines with advanced age.
  • Understanding these changes is crucial for maintaining quality of life in older adults.

Purpose of the Study:

  • To investigate age-related changes in somatosensory and gustatory thresholds.
  • To compare sensory sensitivity between younger and older healthy adults.

Main Methods:

  • Determined sensory thresholds (temperature, pain, touch, two-point discrimination, taste) in 178 healthy individuals (20-89 years).
  • Stimuli applied to glabrous (upper lip) and hairy (chin) skin.
  • Participants grouped into '< 45 yrs' and '≥ 65 yrs' for comparison.

Main Results:

  • Older adults exhibited elevated sensory thresholds across all tested modalities.
  • Males showed lower sensitivity than females for cool stimuli on the chin, touch, and sour taste.
  • Significant age-related declines were observed in both somatosensory and gustatory functions.

Conclusions:

  • Sensory thresholds increase with age, affecting multiple sensory systems.
  • Age-associated sensory decline impacts both somatosensation and gustation.
  • Sex differences in sensory sensitivity were noted, particularly in older age groups.
