Techniques of therapeutic communication I: Active Listening, Sharing Observations, Validation, and Using Touch01:15

Techniques of therapeutic communication I: Active Listening, Sharing Observations, Validation, and Using Touch

7.9K
The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...

Tactile and Chemical Senses01:27

Tactile and Chemical Senses

1.5K
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

Design Example: Resistive Touchscreen

934
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

Tangent Line01:26

Tangent Line

1.0K
In differential calculus, understanding how a quantity changes at an exact point is central to interpreting dynamic systems. This can be illustrated by analyzing a car traveling along a winding road. The car’s trajectory is represented as a continuous curve, and the direction in which it moves at any instant is given by the tangent to that curve. In contrast, the secant line, intersecting the curve at two points, captures how the car’s position changes over an interval — an...

The Tongue and Taste Buds00:49

The Tongue and Taste Buds

34.7K
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

Atomic Force Microscopy01:08

Atomic Force Microscopy

3.1K
Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Area of Science:

  • Neuroscience
  • Sensory Biology
  • Mechanobiology

Background:

  • Mechanosensitive sensory neurons in dorsal root and trigeminal ganglia mediate touch, proprioception, and pain.
  • Mechanotransduction, the process of converting mechanical stimuli into cellular signals, involves diverse proposed mechanisms.

Purpose of the Study:

  • To describe the properties of mechanosensitive channels in sensory neurons.

Main Methods:

  • Review of proposed mechanotransduction mechanisms.
  • Description of mechanosensitive channel properties.
  • Discussion of molecular candidates.
  • Analysis of imaging studies on central nervous system activity related to touch and pain.

Main Results:

  • Mechanosensitive channels in sensory neurons exhibit diverse properties.
  • Multiple direct and indirect mechanisms, including ion channels and specialized end organs, contribute to mechanotransduction.
  • Imaging studies reveal central nervous system activity associated with touch, pain, and allodynia.

Conclusions:

  • Mechanotransduction involves a complex interplay of ion channels, intracellular mediators, and specialized sensory structures.
