The fingertips have a greater concentration of sensory receptors compared to the palms of the hands. This is why our fingertips are more sensitive to touch and able to detect fine details such as texture and temperature with precision.
The soles of your feet and the back of your neck have fewer sensory receptors compared to areas like your fingertips or face because they serve different functional purposes. The soles are primarily involved in balance and support, while the back of the neck has less exposure to stimuli. In contrast, areas like fingertips and lips require high sensitivity for tasks such as tactile discrimination and communication. This distribution of sensory receptors reflects the evolutionary adaptation to the specific needs of different body regions.
Yes, the tongue is generally considered to be more sensitive than the fingertips due to the high density of taste buds on the tongue. This allows for a greater ability to detect different tastes and flavors compared to the fingertips' ability to sense touch and pressure.
There is a greater concentration of Na plus outside and there is a greater concentration of K plus inside the cell. When the stimulus is delivered, the permeability of the membrane is changed, and Na plus diffuses into the cell, initiating the depolarization of the membrane.
The greater the concentration of salt in an aqueous solution, the higher the electrical conductivity. This is because, with a greater salt concentration, there are more ions available to serve as a path for electron transfer in the solution.

The fingertips of a figure skater spinning with her arms held straight out have a greater rotational speed compared to her shoulders. This is because the fingertips travel a greater distance in the same amount of time as the shoulders, leading to a higher angular velocity.

The concentration of dissociable OH- ions is a measure of the basicity of the substance. Greater the concentration of hydroxyl ions, greater is it alkaline.
the movement of particles from areas of greater concentration to area of lesser concentration.
Diffusion
There is a greater concentration of Na plus outside and there is a greater concentration of K plus inside the cell. When the stimulus is delivered, the permeability of the membrane is changed, and Na plus diffuses into the cell, initiating the depolarization of the membrane.
Passive Transport
The greater trochanter is a lateral structure of the femur.
The parts of the body that have the highest density of touch receptors are the places a person is the most ticklish. Under the arms, the bottom of the feet, and just under the rib area are all very ticklish places for everyone.

When comparing two solutions, the solution with the greater concentration of solute is called hypertonic. This means that it has a higher solute concentration compared to the other solution.
