Stimulus: Seeing your partner let go of the ruler. Response: Catching the ruler using your thumb and index finger. This is a voluntary action because it is a conscious action and is made according to the will of the individual who received the stimulus and is controlled by the brain. The distance moved by the ruler shows the time taken by the stude...
Stimulus: Intensity of light that enters the eye. Response: Change in size of the pupil. This is an involuntary action because this action occurs spontaneously without any conscious control or prior thoughts. The higher the intensity of light, the smaller the size of the pupil. This response can help protect the eye from injury.
Central nervous system and peripheral nervous system (a) Voluntary actions are conscious actions, carried out according to the wishes of a person and are controlled by the brain. Examples of controlled actions are reading, writing, speaking, eating, drinking, walking, running, exercising and singing. (b) Involuntary actions are spontaneous actions ...
Excess mucus is produced when a person suffers from a cold. This excess mucus will obstruct receptors from being stimulated by chemical substances in the air entering the nasal cavity.
A blind person uses the sensitivity of the fingertip to read Braille and sensitivity of the hand to detect vibrations of the walking stick when it hits objects to detect any nearby obstructions.
Tip of index finger. It has the largest number of receptors. Elbow. It has the least number of receptors. Touch receptor. Number of touch receptors and thickness of epidermis.
To ensure no other solutions remain and only the taste of one solution is detected during each attempt. All areas of the tongue can detect all tastes of the solutions. Both sides of the tongue are most sensitive towards taste because they have a large number of taste receptors. The middle part of the tongue is least sensitive to taste because it ha...
No. After the tongue is cleaned, the tongue will become more sensitive.
1. Without the nose being pinched. 2. Taste of the cordial drink is more easily detected using a combination of sense of taste and sense of smell. So that your partner does not use sense of sight to determine the taste of the cordial drink based on the colour such as purple for taste of grape, orange for taste of orange, yellow for taste of mango a...
