After hitting your thumb accidentally with a hammer, you quickly withdraw your hand. You do not feel pain for a short period of time. This sequence of events may be explained by the fact that the A. threshold of the receptor has been so greatly exceeded that the neuron does not pass the message to the brain B. neural impulse is so large that the brain is unable to interpret the signal because it is beyond the range of tolerance C. neural processing occurred in the spinal cord first, which caused you to quickly remove your thumb from further damage D. sensory receptors in the thumb were damaged by the blow and are unable to initiate a stimulus to the sensory nerve

Emotions

Emotions are biologically based psychological conditions caused by neurophysiological changes which are linked to different factors such as thoughts, emotions, behavioral responses, and pleasure or displeasure. These emotions are not similar to moods. The mood is an affective state. Mood depends upon several factors, such as weather, the environment, physiology, etc. Emotions can be beneficial or detrimental depending on the situation. Emotional reactions are simple. Emotional well-being is strongly affected by our well-being, and such feelings are private.
