When a nerve impulse reaches a synapse it jumps across the synaptic cleft like a spark because of its electrical nature?

The danger causes a rush of adrenalin, a hormone and chemical messenger in the brain, which in turn triggers these anxious reactions in a process called the “fight-or-flight’ response.

Which theory of the emotional process believes that our conscious experience of emotion determines physiological and Behavioural responses?
What is the main difference between the central nervous system and the peripheral nervous system?

What theory of emotion states that the emotion typically occurs before arousal and behavior?

The James-Lange theory of emotion asserts that emotions arise from physiological arousal.

When a nerve impulse reaches a synapse it jumps across the synaptic cleft like a spark because of its electrical nature?

When a nerve impulse reaches a synapse, it jumps across the synaptic cleft like a spark because of its electrical nature. Which of the following statements is true of a neural impulse? The process by which a neural impulse travels is electrochemical. Split-brain operations are primarily aimed at curing botulism.

What uses oxygen and nutrients to generate the energy needed to carry out the work of a neuron cell?

Mitochondria use oxygen and glucose to produce most of the cell’s energy. The brain consumes large amounts of ATP. The chemical energy stored in ATP is used to fuel most of the biochemical reactions of the neuron.

Why do things seem worse at night?

At night, if you are awake with worry, it is easy to work yourself into a state because your isolation and insignificance in the universe seems so much greater when everyone else is asleep. Also, it is against our natural circadian rhythms to be awake at this time because it unbalances hormones/chemicals in the brain.

Why am I most anxious at night?

There are many reasons why your anxiety may be worse at night. Daily stressors, poor sleep habits, and other health conditions can lead to increased anxiety and panic attacks at night. However, there are many treatments available that can help ease your anxiety and improve your quality of sleep.

Which theory of the emotional process believes that our conscious experience of emotion determines physiological and Behavioural responses?

Cognitive Appraisal Theory Richard Lazarus pioneered this theory of emotion. According to the Cognitive Appraisal Theory, thinking must occur before experiencing emotion. Thus, a person would first experience a stimulus, think, and then simultaneously experience a physiological response and the emotion.

Is involved in our experience of emotion?

The amygdala is involved in our experience of emotion and in tying emotional meaning to our memories. The hypothalamus regulates a number of homeostatic processes, including the regulation of body temperature, appetite, and blood pressure.

What initially causes a nerve impulse quizlet?

A stimulus leads to the movement of ions, which initiates an action potential in the neuron. A graded potential exists where the inside of the membrane is more positive and the outside is less positive. If enough sodium enters the cell, the action potential (nerve impulse) starts and is propagated over the entire axon.

What is the main difference between the central nervous system and the peripheral nervous system?

The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.

One of the concepts of evolutionary psychology is that not only physical traits but also many patterns of behavior, including social behavior, evolve and can be transmitted genetically from generation to generation.
