When will sympathetic division works?
The sympathetic division of the autonomic nervous system is activated during "fight or flight" responses to stress or danger. This can occur in various situations, such as when encountering a threat, feeling anxious, or engaging in physical exertion.
What causes the activation of the parasympathetic division of the ANS?
The parasympathetic division of the autonomic nervous system is typically activated in situations of rest and relaxation, such as after a meal or during sleep. It counteracts the "fight or flight" response of the sympathetic division, promoting activities like digestion, conservation of energy, and restorative processes in the body. Stimulation of the parasympathetic nerves can also occur through activities like deep breathing, meditation, and gentle exercise.
Why does your face go red during exercise even though the sympathetic nervous system is activated which should divert your blood away from the skin and to your muscles instead?
The control of blood flow during exercise is more complicated than at first glance. At lower intensity exercise or at the start of exercise one of the main problems is heat. The blood carreis heat from the core to the skin allowing it to escape. During exercise heat would build up to dangerous levels is this system wasnt in place. However after more time the requirement of the muscles for oxygen outweighs the need to remove heat and so the blood flow to the skin is cut preserving more to flow to the the muscles.
Describe a situation or experience in which activation of the sympathetic and parasympathetic division has occurred?
During a stressful event like a car accident, the sympathetic division of the autonomic nervous system is activated, leading to the release of adrenaline and increased heart rate to prepare the body for fight or flight. Once the danger has passed, the parasympathetic division kicks in to slow down heart rate, promote digestion, and return the body to a resting state.
The sympathetic division of the autonomic nervous system is MOST likely to be activated when you are?
The sympathetic division of the autonomic nervous system is most likely to be activated during "fight or flight" situations when the body needs to respond quickly to a perceived threat or stressor. This can lead to a variety of physiological responses such as increased heart rate, dilated pupils, and the release of adrenaline to prepare the body for action.
When will sympathetic division works?
The sympathetic division of the autonomic nervous system is activated during "fight or flight" responses to stress or danger. This can occur in various situations, such as when encountering a threat, feeling anxious, or engaging in physical exertion.
What is the role of the system nervous?
During periods of stress or increased activity, the sympathetic division of the autonomic nervous system predominates. And during periods of rest, the parasympathetic division of the autonomic nervous system predominates
Does the sympathetic system cause vasodilation?
Yes, the sympathetic nervous system can cause vasodilation in certain situations, such as during exercise or in response to stress. This is because the sympathetic system releases certain neurotransmitters that can relax blood vessels and increase blood flow to muscles and other tissues.

What is watery discharge once during exercise?
when you stress your body ( Exercise), first parasympathetic nervous system get stimulated then sympathetic nervous system. Parasympathetic nervous system is responsible for body secretions ( watery nose, tears, stomach, mucus, saliva, etc). This is why first response of your exercise will be watery eyes and nose. After some time sympathetic nervous system kicks in and you become dry.

How do the parasympathetic and sympathetic nervous systems work together to regulate the body's response to stress and relaxation?
The parasympathetic and sympathetic nervous systems work together to regulate the body's response to stress and relaxation. The sympathetic system activates the "fight or flight" response during stress, increasing heart rate and releasing adrenaline. The parasympathetic system then helps the body relax after the stress has passed, slowing heart rate and promoting digestion. Together, they maintain balance in the body's response to different situations.
The sympathetic division of the autonomic nervous system is MOST likely to be activated when you are?

This can lead to a variety of physiological responses such as increased heart rate, dilated pupils, and the release of adrenaline to prepare the body for action.
How important is hydration for exercise performance and how can I ensure proper hydration during my workouts?
Hydration is very important for exercise performance as it helps regulate body temperature, maintain energy levels, and prevent dehydration. To ensure proper hydration during workouts, drink water before, during, and after exercise, listen to your body's thirst cues, and consider factors like sweat rate and exercise intensity when determining how much to drink.
What ancors the spindle in the cell cycle?
The centrosome is the organelle that anchors the spindle fibers in the cell during cell division. It helps to organize and regulate the movement of the chromosomes.
What is the result of sympathetic stimulation on the trachea?
Sympathetic stimulation of the trachea causes the trachealis muscle to relax, giving the trachea a large cross-sectional area. This allows increased air flow because of the increased diameter and less resistance.
