How does the activation of the sympathetic nervous system impact the body's response to stress?
The activation of the sympathetic nervous system during stress triggers the "fight or flight" response in the body. This leads to increased heart rate, elevated blood pressure, and the release of stress hormones like adrenaline, preparing the body to react quickly to the perceived threat.
What happens during the respiratory cascade?
Your breasts get saggy, and they detieriate
What happens During an asthma attack a person's respiratory passages become?
During an asthma attack, a person's respiratory passages become narrowed and inflamed
What happens to catalysts during chemical reactions?
it lowers the amout of activation energy needed to start the reaction.
Can the sympathetic and parasympathetic nervous system be active at the same time?
Yes, the sympathetic and parasympathetic nervous systems can be active simultaneously, a phenomenon known as autonomic co-activation. This occurs in certain situations where the body requires a balance of functions, such as during stress when the sympathetic system prepares the body for action, while the parasympathetic system may still manage functions like digestion. The two systems often work in opposition to regulate bodily responses, but their simultaneous activation can help fine-tune responses to complex situations.
What happens to heart rate during respiratory depression?
your hart would stop and you would die
Is dry mouth sympathetic?
Yes, dry mouth, or xerostomia, can be associated with sympathetic nervous system activation. The sympathetic system can inhibit saliva production, leading to a feeling of dryness. This response may occur during stress or anxiety, where the body prepares for "fight or flight" situations, diverting resources away from non-essential functions like saliva secretion. Additionally, certain medications that stimulate the sympathetic nervous system can contribute to dry mouth.
Which glands are targeted by the sympathetic nerves?
The sympathetic nerves primarily target the adrenal medulla, stimulating the release of catecholamines like adrenaline and noradrenaline. Additionally, they influence various glands throughout the body, including sweat glands and salivary glands, to modulate physiological responses during stress. This activation helps prepare the body for the "fight or flight" response.
What is Sympathetic action of the pupil?
Sympathetic action of the pupil refers to the process by which the pupil dilates, or enlarges, in response to sympathetic nervous system activation. This dilation occurs during the "fight or flight" response, allowing more light to enter the eye, which enhances visual acuity in threatening situations. The neurotransmitter norepinephrine plays a key role in this action by stimulating the dilator muscles of the iris. This response is part of the body's broader physiological reaction to stress or danger.
What diseases patient has pneumonia which causes the skin to have a bluish color?
This happens during pneumonia due to a lack of oxygen through respiratory failure.
Does the Sympathetic nervous system stimulation raise blood sugar?
No sypathetic nervous system does not raise blood sugar. It decreaces blood sugar concentration by providing that sugar(glucose) as an energy source to muscles which are under fight or flight response.
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.
