What else can I help you with?
The division of autonomic nervous system that controls the series of physiological responses that are collectively called the fight or flight response.?
The sympathetic division of the autonomic nervous system controls the fight or flight response. This response triggers physiological changes that prepare the body to either confront or escape from a threatening situation, such as increased heart rate, dilated pupils, and enhanced alertness.
Why does stress make your pupils dilate?
The sphincter papillae controls pupil constriction and is governed by the parasympathetic nervous system. The dilator papillae controls pupil dilation and is governed the sympathetic nervous system. During the fight or flight response, only the sympathetic nervous system is stimulated. With the massive amounts of noradrenaline flowing through this system, the dilator papillae is innervated and the pupils dilate.
Do your pupils get smaller when you drink alcohol?
Yes, alcohol consumption can cause the pupils to constrict or become smaller. This is a normal physiological response to the depressant effects of alcohol on the central nervous system.
Name the two branches of the autonomic nervous system and describe the function of each branch?
The two branches of the autonomic nervous system are the sympathetic and parasympathetic nervous systems. The sympathetic nervous system is responsible for the "fight or flight" response, increasing heart rate, dilating pupils, and releasing adrenaline. The parasympathetic nervous system is responsible for the "rest and digest" response, slowing heart rate, constricting pupils, and aiding in digestion.
What do your pupils do when you go into shock?
Your pupils dilate. Your nervous system is in control of your pupils it affects the cranial nerve called the ocular nerve which causes it to not respond to light hence the dilation.
The nervous system called the fight or flight system is the?
The fight or flight response is a physiological reaction triggered by the sympathetic nervous system in response to a perceived threat or stressor. It prepares the body to either confront the threat or flee from it by increasing heart rate, dilating pupils, and releasing stress hormones like adrenaline. This response is essential for survival in dangerous situations.
What reponse is initiated by the sympathetic neuvous system?
The sympathetic nervous system initiates the "fight or flight" response in the body. This response prepares the body to deal with perceived threats or stressors by increasing heart rate, increasing blood flow to muscles, and dilating the pupils.
Reflex constriction of the pupils when viewing close objects?
This is called the near reflex or near response. It involves the reflexive constriction of the pupils, known as miosis, as well as convergence of the eyes and accommodation of the lens to allow for clear vision of close objects. This response is controlled by the parasympathetic nervous system.
What regulates the physiological changes that typically accompany an emotional response directly?
The autonomic nervous system, particularly the sympathetic and parasympathetic branches, regulates physiological changes that accompany an emotional response. The sympathetic nervous system is responsible for the "fight or flight" response by increasing heart rate, dilating pupils, and releasing adrenaline, while the parasympathetic nervous system helps return the body to a state of rest and relaxation after the emotional response subsides.
What not an antagonistic interaction of the sympathetic nervous system?
An example of a non-antagonistic interaction of the sympathetic nervous system is when it triggers the "fight or flight" response in response to a perceived threat. This response involves simultaneous activation of multiple physiological processes such as increased heart rate, dilated pupils, and release of adrenaline to help the individual respond to the threat effectively.
How does the sympathetic nervous system regulate the body's response to stress and danger?
The sympathetic nervous system is responsible for the body's "fight or flight" response to stress and danger. It activates various physiological changes, such as increasing heart rate, dilating pupils, and releasing adrenaline, to prepare the body to react quickly in threatening situations.
Name the division of autonomic nervous system responsible for pupillary light reflex?
The division of autonomic nervous system responsible for pupillary light reflex is the parasympathetic system. This is what causes the pupils to close down or open up in response to lighting conditions.
