When a person is startled or sees a pleasurable object the pupils of the eye may dilate What division of the ANS is involved in this reaction Describe the nerve pathway involved?
The sympathetic division of the autonomic nervous system is involved in dilation of the pupils in response to startling or pleasurable stimuli. The pathway involves activation of the sympathetic chain ganglia, leading to release of norepinephrine from postganglionic fibers that act on the dilator pupillae muscle in the eye, causing pupil dilation.
What are the two divisions of the ANS?
The two divisions of the autonomic nervous system (ANS) are the sympathetic nervous system, which prepares the body for fight or flight responses, and the parasympathetic nervous system, which promotes rest and relaxation.
What organelle does not have ribosomes attached to it?
a nucleolusNucleolus make up the ribosomal compartments. But they are separated
The two divisions of the ANS normally have what relationship?
The two divisions of the autonomic nervous system (ANS), the sympathetic and parasympathetic divisions, typically have opposing functions. The sympathetic division is responsible for the "fight or flight" response, while the parasympathetic division promotes the "rest and digest" response. They work together to maintain balance and regulate bodily functions.
Does the ANS contain both sensory and motor neurons?
Yes, the Autonomic Nervous System (ANS) contains both sensory and motor neurons. Sensory neurons provide information from internal organs to the central nervous system, while motor neurons carry signals from the central nervous system to regulate involuntary bodily functions.
Which ANS subdivion is involved when you are startled and panicking?
The sympathetic division of the autonomic nervous system is involved in the "fight or flight" response that occurs when you are startled and panicking. This activation leads to an increase in heart rate, blood pressure, and respiration to prepare your body to respond to the perceived threat.
Which ANS subdivision is involved when you are eating potato chips?
parasympathetic
Which ans subdivision is involved when someone starts to panic?
The sympathetic nervous system is involved when someone starts to panic. This system triggers the body's "fight or flight" response, leading to increased heart rate, rapid breathing, and heightened alertness in response to a perceived threat.

If you are involved in a crash you are breaking the law if you do not stop true or false?
Ans: true
What subdivision of the PNS regulates the activity of the heart?
The subdivision of the peripheral nervous system (PNS) that regulates the activity of the heart is the autonomic nervous system (ANS). Specifically, the sympathetic division increases heart rate and contractility, while the parasympathetic division, primarily through the vagus nerve, decreases heart rate. Together, these divisions help maintain homeostasis in cardiac function.
Why are giraffes in captivity?
they are kept in captivity so that they can be away from predators ans so that they are less likely to become extinct as they can be involved in reeding programmes
What value is assigned to the type int variable ans in this statement if the value of p is 100 and q is 50?
It is not possible to answer this question without knowing the actual expression used in the assignment statement. The following are merely example expressions showing some of the values that could be assigned to ans: int ans, p=100, q=50; ans = p + q; // ans = 150 ans = p * q; // ans = 5000 ans = p - q; // ans = -50 ans = p / q; // ans = 2 ans = p % q; // ans = 0
