What is the purpose of the sympathetic nervous system in the human body?
The purpose of the sympathetic nervous system in the human body is to activate the "fight or flight" response in times of stress or danger. This system helps prepare the body for action by increasing heart rate, dilating airways, and redirecting blood flow to muscles.
How many cells in a nervous system?
You could say there are 2, The Central Nervous System(CNS), & the Peripheral Nervous System (PNS).To be more inclusive, here is a list of human nervous systems:The Central Nervous System (CNS), the Peripheral Nervous System (PNS),the Somatic Nervous System (SNS), the Autonomic Nervous System, the Sympathetic Nervous System, and the Parasympathetic Nervous System.That would make a total of 6, although the Sympathetic and Parasympathetic are parts of the Autonomic Nervous system, which could mean a total of 4, and the Autonomic is itself a part of the Peripheral Nervous System, which would bring the total back to 2.The Central Nervous System is comprised of the brain and the spinal cord;the Peripheral Nervous System connects the CNS to other parts of the body, and is comprised of the Somatic Nervous System and the Autonomic Nervous System;the Somatic Nervous System includes all the nerves controlling the body's muscular system, and sensory nerves;the Autonomic Nervous System consists of motor neurons which control internal organs, and is comprised of two sub-systems, the Sympathetic Nervous System, and the Parasympathetic Nervous System;the Sympathetic Nervous System is involved in the fight-or-flight response, and the Parasympathetic Nervous System is involved in relaxation.
How do neurons function in the human brain and what role do they play in transmitting information throughout the nervous system?
Neurons are the building blocks of the human brain and nervous system. They function by transmitting electrical signals and chemical messages to communicate with other neurons. Neurons play a crucial role in transmitting information throughout the nervous system by forming complex networks and pathways that allow for the relay of sensory information, motor commands, and cognitive processes.
What are the two divisions partof the human nervous system?
The two divisions of the human nervous system are the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which consists of all the nerves outside the CNS that connect it to the rest of the body.
What might happen to the human body if one part of the nervous system fails to carry out its function properly?
If a part of the nervous system fails to carry out its function properly, it can lead to a variety of symptoms depending on the affected area. For example, if the autonomic nervous system is disrupted, it can result in issues with heart rate, blood pressure, digestion, and body temperature regulation. If the peripheral nervous system is affected, it can lead to muscle weakness, numbness, tingling, and pain in the affected area.
The two major divisions of the human nervous system are?
The two major divisions of the human nervous system are the central nerves and the peripheral nerves.
What is the purpose of the sympathetic nervous system in the human body?
The purpose of the sympathetic nervous system in the human body is to activate the "fight or flight" response in times of stress or danger. This system helps prepare the body for action by increasing heart rate, dilating airways, and redirecting blood flow to muscles.

What is the difference between a human nervous system and a jellyfish nervous system?
A human nervous system is much more complex. Unlike a human a jellyfish does not have a central nervous system.
Is the sympathetic nervous system same as central nervous system?
Autonomic nervous system is that part of the nervous system that controls the body function that are not consciously controlled by the human brain like breathing, heartbeat, and digestive processes. Autonomic nervous system is a part of the peripheral nervous system. It works along with the somatic nervous system to regulate the body functions.
What is the division of the autonomic nervous system is said to function during resting conditions?
human anatomy
Which of the following systems does alcohol have the most immediate effect on in the human body?
The central nervous system is the system in the human body that alcohol has the most immediate effect on. Alcohol affects neurotransmitter function, leading to changes in mood, behavior, and cognitive function.

What system does the human brain belong to?
The human brain belongs to the nervous system.
In what order does the human body function?
It would depend on which body system you are talking about. i.e. nervous, digestive, etc.
What nervous system is responsible for the involuntary processes of the human body?
You are probably referring to "involuntary body functions" - and the answer would be the autonomic nervous system. This system could be further divided into the sympathetic nervous system and the parasympathetic nervous system.
