The parasympathetic system counteracts the sympathetic system.
It regulates breathing and heartbeats

What is the best definition of the peripheral nervous system?
The peripheral nervous system consists of all the nerves outside of the brain and spinal cord. It connects the central nervous system to the rest of the body and controls voluntary movements as well as involuntary functions like digestion and heart rate.
Describe breifly the nervous system?
The nervous system is a complex network of cells that transmit signals throughout the body. It is divided into the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves outside the brain and spinal cord). It is responsible for controlling and coordinating all bodily functions and responses.
If you're a psychologist who is fascinated by how alcohol acts on the nervous system to alter perception what perspective do you follow?
You are likely approaching it from a biological perspective, as you are interested in how alcohol affects the nervous system. This perspective focuses on how physiological processes, such as brain chemistry and neurotransmitters, influence behavior and mental processes.
What system maintains homeostasis in the body?
In a healthy person, all the body systems are homeostatic. The main system that regulates homeostasis is the autonomic branch of the peripheral nervous system. The main gland of homeostasis is the hypothalamus and the major organs are the kidneys.
What is an analogy for the endocrine system?
The best way to compare the nervous system and the endocrine system is to compare the characteristics of speed, specificity and plasticity (ability to respond and change permanently, particularly with respect to strength and speed.) The nervous system uses rapid electrical signals along nerve axons. Chemical signals are used between nerve cells at synapses. Although this chemical transmission is slower than electrical transmission, synapses are important in transmission between nerve cells. The endocrine system uses hormones, which are secreted into and transported to their target cells via the circulation of blood. Due to the delay of circulation, hormonal responses are generally slower than nervous response. Both systems involve diffusion (either diffusion out of blood and into tissue or diffusion across a synapse). However, the diffusion distances in synapses is considerably smaller in nervous communication so further increasing its speed over hormonal communication. The nervous system is not considered as specific as the endocrine system, with the nervous system supplying group of tissues or organs. For example, one motor neurone induces and effect of several muscle fibers. Organs such as skeletal muscle, smooth muscles and glands are targeted individually. Due to receptor sites on target cells, the endocrine system is able to be very specific is binding specifically to the appropriate cells. The nervous system is more associated with plasticity. Synaptic plasticity results in changes in the quantity of neurotransmitter released and how effectively the postsynaptic cells respond to the neurotransmitter. Although the effects of hormones are generally more permanent, the system is considered more elastic than plastic (changing but then returning to the original.) In conclusion, the body often combines the speed of the nervous system with the specificity of the endocrine system to create the neuroendocrine system. Neuroendocrine cells receive neurally transmitted information and release hormones in response which is carried via blood the the target cells. The neuroendocrine system is mainly organised by the hypothalamus.
Which system the nervous system or the endocrine system best suited to detect danger?
The nervous system
Which system the nervous system or the endocrine systemis best suited to detect danger?
The nervous system
How do you treat the nervous system disease?
Rehab is the best way to treat a nervous system disease. It is the way to free the body from tensions.
How do you treat nervous system disease?

What is the best drink for a weak nervous system?
diet soda
How does the nervous system coordinate the body's response to stimuli?
It looks across the entire world and sees their best friend and gets really happy
How can the representation of the nervous system best be demonstrated to students?
Machines that can interact with their surroundings. More recently, the human nervous system allows us not only to interpret sensory demonstrate the structure.
What is the best definition of the peripheral nervous system?
The peripheral nervous system consists of all the nerves outside of the brain and spinal cord. It connects the central nervous system to the rest of the body and controls voluntary movements as well as involuntary functions like digestion and heart rate.
The process by which neural impulses are transmitted through the nervous system is best described as?
The process by which neural impulses are transmitted through the nervous system is best described as electric impulses. Any damage to a nerve in the system will cause a breakdown in communication between nerve ending and the brain.
What is a nonliving example of a homeostatic system?
A thermostat controlling a heating/cooling system. The thermostat is set at a certain temperature. If the inside temperature drops below this setpoint, the heating system is signalled to raise it. If the inside temperature rises above the setpoint, the cooling system is signalled to lower it. Doing this maintains the temperature within a small band, keeping things relatively homeostatic. This is the best example I can think of.

Which sentence best describes integration in the nervous system?
Sensory receptors send signals to sensory neurons.
