In these days of the internet, the flow of information is often described in terms of traffic. Traffic analogies are also common in the study of neuroscience, where information flow is bidirectional as in a two lane highway. This means that information travels both from the nervous system to the rest of the body as well as from the body to the nervous system.
-----
In the case of the central nervous system, the two-lane highway can best describe the directionality of the efferent nerves (sending signals from the brain to the body, particularly for motor control) and afferent nerves (sending signals from the body to the brain, particularly for sensory input).
So, yes, in this respect, it can be likened to a two-lane highway.
No, not all living organisms have a nervous system. Invertebrates like sponges, jellyfish, and corals lack a nervous system, while all vertebrates, including humans, have a nervous system.
The outer nervous system consists of the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and receives sensory information. The autonomic nervous system regulates involuntary functions like heart rate, digestion, and breathing.
The two types of peripheral nervous system are the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary bodily functions like heart rate and digestion.
The 3 subsystems of the Nervous System are the Central Nervous System (CNS), which includes the brain and spinal cord, the Peripheral Nervous System (PNS), which includes nerves outside the CNS, and the Autonomic Nervous System (ANS), which regulates involuntary functions like heart rate and digestion.
The somatic nervous system controls voluntary movements, like dancing. This system includes the nerves that connect the central nervous system to the muscles involved in dancing.
it sends messages to the brain for the nervous system it is like the information highway of the nervous system
It ac ks like a highway for the nervous system ( OK not nervous, I'm not) It helps to transport reactions too.
the peripheral nervous system
Bandwidth is a way of measuring how much data can travel along a certain path in a network. It is much like a highway or road; an 8 lane highway can handle twice as much 'traffic' (or page views) as a 4 lane highway.
On a freeway/highway, the lane which contains the diamond like shape is a separate travel lane. Specifically this lane is dedicated to the "ride share" and/or individuals carpooling.
No, not all living organisms have a nervous system. Invertebrates like sponges, jellyfish, and corals lack a nervous system, while all vertebrates, including humans, have a nervous system.
The central nervous system is like the command center, while the peripheral nervous system is like the communication center between the organs of the body and the CNS and visa versa.
The outer nervous system consists of the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and receives sensory information. The autonomic nervous system regulates involuntary functions like heart rate, digestion, and breathing.
The two types of peripheral nervous system are the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary bodily functions like heart rate and digestion.
PNS means peripheral nervous system. It has two main components: the autonomic nervous system and the somatic, or voluntary nervous system. The autonomic nervous system also contains two parts: the sympathetic nervous system and the parasympathetic nervous system.
The easiest way to define the peripheral nervous system is to first define the central nevous system. the central nervous system consists of the brain and spinal cord. the peripheral nervous system is everything else. The peripheral nervous system (or PNS) is divided into the autonomic (involuntary like smooth muscle peristalsis in the gut) and somatic (voluntary, like flexing your arm to show off your muscles) nervous systems. The autonomic nervous system is again further subdivided into the parasympathetic nervous system (rest and digest) and the sympathetic nervous system (fight or flight).
