What else can I help you with?
Is the communication in the nervous system carried out by the neurons?
Yes, it's the nerve cells, also known as neurons, that communicate and do everything else that the nervous system does.
Which direction do messages pass down the nerve cells?
Nerve impulses are carried by neurons and passed to other neurons at junctions called synapses. cells pass messages The signal may be directly transferred or can be carried across the gap by chemicals called neurotransmitters.
Why are synapses necessary?
From what i know so far, synapses are important as they allow the message carried from neurotransmitters to slow down and then be carried across to different neurons in the body. I got that from my science book. I'm still wondering why slowing down the message is important. Or HOW its carried to different neurons, and I'm wondering why it needs to be slowed down in order to be transfered to another neurone.
What carries the nerve inpulse to the brain?
Nerve impulses are carried to the brain by specialized cells called neurons. These neurons transmit signals through electrochemical processes along their axons towards the brain where the information is processed and interpreted.
What carries the nerve impulse from the central nervous system to an effector?
Nerve impulses are carried from the central nervous system to the effector organs (muscles or glands) by motor neurons. These motor neurons form a pathway known as the efferent pathway.
Chemical communication is carried out between neurons by substances called?
neurotransmitters. These are chemical messengers that transmit signals across synapses, which are junctions between neurons. Neurotransmitters play a crucial role in regulating various physiological processes in the brain and body.
What part of nervous system worked when you are pricked by a needle?
This is a reflex that the peripheral nervous system was involved in. The prick was noted by sensory neurons which carried information into the spinal cord and synapsed with motor neurons which made you react, most likely by pulling away.
Why sensory neurons are called as afferent neurons?
Sensory neurons are called afferent neurons because they carry information from sensory receptors to the central nervous system. "Afferent" means to carry inward, referring to the direction of information flow towards the central nervous system.
What are the cables of the nervous system called?
Information from the peripheral nervous system is carried to the central nervous system by neural cables called nerves. The work groups that neurons cluster into are known as neural networks.
What neurons carry impulses from the brain or spinal cord to other organs and cause muscles to contract?
Impulses from the brain go mostly through the channels in the spinal cord and control most everything that goes on in the body. It is a two way street with information generated chemicals being carried throughout the body.The brain uses neurons to decide what information is acted upon.
When you stub your toe the pain message is carried to your brain by the?
central nervous system....................Apex
What are neurons called that detect stimuli in the skin and eye?
sensory neurons
