The function of the nervous system is to enable us to feel our surroundings. The five senses (sight, touch, hearing, taste and smell) have different sensory neurones in various parts of the body. The most sensitive parts of the body are the fingertips and lips, which have far more sensory neurones per square centimetre than other parts of the body. The nerve impulse travels from the sensory neurone, across a synapse (the gap between the end of one neurone and the dendrites (fingers) of the next) and reaches the next neurone. The signal reaches the coordinator (either the brain or spinal cord) and is then sent to a certain part of the body via a motor neurone, which eventually reaches the muscle and causes a movement. The nervous system is effected by stimulants and depressants, such as alcohol and drugs, which change the speed of reaction times. Parts_and_function_of_nervous_system

What are three main functions of the nervous system give an example of each?

What are the two parts of nervous system identify each part?
central nervous system (brain an spinal cord) peripheral nervous system (anything else)
What the nervous system is?
The nervous system consists of the brain which brings throughout your body Theirs two parts of the nervous system, the cetral nervous system, and the peripheral nervous system. The central nervous system contains the brain, spinal cord, and retina. The peripheral nervous system consists of sensory neurons, clusters of neurons called ganglia, and nerves connecting them to each other and to the central nervous system.
What system controls an animal's organ system-circulatory system-excretory system-and nervous system?
We can say all the systems controls each other but the whole body is controlled by Nervous system and Endocrine System. The Endocrine System by hormones controls the excretory system and controls the nervous system during emergency by releasing Adrenaline hormone. So all organ systems controls each other.
A large concentration of cells bodies within the central nervous system is referred to as?
A large concentration of cell bodies within the central nervous system is referred to as a nucleus. Each nucleus typically carries out specific functions related to processing and transmitting information within the nervous system.
What is a Central Nervous System?
The nervous system helps all the parts of the body to communicate with each other. The brain and spinal cord make up the central nervous system. The other nerves of the body are called the peripheral nervous system. Problems of the nervous system include epilepsy, meningitis, multiple sclerosis (MS) and Parkinson's disease.
What is the functions of the autonomic nervous system?
The involuntary nervous system that is involved with organ regulation is called the Autonomic nervous system (ANS) and is comprised of the Sympathetic nervous system and the Parasympathetic nervous system.
How is the human organism made up?
The human organism is composed of various organ systems that work together to maintain life functions. These systems include the circulatory system, respiratory system, nervous system, digestive system, and many more. Each system carries out specific functions necessary for the overall health and survival of the individual.
How do the nervous and respiratory system relate to each other?
Nervous system controls respiratory system .
The autonomic nervous system includes which of these major components?
The Sympathetic and Parasympathetic nervous systems are the divisions of the ANS. The sympathetic is where "fight or flight" comes in, and the parasympathetic is what calms us down afterward -- they work to balance each other.
What are the differences between the central nervous system and the autonomic nervous system?
The central nervous system is the part of the nervous system that integrates the information that it receives from, and coordinates the activity of, all parts of the bodies of bilaterian animals and the endocrine system is a system of glands, each of which secretes a type of hormone directly into the bloodstream to regulate the body.
