The autonomic nervous system (ANS) regulates involuntary bodily functions, such as heart rate, digestion, and respiratory rate. It comprises two main branches: the sympathetic nervous system, which prepares the body for "fight or flight" responses during stress, and the parasympathetic nervous system, which promotes "rest and digest" functions that conserve energy. The ANS operates largely unconsciously, helping maintain homeostasis and responding to changes in the internal and external environment. It plays a crucial role in managing bodily responses to stress, relaxation, and overall health.
What else can I help you with?
What does the voluntary nervous system control?
the somatic system control everything
Why we don't forget to take breath?
because it comes automaticBreathing is partially controlled by the voluntarynervous system and partially controlled by the autonomicnervous system. While the voluntary nervous system can hold your breath for a period of time (I have been able to do a bit over 3 minutes), the autonomic nervous system eventually kicks in and forces you to breath. When you aren't thinking about breathing, the autonomic nervous system automatically keeps you breathing at a fixed rate needed to keep blood oxygen levels adequate for your current level of exertion. This is an automatic feedback system.
Skeletal muscles are voluntary muscles that are under the control of what?
movement of bones--example, when you walk, muscles are pulling your bones so you can take steps.
What neurons make up the peripheral nervous system?
Unified network of communications, but on an anatomical basis, it is divided into two primary portions. Which peripheral nervous system is the second portion.The spinal cordThe peripheral nervous system consists of autonomic and the somatic nervous systems.
What are two major divisions of the nervous system?
THE TWO DIVISION OF THE NERVOUS SYSTEM ARE THE CENTRAL NERVOUS SYSTEM OR CNS AND PERIPHERAL NERVOUS SYSTEM OR PNS . Central nervous system consist of the brain and the spinal cord . It receives and sorts out information coming from the environment and from inside the body and determines the appropriate action. Peripheral nervous system is made up of nerves that extend throughout the body . It is through these nerve cells that communicate between the Central nervous system and body tissues take place
How do you take care of the senses and the nervous system?
You can take care of the senses and the nervous system by eating foods that are high in B vitamins. These are known to support the nervous system and senses.
Does the decision-making function of the nervous system take place in the CNS?
Yes. The CNS is in the brain and spinal cord.
What part of nervous system carry all spinal nerves?
The nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let's take a look at the peripheral nervous system.Peripheral Nervous SystemThere are two types of cells in the peripheral nervous system. These cells carry information to (sensory nervous cells) and from (motor nervous cells) the central nervous system (CNS). Cells of the sensory nervous system send information to the CNS from internal organs or from external stimuli. Motor nervous system cells carry information from the CNS to organs, muscles, and glands. The motor nervous system is divided into the somatic nervous system and the autonomic nervous system. The somatic nervous system controls skeletal muscle as well as external sensory organs such as the skin. This system is said to be voluntary because the responses can be controlled consciously. Reflex reactions of skeletal muscle however are an exception. These are involuntary reactions to external stimuli.The autonomic nervous system controls involuntary muscles, such as smooth and cardiac muscle. This system is also called the involuntary nervous system. The autonomic nervous system can further be divided into the parasympathetic and sympathetic divisions.The parasympathetic division controls various functions which include inhibiting heart rate, constricting pupils, and contracting the bladder. The nerves of the sympathetic division often have an opposite effect when they are located within the same organs as parasympathetic nerves. Nerves of the sympathetic division speed up heart rate, dilate pupils, and relax the bladder. The sympathetic system is also involved in the flight or fight response. This is a response to potential danger that results in accelerated heart rate and an increase in metabolic rate.Thats all I know about a nervous system and spinal nerves hope it is helpful.
How does the heart help the nervous system?
although the heartbeat is not controlled by the nervous system,the autonomic nervous system does influence the heart rate.
What are two major divisions of the major system?
THE TWO DIVISION OF THE NERVOUS SYSTEM ARE THE CENTRAL NERVOUS SYSTEM OR CNS AND PERIPHERAL NERVOUS SYSTEM OR PNS . Central nervous system consist of the brain and the spinal cord . It receives and sorts out information coming from the environment and from inside the body and determines the appropriate action. Peripheral nervous system is made up of nerves that extend throughout the body . It is through these nerve cells that communicate between the Central nervous system and body tissues take place
What the activities that control the digestive system?
The purpose of the digestive system is to break down food to make it absorbable into the bloodstream.
Does diffusion or osmosis take place in the nervous system?
Diffusion is the process of cell transfer within the nervous system. It is diffusion of the ions that allows for transport and solubility to complete the process. Osmosis is used in other cellular areas.
