the somatic system control everything
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.
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.
The nervous system is faster than the endocrine system because nerve impulses travel through neurons at speeds up to 100 meters per second, while hormones released by the endocrine system must travel through the bloodstream to reach their target organs, which can take longer. Additionally, the nervous system reacts more quickly to immediate threats or stimuli, while the endocrine system is involved in regulating processes that require more sustained and long-term control.
Sensory neurons receive sensory input from the environment and transmit this information to the central nervous system, while motor neurons transmit signals from the central nervous system to the muscles and glands. Sensory neurons have a cell body located outside the central nervous system (in the dorsal root ganglia), while motor neurons have their cell bodies located within the central nervous system (in the spinal cord or brainstem). Sensory neurons are usually unipolar, with a single process extending from the cell body, while motor neurons are typically multipolar, with multiple processes extending from the cell body.
CNS = central nervous system (brain and spinal cord)PNS = peripheral nervous system (that part of the nervous system that extends outside the central nervous system)
Pain receptors, also known as nociceptors, detect tissue damage or potentially harmful stimuli, signaling pain responses. Somatic receptors, on the other hand, sense touch, pressure, vibration, temperature, and proprioception to help the body perceive its external environment and respond accordingly. Pain receptors specifically respond to noxious stimuli, while somatic receptors respond to various tactile sensations.
I don't belive you could just turn off your Nervous system. It is allways in action with everything you do.
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.
Messages are transmitted through the nervous system via electrical impulses. When a stimulus is received by a sensory receptor, it triggers an electrical signal that travels along the nerve cells, known as neurons. These signals are passed from neuron to neuron via chemical signals called neurotransmitters at junctions called synapses.
