Definition of nervous system in English English dictionary
An organ system that coordinates the activities of muscles, monitors organs, constructs and processes data received from the senses, and initiates actions
the entire integrated system of nerve tissue in the body: the brain, brain stem, spinal cord, nerves and ganglia
Includes all of the neural structures in the body: the central nervous system consists of the brain, spinal cord, and optic nerves; the peripheral nervous system consists of the nerve roots, nerve plexi, and nerves throughout the body
the part of the body that carries messages to the brain The nervous system consists of the brain, neural paths, and nerve endings
The telephone communication center of the body All information from outside the body and from inside the body must pass through this system The two parts of the nervous system include the Central and Peripheral Nervous systems
The nervous system is the body tissue that records and distributes information in the body using electrical and chemical transmission It has two parts The "central" nervous system is comprised of the brain and spinal cord The "peripheral" nervous system is the nerve tissue that transmits sensation and motor information back and forth from the body to the central nervous system
The nervous system is the vast network of cells specialized to carry information (in the form of nerve impulses) to and from all parts of the body in order to bring about bodily activity In vertebrates, the brain and spinal cord together form the central nervous system; the remaining nervous tissue is known as the peripheral nervous system and includes the autonomic nervous system, which is itself divided into the sympathetic and parasympathetic nervous systems The basic functional unit of the nervous system is the neuron (nerve cell)
A system in the body that is comprised of the brain, spinal cord, nerves, ganglia and parts of the receptor organs that receive and interpret stimuli and transmit impulses to effector organs
network of cells that transmit nerve impulses throughout the body (to the brain, muscles, and organs)
Any of the following, alone or in combination: lymphocytic meningitis; cranial neuritis, particularly facial palsy (may be bilateral); radiculoneuropathy; or, rarely, encephalomyelitis Encephalomyelitis must be confirmed by demonstration of antibody production against B burgdorferi in the CSF, evidenced by a higher titer of antibody in CSF than in serum Headache, fatigue, paresthesia, or mildly stiff neck alone are not criteria for neurologic involvement
the system of nerves including the brain, the cranial nerves, the spinal cord, the spinal nerves, and the peripheral nerves; includes the autonomic(sympathetic and parasympathetic) nerves
Typically an electrochemical network in a system that is assembled as an extension of sensory bundles The nervous system extends to a size and complexity as is required to spectrally "interpret" perceptics The nervous system can be considered as having filtering characteristics that break down complex vibration into separate individual "notes " These are "weighted" as to relative importance Templates store necessary relationships Nerve firings are noted for "Change in Characteristics" to determine if a sense is being stimulated or sedated Inhibitors and Accelerators can be noted in a frequency domain understanding thereby showing function clearly
Your nervous system consists of all the nerves in your body together with your brain and spinal cord. The system of cells, tissues, and organs that regulates the body's responses to internal and external stimuli. In vertebrates it consists of the brain, spinal cord, nerves, ganglia, and parts of the receptor and effector organs. your nerves, brain, and spinal cord, with which your body feels pain, heat etc and your movements are controlled. System of specialized cells (neurons, or nerve cells) that conduct stimuli from a sensory receptor through a neuron network to the site (e.g., a gland or muscle) where the response occurs. In humans, it consists of the central and peripheral nervous systems, the former consisting of the brain and spinal cord and the latter of the nerves, which carry impulses to and from the central nervous system. The cranial nerves handle head and neck sensory and motor activities, except the vagus nerve, which conducts signals to visceral organs. Each spinal nerve is attached to the spinal cord by a sensory and a motor root. These exit between the vertebrae and merge to form a large mixed nerve, which branches to supply a defined area of the body. Disorders include amyotrophic lateral sclerosis, chorea, epilepsy, myasthenia gravis, neural tube defect, parkinsonism, and poliomyelitis. Effects of disorders range from transient tics and minor personality changes to major personality disruptions, seizures, paralysis, and death
The system of cells, tissues and organs that regulates the body's responses to internal and external stimuli In vertebrae it consists of the brain, spinal cord, nerves, ganglia and parts of the receptor and effector organs
A regulatory system of the body that consists of neurons and neuroglial cells The nervous system is divided into two parts, the central nervous system (CNS) and the peripheral nervous system (PNS)
The collection of body tissues that record and distribute information by electrical and chemical signals It includes the central (brain and spinal cord) and peripheral nervous systems
The system of the body responsible for the transmission of information from the brain to the rest of the body and from the rest of the body to the brain; it is composed of the central nervous system (the brain and the spinal cord) and the peripheral nervous system (which consists of the remainder of the nerves in the body)
The nervous system involves the brain, spinal cord, and all of the peripheral nerves that branch off from the spinal cord
Say: ner-vuss Let's give a round of applause to your nervous system! This system is made up of your brain and all the nerves connecting to it Together, they act like a super-fast, two-way message highway that helps you tell your body what to do and even move, think, and feel For example, when you touch something really hot, your nervous system sends a message from your fingers to your brain, saying, "You're touching something really hot!" Then another message comes from your brain back to your fingers, telling them to "Pull back!" All of this communicating happens in a split second, saving you from burning your fingers badly Your nervous system also lets you feel the soft fur of a puppy, button your shirt, and taste yummy foods It lets you run and kick a soccer ball and feel good after you score the winning goal! Think of the millions of jobs that the nervous system does for you!
~ The collection of nerves and throughout the body, each sending signals to the brain such as pain, heat, cold, etc
In humans and other vertebrates, the part of the nervous system that regulates the involuntary activity of the heart, intestines and glands. These activities include digestion, respiration, perspiration, metabolism, and the modulation of blood pressure
The part of the peripheral nervous system that transmits signals from central nervous system to skeletal muscles, and from receptors of external stimuli thereby mediating sight, hearing and touch
The part of the vertebrate nervous system that regulates involuntary action, as of the intestines, heart, and glands, and that is divided into the sympathetic nervous system and the parasympathetic nervous system. Part of the nervous system that is not under conscious control and that regulates the internal organs. It includes the sympathetic, parasympathetic, and enteric nervous systems. The first, which connects the internal organs to the brain via spinal nerves, responds to stress by increasing heart rate and blood flow to the muscles and decreasing blood flow to the skin. The second comprises the cranial nerves and the lower spinal nerves, which increase digestive secretions and slow the heartbeat. Both have sensory fibres that send feedback on the condition of internal organs to the central nervous system, information that helps maintain homeostasis. The third division, embedded in the walls of the stomach and intestines, controls digestive movement and secretions
Your central nervous system is the part of your nervous system that consists of the brain and spinal cord. The portion of the vertebrate nervous system consisting of the brain and spinal cord. the main part of your nervous system, consisting of your brain and your spinal cord
originates in the brain stem and lower part of the spinal cord; opposes physiological effects of the sympathetic nervous system: stimulates digestive secretions; slows the heart; constricts the pupils; dilates blood vessels
The part of the autonomic nervous system originating in the brain stem and the lower part of the spinal cord that, in general, inhibits or opposes the physiological effects of the sympathetic nervous system, as in tending to stimulate digestive secretions, slow the heart, constrict the pupils, and dilate blood vessels
The part of the vertebrate nervous system constituting the nerves outside the central nervous system and including the cranial nerves, spinal nerves, and sympathetic and parasympathetic nervous systems
One of the two divisions of the autonomic nervous system ( the other being the parasympathetic nervous system), consisting of fibers that leave the central nervous system, pass through a chain of ganglia near the spinal cord, and are distributed to heart, lungs, intestine, blood vessels, and sweat glands In general, sympathetic nerves dilate the pupils, constrict peripheral blood vessels, and increase heart rate
originates in the thoracic regions of the spinal cord; opposes physiological effects of the parasympathetic: reduces digestive secretions; speeds the heart; contracts blood vessels
One of two divisions of the autonomic nervous system that controls many of the involuntary activities of the glands, organs, and other parts of the body
This part of the nervous system regulates involuntary reactions to stress such as increased heart and breathing rates, and other physiological reactions Ever felt an 'adrenalin rush?' That was your sympathetic nervous system at its finest Many asthma drugs, such as albuterol, mimic this system in attempting to relieve an asthma flare
part of the nervous system that operates automatically without conscious choice (such as nerves responsible for blood circulation, digestion, breathing, etc.)
The part of the autonomic nervous system originating in the thoracic and lumbar regions of the spinal cord that in general inhibits or opposes the physiological effects of the parasympathetic nervous system, as in tending to reduce digestive secretions, speeding up the heart, and contracting blood vessels
