How does your nervous system send signals to other body systems?
The basic signal in the nervous system is called an action potential. It is a rapid change in the surface charge of the cell membrane from a value around -70mV to 30 mV over several milliseconds controlled by the selective flow of sodium Na+, calcium Ca++ and potassium K+ ions (mostly).
Which is the space that separates two neurons?
Synapses
What is affector neurons?
these have one or more receptors that detect change in either the external or internal environment, information that is detected is transmitted as an electrical impulse to the CNS by the affector neuron.
What is an environmental change that stimulates sensory neurons?
Sensation
Which sequence best describes the change in signals as sensory neurons in the eye respond to an external stimulus?
The sequence typically involves the conversion of external stimulus (light) into electrical signals by photoreceptor cells in the retina. These signals then pass through the optic nerve to the brain, where they are processed and interpreted, resulting in the perception of visual information.
What energy change happens in your eyes?
The energy changes into an electrical sign called impulses at the back of your eyeball called the retina.
How your brain and sensory organs get information from the outside world?
Your brain has about 100 billion neurons, all of which are interneurons. Each of these neurons may receive up to 10,000 messages from other neurons and may send messages to about 1,000 more. Every day, billions of nerve impulses travel through your nervous system from neuron to other neurons or body structures. The place where a neuron transfers an impulse to another structure is called a synapse. At the axon tips, electrical signals carried through the neuron change into a chemical form. This change allows the message to cross the gap. The message then continues in electrical from through the next neuron.
How do sound energy chage to eletrical energy?
To change sound energy into electrical energy you need to use a transducer, which changes sound into electrical impulses.
Electrical change in the neuronal membrane that is transmitted along axon is?
Action potential is the term for an electrical change in the neuronal membrane transmitted along an axon. The axon is part of a nerve cell that conducts impulses.
How electrical activity of neurons might be measured?
The information each neuron processes determines how strong the action potential (electrical current) is within each neuron. An example of studying the electrical activity is by using temperature. The neurons which detect the temperature change are called sensory neurons. If you stimulate the neurons by leaving your fingertip in cold water for an adequate amount of time the electrical current within each neuron is increased as the temperature of your fingertip drops. The neurons within the fingertip sense the temperature drop and emit the electrical current, then the next neuron senses the temperature drop as the fingertip is held in the cold water and emits a stronger electrical current, the colder temperature in the next neuron as your finger is held in the water emits an even higher frequency and so on until the message arrives at the spinal cord and is then sent to the brain through the now very strong electrical current within the neurons informing it of the temperature decrease and then resulting in action outcome.
How does multiple sclerosis affect human health?
To create movement and simple bodly functions the neurons in our bodies need to relay messages to one another by electrical impulses. When someone has ms the body begins to destroy what is called myelin sheaths and the cells that produce myelin. The sheaths are then replaced by hard tissue which don't allow the electrical impulses to pass throu. Which can cause mild to sever muscle weakness abnormal sensations such as numbness or tingling over any part of the body, vision change, loss of coordination, tremors, paralysis, poor posture and bowel and bladder dysfunction. All depending on how sever the case is.
When a change in the environment that initiates the transmission of an electrochemical charge along a neuron is known as?
A momentary change in electrical potential on the surface of a cell, especially of a nerve or muscle cell, that occurs when it is stimulated, resulting in the transmission of an electrical impulse. &/or "nerve impulses" or "spikes".

What is the instrument called that can change electrical voltage?
Electrical voltage can be changed by a transformer.
What is affector neurons?
these have one or more receptors that detect change in either the external or internal environment, information that is detected is transmitted as an electrical impulse to the CNS by the affector neuron.
How do nerve impulses travel along neurons?
Point to point or saltatory conduction.
