Although nerve impulses are electrical signals that travel along nerves in the same way, the specific response can differ based on the type of nerve fiber involved, where the impulse is being sent, and the neurotransmitters released. Different nerve fibers may lead to different responses in the body due to variations in the pathways and connections in the nervous system. Additionally, the specific receptors and effector organs that the nerve impulses target can also influence the response.
What else can I help you with?
Can there be smaller or larger nerve impulses?
Nothing stays the same, right? The answer is, of course.
When nerve impulses from several presynaptic neurons stimulate a single postsynaptic neuron at the same time it is called?
chemical synapse
When impulses from various sources have an additive effect on a neuron the process is called?
When impulses from various sources have an additive effect on a neuron, the process is called summation. This can occur through temporal summation, where multiple impulses from the same source rapidly fire in succession, or spatial summation, where impulses from different sources converge at the same time to reach the neuron's threshold for firing.
Is fiber same as axon?
No, fiber refers to any thread-like structure in the body, while axon specifically refers to the long extension of a nerve cell that conducts electrical impulses. Axons are a type of fiber found in the nervous system.
Why don't all plant cells look the same?
By definition, all human cells are animal cells. Different cells look different from others, no matter the organism. A human nerve looks almost identical to a nerve from a chimp, but a human nerve looks nothing like a cell from a chimp's muscles.
Can there be smaller or larger nerve impulses?
Nothing stays the same, right? The answer is, of course.
What is a difference between optic nerve and auditory nerve?
Optic nerve is found in the eye which sends the nerve impulses from the eye to the brain. The auditory nerve is present in the ear and sends the nerve impulses from the ear to the brain. They both have the same functions though they're present in different places.
Are neurons and nerve cells different name for the same thing?
True
When nerve impulses from several presynaptic neurons stimulate a single postsynaptic neuron at the same time it is called?
chemical synapse
How are diaphragm and intercostal muscles stimulated?
The diaphragm is stimulated the same way all other muscles are - nerve impulses that originate in the brain (or sometimes the spinal cord). The intercostal muscles expand during inhalation and contract during exhalation in response to the movement of the lungs by the diaphragm.
Can a nerve fibre and nerve both carry sensory and motor impulses?
There are the Mixed Nerves in the spinal column that carry both sensory and motor nerves, but these neurons have 2 different jobs that they do,& I know of no neurons doing both as the impulses travel to 2 different locations which couldn't be done at the same time.
What does neuron d0?
A neuron is a single unit of nerve fiber. Most neurons jobs are to allow chemical and electrical impulses to pass from one part of the body to the other. Neurons in the brain function the same way, sending impulses back and forth.
What is the primary role of muscle spindles?
the striated portions of the intrafusal fiber contract to keep the spindle taut at different muscle lengths. If the whole muscle is stretched, the muscle spindle is also stretched, triggering sensory nerve impulses on its nerve fiber. These sensory fibers synapse in the spinal chord with lower motor neurons leading back to the same muscle. Impulses triggered by stretch of the muscle spindle contract the skeletal muscle.
Which of the following types of neurons carries impulses away from the CNS?
They are called as motor neurons. They are same like sensory neurons. Only difference the direction of the nerve impulse. The nerve impulse travel from dendrites to body to axon to axon terminals.
When impulses from various sources have an additive effect on a neuron the process is called?
When impulses from various sources have an additive effect on a neuron, the process is called summation. This can occur through temporal summation, where multiple impulses from the same source rapidly fire in succession, or spatial summation, where impulses from different sources converge at the same time to reach the neuron's threshold for firing.
What are the two important principles related to nerve impulses?
1. The All-or-None Law states that the impulse is independent of the properties of the stimulus which started it. As long as the nerve cell is stimulated by an impulse of a certain minimal strength, it makes no difference how strong the exciting impulse is - just as a match or a blowtorch produces the same reaction in a fuse. It either fires or does not and there are no shades in between. The nerve impulse remains at the same strength as it travels along the nerve fiber, just as the spark remains at the same intensity as it moves along the fuse. The reason for this is evident in what has been said about a stimulus releasing energy in the fiber. It does not contribute energy.Impulse size and speed: The nerve impulse varies with the size of the fiber. (It is proportional to the square of the fiber's diameter.The size of the nerve impulse also depends on the condition of the fiber - being altered if drugged, deprived of oxygen, fatigued or in an abnormal state.2. The Frequency Principle states that there are more impulses per second with the stronger stimulus than with the weaker stimulus. A stronger stimulus produces impulses more frequently than the weaker stimulus. The frequency of nerve impulses is thus a function of the intensity of the stimulus.
Are Aleve and naproxen the same thing?
No, Aleve is a NSAID (non steroidal anti inflammatory), while flexeril is a muscle relaxant that blocks nerve impulses that are being sent to the brain.
