Is a forset fire a chemical reaction?
Fire is a chemical reaction. A forest fire is a disaster consisting of chemical reactions.
Is fire in a fireplace a physical or chemical property?
Fire is not a physical or chemical property. Fire is not a property. Fire is a chemical reaction where oxygen combines with some or all of the chemical components of the fuel, emitting light and heat.
Do the dendrites receive or release neurotransmitters?
You've sort of got it backwards: axon terminals initially release neurotransmitters into the synaptic cleft, from where they diffuse across the cleft and fit into receptor sites on ligand-gated sodium ion pores on the dendrites, causing those pores to open, allowing sodium ions into the dendrite, resulting in a change in the voltage of the dendrites membrane, which initiates the propagation of the signal along the dendrite and soma towards the axon hillock, where it may trigger an action potential in the axon.However, after the neurotransmitters have done their job at the dendrites, they can be "released" by the dendrites , as in let go of, to be re-absorbed, re-cycled, re-used by the axon terminals.The axons "give" the neurotransmitters to the dendrites as chemical messengers to convey the signal, and the dendrites "give them back" after the message has been received and conveyed onward.
What are functions of synaptic junction?
To "connect" two neurons, (or a neuron and a muscle cell), by providing a space between an axon terminal of one neuron and a dendrite of another neuron (or a muscle cell), so neurotransmitters that are released by an axon terminal can diffuse across that space to reach the dendrite (or muscle cell) and either initiate the possibility of the second neuron to fire or cause a muscle cell to contract.
What is the role of a dendrite in the neuron?
It receives impulses from other neurons, and then sends those nerve impulses to the body of the cell, where they are added together at the axon hillock, and if they provide a sufficient strength (voltage, potential), an action potential will fire in the output of the neuron, the axon.
What chemical is released into the gap?
neurotransmitter
What is the junction between the axon of one nerve cell and the dendrite of another nerve cell?
No, not at all. The axon is the transmitting end of a neuron, and a dendrite is the receiving beginning of another neuron.The axon sends its signal "through" a synapse between the axon terminal and a dendrite via chemicals called neurotransmitters that it releases into the synaptic space, which diffuse to and are taken into structures on dendrites called ligand-gated ion pores, which open to allow sodium ions into the dendrite, which change its electrical charge, which initiates the propagation of a corresponding signal along the dendrite and cell body toward the axon hillock, which, if enough signals from dendrites reach it, will then fire and send the nerve signal onward along the axon, as an action potential.
How is the structure of a neuron related to its functions?
The function of a neuron is to convey or process signals.The structure of a neuron allows these functions to occur.The relevant components of a neuron comprising its structure are:dendrites (inputs), soma(cell body), axon hillock (signal strength assessing trigger point), axon (output), axon terminal branches, and axon terminal buttons.Neurons receive signals, either from other neurons, or from receptor cells; they either simply convey the signal along the axon, or evaluate its strength and send it along the axon if the input is strong enough.The structure of the neuron allows this function to happen in the following way: the dendrites receive chemical messengers through a synapse from an axon terminal button, which opens pores in the dendrite which allow sodium ions in, creating an electric voltage; this voltage propagates down the dendrite and over the somato the axon hillock, where, if it is greater than a triggering value, it can cause the axon to fire an action potential along its length; when the action potential reaches an axon terminal button, it causes calcium ion pores to open in the button, which causes small bags of neurotransmitter chemicals to merge with the membrane of the terminal button, releasing the neurotransmitter chemicals into the synaptic cleft (gap), where they diffuse over to a dendrite.

Is Burning coal physical or chemical change?
Burning coal is a chemical change. Anytime heat is released (as such in fire) it will be a chemical property change.
What is energy of radiant objects such as fire?
Radiant energy is exothermic energy. Fire is a chemical reaction that produces heat. This heat is released as a result of the exothermic chemical reaction.
What is a type of fire is a chemical fire?
a fire with a chemical in it
When was Signal Fire Films created?

Do blood cells move from the axon terminal to the dendrites?
Technically a neural impulse moves from the cell body to the axon terminal, because a nerve impulse is defined as an electrical signal that travels along an AXON.This may be confusing because neural signals move in three places with respect to the neurons, in three correspondingly different ways, and only one is called the neural impulse.Neural signals move in these places: betweenneurons (ie, from one neuron to another), intoneurons, and along axons (the outputs of neurons, when a neuron has fired).BETWEEN NEURONS: A neural signal can be passed from one neuron to another, at a synapse, across the synaptic cleft, by the release of chemicals called neurotransmittersfrom the presynaptic neuron, which diffuse across the synaptic cleft, to fit into receptors on the postsynaptic neuron. This is a chemical transmission of the neural signal, not an impulse.INTO A NEURON: when a signal has passed from one neuron to another by the release, diffusion, and reception of neurotransmitters, it initiates a graded response in the dendrites of the postsynaptic neuron, which travels with decreasing strength down the dendrites and across the soma (cell body), until it reaches the root of the axon, the axon hillock. This graded response is also not an impulse.ALONG THE AXON: if enough graded response signalsreach the axon hillock at about the same time, (it might be helpful to think of them as degraded signals, since they get weaker the further they travel), such that their combined strengths can trigger an all or nothing action potential in the axon, then it can be said that the neuron has fired a neuronal impulse.So, there are neural signals which move betweenneurons and into neurons, and neural impulses which fire and move along axons from the cell body (soma).

Fire is a chemical reaction. A forest fire is a disaster consisting of chemical reactions.
Light and heat energy are being released from the fire where is the energy come from?
Energy is released from the chemical bonds in the substance that's burning.
