What is the message sent down the neuron called?
What they relay is whether of not they were 'on' or 'off' and how often; and this occurs as an action potential firing frequency. There is no message in the sense that neurons might pass on complex messages, like an email for instance; or store memories of events and facts. No one neuron can do anything like that. It takes many neurons working together to achieve this.
What crosses a synapse?
Answer is Neurotrasmitters. There are several hundred types of neurotransmitters in brain. Some of them are Dopamine,Serotonin,acetylcholine,Adrenaline, Nor-adrenaline, Histamine,pep-tide neurotransmitters, certain amine acids. So impulse of depolarization flows across the nerve fiber and there is closed space between junction of two nerves, where chemical substances flows across, carrying the impulses to next nerve. After impulse is given to the next nerve fiber by say acetylcholine, then it will be destroyed by the enzyme acetylcholinesterase. Nor-adrenaline is taken up back by the nerve fiber.
What is an initial segment of a nerve impulse?
Axon hillock- a pyramidal shaped region where all axons originate fromInitial segment- an area just beyond the axon hillock where all the stimulatory and inhibitory signals coming into the neuron are algebraically summed and it is decided whether or not an action potential should propagate or not.-----The above describes the structure of the axon where the action potential is created.However, the actual nerve impulse (action potential) is generated in a series of steps based on how the ion channels trigger.In this respect the first segment of the nerve impulse is the stimulus, which has to trigger positive ion influx beyond a given threshold.After that stimulus exceeds the threshold, it triggers the opening of ion channels which pump sodium ions into the axon and potassium ions out, thus increasing the net positive charge on the inside of the neuron, depolarizing it and initiating the action potential (the nerve impulse).
Where do reflex actions occur?
Reflex action means a reaction you have given involuntarily. If you touch the immensely painful object, the touching hand or foot is removed away with out your knowledge. Here three neurons are involved. 1) Afferent 2) In the spinal cord 3) Efferent. This is called as reflex arc. Simultaneously information goes to higher centers and you notice the the problem, later on. So reflex action occurs at the level of spinal cord only.
How does the endocrine system and the nervous system maintain human health?
The endocrine system regulates various body functions through hormones, while the nervous system coordinates rapid responses to stimuli. Together, they maintain homeostasis by controlling processes such as metabolism, growth, stress response, and reproduction. These systems work in tandem to ensure proper functioning of organs and overall health.

Which is the last part of the neuron to be involved in the transmission of a neural impulse towards the next neuron?
Signalling ALONG a neuron is electrical, but signalling BETWEEN neurons is a chemical process. Neuron A 'passes' a message onto the next by releasing chemicals called neurotransmitters , which are then taken up by neuron B. The point at which these neurotransmitters are released from the neuron A is called the 'terminal bouton' and is the end of its axon. More specifically, it is the presynaptic membrane OF the terminal bouton at which the passing on of a message occurs.
Is impulse conserved in the given scenario?
In the scenario, impulse is conserved if the total impulse before an interaction is equal to the total impulse after the interaction.
What are neuro transmitters?
The nervous system is composed of many cells called neurons, these are essentially the functional units of the nervous system. ?Neurotrnasmitters are chemical messengers that are sent from one neuron to another neuron. ?So basically they are messangers communicating from one neuron to the next. ?Some neurotransmitters are excitatory which act to help activate a neuron, some neurotransmitters are inhibitory and act to reduce excitement of a neuron. ?Many many neurotransmitters will act on a neuron at a given time and the sum total will result in either an excitation or inhibition of that neuron. ?Examples of neurotransmitters include GABA, glutamate, serotonin, dopamine, acetylcholine, histamine, ?glycine, epinephrine, norepinephrine, melatonin, substance P, and many more!

How to find the magnitude of impulse in a given scenario?
To find the magnitude of impulse in a given scenario, you can multiply the force applied to an object by the time period over which the force is applied. This will give you the change in momentum of the object, which is equal to the impulse. The magnitude of impulse is a measure of how much the object's momentum changes due to the force applied to it.

What impulse occurs when an average force of N is exerted on a cart for S's?
The impulse is the product of the average force and the time period over which it is applied, as given by the formula: Impulse = Force x Time = N x s. This impulse results in a change in the cart's momentum, according to the principle of impulse-momentum theorem.
