like say this if you put your hand on top of a burning candle the heat will burn your hand and your nerve system will feel it and then it will send a signal up from your hand to your spinal cord and then the massage from your spinal cord will get sent up to your brain telling it what has happened and then the brain will send another massage down our spinal cord into your hand which will tell your muscle to lift up your arm away from the burning candle

What type of neurone carry electrical signal to the brain?
Afferent neurons (also called sensory neurons) carry signals to the central nervous system and the brain. Efferent neurons (also called motor neurons) carry signals from the brain.
A signal that the bladder is full is sent to the central nervous system by?
Sensory Neurons
Does the motor neuron send a signal to or from the muscle fiber?
Sensory Neuron sends info to the brain while the motor sends the info to the muscle fiber.The motor neurone sends a signal from the CNS or PNS to the effector muscle or gland. Therefore the motor neurone sends a signal TO the muscle fibre.
Numerous nerve impulses arriving at a synapse at the same time exert a cumulative effect?
Kind of. Each neurone can have thousands of inputs from other neurones arriving at the same time. It all depends on the types of signal arriving from the other neurones. There are 2 types of incoming signal; 1. Excitatory Post-synaptic potentials (EPSPs) - These inputs depolarise the neurone (bring the negative voltage of the neurone closer to 0mV). 2.Inhibitory Post-synaptic potentials (IPSPs) - These inputs hyperpolarise the cell (make the neurone voltage more negative). Some of the inputs coming to the neurone will be EPSPs, some IPSPs. If all the inputs come in and there are more EPSPs then the neurone will depolarise. If the neurone depolarises to the firing threshold (around -40mV) then an action potential will be propagated and the neurone will transmit the message to the next neurone in the chain. If the majority of the inputs are IPSPs then the neurone will hyperpolarise and will not fire. If there are more EPSPs than IPSPs but the neurone still doesn't depolarise enough to reach the firing threshold then the neurone will not fire.
What is the main function of a connecting neuron?
To take the signal from the sensory neurons to the motor neurons or other integrative neurons
How does the passage of a touch signal pass from skin to the cerebral cortex?
Pressure receptors in the skin pick up the stimulus. It passes along a sensory neurone to the central nervous system. Within the CNS it is transferred to the cerebral contex via an association neurone, relay neurone.
What are neurontransmitters?
a chemical that transmits a nervous systems signal across a synapse.
Which neuron will get a nerve impulse to an effector cell the fastest?
it transmits a signal through the the central nervous system ( CNS ) until it reaches a salivary gland (effector) :)
What is the name of a neuron that transmits a neural impulse from the central nervous system through the spinal cord to a muscle?
The neuron that transmits a signal from the nervous system to an effector is a motor neuron.
What type of neurone carry electrical signal to the brain?
Afferent neurons (also called sensory neurons) carry signals to the central nervous system and the brain. Efferent neurons (also called motor neurons) carry signals from the brain.
A signal conduction route to and from the central nervous system is a?
Reflex Arc
A signal that the bladder is full is sent to the central nervous system by?
Sensory Neurons
What is nervous coordination?
The nervous system recives stimuly from the external environment through the sense organs and transmit their information through the central nervous system. The central nervous system analysis it and than sends signal to the stimulate responses by the specific organs.
How can the hypothalamus receive signals from both the nervous and endocrine systems?
The hypothalamus connects the nervous system to the endocrine system, the hypothalamus receives the signal from the internal/external environments and then send chemical signals to the endocrine system to release the needed hormone for a particular function. So the hypothalamus does not receive signal from both, but transmits the signal to the endocrine system.
Does the motor neuron send a signal to or from the muscle fiber?
Sensory Neuron sends info to the brain while the motor sends the info to the muscle fiber.The motor neurone sends a signal from the CNS or PNS to the effector muscle or gland. Therefore the motor neurone sends a signal TO the muscle fibre.
What is the difference between the efferent and the efferent neurons?
they don't have a difference Unless you are talking about the direction of their signal. Afferent is taking information toward the central nervous system while efferent is taking information away from the central nervous system.
Is saying that a device transmits a signal correct?
Yes, it is correct
