Which type of neurone transmits a signal from a sense organ to the central nervous system?
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 structure transmits impulses from a receptor organ to an interneuron?
The structure that transmits impulses from a receptor organ to an interneuron is the sensory neuron. When a receptor organ detects a stimulus, it generates an electrical signal that travels along the sensory neuron's axon. This signal then reaches the synapse with the interneuron, facilitating the transmission of the impulse to the central nervous system for processing.
What connects a motor and a sensory neurone in the central nervous system and is involved in a reflex arc?
An interneuron connects a motor neuron and a sensory neuron in the central nervous system and plays a crucial role in a reflex arc. When a sensory neuron detects a stimulus, it sends a signal to the interneuron, which processes the information and relays the response to the motor neuron, triggering an appropriate reaction. This rapid communication allows for quick reflexive actions without the need for conscious thought.
Dendrites found on unipolar neurons are part of what?
Dendrites found on unipolar neurons are part of the sensory receptor that detects stimuli such as touch, pressure, vibration, and temperature. They transmit this sensory information to the neuron's cell body, which then processes and transmits the signal to the central nervous system.
What is the main function of a connecting neuron?
The main function of a connecting neuron, or interneuron, is to transmit signals between sensory neurons and motor neurons within the central nervous system. They help integrate and process information, allowing for complex neural functions such as thinking, decision making, and coordination of movements.
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.
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 structure transmits impulses from a receptor organ to an interneuron?
The structure that transmits impulses from a receptor organ to an interneuron is the sensory neuron. When a receptor organ detects a stimulus, it generates an electrical signal that travels along the sensory neuron's axon. This signal then reaches the synapse with the interneuron, facilitating the transmission of the impulse to the central nervous system for processing.
A signal conduction route to and from the central nervous system is a?
Reflex Arc
What term is used to describe the signal received by the central nervous system from the peripheral nervous system?
The term used to describe the signal received by the central nervous system from the peripheral nervous system is "afferent signals" or "afferent input." These signals carry sensory information from the body to the brain and spinal cord, allowing the central nervous system to process and respond to various stimuli.
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.
Dendrites found on unipolar neurons are part of what?
Dendrites found on unipolar neurons are part of the sensory receptor that detects stimuli such as touch, pressure, vibration, and temperature. They transmit this sensory information to the neuron's cell body, which then processes and transmits the signal to the central nervous system.

They help integrate and process information, allowing for complex neural functions such as thinking, decision making, and coordination of movements.
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.
