The neuron that transmits a signal from the nervous system to an effector is a motor neuron.
These neurons are called motor neurons or somatic neurons. Somatic means pertains to the body.
motor neurons
motor neuron
it transmits a signal through the the central nervous system ( CNS ) until it reaches a salivary gland (effector) :)
Example: when you step on a nail, your body perceives a stimulus (change in external or internal environment) receptor is the specific thing identifying stimulus, in this case, the skin, then a nervous impulse is generated and is transmitted through a chain of neurons towards central nervous system, sent to the brain where the impulse is interpreted (integration) by the brain, brain will send off new impulse via motor neurons through spinal cord through nerve to muscle to carry out response.
Neural impulses (action potentials) are transmitted through axons which are covered in a myelin sheath for insulation.
The main difference is that motor neurons move signals away from the central nervous system and spinal cord where as sensory neurons move signals towards the central nervous system and spinal cord.
# Motor neurones have cell bodies inside the Central Nervous System (CNS) whilst in sensory neurones the cell body is located outside of the CNS # Motor neurones transmit impulses from the CNS to the effector which brings about a response to the situation, sensory neurones transmit impulses from to the CNS from the receptor. # Sensory neurones transmit impulses as a result of external stimuli such as pressure, light, temperature etc. Motor neurone transmit impulses passed along the CNS to the effector.
No, the autonomic nervous system does.
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.
Through the Central Nervous System
The synaptic gap, also called the synapse.
The stimulus is your bodies reaction to something, say you burnt your hand, this is the stimulus. The reaction is your bodies response to it. In this sense the stimulus will be sensed by sensory neurones which pass an electrical impulse through relay neurons until the impulse gets to the Central Nervous System. This then, gives out another impulse which travels down a Motor Neuron to the muscle telling your hand to be removed from the surface.....
sensory neurone --> enters spinal cord --> relay neurone --> brain(is not a reflex action) or motor neurone(if action is reflex)
