The Nervous System Flashcards
What are sensory receptors
They are a group of cells that detect a stimulus
What is the purpose of the myelin sheath
This speeds up the electrical impulse
What is the only neuron with dendrites
Sensory neuron
Where does the sensory neuron carry impulses from
Impulses are carried from the sensory receptors to the relay neurons
Where do the relay neurone carry the impulses from
Impulses enter relay neuron from the sensory neuron and are carried to the motor neurone
Where does the motor neurone carry impulses
Impulses are received from the relay neurone and are carried the effector cells
What is a effector cell
It is a muscle or gland
What is a synapse
This is a gap between two neurones
What is the chemical which transfers the nerve signal
Neurotransmitters
What is a reflex
This is an automatic, rapid response to a stimulus
