order of reflex action

sensory receptors, sensory neurones, relay neurone, motor neuron, action

transmit signal from the receptor to the spinal cord

take the impulse from the relay neurone to move effector

an involuntary reflex that is there to protect you, the brain is not involved, its the spinal cord.

the junctions between 2 or more neurones . this is a very small gap.

Question	Answer
order of reflex action	sensory receptors, sensory neurones, relay neurone, motor neuron, action
sensory receptor….	detect stimili (sharp pain)
sensory neurone…	transmit signal from the receptor to the spinal cord
motor neurone ….	take the impulse from the relay neurone to move effector
what is an effector	muscle/gland
reflex arc….	an involuntary reflex that is there to protect you, the brain is not involved, its the spinal cord.
synapses	the junctions between 2 or more neurones . this is a very small gap.
