In monosynaptic reflex,do we consider synapse between neuron-neuron only??
I have read somewhere that this reflex consist of 2 neurons only???No if we count number of synapses,1 is between neuron-neuron,other is between sensory neuron and receptor and third is between motor and effector? So how we say it is 1 i-e synapse????
The number of synapses can vary from just a few, which is required for the withdrawal reflex, to several, which is required for the escape reflex. A reflex is a response to a stimuli that bypasses the normal processing that takes place in the central nervous system, meaning the spinal cord and the brain. It is a response designed for quick and immediate action, to preserve the health of the organism involved. As mentioned earlier, depending on the body part involved, it may be just a few neuron-to-neuron synapse connections, such as touching a hot stove eye and pulling back immediately. Or it may be a "bucket brigade" where there are many synapses coordinating an overall body system acceleration, which is what happens in the "fight or flight" syndrome, set off when the adrenal glands pump epinephrine into the blood stream.
