Hello friends I am a neurologist, I am here today to help you understand the types of nervous systems and the reflex arc
The nervous system consists of two parts which are Peripheral Nervous System and Central Nervous System (In short PNS and CNS respectively)
The PNS is further broken down into two parts called the somatic and autonomic nervous systems
Fun fact, the autonomic nervous system also consists of two parts the Parasympathetic and the Sympathetic nervous systems
The CNS consists of the brain and the spinal cord and it delivers and receives messages from the neuron
The PNS consists of the nerves that branch off of the spinal cord and deliver and receive signals from the brain and the parts of the body
Now lets talk about the reflex arc, the reflex arc is the series of nerves that a signal passes through to get to the brain and the destination
1.First the sensory neuron receives the signal from the muscle
3. The motor neuron then takes the signal and transmits it lastly to the muscle
2. Then the signal goes to the control center or our CNS
Note that all the spaces are filled with relay neurons and their job is to transmit information form one to another
Thats it for today i hope you have learned something new
