Q

what does the somatic nervous system

Q

sensory neuron =

A

these neurons tell the rest of the brain about external and internal environment by processing information taken from one of the 5 senses. carry messages from PNS to CNS.

Q

what is electric transmission

A

when a neuron is activated by a stimulus the inside of the cell becomes positively charged for a split second causing action potential to occur, creates electrical impulse which travels down the axon
