Short-Answer Questions
​

Answer 1

Neurons (also called neurones or nerve cells) are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between. More than that, their interactions define who we are as people. Having said that, our roughly 100 billion neurons do interact closely with other cell types, broadly classified as glia (these may actually outnumber neurons, although it’s not really known).

Answer 2

Neuron are brain cells that convey or conduct nerve impulse from effector(muscles) to receptor (CNS) or from receptor (CNS) to effector(Muscles) through special chemical on their dendrites which is known as acetylcholine.
