MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network. Different neurons have different jobs.

Detailed explanation-2: -The basic unit of the nervous system is a nerve cell, or neuron. The human brain contains about 100 billion neurons.

Detailed explanation-3: -The nervous system is mainly made up of cells called neurons. These are responsible for carrying messages to and from different parts of the body. Neurons are connected to each other, and to other cells, by synapses, which carry electrical signals, and neurotransmitters, which are the body’s chemical messengers.

Detailed explanation-4: -A type of cell that receives and sends messages from the body to the brain and back to the body. The messages are sent by a weak electrical current. Also called neuron.

Detailed explanation-5: -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.
