NERVOUS SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The nervous system uses both chemical and electrical ____ to send messages along nerves.
A
impulses
B
axon
C
synapse
D
dendrites
Explanation: 

Detailed explanation-1: -Neurons communicate via both electrical signals and chemical signals. The electrical signals are action potentials, which transmit the information from one of a neuron to the other; the chemical signals are neurotransmitters, which transmit the information from one neuron to the next.

Detailed explanation-2: -Summary. The nervous system uses electrical and chemical means to help all parts of the body to communicate with each other. The brain and spinal cord make up the central nervous system. Nerves everywhere else in the body are part of the peripheral nervous system.

Detailed explanation-3: -A nerve cell (neuron) communicates with other cells through electrical impulses when the nerve cell is stimulated. Within a neuron, the impulse moves to the tip of an axon and causes the release of neurotransmitters, chemicals that act as messengers.

Detailed explanation-4: -Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, such as pain.

Detailed explanation-5: -Answer: The nervous system uses electrical impulses to transmit messages. Neurons conduct electrical impulses by generating the action potential. Action potential is generated through the flow of positively charged ions across the neuronal membrane.
