Part I

Note: Parts II and III follow below, complete all three.

Write a 350- to 700-word response to the following: Explain the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior.

The communication process of neurons in the brain A brain of an average human contains approximately 100 billion nerve cells or best known as neurons. Neurons perform as information transmitters and receivers to other neurons or to muscles in the body. Neurons have these tiny fibers that extend from the body of the cell and its main function is to receive incoming messages and transmit them to the main cell. Outgoing messages to other neurons and muscles or glands are carried out by a single long fiber called the axon. Axons are covered with a white fatty tissue called myelin sheath. The myelin sheath provides insulation to avoid signals from other neurons to interfere with each other and it also increases speed when signals are been transmitted. Motor neurons carry messages from the spinal cord or the brain to the muscles and glands. Al l neurons in the nervous system only speak one language ON or OFF electrochemical impulses. The communication process of neurons in the work by impulses or what it’s also called firing. When a neuron receives a message from other neurons it automatically excites the neuron or tells the neuron to fire. This term is also known as electrochemical impulse or discharge. After the neuron has fired, it returns to a resting state and remains ready to fire again. During resting state more positive charge ions remain on the outside of the neuron and negative charged ions remain on the inside. During the action or excitement phase, Ion exchange process begins by positively charge Ions are mixed with negatively
