NNNELA

Chapter 2 covers the nervous system, neurons, and their interrelation, emphasizing the role of neuroscience in understanding behavior and psychological processes. It details the structure of neurons, including dendrites, soma, axon, myelin sheath, and axon terminals, which are essential for transmitting messages. The chapter also explains action potentials as electrical charges that travel along neurons and the processes of reuptake and enzymes in synaptic communication.

SUMMARY OF CHAPTER 2

NEURONS AND NERVES: BUILDING THE NETWORK


This chapter discussed what are the nervous system, neurons, and nerves and how they related to one another. This explores
the complex systems of the cells, chemicals and will work together to produce a behaviour, thoughts, and actions. First part of this
arrangement is the nervous system; nervous is a network of the cells that carries information to all parts of the body and from all
parts of the body. Neuroscience is a branch of the life science that deals with the structure and functioning of the brain, neurons, and
nerves tissue that will form a nervous system. Neuroscience have branch called biological psychology or behavioural neuroscience
that focuses on the biological bases of psychological processes, behaviour, and learning.

STRUCTURE OF NUERON: THE NERVOUS SYSTEM’S BUILDING BLOCK


Neuron is the specialized cell in the nervous system that receives and sends message within that system. Neuron has five
part called Dendrites, Soma, Axon, Myelin sheath, and Axon terminal. Dendrites means “tree-like” or “branch” are parts of neuron that
receive a message from other cells. Dendrites are attached to soma or the “cell body” that contains the nucleus and keeps entire cell
alive and functioning. Axon (from the Greek word “axis”) is the fiber attached to Soma that Carry a messages out to cells. Myelin
sheath is the Protective Coating of fat and protein that wraps around the axon like links of sausage. The end of axon is the Axon
terminals that responsible for communicating with other nerve cells.

THE NEURAL IMPULSE ACTION POTENTIAL


Action potential also called a nerve impulse is an Electrical charge that travel along the membrane of a neuron. The neuron at
rest the resting potential have negatively charge inside and a positively charged outside. The neutral impulse is the action potential
occurs when positive sodium ions enter into the cells. The neutral impulse continues as the action potential moves down the axon
toward axon terminals the cell areas behind the action potential return to their resting state.
