NURS 6630: Psychopharmacologic Approaches to Treatment of Psychopathology Week 1: Assignment 

1. The neuron consists of three important parts, the cell body (also called soma) and two extensions called axons, and dendrites. The core part of the neuron is the cell body, with its responsibility to maintain the cell and allow it to function efficiently (Guy-Evans, 2021) The cell body has tree-like projections called dendrites, which provides electrical impulse from other neurons and transmitting electrical signals to the cell body (Guy-Evans, 2021). The axon is a structure which carries an electrical impulse away from the cell body to its axon terminal and to another neuron. Electrical impulses are initiated when an impulse is generated via a stimulus that depolarizes a cell membrane, disrupting the balance of the electrolytes sodium and potassium in the cell, generating a temporary shift from negative to positive, which is called action potential . This process continues as the impulse travels along the axon via and reaches the axon terminal which will then stimulate other neurons at its dendrites. The most common impulse conduction is when our finger touches a hot item, like a skillet or the eye on the stove. Upon touching the item, a nerve impulse sends quick communication between nerve cells in the finger and the brain to make us react by withdrawing the finger, therefore preventing serious injury. In impulse conduction, neural impulses are transmitted from the sensory receptors to the dorsal root
