The Basic Elements of Behavior The human body is a tremendous creation that is quite capable of performing a multitude of multifaceted movements and thoughts. In addition to its’ ability to move and think, the human body also allows numerous senses to become involved throughout ones daily routine. A person’s ability to think, remember, and experience emotion are all results of the body’s basic elements of behavior. Although the basic elements of behavior are indeed a very complicated system, one must identify the different elements and discuss how they unite to form a very distinctive and efficient system. The body’s

The structure of the neuron include three unique parts: dendrites, axons, and their terminal buttons. The dendrites are the cluster of fibers that branch out at one end of the neuron in order to receive messages form other neurons. The axons are situated on the opposite end of the cell body with its long, slim tube like extensions that send messages to other neurons. The neuron also consists of terminal buttons that store and release neurotransmitters. These buttons are small bulges at the end of the axon and their job is to channel the impulses that the dendrites detect from other neurons. Equally important are the axons which have a protective coating called the myelin sheath that prevents short circuiting with other neurons, allowing the electrical impulses to flow freely through them. This myelin sheath consists of fat and protein that encloses the axon to provide the necessary insulation to keep messages flowing successfully without interruption. According to the text, “ those axons that carry the most important and urgently required information have the greatest concentrations of myelin” (Feldman, 2009, p.62). This enables the impulses to travel at different speeds; they are able to travel from 2 to 225 miles per hour. The All or none law simply stated says that as the electrical impulse travels along the axon, the neuron will fire if it has enough force to produce an electrical charge. A neuron is considered to be in a passive state when it is
