Aortic Aneurysm

WHAT WENT WRONG?

A weakening in the wall of a portion of the aorta results in a balloon-like bulge as

blood flows through the aorta. The blood flow within this bulging area of the aorta

becomes very turbulent. Over time this turbulence can cause the dilated area to

increase in size, creating an aneurysm. The aneurysm can rupture causing a disruption

in blood flow to everything below the affected area, and may even result

in death.

Cardiovascular System

 

How the Cardiovascular System Works

The cardiovascular system is responsible for delivery of blood, which carries oxygen

and other nutrients, to the tissues of the body. The heart pumps the blood to

the body where it delivers nutrients and oxygen, picks up waste products, and then

returns to the heart.

Definitions and Terminology

A Drug

drug is defined as any chemical (substance) that can affect living processes (lehne , 2007)

Pharmacology 

Pharmacology is defined as the study of drugs and their interactions with living systems.(Lehne , 2007)

Clinical Pharmacology

Clinical Pharmacology is defined as the study of drugs in humans.It gives data,about indications,the potency ,doses and toxicity of drugs,for their safe clinical use.(Lehne , 2007)

Neurons

As we earlier discussed in our day to day physical activities the coordinating fun ction of our muscles to do those activities is a necessity.Have you ever considered how the muscles involved in those physical activities?When we consider this we can see that there is a scientific system to activate and coordinate the muscle to perfrom those activities.In this process it necessary for the body to transmit messages to eneble the muscles to produce the complex movements for  successful physical activity.Such messages are transmitted through specialized cells called neurons. Neurons are the basic elements of the nervous system.They are the cells that are specialized for communicating information.It is estimated that they are 100 -200 billion neurons in the brain itself (Feldman,1993)

Neurons have a basic structure of

     Cell body

     One axon

     One or more dendrites

Biology and Behaviour

The purpose of this study post is to help you Understand the biological basis of human behaviour.Hence, in this post you will have to study the biological structures of the body which influence behaviour such as the nervous systems functions in influencing behaviour.

You must understand that behaviour means actions of an individual as a result of biological , psychological and social interactions.

In other words, behaviour is a product of man’s biological ,psychological and socio-cultural environment.Biology means bodily structures or systems such as nervous system , muscular systems and its  functioning.

Cognative Model

“People are disturbed not by things,but by the views which they take of them”

The cognative model focus on how people acquire and interprets information and use it in problem solving.Each person develops schemata, which contain information about different domains in a person’s life, and assist in information processing  and strategy development.In the study of maladaptive behaviour,self-schemata are particularly important.

Humanistic model

The psychological model says that people are in a position to control their lives.Rejecting the views that behaviour is determined largely by automatic biological process , unconscious process of solely by environment it suggests that people are in control of their lives.Humanistic model stresses the role of psychology in enriching peoples’ lives and helping them self-fulfilment.Humanistic psychologists say that people are naturally inclined to develop towards higher levels of maturity and if they are given the opportunity they will strive to reach their full potential.Carl Rogers rejected the psychodynamic approach saying that it has given much emphasis to unconscious process.Rogers developed a new humanitarian theory called “self theory”.In theory he has mentioned that personality development is guided by each of has a personal need for positive regard.Abraham Maslow also  a famous psychologist who has contributed tremendously for the advancement of this model.His theory emphasized two things.
