Introduction of Human Behavior

• Psychology is the scientific study of human behavior. Psychologists have also studied human behavior in relation to different bodily changes and brain functions. Physiological psychologist studies biological factors affecting the behavior of an organism. In this chapter, we will study the structure and functions of a nerve cell, types of Nervous System and structure and function of Brain etc.

Relation between Human Behavior and Biology

• Cell is the basic unit of human body. Many cells combine to form tissue. Similarly many tissues form organs and from organ to organ systems are formed. These organ systems perform specific functions of our body. For e.g. digestive system perform the function of digesting food. Circulatory system circulates blood to different body parts. Our body has many such systems. Nervous system has very important role in determining human behavior. Nervous system receives sensations through sensory organs, carries these sensations to brain and the carries back the decisions taken by brain to related organs, muscles etc.
