Learning is the continuing process for human beings and other animals not only a situated at learning centres. The Learning processes are running in the environment and the societies and also the created circumstances. Learning is also creates the behaviour of animals. In this paper the associative learning behaviour in describing, the classical conditioning is the type of associative learning behaviour, which is described here with experiment of Pavlov. The learning is also    controlled by nervous system. In the Pavlov's experiment the senses are involve (hearing and salivation). All senses are controlled by nervous system. The behavioural study and physiology of nervous system both are functioning with together, hence the interrelationship between physiology of nervous system and Associative Learning Behaviour has been established.
