The Biological foundation of Psychology involves the electrical and chemical processes in the nervous system that cause us to feel‚ have fears‚ and develop thoughts. There are many biological factors that can influence psychological functioning. From the neuron to the different parts of the nervous system‚ each can impact mental processes and behavior. Genetics and evolution can also influence psychological functioning. Genetics and evolution

The nervous system which is made up of the sensory and control apparatus consisting of a network of nerve cells that control our body functions. There are two main nervous systems: Central Nervous System and the Peripheral Nervous system. Your central nervous system (CNS) consists of your brain and spinal cord. Where as the Peripheral Nervous system (PNS) consists of sensory neurons running from stimulus receptors that inform
