The nervous system is made up of millions of neurons and interconnected nerves that are comparable to a wiring system. The nervous system is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The nervous system functions like a corporate giant. The CEO is the leader in the CNS and the officers and delegates are the PNS. The CNS gives the commands and the PNS follows the commands. The Central Nervous System The central nervous system (CNS) is

of the brain and spinal cord. Neurones are found throughout the body with the majority found in the central nervous system. Neurones are specialized to process information in the body. Neurones convey this information to one another through the stimulation of a detector neurone. This causing a brief change in the electrochemical gradient resulting in the neurone moving away from its resting potential. This is known as an action potential. Once initiated the action potential travels the length of

Description This course is designed to expose you to the underlying physiological mechanisms of behavior. Physiological psychology is a complex but fascinating field of study. It explores the relationship between our biological systems and behavior. Structure and function of the nervous system from the neuron to the brain‚ as well as the interrelationships between the brain and such behaviors as eating‚ sleeping‚ learning‚ memory‚ emotion‚ and mental disorders will be discussed using examples from the behavior

animals’ and humans’ nervous systems is a necessary process to maximise the chances of survival. Neuronal and behavioural changes are closely linked to the environment surrounding animals and humans‚ as well as to their lifestyles. This essay will present some evidence that the nervous system of animals and humans have evolved as to maximize survival‚ by looking at specific elements of the nervous system on a cellular level‚ within the brain regions‚ through functioning pathways‚ systems and finally‚ behaviour

1. Explain both the anatomical and functional divisions of the nervous system. Include the subdivisions of each. The nervous system’s function is to monitor stimuli occurring inside and outside the body‚ process and interpret this sensory input‚ and respond by activating effector organs. It consists of the Central Nervous System (brain and spinal cord)‚ and the Peripheral Nervous System (neurons that carry messages to and from the CNS). 2. Describe the composition and function of the cell
