The first major function of the nervous system is sensation-receiving information about the environment to gain input about what is happening outside the body (or, sometimes, within the body).The process of integration combines sensory perceptions and higher cognitive functions such as memories, learning, and emotion to produce a response. Some regions of the nervous system are termed integration or association areas.Sensory input needs to be integrated with other sensations, as well as with memories, emotional state, or learning (cognition). But there is a third function that needs to be included. This system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses).Enteric-controls digestive system activity.Parasympathetic-control activities that conserve energy expenditures.Sympathetic-control activities that increase energy expenditures.Autonomic Nervous System-controls involuntary muscles, such as smooth and cardiac muscle.Somatic Nervous System-controls skeletal muscle as well as external sensory organs.Motor Nervous System-carries information from the CNS to organs, muscles, and glands.Sensory Nervous System-sends information to the CNS from internal organs or from external stimuli.The peripheral nervous system is divided into the following sections: Human Reproductive system- Formation of Gametes, Organs Overview and Function This system has exposed nerves and more vulnerable to injury.Īlso Read : Human Reproductive system- Formation of Gametes, Organs Overview and Function The peripheral nervous system provides a pathway of communication between the central nervous system and the rest of the body, this is also a primary function of the peripheral nervous system. Peripheral nervous system– It consists of cranial nerves, spinal nerves and billions of sensory and motor neurons.This system has a protective covering of bone. Central nervous system – It is composed of the brain and spinal cord that received, process and send the information to the peripheral nervous system.The central and the peripheral nervous system. This system is divided into two parts i.e. The nervous system derives its name from nerves, which are cylindrical bundles of fibers (the axons of neurons), that emanate from the brain and spinal cord, and branch repeatedly to innervate every part of the body. The nervous system also responsible for monitoring and coordinates the internal organ function and responds to changes in the external environment. This system performs and responsible for various functions like sending, receiving, and interpreting information from all parts of the body.
The nervous system is the combination of the brain, spinal cord and the complex network of neurons.
