Neurl control -
Neural (Nervous) system is a system of highly specialised nerve cells, nerve fibres and organs (called receptors), that
coordinate and control the activities of different parts of the body. This is done by converting the internal and external
stimuli of environmental changes into the form of electrical impulses (a process called transduction) and transmit them
to other specialised cells called effectors (muscles and glands) to react accordingly. Between the receptors and
effectors are present the conducting cells of the nervous system, the neurons.
Overall function of nervous system is to collect information about the external conditions in relation to the body's
internal state, to analyse this information and to initiate appropriate responses to satisfy certain needs (maintain homeostasis) i.e., coordination. The most important need is survival. The nerves do not form one single system, rather
they form several systems, which are interrelated i.e integration. Some of these are physically separate, others are different in function only. Thus, nervous system performs two functions, coordination and integration.
