PPT-The Nervous System Cell Structure

THE CENTRAL NERVOUS SYSTEM The nervous system is divided into two subunits Central nervous system CNS Brain spinal cord Peripheral nervous system Any part of nervous system outside of CNS. Structure and Function. 2. Input. (sensation). Output. (action). In order to understand behavior, we must understand the operating mechanism of the nervous system. What is the function of the nervous system?. Section 1 – Functions & Divisions of the Nervous System (pp. 386-387). This is your brain…. The Nervous System. And this is your brain – IN ANATOMY!!. Or better yet…. The Nervous System. Functions of the Nervous System. Functions of the Nervous System. Sensory input. Information gathered by sensory receptors about internal and external changes . Integration. Interpretation of sensory input. Motor output. Activation of effector organs (muscles and glands) produces a response. Peripheral Nervous System. Autonomic Nervous System. Allied Health I. Central Nervous System. Communication and coordination system of the body. Seat of intellect and reasoning. Consists of the brain, spinal cord, and nerves. The . function of the nervous system is:. To sense, interpret, and respond to internal and external environmental changes to maintain a steady state in the . body (homeostasis). The nervous system is divided into two major structures: . The Nervous System Central Nervous System Peripheral Nervous System Procedure A starting person will be chosen and will be given an object.

Once the teacher gives the signal, the start person will pass the object to their right. 1. Two main divisions. a. . Central Nervous System . (CNS) – consists of brain and spinal cord. b. . Peripheral Nervous System . (PNS) – includes nerves extending from . brain and . spinal . cord . neuron. : a nerve cell; receives signals from other neurons or sensory organs, processes these signals, and sends signals to other neurons, muscles, or bodily organs. the basic unit of the nervous system. The parts of central nervous system. The parts of brain. Neuron. is defined as the structural and functional unit of the nervous system. It is otherwise called nerve cell. Neuron is like any other cell in the body having nucleus and all the organelles in the cytoplasm. However, it is different from other cells by two ways: . Deemah. . Dabbagh. Nervous system. Composed of:. Brain (CNS). Spinal cord (CNS). Nerves to body parts (PNS. ). Function:. Maintain . homeostatis. by detecting stimuli in the environment.

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. .
