The Nervous System
The Nervous System is divided into Two Main Divisions: Central Nervous System (CNS) and the Peripheral Nervous System (PNS) Divisions of the Nervous System
The nervous system is comprised of two major parts, or subdivisions, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord. The brain is the body's "control center". The CNS has various centers located within it that carry out the sensory, motor and integration of data.
In our body the nervous system detects and responds to changes from normal functions both inside and outside the body. It is a complex system made up of the brain, spinal cord and the billions of neurons.
The organs of the nervous system can be divided into two groups. One group, consisting of the brain and spinal cord, forms the central nervous system (CNS). The other, composed of the nerves (bundles of axons) that connect the central nervous system to other body parts, is called the peripheral nervous system (PNS) (fi g. 9.2).
This chapter presents some basic information about the major structures of the nervous system and their in-terconnections, an area of study called neuroanatomy. It also includes a general discussion of the relationship between structure and function, an area of investigation known as functional neuroanatomy.
Explain the structural & the functional classifications of the nervous system. Define central nervous system & peripheral nervous system & list the major parts of each. 1- By detecting changes in internal and external environments >>> resulting in muscle, organ or gland response. 2- Higher functions : memory, learning and emotions.
the nervous system requires knowledge of neuronal and neuroglial cells’ structure and functions. This article, the first in a six-part series, reviews several basic aspects of cellular biology, anatomy and physiology of the nervous system. Anatomically, the nervous system can be subdivided into two: Central nervous system (CNS) – brain
The nervous system controls the functioning of the human body and is comprised of the brain, spinal cord, cranial nerves and spinal nerves. Along with the endocrine system, it is also responsible for regulating and maintaining body homeostasis.
Nervous System 1. Sensory input—gathering information Sensory receptors monitor changes, called stimuli, occurring inside and outside the body 2. Integration Nervous system processes and interprets sensory input and decides whether action is needed 3. Motor output A response, or effect, activates muscles or glands © 2018 Pearson Education, Ltd.
nervous system (PNS) and the central nervous system (CNS).These two in- teracting and communicating systems are in actuality a continuous entity. The peripheral nervous system effectively merges into the central nervous
