What is central nervous system explain briefly?
What is the central nervous system? The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
What are the main parts of the central nervous system?
The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
What are the three functions of the central nervous system?
The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.
What is an example of the central nervous system?
The central nervous system consists of the brain, the brainstem, and the spinal cord. The peripheral nervous system includes the cranial nerves, the spinal nerves, the sympathetic nervous system, and the parasympathetic nervous system. The spinal cord is continuous with the brain and lies caudally to it.
What are the three components of nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
What are the 7 main parts of the central nervous system?
The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).
Do you know all the organs of the nervous system?
Organs Nervous system – The nervous system is responsible for carrying messages from the brain to various parts of the body. Respiratory system – The respiratory system is responsible for breathing. Cardiovascular or circulatory system – The cardiovascular system carries blood throughout the body to help bring nutrients to various other organs.
What is the anatomy and physiology of the nervous system?
Summary of Nervous system anatomy and physiology. Nervous system anatomy and physiology. The nervous system is composed of the central nervous system, comprising the brain and the spinal cord, and the peripheral nervous system, comprising sensory receptors, sensory nerves, and ganglia outside the central nervous system.
How does the nervous system work in the human body?
The nervous system works through an interconnected network of billions of neurons. These neurons transmit information in the form of nerve impulses, across the nervous system and thus, coordinate the various functions of the body.
What is the development of the nervous system?
The development of the nervous system, or neural development, refers to the processes that generate, shape, and reshape the nervous system of animals, from the earliest stages of embryonic development to adulthood. The field of neural development draws on both neuroscience and developmental biology…
