The nervous system is divided into two main parts -- the central nervous system and the peripheral nervous system. Explore an overview of the components and functions of these two divisions of the nervous system and understand their importance. Related to this QuestionWh...
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. Structurally, the nervous system has two components: the central nervous system and the peripheral...
Broadly speaking, the nervous system is divided into two components—central and peripheral. The central nervous system (CNS) comprises the brain and the spinal cord. The peripheral nervous system (PNS) comprises all of the nerves—cranial, spinal, and peripheral nerves, including the sensory and...
The main components of the circulatory system include the heart, blood, and blood vessels. This closed system relies on blood vessels to move blood around the body using the heart as the pumping mechanism. Arteries, veins, and capillaries are the three types of blood vessels. Arteries move...
(CNS) and peripheral nervous system (PNS). The CNS is comprised of the brain and spinal cord, and the PNS is composed of all the nerve fibers that extend out to all the parts of the body. The nervous system has three ...
Figure 4 the central nervous system and its components The central nervous system is divided into a number of important parts (see Figure 4), including the spinal cord, each specialized to perform a set of specific functions. Telencephalon orcerebrumis anewerdevelopment in the evolution of the ...
The brain and the spinal cord are the central nervous system, and they represent the main organs of the nervous system. The spinal cord is a single structure, whereas the adult brain is described in terms of four major regions: the cerebrum, the diencephalon, the brain stem, and the cerebe...
it we are able to use five senses to experience经历体验 the world around us, remember our past, and create for the future. We can do this thanks to our nervous system. Though there is still a lot we don't know, the level at which we now comprehend our brain and nervous system is ...
The Spinal Cord * The spinal cord sends messages to the brain. * The spinal cord is the part of the nervous system that connects the brain to the rest of the nervous system. The Brain * The brain controls everything in the body. * The brain is made of more than 10 billion nerves!
If we were able to magnify a view of individual neurons we would see that they are cells made from distinct parts (see Figure 2). The three main components of a neuron are the dendrites, the soma, and the axon. Neurons communicate with one another by receiving information through thedendri...
