The nervous system is small, yet it is perhaps the most complex of the body’s systems. Its function is to detect and integrate a complex array of sensory information and then respond to this information by sending signals that control both movement and the release of chemical messengers, such as neurotransmitters and hormones, throughout the body. The nervous system is also responsible for the higher mental faculties, such as thought, behavior, and memory. This learning program begins with an introduction to the cells of the nervous system. You will then learn about the main components of neurons and about the classification of neurons and neuroglia. You will also learn about the major structures and components of the central nervous system (CNS) and of the peripheral nervous system (PNS).
Upon completion of this learning program, you will be able to::
Identify the cells and cellular components of the nervous system.
Identify the major components of the central nervous system.
Identify the major components of the peripheral nervous system.
