Phoenix Material Appendix B Structures of the Nervous System This activity will increase your understanding of the different structures of the nervous system and brain. During the Web activity‚ you will view a variety of structures of the brain and nervous system and label each with the appropriate term. You will use this document to write a description for the terms you used in the activity. As you conduct the Structures of the Nervous System activity‚ follow along with this Word document and

Artificial electrical stimulation of the nervous system is one of the foundations of neurotechnology. However‚ the use of electrical currents to stimulate the nervous system presents several challenges. It is difficult to achieve selective stimulation of only the targeted neurons without activating neighboring neurons. Further‚ electrochemical reactions at the electrode-tissue interface may lead to electrode dissolution or tissue damage. As an alternative‚ magnetic stimulation can be used to stimulate

Nervous System: an extensive network of specialized cells that carries information to and from all parts of the body. Neuron: the basic cell that makes up the nervous system and that receives and sends messages within that system. Dendrites: branchlike structures that receive messages from other neurons. Soma: the cell body of the neuron responsible for maintaining the life of the cell. Axon: tubelike structure that carries the neural message. Glial cells grey fatty cells that provide support for

Inside our brain‚ there is this system called the human nervous system. There are two types of nervous systems: the peripheral and central nervous systems. The peripheral nervous system includes the nerves connecting the central nervous system to the rest of the body. It has two subdivisions: somatic nervous system and autonomic nervous system. Somatic nervous system controls skeletal muscles and interacts with the external environment. An example is walking through a park. You are using your motor

The nervous system is made up of millions of neurons and interconnected nerves that are comparable to a wiring system. The nervous system is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The nervous system functions like a corporate giant. The CEO is the leader in the CNS and the officers and delegates are the PNS. The CNS gives the commands and the PNS follows the commands. The Central Nervous System The central nervous system (CNS) is

Anatomy of the Nervous System Structure of the Vertebrate Nervous System • Neuroanatomy is the anatomy of the nervous system. • Refers to the study of the various parts of the nervous system and their respective function(s). • The nervous system consists of many substructures‚ each comprised of many neurons. Structure of the Vertebrate Nervous System • Terms used to describe location when referring to the nervous system include: – Ventral: toward the stomach – Dorsal: toward the back –

The autonomic nervous system (ANS) consists of three main anatomical divisions: sympathetic‚ parasympathetic and enteric nervous systems. The sympathetic (SNS) and parasympathetic (PNS) systems provide a link between the central nervous system and peripheral organs. The sympathetic nervous system originates in the spinal cord. Specifically‚ the cell bodies of the first neuron (the preganglionic neuron) are located in the thoracic and lumbar spinal cord. Axons from these neurons project to a
