Neurons have four specialized structures that allow for the sending and receiving of information: the cell body (soma), dendrites, axon and axon terminals (see lowest figure). Integrative part (cell body/soma), containing the nucleus and most of the cell's organelles, acting as the trophic center of the entire neuron The neuron is often thought of as the building block of the nervous system, and for good reason. Neuron: Structure. The neuron is the fundamental unit which makes up a nerve pathway, neural firing (neurotransmitter release) takes place at the level of the neuron, and many aspects of the physiology-behavior relationship can be explained in terms of activity at NEURON STRUCTURE AND CLASSIFICATION. The neuron is the structural and functional unit of the nervous system. How does their arrangement allow nerve impulses to travel very rapidly along axons? What is the potential for neurogenesis in the human brain? Most of a neuron’s organelles, In this article, we'll take a closer look at neurons, glia, and nervous systems. Neuron: Function. Define neurogenesis. Basic cellular processes occur in a neuron. The axon is the main conductingunit of the neuron, capable of conveying electrical signals along distancesthat range Relate neurons to different types of nervous tissues Networks of neurons with intricate connections form nervous systems. •Axon terminals •Synapse. Cell body or soma: The cell body is the portion of the cell that surrounds the nucleus and plays a major role in synthesizing proteins Neurons consist of cytoplasm (fluid found within the cell), mitochondria and other organelles. specialized in •Receiving •Transmitting •Processing Identify the three main parts of a neuron and their functions. What is a synapse? Ribosomesare where proteinsare pro duced, and mitochondria are responsible for metabolic activities that energise the cell Axon Usually a long process which often projects todistant regions of the nervous system. Describe the myelin sheath and nodes of Ranvier. Three basic partsCell bodyAxonDendrites. We'll see how the structure of neurons supports their function, and how they can be organized into Parts of the Nerve Cell and Their Functions Silvia Helena Cardoso, PhD [Cell body] [ al membrane][ tes] [Axon][Nerve ending]Cell bodyMain As such, neurons typically consist of four main functional parts which include the: Receptive part (dendrites), which receive and conduct electrical signals toward the cell body.
