MORPHOLOGICAL AND FUNCTIONAL CHARACTERISTICS OF NEURONS AND THE MECHANISM OF SYNAPTIC TRANSMISSION OF NERVE IMPULSES

Аннотация

Neurons are highly specialized cells that serve as the building blocks of the nervous system. Their unique morphology—featuring dendrites, a cell body, and a long axon—enables them to transmit signals with precision and speed. This paper discusses the structural classifications of neurons, including their functional roles in sensory and motor pathways. It also explores the physiological process of action potential generation, highlighting the role of ion channels and membrane depolarization. Furthermore, the paper explains how synaptic transmission occurs, detailing the release and effect of neurotransmitters in chemical synapses. By synthesizing insights from anatomical and physiological sources, this study provides a comprehensive understanding of how neurons maintain communication within the human body and how dysfunctions in these processes can lead to neurological disorders.
