26 de abr. de 2021 · The role of a nerve cell is to receive information from cells and transmit this information to other cells. There are three different types of nerve cells in the human body and, together, they detect and interpret information about our external environment before triggering responses to these stimuli.
These include nerve cells (or neurons) and glial cells (or glia). Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials , which allow them to quickly transmit information over long distances.
Within a nervous system, a neuron, neurone, or nerve cell is an electrically excitable cell that fires electric signals called action potentials across a neural network. Neurons communicate with other cells via synapses , which are specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the ...
Nerve Cells. Despite the specific molecular, morphological, and functional features of any particular nerve cell type, the basic structure of neurons resembles that of other cells. Thus, each nerve cell has a cell body containing a nucleus, endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, and other organelles that are essential ...
21 de dic. de 2023 · The neuron (or nerve cell) is the functional unit of both the central nervous system (CNS) and the peripheral nervous system (PNS). The basic functions of neurons can be summarized into three main tasks: receiving signals, integrating these signals and transmitting the signals to target cells and organs.
The cell body contains the nucleus and other cell organelles. Dendrites extend from the cell body and receive nerve impulses from other neurons. The axon is a long extension of the cell body that transmits nerve impulses to other cells.
Una célula nerviosa (neurona) se compone de un gran cuerpo celular y de fibras nerviosas (una prolongación alargada denominada axón para enviar impulsos y habitualmente muchas ramificaciones denominadas dendritas para recibirlos).
