Definition
Neuron structure refers to the specialized components of a neuron, including the cell body (soma), dendrites, axon, and axon terminals, which enable the transmission of electrical and chemical signals throughout the nervous system. These structures work together to facilitate communication between neurons and other cells.
Summary
Neurons are the fundamental units of the nervous system, responsible for transmitting information throughout the body. Each neuron consists of a cell body, dendrites, and an axon, which work together to process and relay signals. The communication between neurons occurs at synapses, where neurotransmitters play a key role in signal transmission. Understanding neuron structure and function is essential for grasping how the nervous system operates. This knowledge is foundational for exploring more complex topics such as neuroplasticity and neurotransmission, which further illustrate the dynamic nature of the brain and its ability to adapt and respond to various stimuli.
