Neurons are the main components of nervous tissue in all animals except sponges and placozoans. Plants and fungi do not have nerve cells. Molecular evidence suggests that the ability to generate electric signals first appeared in evolution some 700 to 800 million years ago, during the Tonian period.

2024年1月16日 · A neuron is a nerve cell that processes and transmits information through electrical and chemical signals in the nervous system. Neurons consist of a cell body, dendrites (which receive signals), and an axon (which sends signals). Synaptic connections allow communication between neurons, facilitating the relay of information throughout the body.

2022年2月28日 · Neurons, also known as nerve cells, send and receive signals from your brain. While neurons have a lot in common with other types of cells, they’re structurally and …

2025年2月25日 · Neurons are information messengers. They use electrical and chemical signals to send information between different areas of the brain, as well as between the brain, the spinal cord, and the entire body.

2023年7月24日 · Neurons are electrically excitable cells that transmit signals throughout the body. Neurons employ both electrical and chemical components in the transmission of information. Neurons are connected to other neurons at synapses and connected to effector organs or cells at neuroeffector junctions.

Neurons are the structural and functional unit of the nervous system. All neurons have three different parts – dendrites, cell body and axon. The neuron structure is specially adapted to …

一般来说，传入神经元的神经纤维，进入中枢神经系统后与其它神经元发生突触联系以辐散为主，即通过轴突末梢的分支与许多神经元建立突触联系，可引起许多神经元同时兴奋或抑制，以扩大影响范围。 神经冲动由胞体经轴突传至末梢，使肌肉收缩或腺体分泌。 传出神经纤维末梢分布到骨骼肌组成运动终板；分布到内脏平滑肌和腺上皮时，包绕肌纤维或穿行于腺细胞之间。 在反射弧中，一般与中间神经元联系的方式为聚合式，即许多传入神经元和同一个神经元构成突触，使 …
