Nervenzelle einfach erklärt: Aufbau & Funktion
Biologie - simpleclub・2 minutes read
Neurons are the building blocks of the nervous system, with dendrites and axons facilitating communication through synapses. Axons, insulated by myelin sheaths, transmit signals between neurons, varying in length and diameter to form nerve fibers that enhance signal conduction speed.
Insights
- Neurons are made up of a cell body (peri carion) and dendrites that communicate with other neurons through synapses, while the axon transmits signals between neurons, some of which are insulated by myelin sheaths to increase signal conduction speed.
- Axons in neurons are responsible for transmitting signals and can vary greatly in length and diameter, forming nerve fibers when combined with myelin sheaths, ultimately accelerating the transmission of signals in the nervous system.
