Function of mitochondria in axon terminal
WebSep 12, 2005 · In neurons, proper distribution of mitochondria in axons and at synapses is critical for neurotransmission, synaptic plasticity, and axonal outgrowth. However, mechanisms underlying mitochondrial trafficking throughout the long neuronal processes have remained elusive. WebJul 29, 2024 · Summary. An axon is a thin fiber that extends from a neuron, or nerve cell, and is responsible for transmitting electrical signals to help with sensory perception and movement. Each axon is surrounded by a myelin sheath, a fatty layer that insulates the axon and helps it transmit signals over long distances. 9 Sources.
