Abstract:
Neuronal trafficking is crucial to the formation and dynamics of presynaptic and postsynaptic structures and the development and maintenance of axonal and dendritic processes. The mechanism for delivering specific organelles and synaptic molecules in axons and dendrites primarily depends on molecular motor proteins that move along the cytoskeleton. Adaptor proteins, regulatory molecules and local signaling pathways provide additional layers of specificity and control over bidirectional movement, polarized transport and cargo delivery. Here we review recent advances and emerging concepts related to the transport machinery of crucial neuronal components, such as mitochondria and presynaptic cargoes, and the mechanisms that modulate their polarized axo-dendritic sorting and synaptic delivery.

Neurons: The Axon
The axon attaches to the cell body at a cone-shaped elevation called the axon hillock. The initial part of the axon, closest to the hillock, is known as the initial segment....

Neurochemical Transmission: Sites of Drug Action
Propagation of Action Potentials
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...
Synaptic Signaling
Synaptic Signaling
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.
The presynaptic neuron fires an action potential that...
