The function of the axon is to transmit information to different neurons, muscles, and glands. In certain sensory neurons ( pseudounipolar neurons ), such as those for touch and warmth, the axons are called afferent nerve fibers and the electrical impulse travels along these from the periphery to the cell body and from the cell body to the ...
The extensive dendritic tree of two hippocampal pyramidal neurons (magenta) with all incoming synapses genetically labeled (green spots). [2]Dendrites are one of two types of cytoplasmic processes that extrude from the cell body of a neuron, the other type being an axon.
Axon terminals are specialized to release neurotransmitters very rapidly by exocytosis. [1] Neurotransmitter molecules are packaged into synaptic vesicles that cluster beneath the axon terminal membrane on the presynaptic side (A) of a synapse.
The axon hillock is a specialized part of the cell body (or soma) of a neuron that connects to the axon.It can be identified using light microscopy from its appearance and location in a neuron and from its sparse distribution of Nissl substance.
In neuroscience, the axolemma (from Greek lemma 'membrane, envelope', and 'axo-' from axon [1]) is the cell membrane of an axon, [1] the branch of a neuron through which signals (action potentials) are transmitted.

The protein composition of neurofilaments varies widely across different animal phyla. Most is known about mammalian neurofilaments. Historically, mammalian neurofilaments were originally thought to be composed of just three proteins called neurofilament protein NF-L (low molecular weight; NF-L), NF-M (medium molecular weight; NF-M) and NF-H (high molecular weight; NF-H).
Schwann cells or neurolemmocytes (named after German physiologist Theodor Schwann) are the principal glia of the peripheral nervous system (PNS). Glial cells function to support neurons and in the PNS, also include satellite cells, olfactory ensheathing cells, enteric glia and glia that reside at sensory nerve endings, such as the Pacinian corpuscle.
