building blocks of the human brain ‐ 100 billion neurons or brain cellspoint of connection between axon of one neuron and dendrite of another ‐ synapse or synaptic cleftbrainstem and limbic system, brain being more than a simple organ

neuron; conduction of the action potential In a myelinated axon, the myelin sheath prevents the local current (small black arrows)... Encyclopædia Britannica, Inc. invertebrate: nervous system Nervous systems of a flatworm (Planaria) and a grasshopper (order Orthoptera). ...
axon - the long extension of a neuron that carries nerve impulses away from the body of the cell. axon terminals - the hair-like ends of the axon cell body - the cell body of the neuron; it contains the nucleus (also called the soma) dendrites - the branching structure of a ...
Colello Anatomy & Neurobiology, Virginia Commonwealth University, Richmond, VA, USA Synonyms Nerve cell Neuron is the main signaling unit of the nervous system capable of processing and transmitting information via chemical and electrical synapses. These cells comprise a cell soma, and two kinds of ...

Multipolar nerve cells– These neurons have symmetrical dendrites that branch off a single axon. They are the most prevalent kind of neuron in the central nervous system. Purkinje nerve cells– Multiple dendrites branch out from the cell body of Purkinje neurons. Because they produce neurotransmitters...
axon also stretches from the cell body. It sometimes branches along its length but always branches at its microscopic tip. When the cell body of a neuron is chemically stimulated, it generates an impulse that passes from the axon of one neuron to the dendrite of another; the junction between...
The olfactory epithelium is a pseudostratified columnar epithelium overlying a lamina propria and consists of the following cell types: Basal cells: Act as stem cells Can differentiate into progenitors of the olfactory epithelium Sustentacular cells: support olfactory neuron function Olfactory gland ce...
axon terminal dendrites Branchlike parts of a neuron that are specialized to receive information. axon the neuron extension that passes messages through its branches to other neurons or to muscles or glands neuronal signaling deliver the message over long distances to a very specific cell ...
