Medically reviewed by Steven Gans, MD The peripheral nervous system (PNS) is the system of nerves and ganglia outside the ...

The nervous system is broadly divided into two sections ... or other signals via receptors or through gap junctions (direct connections between two membranes), axons that propagate action potentials ...

But neurons are not alone in the brain or elsewhere in the nervous system: Brain cells called glia play various supporting roles to keep the system running smoothly. Between the axon of a ...

After injuries, Schwann cells become the 'repair task force' that restores axons The peripheral nervous system largely owes its ability to regenerate to the high level of plasticity of Schwann cells.

The peripheral nervous system largely owes its ability to regenerate ... provide the myelin sheath that protects the axons of nerve cells. Schwann cells become active immediately after an injury ...

The pathway of the visual system has been the most deliberately studied nervous subsystem. Therefore, it presents a working model to gain knowledge of how axons migrate through intermediate ...

These axons extend over distances long and short ... Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and ...

A long fibre (axon) which is insulated by a fatty (myelin ... These move towards the central nervous system (CNS). The CNS is the brain and spinal cord. It coordinates the responses.

New Generation Software Expected to Drive Best-In-Class Radiosurgery Brain Tumor Treatments ZAP Surgical Systems, Inc., a global leader in non-invasive robotic brain surgery, today announced the ...

Dr. Rasband's team is discovering the functional organization of axons in health as well as disease or injury. The generation, propagation, and modulation of electrical signals in the nervous system ...
