Nerve
A nerve is an enclosed, cable-like bundle of axons (the long, slender projections of neurons) in the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses...

Neuroscientist Shows What Fasting Does To Your Brain And Why Big Pharma Won’t Study It
Fasting kills off old and damaged immune cells, and when the body rebounds,… it uses stem cells to create brand new, completely healthy cells. Wow…! What an opportunity to rebuild your body  by leavin...
Stanford Engineers Create Artificial Skin That Can Send Pressure Sensation To Brain Cell
Stanford engineers have created a plastic "skin" that can detect how hard it is being pressed and generate an electric signal to deliver this sensory input directly to a living brain cell. Zhenan Bao,...
Whales Use 'Bungee-Cord' Nerves To Capture Fish - And Their Onlinelies Inflate Like 'Water Balloons' As They Swallow Shoals Of Prey
Rorqual whales have nerves in their mouth that stretch 'like a bungee cord' to help the animals hunt fish. The elastic nerves, which can more than double their length, allow the whales to turn their b...

Flashy neurons may get the attention, but a class of cells called glia are behind most of the brain's work-and many of its diseases
Nerve fascicle
A nerve fascicle or fasciculus is a small bundle of nerve fibers, enclosed by the perineurium; if the nerve is of small size, it may consist only of a single fasciculus; but if large, the fasciculi ar...
Epineurium
The epineurium is the outermost layer of dense irregular connective tissue surrounding a peripheral nerve. It usually surrounds multiple nerve fascicles as well as blood vessels which supply the ner...
Neuroglia
Glial cells, sometimes called neuroglia or simply glia (Greek γλοία "glue"; pronounced in English as either /ˈɡliːə/ or /ˈɡlaɪə/), are non-neuronal cells that maintain homeostasis, form myelin, and pr...

Action potential
In physiology, an action potential is a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in...

Sensory nerve
A sensory nerve is an enclosed, cable-like bundle of sensory nerve fibers in the peripheral nervous system.
Sensory receptor
In a sensory system, a sensory receptor is a sensory nerve ending that responds to a stimulus in the internal or external environment of an organism. In response to stimuli, the sensory receptor initi...

Motor neuron
A motor neuron (or motoneuron) is a nerve cell (neuron) whose cell body is located in the spinal cord and whose fiber (axon) projects outside the spinal cord to directly or indirectly control muscles....
Neuromuscular junction
The neuromuscular junction connects the nervous system to the muscular system via synapses between efferent nerve fibers and muscle fibers, also known as muscle cells. As an action potential reaches t...

Spinal nerve
A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human there are 31 pairs of spinal nerves, one on each side of the ver...

Nerve injury
Nerve injury is injury to nervous tissue. There is no single classification system that can describe all the many variations of nerve injury. Most systems attempt to correlate the degree of injury wit...

Neuroregeneration
Neuroregeneration refers to the regrowth or repair of nervous tissues, cells or cell products. Such mechanisms may include generation of new neurons, glia, axons, myelin, or synapses. Neuroregeneratio...
Myelin sheath gap
The nodes of Ranvier also known as myelin sheath gaps, are the gaps (approximately 1 micrometer in length) formed between the myelin sheaths generated by different cells. A myelin sheath is a many-l...

Sacral splanchnic nerves
Sacral splanchnic nerves are splanchnic nerves that connect the inferior hypogastric plexus to the sympathetic trunk in the pelvis.
The sacral sympathetic nerves arise from the sacral part of the ...
