Essentially, nerve cells, also known as a neurons, are the active component of the nervous system. Neurons communicate with each other as well as with other cells through electric signals (nerve impulses), which in turn allows effector organs to respond to the appropriate stimuli. ...
Nerve Impulses Neuron Physiology Action Potentials- nerve impulses which are sent by a change in electrical charge in the cell membrane. Depends on ions: Sodium (Na+) highly concentrated outside of cells Potassium (K+) highly concentrated inside cells Ion movement Ions move from high concentration...
The unique structure of nerve cells allows the conduction of nerve impulses.. The structure in nerve cells that receives signals from other nerve cells is called View Solution Assertion : Hair cells on the basilar membrane (organ of Corti) are responsible for hearing. Reason : Pressure waves,...
transmission thought to play a part in conditions such as Parkinson’s disease. More immediately, the work could lead to new drugs for treating myasthenia gravis, a potentially fatal disease affecting one in 30 000 people, and caused by the failure of the nervous system to transmit impulses to...

Anerveis an enclosed, cable-like bundle of peripheral axons (the long, slender projections of neurons). A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons. Nerves are found only in the peripheral nervous system. In the central ...
in another neuron. Nerve impulses are received at neuronal dendrites, passed through the cell body, and are carried along the axon to the terminal branches. Since axons can have numerous branches, nerve impulses can be transmitted to numerous cells. These branches end at junctions called synapses...
(1) Nerve Impulses What is it? Nerve Impulse = Electrical Current Messages sent to and from neurons Used to respond to stimuli Ultimately maintains homeostasis Nerve Impulse = Electrical Current Comes from the flow of positively charged ions Ions move across the neuron’s membrane Also called an...
Either of the tenth and longest of the cranial nerves, passing through the neck and thorax into the abdomen and supplying sensation to part of the ear, the tongue, the larynx, and the pharynx, motor impulses to the vocal cords, and motor and secretory impulses to the abdominal and thoracic...
