Readings to Accompany “Nerves” Worksheet (adapted from France
... Nerves are fragile and can be damaged by compression, tension, or cutting. Injury to a nerve can stop signals to and from the central nervous system, causing impaired muscle function and loss of (or abnormal) sensation in the injured area. When a nerve is cut, both the nerve and its insulating myeli ...

Nervous System Neurons And Synapses
... The nodes of Ranvier represent an area along the axon where there is an absence of myelin. Because ions can cross the membrane only at the nodes, only a node can respond to a depolarizing stimulus. Action potentials appear to “leap” or “jump” from node to node. A process called salutatory conduction ...

This difference exists because there are more positive ions outside the cell and fewer positively charged ions inside the cell. 2. Part of th ...

Introduction to the Central Nervous System
... While the brain comprises only about 2% of body weight, it receives 15% of the blood supply. This is because neural activity is energetically expensive and requires a high metabolic rate to keep up with the demand.
