Cerebrospinal fibers
Cerebrospinal fibers
Cerebrospinal fibers (pronunciation: /ˌserəbrōˈspīnl ˈfībərs/) are a group of nerve fibers that connect the brain and the spinal cord, facilitating communication between the two.
Etymology
The term "cerebrospinal" is derived from the Latin words cerebrum meaning brain, and spinalis meaning of the spine. The term "fibers" is derived from the Latin fibra, meaning thread or filament.
Function
Cerebrospinal fibers play a crucial role in transmitting neural signals from the brain to various parts of the body, and vice versa. They are involved in a wide range of bodily functions, including motor control, sensory perception, and reflexes.

- Axon: A long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body.
- Dendrite: The branched projections of a neuron that act to propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.
- Myelin: A fatty substance that surrounds and insulates the axons of some neurons, enhancing the speed at which electrical impulses are transmitted.
- Synapse: The junction between two neurons or between a neuron and a muscle where electrical or chemical signals are transmitted.
