Projection fiber

Projection fiber (pronunciation: /prəˈdʒɛkʃən faɪbər/) is a type of neural fiber that connects the cerebral cortex to the rest of the nervous system and the body.

Etymology

The term "projection fiber" is derived from the Latin "proiectio" meaning "throwing forward" and the Old English "fibre" meaning "thread". This refers to the function of these fibers in transmitting information from the brain to the rest of the body.

Function

Projection fibers are responsible for transmitting neural signals from the brain to the rest of the body, and vice versa. They are a key component of the motor system, allowing the brain to control movement, and the sensory system, allowing the brain to receive information about the body's environment.

Types

There are two main types of projection fibers: efferent fibers and afferent fibers. Efferent fibers carry signals from the brain to the rest of the body, while afferent fibers carry signals from the body to the brain.

Related Terms

  • Neuron: The basic working unit of the brain, a specialized cell designed to transmit information to other nerve cells, muscle, or gland cells.
  • 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.
