What carries information to the soma?
Dendrites are specialized extensions of the cell body. They function to obtain information from other cells and carry that information to the cell body. Many neurons also have an axon, which carries information from the soma to other cells, but many small cells do not.
What conducts electrical currents away from the cell body?
The primary components of the neuron are the soma (cell body), the axon (a long slender projection that conducts electrical impulses away from the cell body), dendrites (tree-like structures that receive messages from other neurons), and synapses (specialized junctions between neurons).
What is the central nervous system responsible for?
The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
How do neurons conduct electrical impulses?
Neurons conduct electrical impulses by using the Action Potential. This phenomenon is generated through the flow of positively charged ions across the neuronal membrane. Neurons, like all cells, maintain different concentrations of certain ions (charged atoms) across their cell membranes.
Which structure transmits impulses to the soma quizlet?
Neurons are the cells that transmit nerve impulses between parts of the nervous system. Dendrites are extensions leading toward cell body that receives signal from other neurons and send them to the cell body. Part of neuron that holds the nucleus as well as other organelles, also called the soma.
What conducts electrical impulses away from the soma?
An axon, or nerve fiber, is a long slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron’s cell body or soma.
