15 Questions
What is the basic unit of the nervous system?
Neurons
What type of stimuli may provoke neuron activity?
Chemical stimuli
What do dendrites do in a neuron?
Receive impulses from other cells
What are axons responsible for in a neuron?
Conducting nerve impulses away from cell bodies
Which type of cells are the conducting cells of the nervous system?
Neurons
Neurons receive and transmit electrochemical nerve impulses through threadlike nerve fibers called dendrites.
False
The nervous system coordinates all body functions, enabling a person to adapt to changes in external environments only.
False
Neuroglia are the conducting cells of the nervous system.
False
Neuron activity may only be provoked by chemical stimuli.
False
What are the two main types of cells in the nervous system?
Neurons and Neuroglia
Axons conduct nerve impulses toward the cell body.
False
What is the function of dendrites in a neuron?
Dendrites receive impulses from other cells and conduct them toward the cell body.
What stimuli may provoke neuron activity?
Mechanical stimuli, thermal stimuli, and chemical stimuli
How does the nervous system enable a person to adapt to changes in the internal and external environments?
By coordinating all body functions
What is the basic unit of the nervous system?
