Provide physical and metabolic support to neurons
Where are neurotransmitters released from to communicate with other cells?
Axon terminals
What part of the neuron transmits signals away from the cell body?
Axon
What is the main function of receptor cells in the nervous system?
Receive neurotransmitters on the surface of target cells and initiate a response
What type of signal transmission occurs within neurons?
Electrical signals (action potentials)
What is the junction between two neurons or between a neuron and a target cell called?
Synapse
What is the function of oligodendrocytes in the CNS and Schwann Cells in the PNS?
Produce myelin to insulate axons
What is the function of ependymal cells?
Produce cerebrospinal fluid for buoyancy and protection
What is the function of microglia?
Act as immune cells of the CNS and remove debris through phagocytosis
What is the function of satellite cells in the PNS?
Surround neurons in peripheral ganglia, providing structural support and regulating nutrient exchange
What is the function of radial glia during embryonic development?
Serve as guides for migrating neurons during embryonic development
Which glial cell provides metabolic support to neurons?
Astrocytes
This quiz provides an overview of how the nervous system communicates information in the body, focusing on the function and structure of neurons. It covers the transmission of electrical impulses, the role of different neuron components such as the cell body, dendrites, axon, and axon terminals, as well as the release of neurotransmitters for communication.
