Sensory neurons carry information from ______ to the ________.
Central nervous system; sensory receptors
Sensory receptors; Central nervous system
Central nervous system; muscle gland
Insertion; origin
Provides nutrients to neurons, give synapsis structural support, and block toxic substances
Ependymal cells
Astrocytes
Microglia
Schwann cells
Produce cerebrospinal fluid in brain and spinal cords
Ependymal cells
Astrocytes
Microglia
Schwann cells
Scavenge and degrade dead cells, protecting the brain from invading micro organisms
Ependymal cells
Astrocytes
Microglia
Schwann cells
From myelin sheaths around axons in the CNS
Schwann cells
Oligodendrocytes
From myelin sheaths around axons in the PNS
Schwann cells
Oligodendrocytes
Motor neurons carry information from ______ to the ________.
Central nervous system; sensory receptors
Sensory receptors; Central nervous system
Central nervous system; muscle gland
Insertion; origin
Transmit impulses away from cell body, vary in length, and the larger the diameter = the faster the conduction
Axons
Axon terminal
Dendrites
Myelin sheaths
Contain vesicles with neurotransmitters, separated from the next neuron or effector by the synthetic cleft, and has synthetic knob and synapsis within
Axons
Axon terminal
Dendrites
Myelin sheaths
There are 100s per cell, receptive side conduct impulses toward the cell body, and immense surface area for reception
Axons
Axon terminal
Dendrites
Myelin sheaths
Protects and insulates fibers, and also increases speed of transmission through a process called saltatory conduction
Axons
Axon terminal
Dendrites
Myelin sheaths
What is a neurotransmitter?
Chemicals which transmit electrical impulses
Chemicals which transmit neurological impulses
Chemicals which transmit synaptic impulses
Chemicals which transmit synapse impulses
A site where action potential is converted into a chemical message
Synapse
Synaptic cleft
Synaptic knob
The entire junction between two neurons or a nerve and another structure
Synapse
Synaptic cleft
Synaptic knob
The space that separates a neuron and its target cell at a chemical synapse
Synapse
Synaptic cleft
Synaptic knob
Plasma membrane of the neuron
Dendrites
Cell body
Neurilemma
Neurons
The control center that contains metabolic/biosynthesis
Dendrites
Cell body
Neurilemma
Neurons
Why is the outer covering (neurilemma) of a neuron so important?
The site of electrical signaling
Does nor contain centrioles
Plays a crucial role in cell interactions
Receptive sites toward the cell body
Conduct electrical impulses, cannot replicate, and have longevity
Neurons
Neuroglia
Produce myelin, can replicate but cannot conduct, and provide structural support
Neurons
Neuroglia
