Neuron
the basic unit of the nervous system, has four functional zones:
What is Neuron?
This neuron is large, has long axons, and stimulates muscles.
What is Motor Neurons?
small bubbles in presynaptic axon terminals that contain a neurotransmitter, a specialized chemical.
What is Synaptic Vesicles?
cone-shaped area of the cell body that gives rise to the axon.
What is Axon Hillock?
assist neuronal activity by providing raw materials, chemical signals, and structure and also participate in information processing.
What is Glial Cells?
A zone where dendrites receive information from other cells.
What is Dendrites?
This neuron has various shapes that best respond to specific environmental stimuli, such as light, odor, or touch.
What is Sensory Neurons?
What is Neurotransmitter receptors?
a branch of an axon that also ends in terminals.
What is Axon Collateral?
Two glial cell types wrap around axons to provide fatty insulation later
What is Myelin?
A zone the cell body integrates the information it receives.
What is Soma?
This neuron has tiny axons and analyzes input from one set of neurons. and communicate with others.
What is Interneurons?
refers to the continual remodeling of neuronal connections.
What is Neural Plasticity?
the bidirectional movement of materials within an axon. This transport is different from the conduction of action impulses...
What is Axonal Transport?
form the myelin sheaths within the brain and spinal cord.
What is Oligodendrocytes?
A zone where output information is conducted away from the cell body as an electrical impulse.
What is Axon?
The longest motor neurons is about how many inches (on average)
What is 36?
Information is transmitted from the presynaptic neuron to the __________?
What is Postsynaptic Neuron?
star-shaped cells with many processes that stretch around and between neurons and sometimes blood vessels.
Important structural roles and chemical roles!
What is Astrocytes?
provide myelin to neurons outside the brain and spinal cord.
What is Schwann Cells?
A zone at the end of the axon that communicates activity to other cells.
What is Axon Terminals?
Neurons can be classified into three different types. Name them.
What is Multipolar neurons, Bipolar neurons, and Unipolar neurons?
the gap that separates the membranes.
What is Synaptic Cleft?
tiny, mobile cells that remove debris from injuries or dead cells.
What is a Microglial?
gapes between sections of myelin where the axon is exposed.
What is the Nodes of Ranvier?
