Where is the Tigger zone on a unipolar neuron?
The "Tigger zone" in a unipolar neuron is the initial segment of the axon where action potentials are generated. Here, graded potentials from the dendrites accumulate and if they reach a certain threshold, an action potential is triggered.
Which type of cell is composed of one dendrite and one axon and is found in the eye and nose a. pseudo-unipolar neuron b. Schwann cell c. bipolar neuron d. multipolar neuron?
bipolar neuron
What anatomical characteristic determines wether a particular neuron is classified as unipolar bipolar or multipolar?
The location of dendrite and axon: If dendrite and axon emerge from same process, the neuron is unipolar. If dendrite and a single axon emerge from opposite ends of the soma, the neuron is bipolar. If the neuron has more than 2 dendrite it is called multipolar.
Is a association neuron unipolar?
No.Association neurons, or interneurons, connect 2 or more neurons and therefore are bipolar or multipolar. An example is the unipolar (or pseudounipolar) sensory neuron that connects, or forms a synapse, with a dorsal horn neuron which is an interneuron that connects with another neuron in the brainstem, i.e. in the geniculate or cuneate nuclei. Interneurons provide a point where information can be modulated, i.e. a stimulus can be excited or inhibited by input from other neurons.Unipolar neuron cell bodies are located in the dorsal root ganglia that receive afferent information from the periphery and transmit that information to the dorsal horn of the spinal cord. Because most authors report these neurons do not truly have only one process, but have a fused central and peripheral process, they are often referred to as pseudounipolar.
The synaptic terminal of a sensory nueron is located where?
The synaptic terminal of a sensory neuron is located either in the dorsal root ganglion (if it is a pseudo-unipolar neuron) or directly in the spinal cord (if it is a bipolar neuron). This is where the sensory neuron connects with other neurons to transmit sensory information to the central nervous system.
What neuron types are unipolar?
Small ones
What classified as an unipolar neuron?
Afferent
Neuron type in dorsal ganglion?
unipolar (pseudounipolar)

What is the 3 types of neuron?
one type of neuron is the motor neuron

The most common type of neuron found in the central nervous?
The most common type of neuron found in the central nervous system is the multipolar neuron. These neurons have many dendrites and a single axon extending from the cell body. Multipolar neurons are involved in processing and transmitting information in the brain and spinal cord.
What type of neuron is in the nervous system?
There are 3 types, the motor neuron, the sensory neuron, and the interneuron
