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.
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.
Neurons are classified on the basis of their structure as?
Neurons are classified into different types based on their structure as follows: multipolar neurons with many dendrites and a single axon, bipolar neurons with one dendrite and one axon, and unipolar neurons with a single process extending from the cell body that branches into dendrites and an axon.
Do the dendrites receive or release neurotransmitters?
You've sort of got it backwards: axon terminals initially release neurotransmitters into the synaptic cleft, from where they diffuse across the cleft and fit into receptor sites on ligand-gated sodium ion pores on the dendrites, causing those pores to open, allowing sodium ions into the dendrite, resulting in a change in the voltage of the dendrites membrane, which initiates the propagation of the signal along the dendrite and soma towards the axon hillock, where it may trigger an action potential in the axon.However, after the neurotransmitters have done their job at the dendrites, they can be "released" by the dendrites , as in let go of, to be re-absorbed, re-cycled, re-used by the axon terminals.The axons "give" the neurotransmitters to the dendrites as chemical messengers to convey the signal, and the dendrites "give them back" after the message has been received and conveyed onward.
What connective tissue is closest to the single neuron?
The connective tissue closest to a single neuron is the endoneurium. It surrounds individual axons within a nerve.
Does a single neuron possess dendrites?
yes

In addition to the nucleus cytoplasm and cell membrane a single neuron possesses what?
A single neuron also possesses dendrites, which receive signals from other neurons, and an axon, which transmits signals to other neurons or cells. Additionally, neurons have synaptic connections that allow them to communicate with other neurons or cells through neurotransmitters.
Part of neuron that sends message through the neuron?
The dendrites are the "input" portion of the neuron, collecting signals from other neurons. However, the axon is the "output" portion of the neuron, sending signals to other neurons.

Are dendrites and axons both armlike processes that extend from cell bodies?
Yes, it is true. Dendrites: Arm-like processes that extend from the cell body of all neurons which receive signals. They are short, tapering, and have branching extensions and are usually found close to the cell body. Dendrites are unmyelinated (slow conductors). Axons: Are single arm-like process that extends from the cell body of all neurons which generate and transmit nerve impulses. They can be long (up to ~ 1 meter) or short with diffuse branching at the end. Axons are myelinated (fast conductors).
Do the dendrites receive or release neurotransmitters?
You've sort of got it backwards: axon terminals initially release neurotransmitters into the synaptic cleft, from where they diffuse across the cleft and fit into receptor sites on ligand-gated sodium ion pores on the dendrites, causing those pores to open, allowing sodium ions into the dendrite, resulting in a change in the voltage of the dendrites membrane, which initiates the propagation of the signal along the dendrite and soma towards the axon hillock, where it may trigger an action potential in the axon.However, after the neurotransmitters have done their job at the dendrites, they can be "released" by the dendrites , as in let go of, to be re-absorbed, re-cycled, re-used by the axon terminals.The axons "give" the neurotransmitters to the dendrites as chemical messengers to convey the signal, and the dendrites "give them back" after the message has been received and conveyed onward.
The most type of neuron in the human body is?
Multipolar neurons This is the most common type of neuron, with one axon and many dendrites. Multipolar neurons are so-named because they have many (multi-) processes that extend from the cell body: lots of dendrites plus a single axon. Functionally, these neurons are either motor (conducting impulses that will cause activity such as the contraction of muscles) or association (conducting impulses and permitting 'communication' between neurons within the central nervous system).
