Difference Between Mixed Cropping and Intercropping is that It is obvious that before focusing on relevant aspects that can be highlighted on this subject, a clear definition and difference between a neuron or nerve cell and glia or glial cells must be given.
First of all, say that both neuron and glia are the two types of cells that can be found in nerve tissue.
The neuron or nerve cell is considered as the basic unit of the brain, where we can find a large number of neurons (approximately 100,000,000,000), which communicate with each other through specific communications.
In a neuron we can distinguish several regions:
- The cellular body or Soma, which is the integrating center of information.
- Dendrites, which are small branches of the soma that act as signal receptors that come from other neurons.
- Axon, which is a long tubular extension that originates in a region of the soma, known as the Axonic Cone, where action potentials are generated.
- Presynaptic terminals, which are branches found in the axon and that contact the dendrites of another neuron.
The point of contact between neurons is called the Synapse so that the nerve cell that transmits the signal is called the Presynaptic Neuron, and the one that receives the signal, Presynaptic Neuron. The space left between neurons is called the Synaptic Cleft.
Depending on the morphology of the neurons, we can talk about Unipolar Neurons (they have a single extension that can be divided into many branches, and they lack dendrites), Bipolar Neurons (they have two extensions,
where there is a dendrite that carries the information to the soma, and an axon that conducts information from the soma to the CNS) and Multipolar Neurons (they have an axon and one or several dendrites).
Depending on the function, we can also talk about Sensory Neurons (they transmit information that comes from the sensory receptors to the CNS), Motor Neurons (transmit orders to the muscles) and Interneurons (they are the main part of the brain’s immense neural network,
existing within they Relay or Projection Cells, which carry information between separate regions of the brain, and Local Circuit Cells, which have short axons and process the information inside local circuits).
Gilas or glial cells are those units that are surrounding the cell bodies of neurons. There is a functional dependence between neurons and glial cells, in fact, Neuroglia plays a fundamental role during the development of the nervous system since they are the physical substrate for neuronal migration.
We can distinguish several life functions in the glands:
- They serve as a support element, thus providing structure and consistency to the brain
- They produce myelin, which is that insulating layer that covers many axons
- They collect and eliminate cell debris after injury or death of a neuron
- They maintain the concentration of potassium ions (K) in the extracellular fluid and capture neurotransmitters
- They serve as a guide for neuronal migration and axonal growth
- They participate in the formation of the blood-brain barrier, preventing the passage of toxic substances present in the bloodstream to the brain
- They are involved in some way in the nutrition of neurons
We also distinguish various types of glial such as Oligodendrocytes, which form the myelin sheath in the CNS by wrapping several axons at once, Schwann cells, which form the myelin sheath of the SNP by enveloping a single axon, Astrocytes,
which have starry bodies with long extensions surrounding the synapse region to capture the neurotransmitter and maintain the concentration of potassium ions, and Microglia, which are also starry but smaller cells that phagocytize the degenerated material?
I hope that all this basic information about the Difference Between Mixed Cropping and Intercropping will be of little help.
In the following post, we will talk about the process of synapses in neurons, and in what way the glial cells intervene.
