There is a question about neurons, how are neurons divided

The myelin sheath is important because it provides nutrients for the growth of neurons, and allows for more precise conduction of nerve impulses and a more defined path (imagine why the wire is covered with a wire jacket to prevent short circuits).

Mental activity cannot lead to changes in brain structure and function, because the human brain evolved from the ape's brain after tens of millions of years of evolution, and from this point of view, mental activity cannot lead to changes in brain structure and function; Of course, there should be small changes mentioned by LZ, but such small changes are negligible compared to the long-term evolution that has lasted tens of millions of years.

The protrusions of neurons are the extension of the cell body of neurons, which can be divided into dendrites and axons due to different morphological structures and functions. Dendrites are one or more protrusions that emanate from the body of the cell and are radial. Each neuron has only one cell body, and the cytoplasmic part of the axon is mostly cone-shaped, called the axon, in which there is no Nissl body, and there is mainly neurofibrillary distribution.

<> dendrites are short protrusions and axons are elongated.

And the direction of nerve excitatory conduction can only be from axon to dendrite, not reversed.

There are synaptosomes at the end of axons, but dendrites do not.

Dendrites have receptors that recognize neurotransmitters, but do not contain synaptic vesicles, that is, they cannot secrete neurotransmitters, that is, they can only accept and conduct impulses.

Axonal remorse is structurally much longer than dendrites, and its ends are enlarged into synaptosomes with a large number of synaptic vesicles that release neurotransmitters, which are bright but not recognize neurotransmitters (no receptors).

That is, impulses can only be transmitted by (the previous neuroid protrusion)-(dendrite)-(cell body)-(axon)-(synaptosome)-(next dendrite).

As for the endpoint, the endpoint of the dendrites is the axon terminal of another nerve staring cell, and the endpoint of the axon terminal is the dendrites of the next nerve cell.

Nerve cells are the bonding units and functional units of the nervous system of higher animals, also known as neurons. The basic function of neurons is to exchange information by receiving, integrating, conducting, and outputting information.

Nerve cells are the structural and functional units of the nervous system of higher animals, also known as neurons. The basic function of neurons is to exchange information by receiving, integrating, conducting, and outputting information. The brain is composed of neurons, and the neuronal population realizes the analysis function of the brain through the information exchange of each neuron, and then realizes the exchange output of samples.

The resulting sample illuminates the consciousness of the mound through the connection path.

1.Pseudomonopolar nerve amusement element:

The cell body is approximately round, emitting a protrusion that divides into two branches not far from the cell body, one dendrites are distributed to the **, muscles, or internal organs, and the other axon enters the spinal cord or brain.

2.Bipolar neurons:

The cell body is approximately spindle-shaped, with a dendrite and an axon, distributed in the retina and vestibular ganglia.

3.Multipolar neurons:

The cell body is polygonal, and the manuscript refers to Wang having an axon and many dendrites, which are the most widely distributed, and the neurons of the brain and gray matter of the spinal cord are generally of this type.

Cranial neurons are also known as cranial nerve cells. The basic structures include: cell body, nucleus, dendrite, axon. Neuronal cells connect with each other through synapses to transmit information. Neurons are the basic structural units of the nervous system.

Cranial nerves are also known as "cranial nerves". Paired nerves on the left and right emanate from the brain. There are 12 pairs in total, and their order is usually expressed in Roman order.

The olfactory nerve, optic nerve, oculomotor nerve, trochlear nerve, trigeminal nerve, abducens nerve, facial nerve, auditory nerve, glossopharyngeal nerve, vagus nerve, accessory nerve and hypoglossal nerve are sequentially followed, among which the trigeminal nerve is composed of ophthalmic nerve, maxillary nerve and mandibular nerve, respectively.

Agree with zjzop, but she is nothing is a neuron, neurons are the cell body of nerve cells, from the cell body send out the axons and dendrites of nerves, the axons receive the nerve impulses conducted by the dendrites of the superior nerve cells, the dendrites give out the nerve impulses of the cell, and the brain neuron is the cell body of the cranial nerves.

It is the cell body that gives out the cranial nerves. The relationship between brain neurons and cranial nerves is like that of a lake and a stream that flows from it.

Post-consciousness ** is a kind of intelligence specially made after infusing the biological information code of the human brain in the ordinary**, so as to decipher the "password" of the brain's higher logical thinking space. Through intelligent sound wave intervention, more neuronal cells can be connected to form new channels, prenatal education, early education, brain development, beauty and rejuvenation, stress reduction sleep, especially sexual health is exquisite!

Differences: 1. The composition is different.

Nerves: Constructed of highly differentiated cells.

Neurons: Made up of glial cells.

2. The formation method is different.

Nerves: Nerve fibers make up nerves.

Neurons: Nerve cells.

3. Different classifications.

Nerve:. Nerves are further divided into motor, sensory, and mixed nerves.

Neurons: classified by the number of neuron protrusions: unipolar neurons, bipolar neurons, multipolar neurons. Classified by neuron function: sensory neurons (afferent neurons), motor neurons (efferent neurons), liaison neurons (interneurons).

4. Different forms.

Nerves: They are made up of axons of motor nerves or long dendrites of sensory neurons (both collectively known as axonins) and glial cells that surround it.

Neurons: are made up of two parts: cell bodies and protrusions.

Neurons, also known as neural tissue, are the basic units that make up the structure and function of the nervous system. Neurons are cells with long protrusions, which are made up of cell bodies and cell protrusions.

Nerves: Nerve fibers are tissues that transmit excitation from the brain and spinal cord to the organs, or to the brain and spinal cord.

Neurons, also known as nerve cells, are the basic units that make up the structure and function of the nervous system.

Nerves are made up of bundles of nerve fibers.

Nerves are systems of neurons and mediators; Nerves are systems.

The reason why nerves are often used and systems are omitted is because nerves themselves are a system concept. According to the definition of physiological psychology, a nerve is a system composed of neurons, that is, the neuronal system. Among them, neurons are the basic functional structural units of the nervous system.
