There are different types of receptors, which allow neurons to receive information. In nose you have chemoreceptors. In eyes you have photoreceptor. In the ears you have hair cells of different length, which resonates with sounds of different frequency. On the surface of the tongue you have again chemoreceptors. In the skin you have different types of receptors to give you information like heat, cold, pain, touch and vibration sense.

∙ 11y agoThe synapse is the space between the two communicating neurons, where the transmission of neurotransmitters takes place. It is very important, because it is like a bridge between the two neurons that are communicating. It is where the information is transmitted from one neuron to the next. In the presynaptic neuron there are neurotransmitters in vesicles (enclosed containers for storing the neurotransmitters). Just before one neuron communicates to the next the action potential reaches the presynaptic neuron's terminal, which activates ion channels to open. When these channels open calcium ions flood in. The calcium ions cause some of the vesicles containing neurotransmitters to fuse with the membrane. Then the neurotransmitters are released into the synapse. The neurotransmitters then fuse with the postsynaptic neuron onto chemical receptors that match their molecular shape, which causes ion channels in the postsynaptic neuron to open. When the calcium ions enter the postsynaptic neuron they set off a graded potential in the postsynaptic neuron. This starts the whole process of communication over in the next neuron so it can continue sending information along its path and to other neurons or cells. Therefore, the synapse is very important, because it helps the communication to pass from one neuron to the next and starts the process again in the receiving neuron.
Although the synapse serving as a bridge between the presynaptic and postsynaptic neurons is important, it certainly is not the only important function it has worth mentioning. It also slows down the process of communicating by a couple of milliseconds, which is a significant amount of time for the chemical transmission. We know that speed is very important in the communication of neurons; however, this slowing adds important complexities to the process of communication.

What is the structure of a neuron and its role in the brain?
A neuron has dendrites (as inputs), a cell body (soma), and an output (axon).The neuron is the functional unit of the brain: neurons receive sensory information, process that information, store it, and convey commands to muscles and glands based on that information and its processing.
What increases when there are convulsions in the cerebrum?
neuron cell bodies
What is A specialized that can receive and transmit signals to other cells like it called?
Neuron
What is the branching fiber that is the first part of the neuron to receive a nervous system impulse called?
The branching fiber that is the first part of the neuron to receive a nervous system impulse is called a dendrite. Dendrites receive signals from other neurons or sensory receptors and transmit these signals to the cell body of the neuron. They play a crucial role in receiving and integrating incoming information in the nervous system.
What carries impulses away from the cell body?
The axon carries information from one neuron to another while the dendrites of a neuron receive information from other neurons
The part of the neuron that has branched extensions that are specialized to receive information are the?
dendrites. Dendrites are specialized structures on a neuron that receive signals from other neurons and transmit them towards the cell body. They play a crucial role in integrating information from multiple sources to determine the neuron's response.
Which neuron receives information?
actually we must say all neurons receive information. there are three types of neurons: 1.sensory neuron 2.motor neuron 3.relay neuron the sensory neurons receive information from receptor cells in sense organs and pass the information from sensory neuron to the other and pass the info to spinal cord where they are received by relay neuron. this neuron in turn passes the info to motor neurons which pass the info to cells in effectors and action is performed.relay neurons are messengers between sensory neuron and motor neuron in spinal cord.
name the neuron structures that receive incoming information and the structures through which information exits (or is passed on) from the cell?
Dendrites

What neurons receive information from sensory organs?
Dendrites are the part of the neuron specialized to receive information from other neurons and the axon transmits signals to other neurons or to muscles or glands.
Can a neuron have multiple axons?
No, each neuron has only one axon, but has multiple dendrites so it can receive information from multiple axons from other multiple neurons.
Which part of the neuron transmits information to other cells?
The end of one neuron, the presynaptic button, sends messages to other cells by releasing neurotransmitters (chemical messengers) into the synaptic cleft (a small space between two neurons). The other cell, whether it be a neuron, a muscle, a sweat gland, etc., will receive this message at the post synaptic membrane of its cell, and will respond accordingly.
What increases when there are convulsions in the cerebrum?
neuron cell bodies
What is A specialized that can receive and transmit signals to other cells like it called?
Neuron
What portion of a neuron contains a bulk of cytoplasm?
the soma, or cell body, of a neuron contains a majority of the cytoplasm. the processes that receive information and those that transmit that information, dendrites and axons respectively, are much thinner and require much less machinery to serve their function.
The single long strand that comes out of the other side of the cell body is called the?
axon-kenyonthanks ya kenyon-lexi

They play a crucial role in receiving and integrating incoming information in the nervous system.
