- When a reflex arc consists of only two neurons in an animal (one sensory neuron, and one motor neuron), it is defined as monosynaptic. Monosynaptic refers to the presence of a single chemical synapse.here are two types of reflex arc: autonomic reflex arc (affecting inner organs) and somatic reflex arc (affecting muscles).

Nonsynaptic plasticity Nonsynaptic plasticity is a form of neuroplasticity that involves modification of ion channel function in the axon, dendrites, and cell body that results in specific changes in the integration of excitatory postsynaptic potentials (EPSPs) and inhibitory postsynaptic potentials (IPSPs).

Neurons, Brain Chemistry, and Neurotransmission (Page 1 of 2) A neuron is a specialized cell that can produce different actions because of its precise connections with other neurons, sensory receptors, and muscle cells. A typical neuron has four morphologically defined regions: the cell body, dendrites, axons, and presynaptic, or axon, terminals.

Axon In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the electrical impulse travels along an axon from the periphery to the cell body, and from the cell body to the spinal cord along another branch of the same axon.n axon is one of two types of protoplasmic protrusions that extrude from the cell body of a neuron, the other type being dendrites.

Neuron A typical neuron consists of a cell body (soma), dendrites, and an axon.The term neurite is used to describe either a dendrite or an axon, particularly in its undifferentiated stage.f the voltage changes by a large enough amount, an all-or-none electrochemical pulse called an action potential is generated, which travels rapidly along the cell's axon, and activates synaptic connections with other cells when it arrives. Neurons do not undergo cell division.

Reflex Sensation Describe Monosynaptic reflex: When a reflex arc consists of only two neurons in an animal (one sensory neuron, and one motor neuron), it is defined as monosynaptic.Monosynaptic refers to the presence of a single chemical synapse.n polysynaptic reflex pathways, one or more interneurons connect afferent (sensory) and efferent (motor) signals. All but the most simple reflexes are polysynaptic, allowing processing or inhibition of polysynaptic reflexes within the spinal cord.

Neuroscience For Kids The Neuron. One way to classify neurons is by the number of extensions that extend from the neuron's cell body (soma). Bipolar neurons have two processes extending from the cell body (examples: retinal cells, olfactory epithelium cells). Pseudounipolar cells (example: dorsal root ganglion cells).

What is the difference between unipolar neurons and multipolar neurons? Answers. Best Answer: In a unipolar neuron, or pseudounipolar neuron, the dendrites and axon are continuous--basically, fused--and the cell body lies off to one side. In such a neuron, the initial segment lies where the dendrites converge.he rest of the process, which carries action potentials, is usually considered to be an axon. Most sensory neurons of the peripheral nervous system are unipolar. Their axons may extend a meter or more, ending at synapses in the central nervous system.

Neuron A typical neuron consists of a cell body (soma), dendrites, and an axon.n axon (also called a nerve fiber when myelinated) is a special cellular extension (process) that arises from the cell body at a site called the axon hillock and travels for a distance, as far as 1 meter in humans or even more in other species.

- General structural features of neurons are the perikarya, dendrites and axons. The stereotypical image of a neuron is that of a stellate cell body, the perikaryon or soma, with broad dendrites emerging from one pole and a fine axon emerging from the opposite pole.owever, this picture does not hold true for many neurons. The neuron is the most polymorphic cell in the body and defies formal classification on the basis of shape, location, function, fine structure or transmitter substance.

- At all the levels of the spinal cord, nerve cells in the gray substance are multipolar, varying much in their morphology. Many of them are Golgi type I and Golgi type II nerve cells. The axons of Golgi type I are long and pass out of the gray matter into the ventral spinal roots or the fiber tracts of the white matter.

Ch. 11 The Nervous System What are the anatomic and functional categories of neurons? a)unipolar neurons have a single process called the axon. During development, the dendrite fused with the axon. b) Bipolar neurons have 2 relatively equal fibers extending off the central cell body. c) Axaxonic CNS interneurons have no apparent axon.

Dendrite Pyramidal cells are multipolar cortical neurons with pyramid shaped cell bodies and large dendrites called apical dendrites that extend to the surface of the cortex. Bipolar neurons have one axon and one dendritic tree at opposing ends of the cell body.heir dendrites do not process electrical signals. Dendrites are one of two types of protoplasmic protrusions that extrude from the cell body of a neuron, the other type being an axon. Axons can be distinguished from dendrites by several features including shape, length, and function.

- A multipolar neuron (or multipolar neurone) is a type of neuron that possesses a single (usually long) axon and many dendrite s, allowing for the integration of a great deal of information from other neurons. These dendritic branches can also emerge from the nerve cell body.nswers: In vertebrates, the term motor neuron (or motoneuron) classically applies to neurons located in the central nervous system (CNS) that project their axons outside the CNS and directly or indirectly control muscles. Motor neuron is often synonymous with efferent neuron, primary neuron, or alpha motor neuron.

What is an Interneuron? An inter neuron is a multi polar neuron, or a neuron with one or more Dendrite. Dendrites are branched projections from the main body, or soma of the nerve cell. Dendrites usually receive information via electrochemical signals from the axon of another neuron, but they can also send out certain types of signals.

Functional Classification of Neurons â Diagrammatic View In comparison, motor neurons (efferent neurons; lower motor neurons) are multipolar shaped cells that conduct action potentials out of the central nervous system. Their cell bodies and dendrites are located in the central nervous system and their axons run inside the nerves to the peripheral organs.

Neuron A typical neuron consists of a cell body (soma), dendrites, and an axon. The term neurite is used to describe either a dendrite or an axon, particularly in its undifferentiated stage.he cell body of a neuron frequently gives rise to multiple dendrites, but never to more than one axon, although the axon may branch hundreds of times before it terminates. At the majority of synapses, signals are sent from the axon of one neuron to a dendrite of another.

What Are Nerve Cells? - Function, Types & Structure Bipolar neurons are nerve cells that have two projections and are used in specialized sense detection, such as in smell and sight. Multipolar neurons are nerve cells that have many cell extensions, including dendrites, which are receiving pathways, and typically one axon, which is a delivering pathway.
