The thought is that a single neuron type should perform the same function, or suite of functions, within the brain. ... A multipolar neuron is a type of neuron that possesses a single axon and many dendrites. The insect nervous system is more complex, but also fairly decentralized. Glia guide developing neurons to their destinations, buffer ions and chemicals that would otherwise harm neurons, and provide myelin sheaths around axons. The nervous system of the common laboratory fly, Drosophila melanogaster, contains around 100,000 neurons, the same number as a lobster. One interesting difference between the nervous systems of invertebrates and vertebrates is that the nerve cords of many invertebrates are located ventrally (near the abdomen), whereas the vertebrate spinal cords are located dorsally (near the back). Microglia scavenge pathogens and dead cells. Solidify your knowledge of nervous system anatomy with these interactive quizzes and labeling exercises. asked Dec 6, 2018 in Biology by alam905 (91.0k points) Draw a neat labelled diagram of multipolar myelinated neuron. Parts of the nervous system are involved in determining how hard to push off and when to turn, as well as controlling the muscles throughout the body that make this complicated movement possible without knocking the bar down; all in just a few seconds. The nervous system coordinates the voluntary and involuntary actions of the body by transmitting signals from the brain to the other body parts and listening for feedback. Neuron Cell Body (Structure and Functions); explained beautifully in an illustrated and interactive way. Even fundamental functions, like breathing and regulation of body temperature, are controlled by the nervous system. 3. There is debate among evolutionary biologists as to whether these different nervous system plans evolved separately or whether the invertebrate body plan arrangement somehow “flipped” during the evolution of vertebrates. Pseudounipolar cells share characteristics with both unipolar and bipolar cells. Whereas, the motor neurons transmit information from the brain to the muscles. This is the currently selected item. Dendrites are the tree-like structures in neurons that extend away from the cell body to receive messages from other neurons at synapses; not all neurons have dendrites. Most neurons share the same cellular components. Pseudounipolar Neuron. Oligodendrocytes form myelin sheaths around axons in the CNS; Schwann cell forms myelin sheaths around axons in the PNS.

Dendrites are tree-like structures that extend away from the cell body to receive messages from other neurons at specialized junctions called synapses. There are also two other types of neurons- Pseudo-unipolar neuron and non-polar neuron. These neurons are not found in vertebrates, but are found in insects where they stimulate muscles or glands. Multipolar neurons are defined as having three or more processes that extend out from the cell body. Radial glia serve as bridges for developing neurons as they migrate to their end destinations. A neuron varies in shape and size depending upon their function and location. The PNS consists mainly of nerves, which are long fibers that connect the CNS to every other part of the body.

They are multipolar in structure. Axons are tube-like structures that send signals to other neurons, muscles, or organs; not all neurons have axons. They comprise of more than 99% of the neurons in humans, and are the major neuron type found in the CNS and the efferent division of the PNS. This is the most common type of neuron and transmits information from the brain to the muscles of the body. These terminals, in turn, synapse on other neurons, muscles, or target organs.
