![]() The space between two Schwann’s cells is known as the nodes of Ranvier. The axon is covered with Schwann’s cells and the myelin sheath which is a protein sheath responsible for the protection of the Schwann’s cells. Longitudinal and transversal resistors are. 3.5: Part of a dendrite and the corresponding circuit diagram. The axon is a part which is elongated from the cell body till the end and the end of an axon is called an axon terminal. (3.13) is called the general cable equation. It consists of three major parts namely, Cell body, dendrites, Axon. The dendrites of spiny neurons radiate in all directions and are densely covered with spines (depicted somewhat realistically in A and iconically in B). Structure of nerve cell: axon, synapse, dendrite, myelin sheath, node Ranvier and Schwann cell. Dendrite is the part present at the front of the cell and it connects with the previous neuron and also the transfer of the signal is done at the axon and dendrite terminal of the neuron. The structure of neuron: Nerve cells or neurons are the structural and functional. spiny neuron cell body spiny dendrites axon presynaptic axon terminal spiny dendrites spiny neuron cell body A B FIGURE 1-5A and B Spiny neurons. Each of these parts have a specific function like the axon terminal is the end of the cell where it gets connected to the other neuron. Neuron consists of different parts which are axon, dendrite, nucleus, axon terminals. So, we see how a signal is conveyed to the brain by the chains of neurons. Summary Unipolar, multipolar, and bipolar neurons are all types of nerve cells that are responsible for transferring information throughout animal bodies. These neurons are connected to the receptors present in the body, so whenever the receptors get anything the message is conveyed to the neuron and then this neuron is connected in a chain formation with other neurons and connects to the brain. The neuron is the singular unit of the nervous system present in the human bodies. These axons and dendrite of a bipolar neuron locate at opposite poles of the neuron cell body. Bipolar neuron: The bipolar neuron possess only one dendrite and one axon. I hope the diagram might clarify the concepts of what the unipolar neuron looks like. ![]() ![]() (A) A robust, well-impregnated, normal HD neuron with an elaborate dendritic tree and. The photoreceptor cells of the retina (rod and cone cells) contain the unipolar neuron. The neurons are present throughout the body connected to each other. Rapid Golgi-impregnated neurons and dendritic branches. Also, the neuron is considered to be the largest cell of the human body. Hint: The neuron is a single cell which is known to transmit signals from one end to the brain or nervous system of the body. Dendrites are a collection of highly branched, tapering processes extending from the cell body (soma) of a neuron which conduct impulses toward the cell.
