What functional class of neuron is found completely within the CNS? Identify the CNS component from the given description: It includes the thalamus and hypothalamus. Identify the term: Cells in the CNS that form myelin. What does the oculomotor nerve do in the body?
<p><strong>Step-by-Step Solution:</strong></p><p>1. <strong>Definition of Saltatory Conduction</strong>: - Saltatory conduction refers to the process by which nerve impulses jump from one node of Ranvier to another along myelinated axons. The myelin
The neurons are long cells that have a cell body, that has a nucleus and most cytoplasm, dendrites that are short extensions and axons that are long extensions with myelin sheath secreted by Schwan cells. Myelin sheath is not continuous but interrupted in between to have a node of Ranvier. ...
Why is the Node of Ranvier important? What is the importance of organic chemistry? Why are superconductors important? Why are cilia important? Why is copper important? Explain the properties of cotton fiber considered by cotton spinners.
1. What is the major function of the neuron? 2. Are the nodes of Ranvier spaced equally along the axon? Why is this significant? 3. Define depolarization. What is the conduction of a nerve impulse down the axon called? What is the function of neurotransmitters? ...
What do the Na+ and K+ do?Nodes of Ranvier:Periodic interruptions in the concentric insulating layer (myelin sheath) of the axolemma are known as the node of Ranvier. This was named after its discoverer Louis-Antoine Ranvier. He described them as constrictions.Answer and Explanation: ...
Which of the following is not a principal component of neurons? (a) Axon (b) Neuroglia (c) Cell body (d) Dendrite (e) Node of Ranvier. What is the name of the nervous tissue where the presynaptic parasympathetic nerves that serve ...
Dendrites are the signal receiving end of the neuron and axons are the signal transduction processes. Axons are surrounded by Schwann cells that produce lipoprotein material called myelin sheaths. Myelin sheath is not a continuous sheath but has gaps called node of Ranvier....
What part of a nerve cell carries signals toward the part of the cell that houses the nucleus? a. node of Ranvier b. axon c. cell body d. dendrite e. neuron Action Potentials: One of the main functions...
