Understand the relationship between glial cells and brain tumors
The central nervous system (CNS) is composed of the brain and the spinal cord. The CNS collects information from the body and coordinates activity. The glial cell is considered as the most abundant cell type of the CNS. There are six types of glial cells, namely astrocytes, oligodendrocytes, ependymal cells, microglia, Schwann cells, and satellite cells.

Solved in 2 steps
- Can someone help explain the differences between glial cells and neurons in terms of their structure and function.Fill in the blanks: Neuroglial cells make up about ___________the mass of the brain and are about ___________ times ___________ abundant than neurons in the brain and spinal cord.List the distinguishing features of glial cells.
- Brain tumors are usually Glial Cell tumors? Do you know why? But first you must know what Glial cells are.Describe the role of neurotransmitters in the function of neurons.This is a biology question regarding nerve impulses. Neurofibromatosis type 1 is a condition where tumours can grow in the nerves near the skin. The growth of tumours prevents the action potentials from quickly travelling through the neurons. Identify the nerve structure from the image below and the division of the nervous system affected by neurofibromatosis type 1. CNS = Central Nervous System PNS = Peripheral Nervous System Select one: a. Nerve Structure Division of Nervous System 3 PNS b. Nerve Structure Division of Nervous System 4 CNS c. Nerve Structure Division of Nervous System 5 PNS d. Nerve Structure Division of Nervous System 1 CNS
- Please help me match the glial cell types to their functions.Schwann cells are a type of glial cell found in the nervous system. In addition to the conduction of nerve impulses, the outermost layer called neurilemma aids in nerve development and regeneration. Which of the following explains why the neurons in the brain cannot repair damage like the neurons in your hands or feet can?Neurons contain ________, which can receive signals from other neurons. a. axons b. mitochondria c. dendrites d. Golgibodies
- Match the neuron structure with its correct function or description. 1. Structure that receives stimuli and carries impulses to the cell body Grey matter 2. Part of the neuron that releases a chemical transmitter across the synapse + Myelin sheath 3. Cells that protect, nourish, and defend neurons + White matter 4. Structure that contains the neuron's nucleus and is the site of the neuron's cell metabolism : Synapse 5. The gap between two myelin sheaths that allows faster conduction of action potential 6. Lipid, fatty insulating layer around some axons that protects the neurons and speeds the impulses along the neuron + Dendrite 7. Unmyelinated neurons in the CNS + Axon 8. Structure that transmits impulses away from the cell body to another neuron, the muscles, or glands Axon terminal 9. Myelinated neurons in the CNS Cell body 10. The gap or junction between two neurons or between a neuron and a muscle Node of Ranvier * Glial cellExplain the relevance of neuroglia to the regeneration of damaged nerve fibers?Which of the following is not true of glial cells? They are more numerous than neurons. They transmit information. They have diverse functions in support of neurons. They can be a cause of brain tumors.
