Two main types of cells compose the nervous system, namely, _____ and _____.
-
Glia and Nerve fiber
-
Neurons and Schwann Cells
-
Neurons and Glia
-
Microglia and Foot processes
Correct Answer
A. Neurons and GliaExplanation
The nervous system is composed of two main types of cells, neurons and glia. Neurons are responsible for transmitting electrical signals and information throughout the body, while glia provide support and protection for the neurons. This includes functions such as insulation, nutrient supply, and immune defense. Therefore, the correct answer is neurons and glia.Rate this question:

Look at the various types of glia cells and identify each of the following. What is number 4?
-
Oligodendrocyte
-
Axon
-
Neurons
-
Myelin
-
Microglia
-
Astrocyte
-
Synapses
Correct Answer
A. MyelinExplanation
Myelin is the correct answer for number 4. Myelin is a substance that forms a protective covering around nerve fibers, including axons. It is produced by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Myelin helps to insulate and speed up the transmission of electrical signals along the axons, allowing for efficient communication between neurons.Rate this question:

-
Oligodendrocyte
-
Axon
-
Neurons
-
Myelin
-
Microglia
-
Astrocyte
-
Synapses
Correct Answer
A. AstrocyteExplanation
Astrocytes are known as "the stars of the nervous system" because of their star-shaped appearance. They are a type of neuroglia that provide structural support to neurons and help regulate the chemical environment of the brain. Astrocytes also play a role in the formation and maintenance of synapses, the connections between neurons that allow for communication in the nervous system. They are involved in various important functions such as regulating blood flow, providing nutrients to neurons, and repairing damaged neural tissue.Rate this question:

Which type of glia cell is observed in the image? These cells are only found in the Peripheral Nervous System.
-
Astrocytes
-
Microglia
-
Ependymal Cells
-
Oligodendrocytes
-
Schwann Cells
Correct Answer
A. Schwann CellsExplanation
Schwann cells are a type of glia cell that is observed in the image. They are only found in the Peripheral Nervous System. Schwann cells play a crucial role in supporting and protecting neurons by forming the myelin sheath around nerve fibers. This insulation helps in the efficient conduction of nerve impulses. Schwann cells also aid in the regeneration of damaged nerves.Rate this question:

-
Oligodendrocyte
-
Axon
-
Neurons
-
Myelin
-
Microglia
-
Astrocyte
-
Synapses
Correct Answer
A. AstrocyteExplanation
Astrocytes are a type of glial cell found in the central nervous system. They are star-shaped cells that provide support and nourishment to neurons. They help regulate the chemical environment around neurons, maintain the blood-brain barrier, and play a role in synaptic transmission. Astrocytes also have important functions in repairing brain injuries and modulating neural activity. Therefore, astrocyte is the correct answer to number 6.Rate this question:

Where is this type of neuroglia cells located?
-
Autonomic Nervous System
-
Somatic Nervous System
-
Peripheral Nervous System
-
Neurotransmitter System
-
Visceral Sensory System
-
Central Nervous System
Correct Answer
A. Central Nervous SystemExplanation
Neuroglia cells are located in the Central Nervous System. The Central Nervous System consists of the brain and spinal cord. Neuroglia cells, also known as glial cells, are non-neuronal cells that provide support and protection to the neurons in the CNS. They play a crucial role in maintaining the structural integrity of the CNS and regulating the environment around the neurons.Rate this question:

Which type of neuroglia cell is seen in the electron transmission microphotograph?
-
Astrocyte
-
Microglia
-
Ependymal Cells
-
Oligodendrocytes
-
Schwann Cells
Correct Answer
A. MicrogliaExplanation
The correct answer is Microglia. Microglia are a type of neuroglia cell that are found in the central nervous system. They are the smallest and least numerous of the neuroglia cells and are responsible for immune defense and maintaining the health of neurons. In the electron transmission microphotograph, microglia can be identified based on their distinct morphology and characteristics. They have a small cell body with long, branching processes that extend outwards. This allows them to constantly survey the surrounding environment and respond to any signs of injury or infection.Rate this question:
