10 Questions
Which of the following statements about bipolar neurons is correct?
They have two distinct processes: one dendritic process and one axon.
Which of the following statements accurately describes unipolar neurons?
The dendrites and axon are continuous, with the cell body off to one side.
What is the primary function of anaxonic neurons?
Their function is poorly understood, as their anatomy cannot distinguish dendrites from axons.
Which of the following statements about neuroglia is incorrect?
Neuroglia are larger than neurons but less numerous.
Which type of neuroglia is described as star-shaped, the largest and most numerous, forming a syncytium network?
Astrocytes
What is the primary function of neuroglia in the central nervous system (CNS)?
To provide physical structure, repair, phagocytosis, nutrient supply, and regulate interstitial fluid.
Which of the following statements about motor neurons is correct?
They control skeletal muscle movements and can be some of the longest neurons, extending from the spinal cord to toe muscles.
Which of the following statements about astrocytes is incorrect?
They are the smallest and least numerous type of neuroglia in the central nervous system (CNS).
What is the primary function of neuroglia in regulating the interstitial fluid in the neural tissue?
To maintain the proper ionic balance and concentration of neurotransmitters in the extracellular space.
Which type of neuron is responsible for relaying information from receptor cells to other neurons in special sense organs like sight, smell, and hearing?
