Which of the following cellular components is NOT present in cells that exhibit Nissl's granules and do not possess rough endoplasmic reticulum (RER) and ribosomes?
Neuroglial cells
Cells of the neural system that respond to stimuli
Dendrites of neurons
Cell bodies of excitable cells of neural tissue
Option 1 states that Neuroglial cells do not possess Nissl's granules and lack RER and Ribosomes. Neuroglial cells are a type of supportive cells in the nervous system that provide structural and functional support to neurons. Unlike neurons, they do not exhibit Nissl's granules, which are clusters of RER and ribosomes involved in protein synthesis. Neuroglial cells have different functions, such as insulation, nourishment and immune defense in the nervous system. Therefore, option 1 correctly identifies that neuroglial cells do not possess Nissl's granules and lack RER and ribosomes.
