The answer is the third one (C): Neurons, neuroglia.
Explanation for each option:
a. Axons, microtubules: This option is incorrect. Axons are part of neurons, specifically the long projections that transmit electrical impulses away from the neuron's cell body. Microtubules are structural components within cells, including neurons, but they are not cells themselves.
b. Cerebrospinal nerves, neuroglia: This option is incorrect. Cerebrospinal nerves is not a standard term used to describe cells in nervous tissue. Neuroglia, however, is correct as it refers to the supportive cells in nervous tissue.
c. Neurons, neuroglia: This option is correct. Neurons are the primary cells in nervous tissue that pass information through electrical and chemical signals. Neuroglia (or glial cells) are the supportive cells that provide structural and metabolic support to neurons.
d. Nuclei, dendrites: This option is incorrect. Nuclei are the central part of a cell containing genetic material, and dendrites are extensions of neurons that receive signals. Neither term refers to the types of cells in nervous tissue.
In summary, nervous tissue consists of neurons, which pass information, and neuroglia, which support them.
