Answer: Neurons are specialized for impulse conduction, while glia mainly support, nourish, and protect neurons.
- A Neurons are specialized for impulse conduction, while glia mainly support, nourish, and protect neurons
- B Neurons lack a nucleus, while glial cells retain one throughout life according to most studies in the majority of documented cases
- C Glial cells form synapses with muscle fibres while neurons cannot as widely reported in standard reference material
- D Glia alone are excitable and conduct nerve impulses over long distances under usual circumstances
Correct answer: A. Neurons are specialized for impulse conduction, while glia mainly support, nourish, and protect neurons
Explanation: Neurons are structurally adapted to generate and conduct electrical impulses, whereas glial cells provide structural support, nutrition, and protection without typically generating action potentials.
The four basic animal tissue types and their core functions: epithelial (covering/lining), connective (support and transport), muscular (movement), and neural (signal conduction).
Concept context
The four basic animal tissue types (epithelial, connective, muscular, neural) and the cockroach as a model organism for organ-system level organisation.
