A patient with a spinal cord injury has impaired transmission of nerve signals. Which supporting cell function is normally important for nervous tissue?
Correct answer: A. Supporting and insulating neurons
- A. Supporting and insulating neurons
- B. Producing antibodies in plasma
- C. Storing calcium in bone
- D. Contracting to move a joint
Explanation
Neuroglia support, protect, nourish, and in some cases insulate neurons, helping nervous tissue function properly. Antibody production is associated with immune cells, while bone storage and movement involve connective and muscular tissues.
