3. Glial cells are specialized cells that support nerve cells in addition to neurons.
4. Glial cells support, nourish, insulate, and eliminate metabolic waste products from neurons.

Explanation of the incorrect options:

Option A:

1. Glial cells in nerve tissue have more functions than only providing support.
2. It had no effect on impulse control.

Option B:

1. Glial cells in nerve tissue serve more than nourishment function.
2. It won't help with impulse control.

Option D:

In nerve tissue, glial cells play no role in impulse transmission or multiplication.

Final answer: Glial cells in nervous tissue help in support and nourishment.
