Question

which of the following are functions of neuroglial cells? they conduct impulses to stimulate muscle contractions. they remove excess ions and neurotransmitters from areas surrounding neurons. they guide neurons into position during embryogenesis. they produce growth factors for neurons. they conduct impulses to stimulate glandular secretions.

Explanation:

Neuroglial cells support neurons. They clean up ions and neurotransmitters, help with neuron - placement during development, and provide growth factors. Conducting impulses for muscle contractions or glandular secretions is mainly a function of neurons, not neuroglial cells.

Answer:

• They remove excess ions and neurotransmitters from areas surrounding neurons.
• They guide neurons into position during embryogenesis.
• They produce growth factors for neurons.
