Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How do glial cells help the brain function?
A
They release hormones into the blood.
B
They gather information.
C
They send and receive electrical signals.
D
They protect and support neurons.
Explanation: 

Detailed explanation-1: -Glial cells are the “glue” of the nervous system, engaging in many activities to support typical brain function. They do this by facilitating communication between neurons, regulating inflammation and forming the blood-brain barrier.

Detailed explanation-2: -Glial cells protect neurons against oxidative stress via transcriptional up-regulation of the glutathione synthesis.

Detailed explanation-3: -The nervous system consists of neurons and glial cells. Neurons generate and propagate electrical and chemical signals, whereas glia function mainly to modulate neuron function and signaling.

Detailed explanation-4: -Glial (Neuroglial) cells do not conduct nerve impulses, but, instead, support, nourish, and protect the neurons. Glial cells are far more numerous than neurons and, unlike neurons, are capable of mitosis.

Detailed explanation-5: -Glial cells support the function of neurons in the nervous system. They provide structural support and insulation for neurons, help maintain a healthy blood supply within the brain, and function as immunological sentinels. There are many different types of glial cells, each with its own definition and function.
