The answer: Ventricles.
There are four ventricles in the brain all connected between them,
where the cerebrospinal fluid is produced. There is a choroid plexus in each ventricle that produce the fluid.
The four ventricles:
<span><span>- 2 lateral ventricles right and left (one for each hemisphere)</span>
-third ventricle<span>
- fourth ventricle</span></span>
Smooth muscle<span> is composed of </span>involuntary muscles found<span> within the </span>walls<span> of </span>organs and structures such as the stomach, <span>esophagus, intestines, and </span>blood vessels. S<span>mooth </span>muscle<span> can never be under your control since they are involuntary. Cardiac </span>muscle<span> is also an </span>involuntary muscle<span>, </span>found only in the heart.

Answer:</h2>
Support cells of nervous system are collectively known as <u>neuroglia</u>.
<h2>
Explanation:</h2>
Neuroglia refers to a cell that has capacity to help neurons. In 1907, Italian scholar Emilio Lugaro proposed that neuroglia cells trade substances with extracellular liquid and along these lines apply control on neuronal condition.
It has since been demonstrated that glucose, amino acids, and particles-all of which impact neuronal capacity-are traded between the extracellular space and neuroglia cells. For example, after significant levels of neuronal action neuroglia cells can take up and spatially cradle potassium particles and in this manner keep up ordinary neuronal capacity.
