I believe its the very last one or the very 1st one. sorry I could only give a 50/50 answer:/
Answer:
The correct answer to fill in the blank is: glial cells.
Explanation:
<u>Glial cells are the other type of cells aside from neurons that are present in the nervous system. </u>
Glial cells are present both in the Central Nervous System and the Peripheral Nervous System, but in each of these anatomical divisions, the glial cells differ. For example, in the <u>Central Nervous System</u> there are oligodendrocytes (form myelin), astrocytes (provides nutrition for the neurons, maintains the ionic balance, repairs the tissue after damage, and forms the blood-brain barrier), ependymal cells (produces cerebrospinal fluid), and microglia (a specialized macrophage); while in the <u>Peripheral Nervous System</u> there are only Schwann cells (form myelin) and satellite cells (provide nutrients for the neurons).
The type of lipid formed from rings of carbon atoms which regulate sexual function, blood glucose levels and are an important component in <u>cell membranes</u> are known as Steroids.
Steroids- A steroid is an organic molecule having four rings organized in a certain chemical configuration that is physiologically active. The two main biological roles of steroids are as signaling molecules and as critical elements of cell membranes that affect membrane fluidity.
Cell Membrane- All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. The movement of materials into and out of the cell is controlled by the cell membrane.
