Which is NOT a function of neuroglial cells? produce myelin send impulses structurally support neurons help nourish neurons

## Step 1<br />Neuroglial cells, also known as glial cells or simply glia, are non-neuronal cells in the central nervous system (brain and spinal cord) and the peripheral nervous system. They perform several critical functions to support neurons, the primary functional units of the nervous system.<br /><br />## Step 2<br />The functions of neuroglial cells include:<br />1. **Producing Myelin**: Some glial cells, such as oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system, produce myelin. Myelin is a fatty substance that wraps around axons, providing insulation and increasing the speed of electrical signal transmission.<br />2. **Structurally Supporting Neurons**: Glial cells provide structural support to neurons. They help maintain the shape and organization of the nervous system.<br />3. **Helping Nourish Neurons**: Glial cells supply nutrients to neurons and remove waste products. This is particularly important in the central nervous system, where neurons do not have direct access to blood vessels.<br /><br />## Step 3<br />However, sending impulses is not a function of neuroglial cells. This function is specific to neurons, which are the primary functional units of the nervous system responsible for transmitting electrical signals.
