<span>The answer would be: a) Frost-wedging happens when water freezes and breaks rocks.
Normally, the volume of a substance will become lower when the temperature drops but when water becomes ice it will expand. Water that freezes into ice can produce a high pressure from the expansion of their volume. If enough water fills a joint in a rock, the rock might get enough force to fractured or break. This will happens in the area that has a freeze-thaw cycle like in the polar climate.</span>

Spinal nerve divides into several branches after passing through its intervertebral foramen. These branches are called rami. A spinal nerve gives off several branches such as anterior ramus, posterior ramus, rami communicantes, and a meningeal branch. The meningeal branch reenters the vertebral cavity through the intervertebral foramen. It serves to supply the vertebrae, vertebral ligaments as well as the blood vessels of the spinal cord, and meninges.

Neuroglia<span>, which is sometimes referred to as "</span>glia", are cells that are not neurons but merely support and provide protection for neurons. They are called 'non-neuronal cells' and they exist<span> in the </span>central nervous system<span> (</span>brain<span> and </span>spinal cord<span>) and the </span>peripheral nervous system (nerves outside the brain and the spinal chord).
