What is Piloerection? Piloerection refers to a reaction of the sympathetic nervous system that causes certain muscles to contract and hair follicles to protrude outwards from the skin. Commonly called goosebumps or gooseflesh, it is a physiological response to cold air and intense emotions, especially fear.

- Goosebumps are another name for piloerection. Goosebumps may appear as a result of sudden fear or stress. Piloerection makes the hairs on a cat's back and tail stand on end, presenting them with a larger appearance for threatening predators. Piloerection offers protection to animals who are exposed to cold weather. Piloerection can occur in people when they get a chill.

Deforestation Deforestation, clearance, or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. Examples of deforestation include conversion of forestland to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests.

Rarefaction Rarefaction is the reduction of an item's density, the opposite of compression. Like compression, which can travel in waves, rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave. Rarefaction waves expand with time; in most cases rarefaction waves keep the same overall profile at all times throughout the wave's movement: it is a self-similar expansion. Each part of the wave travels at the local speed of sound, in the local m

Definitions &Translations Syringomyelia (/sɪˌrɪŋɡəmaɪˈiːliə, -ɡoʊ-/) is a generic term referring to a disorder in which a cyst or cavity forms within the spinal cord. This cyst, called a syrinx, can expand and elongate over time, destroying the spinal cord. The damage may result in loss of pain, paralysis, weakness, and stiffness in the back, shoulders, and extremities.

- However instead of crests and troughs, longitudinal waves have compressions and rarefactions. Definition 1: Compression. A compression is a region in a longitudinal wave where the particles are closest together. A rarefaction is a region in a longitudinal wave where the particles are furthest apart. As seen in Figure 1, there are regions where the medium is compressed and other regions where the medium is spread out in a longitudinal wave. The region where the medium is compressed is known as a compression and the region where the medium is spread out is known as a rarefaction.

Syringomyelia Syringomyelia is a rare disorder in which a cyst forms within your spinal cord. As this fluid-filled cyst, or syrinx, expands and lengthens over time, it compresses and damages part of your spinal cord from its center outward. People with the disorder might lose the ability to feel cold and pain normally.

Syrinx (medicine) In the case of syringomyelia, the syrinx can expand and elongate over time, destroying the spinal cord. Since the spinal cord connects the brain to nerves in the extremities, this damage may result in pain, weakness, and stiffness in the back, shoulders, arms, or legs. syrinx results when a watery, protective substance known as cerebrospinal fluid, that normally flows around the spinal cord and brain, transporting nutrients and waste products, collects in a small area of the spinal cord and forms a pseudocyst.

Rarefaction An example of rarefaction is as a phase in a sound wave or phonon. Half of a sound wave is made up of the compression of the medium, and the other half is the decompression or rarefaction of the medium. Rarefaction is the reduction of an item's density, the opposite of compression. Like compression, which can travel in waves (sound waves, for instance), rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave (see picture).

Girdling Girdling in Lille, Northern France. Girdling, also called ring barking or ring-barking is the complete removal of a strip of bark (consisting of cork cambium, phloem, cambium and sometimes going into the xylem) from around the entire circumference of either a branch or trunk of a woody plant.irdling is also used as a technique to force a fruit-bearing plant to bear larger fruit. A farmer would place a girdle (bark removal) at base of a large branch or at the trunk. Thus, all sugars manufactured by the leaves have no sinks but the fruit, which grows to above the normal size.
