Is there a diagram of the spine which labels all its sections?

Starting from the base of the brain and extending to the waist, the spinal cord measures around 18 inches. It is protected by vertebrae, which are rings of bone surrounding it.\nThere are 8 vertebrae in the neck, called the cervical vertebrae. They are named C1, C2 and so on. There are 12 vertebrae in the chest, called the thoracic vertebrae, also named T1, T2 and so on. There are 5 lumbar vertebrae (L1 to L5) and also 5 sacral vertebrae (S1 to S5).\nIn general, a person will experience more dysfunction the closer to the brain a spinal injury occurs.

What are Okazaki fragments?

DNA is double-stranded, consisting of two polymer strands that run antiparallel to each other. One strand runs in the five-prime to three-prime direction, while its complementary strand runs three-prime to five-prime. During DNA replication, the two strands separate a little at a time, and two new strands are synthesized using each original strand as a template. The moving area where the original DNA unravels is called a replication fork.\nBiologically and chemically, new DNA can be created only in the five-prime to three-prime direction, which complicates the replication process since the two..

How does an ice cube melt?

Within ice cubes, not all of the solid crystals are aligned precisely with one another. At these junctures, the atoms start to move, a trend that then spreads throughout the crystal, turning the parts that had orderly alignment into chaos as well, according to Live Science. The implication is that there may be liquids inside crystals that have not yet reached the melting point, but Live Science explains that further study is necessary to verify that claim.\nIce cubes tend to melt more quickly in water than if they are left out on a surface at room temperature, even if the water is slightly col..

What are some facts about forests?

Forests have three different layers: the forest floor, the canopy and the understory. Forest floors are home to many different types of animals and plants such as grasses and wildflowers. The floor itself consists of soil as well as the decomposing biomass created by dead plants and animals. The understory, also known as the shrub layer, contains small trees, bushes and shrubs. The leaves and branches of the trees make up the canopy, which is the tallest layer of the forest.\nTropical rain forests grow near and around the equator. These forests have the greatest species diversity of any biome...

Is biomass energy safe?

Biomass energy also has a lot of potential to do good. Low-carbon biomass can provide a significant fraction of the renewable energy needed to reduce emissions of heat-trapping gases such as carbon dioxide. So long as the biomass is produced sustainably, biomass energy can meet current energy needs while causing little to no harm and without diminishing resources.

What is the specific heat of silver?

The calculation formula for specific heat is derived from an equation that expresses the relationship between heat and temperature changes. The heat changes are equated to a product of mass of the material, heat capacity and changes in temperature. However, Georgia State University notes that this relationship does not apply when the material is changing from one state of matter to another because the amount of heat involved is greater than the specific heat.

Do fish need oxygen?

Fishes use their gills to get oxygen from the water in a way similar to the way humans use their lungs to get oxygen from the air. Air has 21 percent oxygen, while oxygen in water is a rare resource. Fish only need a tiny amount of dissolved oxygen. They are able to live well if the dissolved oxygen is at least five parts per million. If the dissolved oxygen is less than two parts per million, most fish will eventually suffocate and die.

What are the effects of an earthquake?

The amount of structural damage that can occur during an earthquake with a magnitude of 4.0 or higher depends on the construction of the structure. In California, many newer structures are specifically designed to withstand earthquakes, but some of the older buildings do not respond well to ground motions.\nEarthquakes are defined as an intense shaking of the ground that occurs when a fracture in the earth's rocks causes the ground to shift. Rock fractures are also referred to as faults, which is where the term fault line developed. Fault lines are the specific locations of each fault, an..

Where can one find calendar numbers to print?

Calendar themes at Preschool Printables include holidays, seasons and miscellaneous themes. Major holidays are included on the site, including Valentine's Day, St. Patrick's Day, 4th of July and Christmas. Winter, spring, summer and fall are represented with decorations such as snowflakes, butterflies, the sun and pumpkins. The miscellaneous collection includes themes suitable for children and school such as dinosaurs and graduation caps.

What is slab pull?

The tectonic plates that make up the Earth's crust are in constant motion. According to Columbia University, faults where subduction is occurring result in a force known as slab pull. This force is created as the plate begins to sink into the Earth's mantle and serves to pull the lower plate further away from the volcanic ridge where it is formed.
