The sciatic nerve is a combination of common fibular and tibial. 

The sciatic nerve divides into its two branches::

1. The tibial nerve

2. The common fibular nerve

at the popliteal fossa.

The tibial nerve, which travels down the posterior compartment of the leg into the foot.

The common peroneal nerve also called the common fibular nerve, which travels down the anterior and lateral compartments of the leg into the foot.

23 chromosomes are in a human gamete.

Human somatic cells have 46 chromosomes(23 pairs) but a gamete(germ cell) gets half the amount, i.e. 23 chromosomes, (one from each pair). There will be half the number of chromosomes an organism has in its somatic cells (all other body cells except gametes).

For example in humans, the somatic cells contain 46 chromosomes which are the diploid number (2n) and each sperm and egg has 23 chromosomes where one of them is the sex chromosome.

The four most common soil erosion prevention methods are vegetation, geotextiles, mulch, and retaining walls.

By planting grass in areas of concentrated water flow, farmers can prevent much of the soil erosion that results from runoff, as the grass stabilizes the soil while still providing an outlet for drainage.

Preventing soil erosion is critical in protecting your property and exposed soil, whether from wind, weather, running water, and even the after-effects of the forest fire.

A transformer that increases voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a Step-Up Transformer.

Conversely, a transformer designed to do just the opposite is called a Step-Down Transformer. 

Every object has two typea of energies. They are ::

Potential energy

Kinetic energy

If the object is in motion, then it has Kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object.

Hence, another name for energy of motion is called Kinetic energy.
