Common positions include supine, lithotomy, lateral, prone and sitting.

Types of Patient Positions There are many different patient positions that medical professionals use. These include Supine, Prone, Lateral, Fowler's, Lithotomy, Trendelenburg, Reverse Trendelenburg, and Sims'. Each position has various benefits depending on the type of procedure and the needs of the patient.

The movement of the Earth around the Sun is its revolution. The Earth takes 365 days and 6 hours to complete revolution around the Sun. Therefore, it can be said that the Earth takes one year to make a complete revolution around the Sun. Thus, the Earth's revolution is also known as its annual movement.

After centuries of research, we currently know that the Earth isn't really flat, but rather an oblate spheroid. It is nearly flat at the poles and round at the sides. It is somewhat elliptical although generally round. That is how it transforms into an oblate spheroid.

Patient positioning involves properly maintaining a patient's neutral body alignment by preventing hyperextension and extreme lateral rotation to prevent complications of immobility and injury. Positioning patients is an essential aspect of nursing practice and a responsibility of the registered nurse.

Latitudes are all the parallel circles that line up to the poles, whereas Longitudes are the lines of reference that travel from the North Pole to the South Pole. They are both measured in degrees.

Rotation: When the planet earth spins on its axis, it is called rotation. It rotates counterclockwise or west to east when viewed from the North Pole. Revolution: When the planet earth moves around the Sun in a fixed orbit or path, it is called revolution. At this time, the earth is also performing a rotation.

Answer-On 21st March and September 23, direct rays of the sun fall on the equator. At this position, neither of the poles is tilted towards the sun: so, the whole Earth experiences equal days and equal nights. This is called an equinox.
