Internal shoulder rotation involves the rotation of the shoulder joint inward towards the body, while external rotation involves the rotation of the shoulder joint outward away from the body. These movements are important for various shoulder functions such as reaching, lifting, and throwing. Internal rotation allows for activities like reaching behind the back, while external rotation is crucial for throwing motions and overhead movements. Imbalances in these rotations can lead to shoulder pain, limited range of motion, and decreased functional abilities. Strengthening and maintaining a balance between internal and external rotation is essential for optimal shoulder movement and function.
The internal movement of goods in a supply chain is the paperwork of the external movement of the goods. The external movement is bringing the supply from one place to the other. Internal movement is the tracking of supplies.
Crayfish have an external skeleton and starfish have an internal skeleton relying on a water vascular system for movement.
A mountain is formed by both internal and external forces. Internal forces, such as tectonic plate movement and volcanic activity, cause the uplift of the Earth's crust. External forces, such as erosion by wind, water, and ice, shape the mountain's surface over time.
Earthquakes are internal forces of change caused by tectonic plate movement and stress release along faults within the Earth's crust. They are not considered external forces as they originate from within the Earth.
The cell membrane is the structure that allows communication between the internal and external cell environment. It controls the movement of molecules in and out of the cell, helping to maintain homeostasis and respond to changes in the cell's surroundings.
The nervous system controls the body's reactions to outside stimuli and internal changes by sending electrical signals through neurons. These signals help coordinate actions like movement, sensation, and organ function.
Internal forces: tectonic plate movement, volcanic activity, and earthquakes. External forces: weathering, erosion by water/wind/ice, and impact events (e.g. meteorites).
Living systems have cell membranes that separate internal chemicals from the external chemical environment. These membranes control the movement of substances in and out of the cell, allowing for selective exchange of molecules and maintaining internal conditions necessary for life.
•Sports biomechanics is the science that deals with an athletes movement whilst also considering the internal and external forces that are in effect whilst performing any desired movement.
An internal force is a force acted upon by an object to force another object's movement internally. An external force is a force exerted on an object based on the objects position and force applied on the object which causes the opposite forces change in motion.

Internal migration is movement within a country. For example, moving from the East Coast of the US to the West Coast.International migration is moving from one country to another. For example moving from China to America.
