What are the differences between internal and external shoulder rotation and how do they affect shoulder movement and function?
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.

What is internal movement of goods within logistics in a supply chain?
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.
What are differences shrimp and starfish?
Crayfish have an external skeleton and starfish have an internal skeleton relying on a water vascular system for movement.
What internal and external factors that could cause difficulty in movement?
Internal factors that can cause difficulty in movement include muscle weakness, joint stiffness, neurological disorders, and chronic pain. External factors may involve environmental barriers such as uneven surfaces, lack of accessibility in public spaces, or adverse weather conditions. Together, these factors can significantly impair mobility and overall physical function. Addressing both internal and external challenges is essential for improving movement and enhancing quality of life.
Do nematodes have external or internal shell?
Nematodes do not have a traditional shell like some other organisms; instead, they possess a tough outer cuticle that serves a similar protective function. This cuticle is external and is shed periodically as the nematode grows, a process known as ecdysis. Unlike mollusks, which have external or internal shells, the nematode's cuticle is flexible and allows for movement and growth.
Is a mountain formed by internal or external forces?
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.
Are earthquakes internal or external forces of change?
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.
What cell structure that allows cummunication between internal and external cell environment?
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.
Which ports has internal or external?
Ports can be classified as either internal or external based on their location and function. Internal ports are situated within a country's inland waterways, facilitating the movement of goods to and from inland areas, while external ports are located along coastlines or at sea, serving as entry and exit points for international shipping. Examples of internal ports include the Port of St. Louis on the Mississippi River, whereas external ports include major facilities like the Port of Los Angeles or the Port of Rotterdam. Both types of ports play crucial roles in global trade and transportation.
How does the nervous system regulate and coordinate the body's responses to external stimuli and internal changes?
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.
What are three internal and external physical forces that affect the earths surface?
Internal forces: tectonic plate movement, volcanic activity, and earthquakes. External forces: weathering, erosion by water/wind/ice, and impact events (e.g. meteorites).
What do living systems have that separates the internal chemicals from the external chemical environment?
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.
What is sports biomechanics?
•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.
