An LMS is the engine that powers eLearning, and in the most common form it consists of two separate parts: - A server component that performs the core functionality (creating, managing and delivering courses, authenticating users, serving data and notifications, etc.)
Atrophy vs dystrophy. What are atrophy and dystrophy? Atrophy and dystrophy are both terms related to muscular functioning. Muscular atrophy is wasting of muscles due to loss of tissue while muscular dystrophy is a group of muscle diseases that have weakness in the muscles and leads to reduced mobility. Muscular dystrophy causes debility and the person becomes progressively disabled as they lose the power of movement.
If enough cells in an organ atrophy the entire organ will decrease in size. Thymus atrophy during early human development (childhood) is an example of physiologic atrophy. Skeletal muscle atrophy is a common pathologic adaptation to skeletal muscle disuse (commonly called disuse atrophy).
