Question

Discuss the concept of the S.A.I.D. principle as it relates to

use and disuse of all excitable tissues. In your response, be sure
to indicate the importance of plasticity for neurons and muscles.

Answer 1

The S.A.I.D. principle explains how the body adapts to different types of physical activity or exercise. It applies to all excitable tissues and involves plasticity, which allows neurons and muscles to change and adapt in response to stimuli or demands.

Step-by-step explanation:

The S.A.I.D. principle stands for Specific Adaptation to Imposed Demands. It is a concept that explains how the body responds and adapts to different types of physical activity or exercise. According to this principle, the body will adapt to the specific demands placed on it, whether that is by increasing muscle strength, improving endurance, or enhancing skill-related aspects. This principle applies to all excitable tissues, including neurons and muscles.

Plasticity is a key aspect of the S.A.I.D. principle for both neurons and muscles. Plasticity refers to the ability of neurons and muscles to change and adapt in response to stimuli or demands. In the case of neurons, plasticity is crucial for learning and memory, as well as for recovery after injury. For muscles, plasticity allows them to grow stronger and more efficient in response to exercise or physical training.
