Verified step by step guidance
1
Step 1: Understand the definitions of the terms provided in the question. Hypertonia refers to abnormally increased muscle tone or activity, Hypotonia refers to decreased muscle tone, Myasthenia refers to muscle weakness, and Atrophy refers to the wasting away or reduction in muscle size.
Step 2: Focus on the key phrase in the question: 'abnormally increased muscle function or activity.' This indicates that the term should describe heightened muscle tone or activity.
Step 3: Eliminate options that do not match the description. Hypotonia refers to decreased muscle tone, which is the opposite of what the question asks. Myasthenia refers to muscle weakness, which is unrelated to increased activity. Atrophy refers to muscle wasting, which also does not fit the description.
Step 4: Recognize that Hypertonia is the term that matches the description of abnormally increased muscle function or activity. It is characterized by excessive muscle tone, often leading to stiffness or difficulty in movement.
Step 5: Confirm your understanding by reviewing the definitions again and ensuring that Hypertonia is the correct term based on the context of the question.
