Final answer:
Hemimacroglossia is a condition where one lateral half of the tongue is enlarged, not shrunk, making the statement false.
Step-by-step explanation:
The term "hemimacroglossia" suggests an issue with the size of the tongue, specifically relating to one lateral half. However, the prefix 'hemi-' means half, 'macro-' generally denotes 'large', and 'glossia' pertains to the tongue. Therefore, hemimacroglossia refers to an enlargement of one half of the tongue, not the shrinking. Thus, the correct answer is:
B. False.
Beneath its mucous membrane covering, each half of the tongue is composed of the same number and type of intrinsic and extrinsic skeletal muscles, such as the longitudinalis inferior, longitudinalis superior, transversus linguae, and verticalis linguae. These muscles allow one to change the size and shape of the tongue which is important for functions such as swallowing and speech. The concept that one hemisphere is primarily responsible for language due to operations such as split-brain surgeries has contributed to understanding hemispheric functions, but does not relate directly to the terminology describing conditions of half the tongue.
