Pathology is exclusively defined as the study of patient symptoms during illness, neglecting its broader scope concerning disease mechanisms and causes.
Answer: False
Explanation: Pathology is fundamentally the study of disease, encompassing its causes, mechanisms, structural alterations, and clinical consequences, rather than being limited solely to the study of patient symptoms.
The term 'pathology' originates from the Ancient Greek words 'pathos,' signifying 'experience' or 'suffering,' and '-logia,' meaning 'study of.'
Answer: True
Explanation: The etymological origin of 'pathology' is from the Ancient Greek roots 'pathos' (experience/suffering) and '-logia' (study of), directly translating to the study of suffering or disease.
