Step-by-step explanation:
The essential tools for the study of anatomy include observation, manipulation, auscultation, and palpation. Observation is the act of carefully looking at structures to gather information. Manipulation involves physically interacting with structures to understand their characteristics. Auscultation refers to listening to the sounds produced by certain body processes, such as using a stethoscope to listen to the heartbeat. Palpation involves feeling and touching structures to assess their texture, temperature, and other physical attributes.
