Which combining form pertains to the mind?

The combining form that pertains to the mind is "psych/o." This prefix is derived from the Greek word "psyche," which means soul or mind. It is commonly used in medical terminology to describe conditions, treatments, or studies related to mental processes, behaviors, and psychological conditions. For instance, terms like psychology (the study of the mind) and psychiatry (the medical specialty focused on diagnosing and treating mental health disorders) incorporate this combining form, emphasizing its direct connection to mental health and cognitive functions.

The other options, while also significant in medical terminology, refer to different areas: "neur/o" relates to nerves and the nervous system, "path/o" pertains to disease or suffering, and "emias" is associated with blood conditions. These terms highlight other medical fields but do not pertain specifically to the mind.
