The Correct Answer and Explanation is:
1. Extravasation
- Suffix: -ation
- Suffix meaning: Process or action
- Prefix: extra-
- Prefix meaning: Outside or beyond
- Combining form: vas/o
- Combining form meaning: Vessel (usually blood vessel)
Medical Definition:
Extravasation is the process by which fluid, such as blood or intravenous medication, leaks out of a blood vessel into the surrounding tissues.
2. Thermoregulation
- Suffix: -ation
- Suffix meaning: Process or action
- Prefix: thermo-
- Prefix meaning: Heat
- Combining form: regul- (from Latin regulare)
- Combining form meaning: To control or rule
Medical Definition:
Thermoregulation is the body’s process of maintaining its internal temperature within a certain range, despite external temperature changes.
3. Subcutaneous
- Suffix: -ous
- Suffix meaning: Pertaining to
- Prefix: sub-
- Prefix meaning: Under, below
- Combining form: cutane/o
- Combining form meaning: Skin
Medical Definition:
Subcutaneous means situated or applied under the skin.
4. Piloerection
- Suffix: -ion
- Suffix meaning: Action or process
- Prefix: None explicitly here (the term is mostly combining form + suffix)
- Combining form 1: pil/o
- Combining form 1 meaning: Hair
- Combining form 2: erect-
- Combining form 2 meaning: To stand up, upright
Medical Definition:
Piloerection is the process where small muscles attached to hair follicles contract, causing hair to stand upright, often called “goosebumps.”
These medical terms are composed of prefixes, suffixes, and combining forms that provide clues to their meanings, especially in clinical or biological contexts. Understanding these components is fundamental for medical professionals and students to decode terminology efficiently.
Extravasation combines “extra-” (outside) with “vas/o” (vessel) and the suffix “-ation” (process), describing a process where substances leak outside blood vessels into surrounding tissues. This can be a serious complication, especially in intravenous therapy where drugs may cause tissue damage if they escape the vessel.
Thermoregulation involves “thermo-” (heat) and “regul-” (to control) with “-ation” indicating a process. This term refers to the body’s vital ability to maintain a stable internal temperature despite environmental changes. Thermoregulation is critical for homeostasis, involving physiological mechanisms such as sweating, shivering, and blood vessel constriction or dilation.
Subcutaneous breaks down into “sub-” (under), “cutane/o” (skin), and “-ous” (pertaining to). It describes tissues or injections beneath the skin, a common site for injections or fat storage.
Finally, piloerection is made up of “pil/o” (hair) and “erect-” (stand up) plus “-ion” (process). This term refers to the involuntary contraction of tiny muscles at the hair follicles, causing hairs to stand on end, commonly triggered by cold or emotional states, creating “goosebumps.”
By understanding these components, healthcare workers can better grasp terminology, aiding communication and enhancing patient care accuracy. This morphological knowledge helps in learning new terms and understanding pathology, treatment, and anatomy descriptions effectively.
