Phrenic
Phrenic
Phrenic (pronounced: /ˈfrɛnɪk/) is a term derived from the Greek word phren, meaning mind or diaphragm. It is often used in medical terminology to refer to structures related to the diaphragm, the primary muscle involved in respiration.
Etymology
The term phrenic comes from the Ancient Greek word phrēn (φρήν), which originally referred to the mind or intellect. Over time, the term came to be associated with the diaphragm, a large, dome-shaped muscle located at the base of the lungs that plays a crucial role in breathing.
Related Terms
- Phrenic Nerve: This is a nerve that originates in the neck (C3-C5) and passes down between the lung and heart to reach the diaphragm. It is important for breathing, as it passes motor information to the diaphragm and receives sensory information from it. There are two phrenic nerves, a left and a right one.
- Phrenic Artery: This is a small artery that supplies blood to the diaphragm.
- Phrenicocolic Ligament: This is a fold of peritoneum (the membrane that lines the abdominal cavity) that extends from the splenic flexure of the colon to the diaphragm.
- Phrenology: This is a pseudoscience which involves the measurement of bumps on the skull to predict mental traits. It is based on the concept that the brain is the organ of the mind, and that certain brain areas have localized, specific functions or modules.
