Annulus fibrosus is the tough, fibrous outer ring of an intervertebral disc. It surrounds and contains the softer center of the disc (the nucleus pulposus). It helps the spine bear load, bend, and twist while protecting nearby nerves. Clinicians commonly discuss it when evaluating disc degeneration, annular tears, and disc herniation.
The Right Ventricle is one of the four chambers of the heart. It pumps oxygen-poor blood to the lungs through the pulmonary artery. Clinicians discuss it when evaluating shortness of breath, fluid retention, or pulmonary (lung blood vessel) conditions. It is commonly assessed on echocardiography, cardiac MRI, and sometimes heart catheterization.
The Left Ventricle is the heart’s main pumping chamber. It sends oxygen-rich blood to the entire body through the aorta. Clinicians discuss the Left Ventricle when evaluating symptoms like shortness of breath, chest discomfort, or fatigue. It is also a core focus of heart imaging tests such as echocardiography and cardiac MRI.
An Intervertebral disc is a soft, shock-absorbing structure between most of the bones (vertebrae) in the spine. It helps the spine move while spreading out forces from daily activities like sitting, bending, and lifting. Clinicians discuss the disc when evaluating neck and back pain, sciatica, and age-related spine changes. It is also central to many spine imaging reports and surgical planning conversations.
The Right Atrium is one of the four chambers of the heart. It receives blood returning to the heart from the body through the major veins. It helps move blood into the right ventricle and toward the lungs for oxygenation. Clinicians commonly reference the Right Atrium in imaging, rhythm evaluation, and catheter-based procedures.
A Luschka joint is a small joint in the lower neck between the sides of two neighboring vertebrae. It is also called an uncovertebral joint because it forms where the uncinate process meets the vertebra above. It is most commonly discussed in relation to cervical spine motion, arthritis, and nerve space narrowing. Clinicians often reference it when reading neck imaging or planning treatment for cervical radiculopathy.
The Uncovertebral joint is a small joint in the neck (cervical spine) formed between adjacent vertebrae. It sits along the outer (side) edge of the cervical intervertebral disc space. These joints help guide neck motion and contribute to stability. They are commonly discussed in cervical arthritis, nerve pinching, and neck imaging reports.
The Left Atrium is the upper left chamber of the heart. It receives oxygen-rich blood from the lungs and passes it to the left ventricle. Clinicians commonly reference the Left Atrium during heart ultrasound (echocardiography) and rhythm evaluation. It is also central in conditions like atrial fibrillation and mitral valve disease.
A Zygapophyseal joint is a small joint in the back of the spine where two vertebrae meet. It is also commonly called a “facet joint.” These joints help guide spinal motion and share load with the disc and other structures. They are frequently discussed in spine care because they can contribute to neck or back pain.
A Facet joint is a small joint in the back of the spine that connects one vertebra to the next. It helps guide and limit spinal motion while sharing load with the spinal disc. Facet joints exist in the neck (cervical), mid-back (thoracic), and low back (lumbar) regions. In clinical care, the Facet joint is often discussed when evaluating back or neck pain and stiffness.
