Articular process is a bony projection on a vertebra (a spinal bone). It helps form the facet joints, which guide and limit spine motion. Clinicians use the term when describing anatomy on imaging, injury patterns, and arthritis. It also comes up when planning or targeting spine procedures around the facet joints.

Pericardium is the thin, sac-like structure that surrounds the heart and the roots of the great vessels. In plain terms, it is the heart’s outer “protective covering,” with a small amount of lubricating fluid inside. It is commonly referenced in cardiology when evaluating chest pain, shortness of breath, or fluid around the heart. It is also discussed in cardiothoracic surgery because pericardial tissue can be used for repairs or prosthetic devices.

Pars interarticularis is a small bony segment of a vertebra in the spine. It sits between key joints of the vertebra and helps transmit forces during movement. Clinicians often discuss Pars interarticularis when evaluating back pain, spinal stability, and stress fractures. It is also used as an anatomical landmark in imaging reports and surgical planning.

Lamina is a bony plate that forms part of the back wall of each vertebra in the spine. It helps create the spinal canal that protects the spinal cord and nerve roots. Lamina is commonly discussed in spine imaging reports and in surgeries such as laminectomy or laminoplasty. It is also relevant in fractures, tumors, infections, and degenerative narrowing of the spinal canal.

Epicardium is the thin outer layer of the heart wall. It lies directly on the heart muscle (myocardium) and is also called the visceral layer of the pericardium. Epicardium helps provide a smooth, low-friction surface as the heart beats. Clinicians commonly reference the Epicardium in imaging, heart surgery, and certain rhythm procedures.

Endocardium is the thin inner lining of the heart. It covers the heart chambers and helps form the surface of the heart valves. It is discussed in cardiology when describing heart structure, imaging findings, and several heart diseases. It is also a reference point for some catheter-based procedures performed inside the heart.

A Pedicle is a short, strong bridge of bone in each vertebra. It connects the front part of the vertebra (the vertebral body) to the back parts (the lamina, facets, and spinous process). In spine care, the Pedicle is important for stability and as a pathway for surgical screws. It is also used as an anatomical landmark on spine imaging.

The **Transverse process** is a bony projection that extends from the right and left sides of each vertebra. It helps form the shape of the spine and provides attachment points for muscles and ligaments. Clinicians commonly reference it on imaging studies like X-rays, CT, and MRI. It is also an important landmark in certain spine procedures and in evaluating spine injuries.

Myocardium is the muscular layer of the heart wall. It is the tissue that contracts to pump blood to the lungs and the rest of the body. Clinicians use the term Myocardium when describing heart function, heart injury, and heart muscle diseases. It is commonly discussed in cardiology visits, imaging reports, and hospital care for chest pain or heart failure.

Spinous process means the bony “bump” you can often feel along the midline of your back or neck. It is a projection from each vertebra (spinal bone) that sticks backward. Clinicians use it as a surface landmark during exams, imaging interpretation, and spine procedures. It also serves as an attachment point for important muscles and ligaments that help control spinal motion.
