frontális

Frontális is a Hungarian adjective meaning related to the front or anterior. It is used in several scientific contexts, most notably in anatomy, neurology, and descriptive geometry. The term derives from Latin frontalis, meaning “of the forehead” or “facing forward.”

In anatomy, frontális csont refers to the frontal bone, the bone that forms the forehead and the anterior portion of the skull. The frontal bone contributes to the orbits and protects the brain. It comprises parts such as the squama frontalis (the vertical forehead area) and the orbital part. It articulates with several neighboring bones, including the nasal, lacrimal, zygomatic, maxilla, and parietal bones.

In neuroanatomy, frontális lebeny refers to the frontal lobe, a major brain region involved in voluntary movement, planning and decision making, language production, and higher cognitive functions. The frontal lobe contains the motor cortex in the precentral gyrus and the prefrontal cortex, among other areas. Lesions in this region can affect movement, personality, and executive function.

In descriptive geometry and medical imaging, frontális sík denotes the frontal plane, an anatomical plane that divides the body into anterior and posterior parts. This plane is used to describe orientation in imaging modalities such as CT and MRI. In some terminology, it is also referred to as the coronal plane, depending on regional conventions.

Etymologically, frontális comes from Latin and reflects the concept of the front or anterior aspect. It is used across medical and scientific disciplines to indicate position, structure, or function related to the front part of the body.
