Consequently, several transverse sections are created to analyze or observe the organ anatomy.įor example, a large number of different transverse cuts of brain scan results, which show the anatomical structure. The section is made based on different heights or levels of a structure or an organ. Often, the transverse section tracks between the adjacent ends of a creature, from left to right. Most of the time it is mentioned the division is between the left and right. In the anatomic transverse plane, the view of the segmented portion might be two dimensional, the superior side of the inferior portion of the inferior side of the superior portionĪ transverse section divides the plane across the body of a plant, tissue, organ, or animal. In the transverse plane (which is also known as horizontal or axial) segmenting results in the superior and inferior portions. That plane crisscrosses the longitudinal axis at a 90-degree angle. Transverse Section DefinitionĪ transverse section is a cross-sectional part that is achieved by cutting the body or any part of the body structure in real or with help of imaging techniques in a horizontal plane. It proves helpful in understanding the mechanism of muscle action and movement i.e. The longitudinal section of skeletal muscle explains the organization and pattern of muscle fibers. The dissection at the longitudinal section will help in understanding the cellular and tissue level organization of an organism.

When the internal anatomical structures are compared with the fossil evidence, it helps to gain knowledge about evolutionary history.

Longitudinal section study also proves very helpful in the study of evolution. The nervous and digestive systems of elongated animals like snakes and worms can be studied easily through the longitudinal section. They are cut into different planes or sections accordingly for detailed view and research.įor a better understanding of structures and their physiology, the longitudinal view proves very useful and helpful. So the dissection is done on dead bodies. It is not possible to dissect the living animal or human transversely or longitudinally. The reason for the importance of the transverse and longitudinal planes is that they help to study the hidden organs and tissues of the body more openly and clearly. In the study of anatomical structures of plants and animals, the transverse and longitudinal sections are very important.

The plane that runs vertically is the longitudinal plane. It is also known as the horizontal plane.įigure 1: The different anatomical planes of the human body: coronal plane, transverse plane, and sagittal plane. Transverse Section: This plane divides the body into cranial and caudal parts, which means head and tail portion.It is also referred to as the frontal or coronal plane and it shows the coronal view. Coronal Section: This plane divides the body into dorsal and ventral or anterior-posterior parts.It is also named an anteroposterior or longitudinal plane. It splits the body to the right and left. Longitudinal section: This plane is parallel to the sagittal suture.
