An anatomical plane is a hypothetical plane used to transect the body, in order to describe the location of structures or the direction of movements. In human and non-human anatomy, three principal planes are used: The sagittal plane or lateral plane (longitudinal, anteroposterior) is a plane parallel to the sagittal suture. It divides the body ...
Anatomical planes in a human. Anatomical terms describe structures with relation to four main anatomical planes: [2] The median plane, which divides the body into left and right. [2] [6] This passes through the head, spinal cord, navel, and, in many animals, the tail. [6] The sagittal planes, which are parallel to the median plane. [1]
Anatomical "lines", or "reference lines," are theoretical lines drawn through anatomical structures and are used to describe anatomical location. The following reference lines are identified in Terminologia Anatomica: Anterior median line; Lateral sternal line: A vertical line corresponding to the lateral margin of the sternum.
It is one of the planes which, combined with the umbilical plane, defines the four quadrants of the human abdomen. [4] The term parasagittal is used to describe any plane parallel or adjacent to a given sagittal plane. [5] Specific named parasagittal planes include: The midclavicular line crosses through the clavicle. Lateral sternal and ...
P: A Parasagittal plane (yellow) through one eye; parasagittal planes comprise the class of planes parallel to (and therefore lateral to) the sagittal plane. Standard anatomical planes and anatomical axes are used to describe structures in animals.
The three anatomical planes of the body: the sagittal, transverse (or horizontal), frontal planes. Anatomy is often described in planes, referring to two-dimensional sections of the body. A section is a two-dimensional surface of a three-dimensional structure that has been cut. A plane is an imaginary two-dimensional surface that passes through ...
Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision. Microscopic anatomy is the study of minute anatomical structures assisted with microscopes, and includes histology (the study of the organization of tissues), and cytology (the study of ...
It's the imaginary line that runs down from the point midway between the middle of the clavicle and the lateral end of the clavicle. The V 5 ECG lead is placed on the anterior axillary line, horizontally even with V 4. The midaxillary line is a coronal line on the torso between the anterior and posterior axillary lines.
