Midsternal Line
The Midsternal line is used to describe a part of the surface anatomy of the anterior thorax. The midsternal line runs vertical down the middle of the sternum. It can be interpreted as a component of the median plane.

Surface Anatomy
Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal.Seeley (2003) chap.1 p.2 In birds this is termed ''topography''. Surface anatomy deals with anatomical features that can be studied by sight, without dissection. As such, it is a branch of gross anatomy, along with endoscopic and radiological anatomy.Standring (2008) ''Introduction'', ''Anatomical nomenclature'', p.2 Surface anatomy is a descriptive science. In particular, in the case of human surface anatomy, these are the form and proportions of the human body and the surface landmarks which correspond to deeper structures hidden from view, both in static pose and in motion. In addition, the science of surface anatomy includes the theories and systems of body proportions and related artistic canons. The study of surface anatomy is the basis for depicting the human body in classical art. Some pseudo-sciences such as physiognomy, phrenology and pa ...

Thorax
The thorax or chest is a part of the anatomy of humans, mammals, and other tetrapod animals located between the neck and the abdomen. In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions of the creature's body, each of which is in turn composed of multiple segments. The human thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain. Etymology The word thorax comes from the Greek θώραξ ''thorax'' "breastplate, cuirass, corslet" via la, thorax. Plural: ''thoraces'' or ''thoraxes''. Human thorax Structure In humans and other hominids, the thorax is the chest region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the rib cage, spi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sternum
The sternum or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury. Shaped roughly like a necktie, it is one of the largest and longest flat bones of the body. Its three regions are the manubrium, the body, and the xiphoid process. The word "sternum" originates from the Ancient Greek στέρνον (stérnon), meaning "chest". Structure The sternum is a narrow, flat bone, forming the middle portion of the front of the chest. The top of the sternum supports the clavicles (collarbones) and its edges join with the costal cartilages of the first two pairs of ribs. The inner surface of the sternum is also the attachment of the sternopericardial ligaments. Its top is also connected to the sternocleidomastoid muscle. The sternum consists of three main parts, listed from the top: * Manubrium * Body (gladiolus) * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Median Plane
The median plane also called a mid-sagittal plane is used to describe the sagittal plane as it bisects the body vertically through the midline marked by the navel, dividing the body exactly in left and right side. The term parasagittal plane is used to refer to any plane parallel to the sagittal and median plane. It is one of the lines used to define the right upper quadrant of the human abdomen. The midsternal line can be interpreted as a segment of the median plane. File:Sagittal brain MRI.jpg, Median plane magnetic resonance imaging of the head. File:Median plane CT scan of a pregnancy of 37 weeks of gestational age.jpg, Median plane CT scan of a pregnant woman. The fetus (exposed in the coronal plane) is 37 weeks of gestational age In obstetrics, gestational age is a measure of the age of a pregnancy which is taken from the beginning of the woman's last menstrual period (LMP), or the corresponding age of the gestation as estimated by a more accurate method if available ...

Midclavicular Line
{{short description, None 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. * Parasternal line: A vertical line equidistant from the sternal and mid-clavicular lines. * Mid-clavicular line: A vertical line passing through the midpoint of the clavicle. * Mammillary line * Anterior axillary line: A vertical line on the anterior torso marked by the anterior axillary fold. * Midaxillary line: A vertical line passing through the apex of the axilla. * Posterior axillary line: A vertical line passing through the posterior axillary fold. * Scapular line: A vertical line passing through the inferior angle of the scapula. * Paravertebral line: A vertical line corresponding to the tips of the transverse process ...
