Anatomical terms of locationStandard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, Terminologia Anatomica, Terminologia Neuroanatomica, and Terminologia Embryologica for humans and Nomina Anatomica Veterinaria for animals. These allow parties that use anatomical terms, such as anatomists, veterinarians, and medical doctors, to have a standard set of terms to communicate clearly the position of a structure.
RhinoplastyRhinoplasty (Ancient Greek: ῥίς, romanized: rhī́s, nose + Ancient Greek: πλάσσειν, romanized: plássein, to shape), commonly called nose job, medically called nasal reconstruction, is a plastic surgery procedure for altering and reconstructing the nose. There are two types of plastic surgery used – reconstructive surgery that restores the form and functions of the nose and cosmetic surgery that changes the appearance of the nose. Reconstructive surgery seeks to resolve nasal injuries caused by various traumas including blunt, and penetrating trauma and trauma caused by blast injury. Reconstructive surgery can also treat birth defects, breathing problems, and failed primary rhinoplasties. Rhinoplasty may remove a bump, narrow nostril width, change the angle between the nose and the mouth, or address injuries, birth defects, or other problems that affect breathing, such as a deviated nasal septum or a sinus condition. Surgery only on the septum is called a septoplasty. In closed rhinoplasty and open rhinoplasty surgeries – a plastic surgeon, an otolaryngologist (ear, nose, and throat specialist), or an oral and maxillofacial surgeon (jaw, face, and neck specialist), creates a functional, aesthetic, and facially proportionate nose by separating the nasal skin and the soft tissues from the nasal framework, altering them as required for form and function, suturing the incisions, using tissue glue and applying either a package or a stent, or both, to immobilize the altered nose to ensure the proper healing of the surgical incision.
Transverse planeA transverse plane is a plane that is rotated 90° from two other planes.
Sagittal planeThe sagittal plane (; also known as the longitudinal plane) is an anatomical plane that divides the body into right and left sections. It is perpendicular to the transverse and coronal planes. The plane may be in the center of the body and divide it into two equal parts (mid-sagittal), or away from the midline and divide it into unequal parts (para-sagittal). The term sagittal was coined by Gerard of Cremona.
Anatomical planeAn 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 anatomy and non-human anatomy, four principal planes are used: the median plane, sagittal plane, coronal plane, and transverse plane. The median plane or midsagittal plane passes through the middle of the body, dividing it into left and right halves. A parasagittal plane is any plane that runs parallel to the median plane, also dividing the body into left and right sections. The dorsal plane divides the body into dorsal (towards the backbone) and ventral (towards the belly) parts. In human anatomy coronal plane is preferred, or sometimes the frontal plane, and the description may reference splitting the body into front and back parts, but this phrasing is not as clear for animals with a horizontal spine like quadrupeds or fish. The transverse plane, also called the axial plane or horizontal plane, is perpendicular to the other two planes. In an animal with a vertical craniocaudal axis, like a human, this plane is parallel to the ground; in an animal with a horizontal craniocaudal axis, like a quadruped, the coronal plane divides the animal into anterior and posterior sections.
Anatomical terms of neuroanatomyThis article describes anatomical terminology that is used to describe the central and peripheral nervous systems - including the brain, brainstem, spinal cord, and nerves.
Dorsal planeThe dorsal plane (also known as the coronal plane or frontal plane, especially in human anatomy) is an anatomical plane that divides the body into dorsal and ventral sections. It is perpendicular to the sagittal and transverse planes.
