A sagittal plane (also known as anteroposterior plane) is perpendicular to the ground, separating left from right. The median (or midsagittal) plane is the sagittal plane in the middle of the body; it passes through midline structures such as the navel and the spine. All other sagittal planes (also known as parasagittal planes) are parallel to it.
S-curve (art) Contrapposto (Italian pronunciation: [kontrapĖposto]) is an Italian term that means "counterpoise". It is used in the visual arts to describe a human figure standing with most of its weight on one foot, so that its shoulders and arms twist off-axis from the hips and legs in the axial plane.
Ancient Egyptian art used a canon of proportion based on the "fist", measured across the knuckles, with 18 fists from the ground to the hairline on the forehead. [3] This canon was already established by the Narmer Palette from about the 31st century BC, and remained in use until at least the conquest by Alexander the Great some 3,000 years later.
The coronal plane, also called the frontal plane, which divides the body into front and back. [2] The transverse plane, also called the axial plane or horizontal plane, which is perpendicular to the other two planes. [2] In a human, this plane is parallel to the ground; in a quadruped, this divides the animal into anterior and posterior ...
Many books such as Human Anatomy for Artists: The Elements of Form, are written as a guide to drawing the human body anatomically correctly. [4] Leonardo da Vinci sought to improve his art through a better understanding of human anatomy. In the process he advanced both human anatomy and its representation in art.
When in lying position, the body may assume a great variety of shapes and positions. The following are the basic recognized positions: Supine position: lying on the back with the face up; Prone position: lying on the chest with the face down ("lying down" or "going prone") Lying on either side, with the body straight or bent/curled forward or ...
The most commonly used reference planes are: Axial or "transverse" or "horizontal", the plane that is horizontal and parallel to the ground with the body standing in the standard anatomical position. It contains (and thus is defined by) the lateral and the medial axes of the brain.
The axial skeleton (80 bones) is formed by the vertebral column (32–34 bones; the number of the vertebrae differs from human to human as the lower 2 parts, sacral and coccygeal bone may vary in length), a part of the rib cage (12 pairs of ribs and the sternum), and the skull (22 bones and 7 associated bones).
