Human head Human head In human anatomy, the head is at the top of the human body. It supports the face and is maintained by the skull, which itself encloses the brain. The human head consists of a fleshy outer portion, which surrounds the bony skull. The brain is enclosed within the skull. The head rests on the neck, and the seven cervical vertebrae support it. The human head typically weighs between The face is the anterior part of the head, containing the eyes, nose, and mouth. On either side of the mouth, the cheeks provide a fleshy border to the oral
Group actions in computational anatomy model of human anatomy in computational anatomy is a Groups and group action, a classic formulation from differential geometry. The orbit is called the space of shapes and forms. The space of shapes are denoted formula_1, with the group formula_2 with law of composition formula_3; the action of the group on shapes is denoted formula_4, where the action of the group formula_5 is defined to satisfy The orbit formula_7 of the template becomes the space of all shapes, formula_8. The central group in CA defined on volumes in formula_9 are the diffeomorphism group formula_10 which are mappings with 3-components formula_11,
