The muscles of internal rotation include: of arm/humerus at shoulder. Anterior part of the deltoid muscle [1] Subscapularis [1] Teres major [1] Latissimus dorsi [1] Pectoralis major [1] of thigh/femur at hip [2] Tensor fasciae latae; Gluteus generalis; Anterior fibers of Gluteus meralis; Adductor longus and Adductor brevis; of leg at knee [3 ...
Any extrinsic rotation is equivalent to an intrinsic rotation by the same angles but with inverted order of elemental rotations, and vice versa. For instance, the intrinsic rotations x-y’-z″ by angles α, β, γ are equivalent to the extrinsic rotations z-y-x by angles γ, β, α. Both are represented by a matrix
Anatomical terminology is a specialized system of terms used by anatomists, zoologists, and health professionals, such as doctors, surgeons, and pharmacists, to describe the structures and functions of the body.
Motion, the process of movement, is described using specific anatomical terms.Motion includes movement of organs, joints, limbs, and specific sections of the body.The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved.
This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
Rotation (anatomy) Rotation (mathematics) Rotation (medicine), medical student training; Rotation (physics), ratio between a given angle and a full turn of 2π radians; Circular shift, an operation on a tuple; Bitwise rotation, a mathematical operator on bit patterns; Curl (mathematics), a vector operator
They constitute a mixed axes of rotation system, where the first angle moves the line of nodes around the external axis z, the second rotates around the line of nodes and the third one is an intrinsic rotation around an axis fixed in the body that moves. These rotations are called precession, nutation, and intrinsic rotation.
Other disciplines use different terms (such as dextro-and laevo-rotary in chemistry, or clockwise and anticlockwise in physics) or simply use left and right (as in anatomy). Relative direction and chirality are distinct concepts.
