![]() ![]() You can imagine the ‘fulcrum’ as being loosely through the two hip bones and sacrum. Reference axes: The movement is in the sagittal plane.Anatomical structures: The vertebral column moves relative to the sacrum and hip bone.During extension it straightens, increasing the angle relative to the arm. Direction: During flexion, the forearm moves upwards and ‘closer’ to the arm, resulting in a decreased angle between them.The fulcrum is provided by the elbow joint, around a frontal/coronal axis. More precisely, the ulna (one of the two forearm bones) moves relative to the humerus (bone of the arm). Anatomical structures: The forearm moves relative to the arm.During extension, it moves forwards (anteriorly).įlexion and extension of the elbow joint can be described as follows: Direction: During flexion, the leg moves backwards (posteriorly).The fulcrum is provided by the knee joint, through which the frontal/coronal axis passes. Anatomical structures: The tibia of the leg moves relative to the femur of the thigh.( Supinate: palm towards the Sun, Pronate: palm towards the Plants)Ĭombination of: flexion, abduction, extension, adductionīringing the thumb in contact to a fingerįlexion and extension of the knee consist of the following: Mnemonic: ' Supinate to the Sun and Pronate to the Plants' Lateral rotation of the radius, resulting in the palm of the hand facing anteriorly (if in anatomical position) or superiorly (if elbow is flexed) Medial rotation of the radius, resulting in the palm of the hand facing posteriorly (if in anatomical position) or inferiorly (if elbow is flexed) Key facts about the movements in the human body Flexion Planes and relations eventually catch up with students because they are constantly used to relate anatomical structures together, but movements are usually forgotten or poorly understood. However, the basic concepts of planes, relations, and especially anatomical movements are glanced over in perhaps the first 30 minutes to 1 hour. If you see the glass half empty, there is only one specific term that can accurately describe an anatomical structure/movement/relation, which means there are a lot of words that you need to learn in order to become fluent in this language.Īlmost every anatomy department in the world naturally focuses its resources on teaching students the names and details of bones, muscles, vessels, nerves, etc. ![]() If you see the glass half full, the language is extremely precise and exact, leaving no room for errors, misinterpretation, or miscommunication. This can simultaneously be a blessing and a curse. In order to understand fellow medical students and physicians, you need to have an excellent grasp of the anatomical language. They will be grouped in pairs of ‘antagonistic actions’ (actions that oppose one another), just like certain muscle groups. This article will shed some light on the various types of movements in the human body. Lateral flexion of spine, Flexio lateralis spinae ![]()
