+# Overview of Body Models
+
+Each body part is implemented utilizing data from detailed cadaver/anatomy
+studies, thus ensuring high accuracy and anatomical fidelity.
+
+See the section below for a more detailed description of the models and the underlying anatomical data.
+
+::::{dropdown} **Background**
+
+The body models live in the `Body/` subfolder within your AMMR directory. The folder names and organization here depend on
+the origin of the models.
+
+By far the most important folder is the `Body/AAUHuman`, which
+contains the AnyBody full body model. It was originally developed at Aalborg
+University, Denmark (with the acronym AAU) but also consists of body-parts (trunk
+and extremities) that were either developed elsewhere or based on data sets
+from elsewhere.
+
+Two mandible models have also been developed but are yet to be assembled with
+the AAUHuman. These two mandible models can be found in `Body/Mandible`
+
+The `Body/Beta` folder contains less developed and tested models.
+
+The different body parts included in the full body model are derived from
+various anatomical databases from literature.
+
+The segmental coordinate systems are constructed using the original data. To ensure having a well defined coordinate system for all segments an anatomical frame has been defined, the anatomical frame is constructed using well defined bony landmark locations on the bone.
+
+The full body model
+contains shoulder/arm, trunk, foot and multiple leg models
+which can be assembled into the full human in many combinations.
+
+:::{note}
+Parts of the AAUHuman (except the
+mandible) are by default assembled together into a full body model.
+See {doc}`/bm_config/index` for re-configuring the model to for example, only represent the trunk, or use a different leg/muscle model.
