This is common in English and I think it's probably what "esquema corporal" is referring to:

"Body schema is a concept used in several disciplines, including psychology, neuroscience, philosophy, sports medicine, and robotics. The neurologist Sir Henry Head originally defined it as a postural model of the body that actively organizes and modifies 'the impressions produced by incoming sensory impulses in such a way that the final sensation of [body] position, or of locality, rises into consciousness charged with a relation to something that has happened before'. [...]
A clear differentiation of body schema from body image has developed gradually."

"Body awareness can be divided into three parts. These are:
1. Body image -The subjective experience of his own body, which is based upon emotional factors, peer group and other social interactions, specific career and social aspirations and cultural values. Body image may differ from the actual image.
2. Body concept (referred to body image by Cratty and Sams, 1968) -The knowledge a person has of his own body which is acquired through a conscious learning process. It involves identification, function and location of body parts as well as body planes, body parts, body movement, laterality , and directionality.
3. Body schema -It is unconscious and changes from moment to moment. It is derived from stimulations produced within the body (proprioception). This information is used to regulate the body and the position of different muscles and parts of body in relation to each other and the pull of gravity.
Knowledge of body schema and concepts are the basis for spatial and directional concepts."
