Knowra Body schema Body schema Body schema is the brain’s continually updated representation of the body’s shape, position, and movement. It supports posture and action without requiring conscious attention.
Proprioception : The sense of the body’s position and movement, arising from signals in muscles, tendons, and joints. Its signals help update the body schema as limbs move.
Body image : A person’s conscious perceptions, beliefs, and feelings about their body. Unlike body schema, body image includes conscious beliefs and attitudes about appearance.
Tool use : The use of external objects to perform actions beyond the unaided body’s reach or ability. Skilled tool use can extend action-related representations beyond the skin.
Henry Head : A British neurologist known for clinical research on sensation and neurological function. Head introduced the term “body schema” to describe a postural model used in movement.
Somatosensory system : The sensory system that processes touch, temperature, pain, and bodily position. It supplies touch and position information used to represent the body.
Body ownership : The sense that a body or body part belongs to oneself. Ownership concerns whose body it is; body schema concerns its usable shape and position.
Motor control : The processes by which the nervous system plans, coordinates, and adjusts movement. Body schema helps guide movement by supplying an estimate of bodily configuration.
Gordon Holmes : A British neurologist whose studies linked brain injury with disorders of vision and bodily position sense. His clinical observations helped clarify how position sense supports awareness of the body.
Multisensory integration : The nervous system’s combination of information from different sensory modalities. Combining vision, touch, and proprioception helps align the body representation.
Body representation : The collection of neural representations of the body used for perception, thought, and action. Body schema is one action-oriented form of the broader body representation.
