The human body is capable of a wide variety of positions, as exemplified by this energetic yoga position, "astavakrasana". Human positions refer to the different physical configurations that the human body can take. There are several synonyms that refer to human positioning, often used interchangeably, but having specific nuances of meaning. [1]
Proprioceptive signals are transmitted to the central nervous system, where they are integrated with information from other sensory systems, such as the visual system and the vestibular system, to create an overall representation of body position, movement, and acceleration. In many animals, sensory feedback from proprioceptors is essential for ...
The brain uses information from the vestibular system in the head, and from proprioception throughout the body to enable an understanding of the body's dynamics and kinematics (including its position and acceleration) from moment to moment.
The main functions of the somatosensory system are the perception of external stimuli, the perception of internal stimuli, and the regulation of body position and balance (proprioception). [2] Mechanosensory information includes that of light touch, vibration, pressure and tension in the skin.
The balance system works with the visual and skeletal systems (the muscles and joints and their sensors) to maintain orientation or balance. Visual signals sent to the brain about the body's position in relation to its surroundings are processed by the brain and compared to information from the vestibular and skeletal systems.
Body schema is an organism's internal model of its own body, including the position of its limbs. 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 ...
Postural control refers to the maintenance of body posture in space. The central nervous system interprets sensory input to produce motor output that maintains upright posture. [1] Sensory information used for postural control largely comes from visual, proprioceptive, and vestibular systems. [2]
The egocentric reference frame refers to a proprioceptive reference frame using the position of an organism's body in a space. This reference frame relies heavily on somatosensory information, or feedback from the body's sensory system. Muscle vibrations can be used to alter a subject's perception of the location of their bodies by creating an ...
