Sense of balance
Sense of Balance
The Sense of Balance (pronunciation: /ˈsɛns ɒv ˈbæləns/) is a complex sensory system in the human body that helps to maintain posture and equilibrium, even when the body is moving or when the surface beneath the body is moving or uneven.
Etymology
The term 'Sense of Balance' is derived from the Latin words 'sensus' meaning 'perception' or 'feeling', and 'bilanx' meaning 'having two scales', which refers to the state of equilibrium.
Function
The Sense of Balance is primarily controlled by a complex network of sensory neurons, vestibular system, visual system, and proprioceptors. These systems work together to send signals to the brain about the body's position and movement, allowing the body to maintain balance and stability.
