To sketch: The diagram of various structures of vestibular apparatus that are involved in providing equilibrium and their role in regulating the brain movement.
Introduction: Equilibrium is a state of balance. It is used to describe the ion concentration in body fluids and the position of body in space. The dynamic component of equilibrium tells about the movement through space. The static component of equilibrium tells if the head of an individual is not in its normal upright position. The sensory information from the inner ear combined with signals from joint and muscle proprioceptors tells the brain about the localization of the body parts in relation to one another and the environment.
To determine: The function of the vestibular apparatus in notifying the brain of the movements.

- Describe the role of the vestibular apparatus in maintaining equilibrium.arrow_forwardDescribe what happens to the body when the reticular formation receives sensory impulses, and what happens when it does not receive stimulation.arrow_forwardDescribe the location and function of the ventral stream of visualprocessing areas in the cerebral cortex. Then explain why the dorsal and ventral visual streams are called the “where” and “what” streams, respectively.arrow_forward
