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.

Question

Explain the ascending pathway of how the information about touch sensation travels from the right arm up to the brain where he is aware that he has been touched. (Use complete sentences.) Use these key words in this order: sensory neuron, radial nerve in brachial plexus, spinal nerve, dorsal root ganglion, dorsal root, dorsal horn in cervical spinal cord, ascending tract, decussate, somatosensory cortex in postcentral gyrus, parietal lobe, Mr. Dexter thinks “Someone touched my arm.”)

Question

Chapter 10, Problem 29RQ

Summary Introduction

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.

Summary Introduction

To determine: The function of the vestibular apparatus in notifying the brain of the movements.

Introduction: 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 about one another and the environment.
