Final answer:
The statement regarding local anesthesia and eye movement requires additional context to determine truthfulness, while the statement about normal reaction being a force that acts in the direction of gravity is false. Moreover, proprioception tests involve sensing movement in extremities to gauge neurological function.
Step-by-step explanation:
The statement 'Local anesthesia! Eye grasped (forceps or cotton-tipped applicator) and moved in direction (towards or opposite) to that which mechanical restriction is suspected.' is not clearly true or false without additional context. In medicine, particularly ophthalmology and neurology, different tests and procedures involving the eyes and sensory testing may require specific techniques. For example, in certain eye examinations, the eye may be moved in a specific direction to test for mechanical restriction or muscle function. Sensory testing with a cotton-tipped applicator is a common procedure to assess sensation and discriminate between sharp and dull stimuli, important for evaluating neurological function.
The concept that 'Normal reaction is the force that opposes the force of gravity and acts in the direction of the force of gravity' is false. Normal reaction, also known as the normal force, opposes the force of gravity but acts in a direction perpendicular to the surface of contact, not in the direction of the force of gravity.
Regarding the test of proprioception, patients are asked to sense the movement of their fingers or toes to assess their proprioceptive abilities. This is achieved by moving these body parts and asking the patient to identify the movement, helping to evaluate the integrity of nerve pathways and brain function related to proprioception.
