Question
100) Reciprocal inhibition means that while one sensory B' nerve is stimulated, another sensory neuron for synergistic muscles in the same area is inhibited and cannot respond. 101) Symphyses are synarthrotic joints designed for strength with flexibility 102) Once a motor neuron has fired, all the muscle fibers in a muscle contract. 103) As pressure in the aorta rises due to atherosclerosis, more ventricular pressure is required to open the aortic valve 104) Changes in arterial pH can modify respiration rate and rhythm even when carbon dioxide and oxygen levels are normal. 105) Oxygenated hemoglobin releases oxygen more readily when the pH is more basic.Explanation / Answer
100) False. Reciprocal inhibition : One sensory neuron stimulates agonist and other inhibits antagonist. They work on opposing muscles and helps movement.
101) False.Symphyses are amphiarthrodial joints designed for slight movements alone with flexibility while synarthrodial joints immovable joints.
102) True: If one motar neuron fires it results in contraction of all muscle fibers in a muscle.
103) True: Increase in aortic pressure results in direct increase of ventricular force on the left ventricle in order to eject blood.
104) False: Only altered CO2 levels can activate as H+ ions cannot pass through and reach meddula
105) False: In acidic condition, hemoglobin releases oxygen more readily- Bohrs'effect
