| | a), b) and c) are all correct. |
Human sensory systems (select the MOST CORRECT statement):
| | Sensory information for both vision and touch is relayed toseparate regions of the cerebral cortex, but in both cases relieson ascending spinal tracts to reach the brain. |
| | The location of a stimulus such as touch is coded by theamplitude of the action potentials in the afferent neuron. |
| | Baroreceptors in the aortic arch respond to changes in bloodpressure that are sensed by mechanoreceptors. |
