Document Summary
Identifies stimulus: sends the stimulus through the cns to the brain. The performance of fast movements that are too quick to be guided by feedback. The optimal speed and accuracy in human performance. The transmission of sensory information from sensory receptors to the cns. The transmission of motor information from the cns to effectors. The signals that are sent between different areas of the cns. When receptors convert environmental energy into electrical impulses: e. g. Our central representation of how our limbs are moving. Our sense of movement and balance: through detecting rotational movements and linear accelerations. Environmental energy gets converted into electrical impulses. The stimulus needs to exceed the receptor threshold to send a nerve impulse to the cns. Low level reflexes are integrated in the spinal cord: these are the synapses in the spinal cord which create the motor output, this is for voluntary responses so it is much faster.
