5 Written Questions

1. neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs
2. carry incoming information from the sensory receptors to the brain and spinal cord
3. analysis that begins with the sensory receptors and works up to the brain's integration of sensory information
4. the study of relationships between the physical characteristics of stimuli such as their intensity and our psychological experience of them
5. the synapse is the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron . The gap between the junction is called the synaptic gap

5 True/False Questions

1. Signal detection theory → A theory predicting how and when we detect a presence of a faint stimulus amid background stimulation. Assumes there is no single absolute threshold and detection depends partially on a person's experience, expectations, and motivations, and level of fatigue

   True        False

2. • ANS, know divisions and actions (sympathetic & parasympathetic nervous systems) → The part of the peripheral nervous system that controls the glands and the muscles of the internal organs. The sympathetic division arouses while the parasympathetic calms. It also controls glandular activity, heartbeat, and digestion. It can be consciously overridden but it usually it operates on its own.

   True        False

3. Retina → a layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly greater transmission speed of neural impulses hops from one node to the next

   True        False

4. What do rods do → detect white, black, and gray

   True        False

5. Axon → The extension of a neuron ending a branching terminal fibers through which messages pass to other neurons or to muscles or to glands

   True        False
