37. A person can sense a range of temperature stimulus such as cold, warm and hot because: 1. Different types of neurons are being triggered. 11. Each neuron can be triggered a partial amount (25% for cold, 50% for warm, and 100% for hot) 111. The frequency of the nerve impulse fluctuates when a stimulus is detected. IV. More nerves meeting the minimum threshold levels are firing and responding to the stimulus. a) l and III are correct d) Only II is correct b) Ill and IV are correct e) Only IV is correct c) l and II are correct 38. What type of neuron will connect to a muscle, causing it to contract? a) sensory neuron d) cortex neuron b) spinal neuron e) interneuron 0) motor neuron 39. Which statement is FALSE? a) Dopamine is a neurotransmitter that plays a role in pleasurable reward and motivation. b) The two branches of the nervous system are the central and peripheral nervous systems. 0) Dendrites receive information and conduct signals toward the cell body. d) The excitatory response involves making the neuron more negative on the inside, while the inhibitory response involves the opening of sodium gates, triggering a wave of depolarization. e) The \"fight or flight\" response illustrates how the sympathetic nervous system regulates many physiological processes in the body. 40. Where would you expect to nd the structure indicated by the arrow on the right? a) In your peripheral nenrous system b) In your central nervous system - :1; Q' c) Relaying messages between sensory and motor neurons 3' d) A and B are correct \\ (9\" e B and C are correct 1
