Know the reflex control pathway and what each thing does.

Use logic to determine whether each of the following reflexes is a somatic reflex or an autonomic (visceral) reflex. Hint: think about what the effector is — is it a skeletal muscle, or is it a smooth / cardiac muscle or gland? -Patellar (knee-jerk) reflex                                                    -Pupillary light reflex                            (autonomic/somatic)                                                    -Effectors are skeletal muscles               (autonomic/somatic)                                                    -Effectors are smooth muscles or glands   (autonomic/somatic)                                                    -Regulation of blood pressure        (autonomic/somatic)                                                    -Salivary reflex             (autonomic/somatic)

Where is the cell body of the forth structure reflex arc located?

Here is the question: Question Intro to Neuroscience Question: Students are celebrating the end of the year and have gotten together for a few ice-old Pepsi’s. Sarvesh holds out his mug for a refill and when Nicole starts to pour soda in, the mug slips down slightly but Sarvesh quickly recovers to prevent his mug from spilling. Which of the following does NOT occur in this reflex circuit? Group of answer choices a) The added load of the soda stretches the intrafusal muscle fibers of the bicep b) Sensory neurons from the muscle spindle synapse onto α motor neurons and interneurons c) The rate of action potential firing increases in the muscle spindle fiber d) Excitation of motor neurons innervating the bicep muscle e)All of the above *do* occur       Possible explanation/reasoning: a) The added load of the soda stretches the intrafusal muscle fibers of the bicep Yes, the event described in a) is likely to occur. When an added load (in this case, the soda being poured) is…
