Which of the following is stimulated by the Sympathetic nervous system?   Question 9 options:   Increased dilation of respiratory tubes in lungs during exercise   Increased contractions of the digestive system for peristalsis   Increased contractions of rectum muscles to defecate   Increased saliva and tear production   Increased contractions of urinary bladder to urinate

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)

Which of the following choices correctly describes a sensory pathway resulting in stimulation of a motor pathway? a. Sensory receptors → sensory pathway → parietal lobe → motor pathway → muscles b. Sensory neuron → spinal cord → motor neuron c. Sensory neuron → brain → motor neuron d. Sensory receptors → sensory pathway → spinal cord → motor pathway → muscles
