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)
Place the following concepts in the correct order to explain how a reflex works:
Target organs , Afferent neuron , Sensory receptor , Interneuron , Motor neuron
List the components of reflex arc in correct sequence?

- Describe a situation where a reflex arc would be activated that is not described in your lesson. Assume that the reflex arc has five components to it. Please choose a reflex that involves a body part below the neck. (If you have trouble with this, do an internet search for information on reflex arcs.) Which type of structure was first stimulated in the reflex arc? What is the name of the second structure involved in the reflex arc? Into what part of the nervous system did the second structure send its electrical signal? What is the name of the third structure involved in the reflex arc? Where is this third structure located? What is affected by the electrical signal sent by the third structure? (This will be the fourth structure in the arc.) Where is the cell body of the fourth structure located?
