Anatomy & Physiology Practice Questions

Chapter 14: The Peripheral Nervous System

What is a Nerve? How are Nerves protected? How are cranial nerves named and numbered? How many are there? What is the difference between a mixed cranial nerve and a sensory cranial nerve? How are somatic motor axons different from autonomic motor axons? Where do the motor axons of the facial nerve originate?

Through which foramen does the glossopharyngeal nerve exit the skull? How are the spinal nerves named and numbered? How do spinal nerves connect to the spinal cord? Why are all spinal nerves classified as mixed nerves? Where do the posterior and anterior rami originate and what regions of the body does each serve?

List the components of a reflex arc in order: Define each of the following terms in relation to reflex arcs:  Monosynaptic:  Poly synaptic:  Reciprocal Innervation:  Intersegmental: What are the main input and output components of the autonomic nervous system?

What are the effectors of the Somatic Nervous System?  What are the effectors of the Autonomic Nervous System? How is the motor neuron pathway of the ANS different from the motor neuron pathway of the SNS? What is Dual Innervation? What is the functional difference between Preganglionic and Postganglionic neurons?

What are the functions of the Enteric Nervous System? Define Cholinergic and Adrenergic neurons: Which neurotransmitters bind to cholinergic receptors and which bind to adrenergic receptors? Which Autonomic neurons produce a shorter effect, cholinergic or adrenergic? Why?

Which part of the brain controls the balance between sympathetic and parasympathetic tone? What happens during the fight-or-flight response?  Which division of the ANS is responsible? What happens during the rest-and-digest response of the parasympathetic division of the ANS? Describe the sympathetic response in a frightening situation for each of the following body parts: Iris of the Eye, Lungs, Urinary Bladder, Stomach, Intestines, Heart, Arterioles of the Abdominal Viscera, and Arterioles of the Skeletal Muscles. Give three examples of the opposite effects of the sympathetic and parasympathetic divisions of the autonomic nervous system:
