Question 1
Which two major nerves are responsible for sensory (touch) information of the hand?
Answers:            
Ulnar and Radial nerves
Radial and Medial nerves
Axillary and Ulnar nerves
 Ulnar and Medial nerves
Question 2
Which of the following choices forms the Sciatic nerve and branches into the Tibial and Common Fibular Nerves?
Answers:            
Cervical Plexus
Brachial Plexus
Lumbar Plexus
 Sacral Plexus
Question 3
Which of the following choices is an effect of the parasympathetic nervous system?
Answers:            
Increased blood flow to skeletal muscles
Increased blood pressure
Dilation of the bronchi in the lungs to increase airflow
 Stimulates elimination of wastes such as feces and urine
Question 4
Upper motor neurons are efferent neurons that originate in the cerebrum or brain stem.
Answers:            
 True
False
Question 5
A ganglia is a collection of nerve cell bodies within the peripheral nervous system.
Answers:            
 True
False
Question 6
Which of the following choices is true regarding reflexes?
Answers:            
Neural integration (processing) of all reflexes occurs in the brain
 Somatic reflexes activate skeletal muscle
The motor neuron of a reflex arc transmit afferent impulses to the spinal cord
The stretch or tendon reflexes are only present in children under 5 years of age
Question 7
Which major nerve is the largest and thickest nerve in the body and innervates a majority of the entire lower limb?
Answers:            
 Sciatic nerve
Ulnar nerve
Sacral nerve
Axillary nerve
Question 8
Which of the following choices is an effect of the sympathetic nervous system?
Answers:            
Decreased heart rate
Increased blood flow to the gastrointestinal system
 Increased blood pressure
Constriction of the pupils
Question 9
Which statement is true regarding spinal nerves?
Answers:            
The dorsal root of the spinal nerve will contain motor fibers (axons) that innervate the skeletal muscles
 All 31 spinal nerves contain thousands of individual nerve fibers (axons) carrying information to and from the spinal cord
Spinal nerves only innervate the skin, muscles and joints
Each spinal nerve is designated as a motor nerve only or a sensory nerve only
Question 10
Which of the following best describes the deep tendon reflex?
Answers:            
 Muscle contraction occurs when its tendon is stretched quickly in order to protect the muscle/tendon from tearing injury.
It’s always initiated by a painful stimulus
Causes an automatic response that withdrawals the body from a painful stimulus
It accompanies the flexor response to prevent movement.
Question 11
The sympathetic nervous system is responsible for which of the following functions?
Answers:            
 Dilating pupils
Constricting bronchioles
Decreasing blood pressure
Increasing urinary function
Question 12
Which of the following components is the first step in the reflex arc?
Answers:            
 Receptor
Sensory neuron
Integration
Effector
Question 13
A lower motor neuron only innervates skeletal muscles.
Answers:            
 True
False
Question 14
Which cranial nerve is associated with sensory information of most of the face, assists in innervating the muscles of mastication and is divided into three divisions?
Answers:            
 CN V:  Trigeminal nerve
CN XI:  Accessory nerve
CN XII:  Hypoglossal nerve
CN VII:  Facial nerve
Question 15
Which of the following cranial nerves is responsible for the sensory function of smell?
Answers:            
 CN I
CN II
CN V
CN VIII
