Peripheral and Autonomic Nervous System Lab Quiz
sensory neuron
A points to an axon which belongs to a ------------------- neuron
sympathetic nervous system
After exercising your heart rate goes up. Which system is responsible for this increase in heart rate?
effector, respond to the stimulus
Identify A which is the part of a reflex arc. What is it's function?
XI cranial nerve
Identify nerve A which you test when you elevate and depress your shoulders and turn your head from side to side?
XII cranial nerve
Identify nerve B which you test when you ask a person to protrude his/her tongue?
sciatic nerve
Identify the nerve the arrow points to
V cranial nerve
Identify the nerve the arrow points to which supplies muscles which help in closing the jaw and are also called muscles of mastication.
optic nerve
Identify the nerve the arrow points to.
receptor; site of stimulus action
Identify the structure the arrow points to . What is it's function?
sensory and travel towards the spinal cord
Impulses travelling in 'A' are:
autonomic reflex
In the activity where you shone a light into the subject's eye, you should have seen the pupils constrict. What kind of reflex were you demonstrating?
motor neuron
The arrow 'A" points to an axon which belongs to a ___________ neuron.
olfactory
The arrow points to a structure that is related to which cranial nerve?
somatic stretch reflex; spinal cord only
The patellar reflex is an example of which type of reflex. Which parts of the nervous system does it involve?
somatic cranial reflex (involving a cranial nerve)
This image here shows a reflex where a foreign object on contact with the cornea sets up impulse transmission along the V nerve, to the brain and the efferent pathway is by way of the VII nerve to the orbicularis oculi muscle, causing it's contraction. How would you classify this reflex?
II and III cranial nerves
What nerves are you testing when you do the pupillary light reflex?
sense of smell
What sensations are carried by this nerve
sense of vision
What sensations does this nerve carry?
Autonomic: sympathetic
What type of reflex is the ciliospinal reflexWhich system / nerve is being tested here?
somatic cranial nerve reflex
What type of reflex is the corneal reflex?
facial nerve
Which nerve is involved in carrying taste from the anterior 2/3rds of the tongue as well as lacrimation?
V and VII
Which nerves are involved in the corneal reflex?
III, IV, and VI
Which nerves supply muscles that move the eyeball also called extraocular muscles?
B
Which of the nerves seen below is related to the medial epicondyle of the humerus and called the 'funny bone nerve'?
A
Which of the nerves seen below is the axillary nerve?
adjustment of lens for near vision, decreased heart rate, pupillary constriction
what are the functions of the parasympathetic nervous system?
dilation of the airway passages, constriction of the blood vessels of the skin, increase in metabolic rate
what are the functions of the sympathetic nervous system
Endoneurium
what does b point too?
