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?
