A

Hypoglossal; Movement of tongue

13
Q

Why do we have reflexes?

A

Protection

14
Q

What is the reflex arc?

A
  • Involuntary defense mechanism

- Also helps with balance and muscle tone

15
Q

What are the 4 types of reflexes?

A

Deep tendon
Superficial
Visceral
Pathologic

16
Q

What is an example of a deep tendon reflex?

A

Knee jerk

17
Q

What is an example of a superficial reflex?

A

Corneal and abdominal

18
Q

What is an example of a visceral reflex?

A

Pupillary

19
Q

What is an example of a pathologic reflex?

A

Babinski

20
Q

What does a 4+ reflex mean?

A

Very brisk, hyperactive with clonus, indicated disease

21
Q

What does a 3+ reflex mean?

A

Brisker than average, probably normal

22
Q

What does a 2+ reflex mean?

A

Average, normal

23
Q

What does a 1+ reflex mean?

A

Diminished, low normal, or requires reinforcement

24
Q

What does a 0 reflex mean?

A

No response

25
Q

How do you determine if a patient has clonus?

A

Dorsiflex the foot and support the leg and hold pressure; there is involuntary, continuous movement in the foot

26
Q

When checking for reflexes, where do you focus: the reflex or the muscle movement?

A

Muscle movement

27
Q

When checking biceps reflex, where do you look?

A

Biceps muscle

28
Q

When checking triceps reflex, where do you look?

A

Triceps

29
Q

When checking patellar tendon, where do you look?

A

Quadriceps reflex

*Make sure to know how to check this reflex if a patient is laying in bed

30
Q

When checking the Achilles reflex, where do you look?

A

Focus on calf muscle

31
Q

What reflex is normal in infants but not normal to see in adults?

A

Positive babinski (fanning of the toes)

32
Q

What are some examples of cerebellar function tests?

A
  • Rapid alternating movements
  • Finger to finger test
  • Finger to nose test
  • Heal to shin test
  • Romberg test (heels together)
  • Gain
33
Q

What is a vibration test used to determine?

A

Peripheral neuropathy (no vibrations means you have this)

34
Q

What type of patients may have no vibrations, and hence no peripheral neuropathy

A

Diabetics

Alcoholics

35
Q

What is stererognosis?

A

The only way to know what is in the hand is by looking at it (done in the hand)

36
Q

What is graphesthesia?

A

Trace/write a number on a hand with the fingers, if the patient can’t tell you the number, there is a problem with the cortex
