22
Q

When performing the corneal blink reflex what is the expected outcome?

A

blinking of both eyes when the cornea of one eye is touched with a cotton wisp

23
Q

what superficial reflex is associated with stimulation from the sternum towards the umbilicus?

A

epigastric reflex

24
Q

What superficial reflex is associated with stimulation from the upper abs (down and out, out and in direction)?

A

upper abdominal reflex

25
Q

What superficial reflex is associated with stimulating the skin at the level of the umbilicus from out to in, and vertical?

A

Middle abdominal reflex

26
Q

What superficail reflex involves stimulating the skin of the lower abs from an out to in direction?

A

lower abdominal reflex

27
Q

What superficial reflex should result in the umbilicus moving up and out?

A

upper abdominal reflex

28
Q

What superficial reflex should result in moving the umbilicus laterally?

A

middle abdominal reflex

29
Q

what superficial reflex should result in moving the umbilicus down and out?

A

lower abdominal reflex

30
Q

When might the cremasteric reflex be abscent?

A
  1. elderly
  2. hydrocele
  3. varicocele
31
Q

How do you perform the test of the plantar superficial reflex?

A

stroke the plantar surface of the foot from heel to metatarsals to the big toe (in a 7 shape)

32
Q

What is the normal elicited response to the plantar reflex?

A

plantar flexion of toes and foot

33
Q

what is the abnormal response to the plantar reflex?

A

dorsiflexion of great toe and flaring of the other toes

34
Q

What is the normal elicited response to the anal reflex?

A

contracture of the external sphincter

35
Q

what could a loss of external sphincter contracture mean?

A

cauda equina syndrome

36
Q

If cauda equina syndrome or lesion of is suspected what should you do to determine the diagnosis;

A

MRI of thoracics b/c no cord in the lumbars; if there is no lesion in the thoracics do cervical MRI

37
Q

If a decrease in external sphincter contraction is unilateral vs symmetrical what should you think in terms of diagnosis?

A

unilateral = cord lesion

symmetrical = brain lesion

38
Q

The babinski response is revealed with which superficial reflex test?

A

plantar
