The arcane superficial reflex!!!
“response to stimulation of either the skin or mucous membrane”
- polysynaptic, slow, longer latency, easily fatigable
- abolished by pyramidal tract lesions

Palmar reflex
“stroking the palm of the hand is followed by flexion of fingers or closing of the hand”
youtube.com via: Dr. Sourya Acharya
2/

Scapular reflex
“scratching the skin over the scapula/interscapular space causes contraction of scapular muscles”
youtube.com via: Department of Physiology
3/

Cremasteric reflex
“stroking the skin on inner aspect of the thigh cause contraction of the cremasteric muscle (elevate homolateral testicle)”
youtube.com via: Clinical Examination Videos
4/

Cremasteric reflex ≠ Dartos reflex
Dartos reflex is a sympathetically mediated reflex
“evoked ipsilaterally by local cold on the scrotum, and produces a slow, writhing, vermicular contraction of the scrotal skin together with testis elevation”
5/

Gluteal reflex
“contraction of gluteal muscles due to stroking the skin over the buttocks”
youtube.com via: PalmerNMS
6/

Plantar reflex
“stroking plantar surface of the foot from the heel forward is normally followed by plantar flexion of the foot and toes”
youtube.com via: onlinemedicalvideo
7/

Plantar reflex ≠ extrapyramidal plantar flexion
Extrapyramidal plantar flexion
“tonic plantar reflex with slow, prolonged contraction”
- frontal lobe
- extrapyramidal diseases
8/

Anal reflex (anal wink)
“contraction of external sphincter in response to stroking the skin in the perianal region”
youtube.com via: Clinical Examination Videos
9/

Bulbocavernosus reflex
“stimulus delivered to glans penis/clitoris lead to contraction of the anal sphincter”
youtube.com via: Dr. Ebraheim
10/

Abdominal reflex
“stroke of anterior abdominal wall lead to contraction of the abdominal muscles”
Can be divided into:
- Epigastric reflex
- Umbilical reflex (upper/lower abdominal reflexes)
11/

Epigastric reflex
“elicited by a stimulus moving from the xiphoid toward the umbilicus; there is usually no retraction or movement of the umbilicus”
youtube.com via: PalmerNMS
12/

Umbilical reflexes
“light stroking in each quadrant elicits the response, pulling the umbilicus in the direction of the stimulus”
youtube.com via: Clinical examination videos
13/

Umbilicus is T10
‘T10 for belly but-ten’
(upper) supraumbilical reflexes -> T7 – T10
(lower) infraumbilical reflexes -> T10 – upper lumbar segments
14/

Bechterew’s hypogastric reflex
“stroking the skin on the inner surface of the thigh causes contraction of the homolateral lower abdominal muscles”
15/

Dissociation of the abdominal reflexes
“absent superficial and exaggerated deep reflexes”
- pyramidal lesion
- affects first the lower quadrant
- in scoliosis, it suggests syringomyelia

Beevor's sign
“movement of umbilicus in supine attempting to flex the head”
- classified by some as part of cutaneous investigation
- weakness of upper part of rectus abdominis
- spinal lesions and myopathies
