anal reflex

Anal reflex is a kind of shallow reflection in the human nerve reflex. The person lies flat, and the lower extremity is lifted and straightened. The small needle is crossed in the perineal area, and the external anal sphincter will contract. The examiner uses a cotton swab to gently stroke or use a pin to gently puncture the perineal skin around the anus of the patient. When normal, the anus is contracted immediately.
