encopresis - 🧠 ANSWER ✔✔a disorder characterized by repeated stool
evacuation in inappropriate places in children over the age of four
primary: children who never reached continence
secondary: children who reached continence for at least a year and are
now relapsed
sympathetic nervous system role - 🧠 ANSWER ✔✔*involuntary*
,When the rectum is empty, the SNS inhibits the contraction of the rectal
wall, and contracts the internal anal sphincter (IAS) to prevent leakage
parasympathetic nervous system role - 🧠 ANSWER ✔✔when the rectum is
filled post mass transit, it stretches and the PNS sends information to the
CNS to coordinate bowel elimination. The rectum then contracts in
conjunction with the ENS and the IAS relaxes. Feces then moves down the
anal canal to the external anal sphincter (EAS)
enteric nervous system - 🧠 ANSWER ✔✔The intrinsic nervous system
within the bowel wall. This system responds to a variety of stimuli and
generates peristalsis
rectoanal inhibitory reflex - 🧠 ANSWER ✔✔the involuntary relaxation of the
IAS when the rectum is stretched that allows feces to move down anal
canal
sampling reflex - 🧠 ANSWER ✔✔when rectal contents contact Anoderm
(receptors at distal anal canal) for differentiation
allows squamous epithelium below the Denate Line with sensory receptors
that differentiate between solid, liquid, gaseous rectal contents
,anal wink - 🧠 ANSWER ✔✔with cotton swab, swipe at 5 and 7 o'clock on
the buttocks with the patient in the modified lithotomy position
a focused physical exam that assesses prostate and pelvic muscle control
and verifies function of pudendal nerve
bulbocavernosus reflex - 🧠 ANSWER ✔✔in modified lithotomy position,
squeeze penis glans to verify external anal sphincter wink or flick the
clitoris in females
a focused physical exam that assesses prostate and pelvic muscle control
and verifies function of pudendal nerve
5 factors that promote continence - 🧠 ANSWER ✔✔1: colonic transit, stool
volume, and consistency
2: sensory awareness
3: sphincter competence
4: rectal compliance and capacity
5: extrinsic factors

, secretory diarrhea - 🧠 ANSWER ✔✔The absorptive capacity of the bowel is
overwhelmed by the volume of water and electrolytes that are secreted into
it
osmotic (absorptive) diarrhea - 🧠 ANSWER ✔✔inadequate or reduced
absorption of the bowel
functional (motility) diarrhea - 🧠 ANSWER ✔✔Increased motility results in
decreased contact time of the stool with the lumen and intestinal mucosa
external anal sphincter - 🧠 ANSWER ✔✔composed of smooth muscle that
maintains sphincter tone (contraction) and striated muscle that permits
voluntary control/contractility
parasympathetic nervous system - 🧠 ANSWER ✔✔part of the autonomic
nervous system that acts to promote colonic peristalsis and motility activity
sympathetic nervous system - 🧠 ANSWER ✔✔part of the autonomic
nervous system that acts to reduce intestinal motility and secretions
soluble fiber - 🧠 ANSWER ✔✔foods that contain soluble fiber have the
ability to absorb and retain water
