Anatomy of Urinary Incontinence and Renal Pain Flashcards
What conveys sensory nerve fibres from body wall to CNS?
somatic sensory
What conveys sensory nerve fibres from organs to CNS?
visceral afferent
What conveys motor from CNS to body wall?
somatic motor
What conveys motor from CNS to organs?
parasympathetic or sympathetic
Sympathetic nerve fibres leave the CNS only within the spinal nerves between spinal cord levels of what, and what is this called?
T1-L2 (“thoracolumbar outflow”)
Which cranial nerves are parasympathetic?
III, VII, IX & X
Parasympathetic nerve fibres which innervate the kidneys & ureter are carried within which nerves?
vagus nerves
Parasympathetic nerve fibres which innervate the bladder are carried within which nerves?
the pelvic splanchnic nerves
Where is bladder pain normally felt?
suprapubic region (midline)
Pain from a calculus obstructing the ureter can often be felt where?
radiating from “loin to groin”, on the affected side
Pain from the kidney itself (e.g. in acute hydronephrosis) is felt where?
In the “loin”: posterior aspect of the flank region, on the affected side
Pain from the (perineal part of the) urethra is usually felt where?
localized to perineum
Visceral afferents from the KIDNEYS
enter the spinal cord approx. between which vertebra levels?
T11 and L1
Give 5 differentials for loin pain.
skin origin (e.g. herpes zoster) muscular vertebrae spinal nerve root compression lower lobe pneumonia
Visceral afferents from the URETER
enter the spinal cord approx. between which vertebra levels?
T11 and L2
Differentials of groin pain?
hernias (inguinal or femoral)
lymphadenopathy
testicular pathology
Visceral afferents from the BLADDER
enter the spinal cord approx. between which vertebra levels?
T11 and L2
How Do Visceral Afferent & Somatic Sensory Nerve Fibres get from the Urethra to the CNS?
visceral afferents enter back at spinal cords levels S2,S3,S4
