WHAT VALVES IN THE BLADDER ARE A PROTECTIVE FACTOR FOR UPPER UTIS
VESICOUTERIC VALVES
WHAT EPITHELIUM IS THE BLADDER LINED WITH
TRANSITIONAL EPITHELIUM
WHAT MAKES TRANSITIONAL EPITHELIUM IMPERMEABLE
VERY TIGHT JUNCTIONS BETWEEN THE CELLS SO THAT EVEN WITH STRETCH THEY ARE IMPERMEABLE
WHAT IS THE SMOOTH MM OF THE BLADDER REFERRED TO AS
DETRUSOR MM
WHAT ARE THE THREE LAYERS OF MUSCULARIS IN THE BLADDER
INNER = LONGITUDINAL MIDDLE = CIRCULAR OUTER = LONGITUDINAL
WHAT IS THE ADVENTITIA OF THE BLADDER
VARIABLE AMOUNTS OF PERIVISCERAL FAT
WHERE IS TRANSITIONAL EPITHELIUM FOUND
URETERS, BLADDER, RENAL PELVIS
HOW DOES THE APPEARANCE OF TRANSITIONAL EPITHELIUM CHANGE WITH BLADDER DISTENSION
NORMAL = CUBOIDAL DISTENDED = LOOKS STRATIFIED SQUAMOUS
WHAT ARE THE TWO FUNCTIONS OF THE MALE URETHRA
URINARY AND REPRODUCTIVE
WHAT STRUCTURES DOES THE MALE URETHRA PASS THROUGH
PROSTATE AND CORPUS SPONGIOSUM
WHAT ARE THE 4 PARTS OF THE MALE URETHRA
PREPROSTATIS POSTPROSTATIS INTERMEDIATE SPONGY
WHAT IS THE FUNCTION OF THE FEMALE URETHRA
URINARY
In females MOST OF THE URTHRA IS EMBEDDED WITHIN THE
ANTERIOR VAGINAL WALL
IS THE URETHRA COLLAPSED WHEN NOT URINATING
YES
IS THE INTERNAL URETHRAL SPHINCTER INVOLUNTARY OR VOLUNTARY
INVOLUNTARY
WHAT DIVISION OF THE NS KEEPS THE IUS CONTRACTED
SNS
WHAT DIVISION OF THE NS RELAXES THE IUS
PNS
IS CONTROL OF THE EXTERNAL URETHRAL SPHINCTER INVOLUNTARY OR VOLUNTARY
VOLUNTARY
WHAT INNERVATES THE EXTERNAL URETHRAL SPHINCTER
PUDENDAL NERVE S2-4
WHAT MM ALSO CONTRIBUTE TO URINARY CONTINENCE
LEVATOR ANI MM OF THE PELVIC FLOOR
WHAT ARE THE THREE EVENTS OF MICTURITION
CONTRACTION OF DETRUSOR MM, RELAXATION OF THE IUS, RELAXATION OF THE EUS
IN INFANTS WHAT MEDIATES URINATION
SIMPLE SPINAL REFLEX (INVOLUNTARY)
WHAT CIRCUTS FROM HIGHER BRAIN CENTRES MATURE ENOUGH TO OVERRIDE REFLEXIVE URINATION
DESCENDING CIRCUTS
AT AGE 2-3, DESCENDING CIRCUTS MATURE TO ALLOW FOR
VOLUNTARY CONTROL TO OVERRIDE REFLEXIVE URINATION
