Week 5 Flashcards
muscles that attach from axial skeleton to pelvis
psoas major
iliacus
psoas minor
quadratus lumborum
iliopsoas
psaos major
iliacus
muscles that originate within the pelvis
piriformis obturator internus coccygeus levator ani tendinous arch
where does piriformis run
through greater sciatic foramen
where does obturator foramen run
through lesser sciatic foramen
urogenital hiatus
structure through which the urethra and the vagina pass.
muscles that support genitals
ischiocavernosus
bulbospongiosus
superficial transverse perineal muscle
pelvic organs
bladder- anterior
uterus- middle
rectum- posterior
bladder
posterior to pubic bone primarily retroperitoneal receives urine from kidneys via ureters detrusor- smooth muscle expels urine via urethra
where is the detrusor muscle
surrounds bladder
what does the detrusor muscle do
keeps bladder tense
applies pressure trying to push urine out of the bladder
sphincters of the bladder
internal urethral sphincter
external urethral sphincter
which bladder sphincter is involuntary
internal urethral sphincter
which bladder sphincter is voluntary
external urethral sphincter
inside of bladder
ridged,
why is the inside of the bladder ridged
as the bladder fills up it needs to be able to expand, so ridges flatten out providing for an extra increase in volume
rectal sphincters
internal anal sphincter- involuntary
external anal sphincter- voluntary
perineal membrane
between bulbospongiosus, ischiocavernosus and superficial transverse perineal muscles
posterior superficial muscles
gluteus maxiumus- strong extensor
gluteus minimus
posterior deep muscles
obturator internaus obturator externus superior gemellus inferior gemellus quadratus femoris piriformis
important muscle in walking up stairs or hills
gluteus maximus
hamstrings
biceps femoris
semitendinossu
semimembranosus
anterior hip muscles
psoas major sartorius tensor fascia latae quadriceps femoris adductor magnus adductor brevis adductor longus pectineus
iliotibial tract (IT band)
thick band of fascia on the lateral aspect of the knee, extending from the outside of the pelvis, over the hip and knee, and inserting just below the knee
why is the IT band important
keeps fascia of leg nice and taut,
helps with asymmetrical standing- helps keep leg locked in place
quadriceps femoris
vastus lateralis
vastus medialis
vastus intermedius
rectus femoris
hallucis
big toe
tibialis
originates on tibia
fibularis
originates on fibula
lower leg anterior muscles
tibialis anterior extensor digitorum longus extensor hallucis longus fibularis tertius fibularis longus fibularis brevis
lower leg posterior muscles
gastrocnemius poplitues plantaris soleus flexor digitorum longus flexor hallicus longus tibialis posterior
tarsal tunnel
tibialis posterior flexor digitorum longus felxor hallicus longus tibial nerve posterior tibial artery
intrinsic foot muscles
flexor digitorum brevis abductor hallucis abductor digiti minimi flexor hallicus brevis adductor hallucis plantar interossei dorsal interossei
quadratus plantae
attaches the calcaneous to the tendon for flexor digitorum longus
dorsal interossei
abduct toes
palmar interosei
adduct toes
