Evertors -
Peroneus longus
peroneus brevis
Posterior compt of leg
Flexors of ankle : tibial nerve Gastronemeius Soleus Plantaris Deep muscle flexor TDH
Foot eversion occur at ? By? Nerve?
At subtalar joint
By peroneus longus brevis tertius
Superficial peroneal nerve
Foot inversion
Tibialis anterior and posterior
Deltoid ligament (all prefix tibia)
Anterior tibiotalar
Posterior tibiotalar
Tibiocalcaneal
Tibionavicular
Lateral longitudnal joint is contributed by
Calcaeus Cuboid Calcaneocuboid joint navicular ( medial bone ) Meta tarsal 4,5
Medial longitudnal joint is contributed by
Calcaneus Talus cuneiform Navicular Medial metatarals(1,2,3 )
Forced inversion of foot results in
Calcaneofibular ligament
Anterior talofibular ligament
Structures passing through greater and lesser sciatc foramen
(PIN)
Pudendal nerve
Internal pudendal vessels
Nerve to obturator internus
Spring ligament
Aka calcaneonavicular ligament
Superior , medial, lateral,plantar calcaneonavicular
Sacrotuberous lig is pierced by
Coccygeal branches of inferior gluteal artery
Perforating cutaneous nerve s2,3
Filaments of coccygeal plexus
Nerve of perineum
Pudendal nerve
Supplies external urethral sphincter
Bph in which lobe
Median
Parts of urethra
Prostatic
Bulbar
Membraous
Penile (spongy)
Pelvic diaphragm is contributed by
Levator ani (Pubococcygeus ,iliococcygeus) Ischiococcygeus
Urogenital diaphragm ms.
Sphincter urethra
Deep transverse perineal muscles
Layers of penis
Skin
superficial fascia
Deep(bucks fascia)
Tunica albuginea
Perineal nerve course
Formed infront of sacrum
Leaves pelvis through greater sciatic notch to enter gluteal region
Hooks behind ishial spine in gluteal region
enters pudendal canal by passing through lesser sciatic notch
Ischiorectal fossa
