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 Boundaries Content Feature

``` B/w ischium and rectum Boundaries A:perineal membrane , supf transverse perineal muscle P: glut. Max ,sacrotuberpus lig Lat: obturator internus , ischium bone Med: leavtor ani ``` Ine side Connects with other : horseshoe abscess

Ms attachments at ischial tuberosity

Semitendenosus Semi membranosus Adductor magnus Biceps femoris

Structures piercing sacro tuberous ligament

Coocygeal plexus Inferior gluteal nerve (coccygeal branches ) Perforating cutaneous nerve Inferior gluteal artery

Cremaster muscle nerve supply

Ms of scrotum Motor- genital branch of genito femoral nerve Sensory :medial: ilioinguinal Lateral femorAl br of genitofemoral nerve

Contents of spermatic cord

3 arteries : cremateric ,artery to ductus deferens ,testicular 3 nerves : genitofemoral ,autonomic ,visceral afferent nerves 3 other pampiniform plexus ,vas deferens ,lymphatics Ilioinguinal nerve is OUTSIDE IT

Lymphatics of female reproductive sys

Fundus - pre para aortic LN Isthmus - round ligament -> superficial inguinal nodes Mid uterus - ext iliac Lower uterus (cervix ) - everywhere except inguinal

Waldeyers fascia

Presacral fascia ( behind rectum )

Denovilliers fascia

Rectovesical fascia | Between rectum and prostate

Anteversion angle

90 B/w vagina and cervix Maintained by round ligament

Deep dorsal vein of penis

Lies medual to dorsal artey of penis on dorsum of penis Lies deep to bucks fascia Drains into prostatic plexus of veins And is compressed against underlying deep fascia of penis during erection

``` Scrotum Nerve supply Arterial Venous Lymphatic ```

Ilioinguinal and genitofemoral A: posterior scrotal branches of internal pudendal , anterior scrotal of external pudendal V: posterior scrotal into internal pudendal vein L: superficial inguinal ln

Bleeding vessels in haemorrhoids is

Superior rectal vein (branch of inferior mesenteric vein)
