LS plexus, LL arteries, ant-med thigh, hip muscles

nerve roots + region/action for compartments of lower limb

*table summary of drawing + actions

gluteal region action + innervation

arteries of lower limb

-external iliac → inguinal l → femoral (ant thight) → deep femoral (post thigh) + popliteal a (adductor hiatus, in adductor magnus)

-internal iliac → obturator int (med thigh)

-popliteal → tibial → ant (ant leg) and post (post leg) tibial a

-post tibial a → fibular a (lat post leg and lat leg, though not actually in lateral compartment?)

foot arteries

Dorsalis pedis

-Distal to extensor retinaculum

-Terminal branch of anterior tibial a.

Dorsal pedis → Arcuate a.

-Gives off dorsal metatarsal aa.

Plantar

-post tibial → lat and medial plantar arteries

table: blood supply + innervation lower limb

identification: ant thigh superficial

identification: ant thigh deep

Iliopsoas parts

-combine past inguinal ligament

-action=flexion of hip and trunk (depends on position/other muscles activated/if fixed on ground)

*Psoas major: last TV and all LV

*Ilioposas: postural muscle

quadriceps muscel tabel

“knee cap”

platella

-largest sesamoid bone in body=lives in a tendon

-”patellar ligament” below bc bone → bone

identificatin: medial thigh muscles superficial

identification: medial thigh muscles deep

pes anserinus

-multiple tendons insert; “foot of goose”

-unique in that the 3 muscles of 3 diffferent: compartments, actions, and innervations

• Sartorius: femoral n; adduct and LR

• Gracilis: obt n; adduct

• ST: tibial n; ext hip and flex knee

adductor brevis and obturator nerve

adductor magnus: 2 parts

-Adductor portion: Originates from Inferior pubic ramus; Insertion=Linea aspera; obturator n

-Hamstring portion: Originates from ischial tuberosity; Insertion= Adductor tubercle; tibial n

• forms adductor hiatus (where femoral a → popliteal a)

adductor hiatus

femoral a → popliteal a

femoral triangle

-3 Boundaries: Inguinal l., Sartorius, Adductor longus

*can get a femoral hernia here; IL is most inf part of abdominal wall

Contents from lateral to medial: “NAVL”

1. Femoral n. (*broom apperance)

2. Femoral a.

3. Femoral v.

4. Lymph nodes (superficial inguinal)

deep femoral artery

-femoral (ant thigh) → deep femoral (post thigh)

Hip

-2 bony components

-type of joint

-actions

-Head of femur + Acetabulum of os coxa (innominate)

-ball and socket

-Flexion; Extension; Abduction; Adduction; Medial Rotation; Lateral Rotation; Circumduction (A combination of the above)
