Module 4: Hip, Pelvis, Anterior Thigh Flashcards
Movements of Pelvis
Pelvic Tilt (anterior, posterior, lateral)
Functions of Pelvis
Weight bearing, weight transference, protection of organs
Endopelvic Fascia (2 examples)
Tendinous arch of levator ani, tendonous arch of pelvic fascia
Muscles of Levator Ani
Puborectalis, Pubococcygeus, Iliococcygeus
What is the perineal body
CT structure between vagina/penis and anus (anchor point, attachments for muscles)
Action of pelvic floor muscles
Act like a slingshot, lifting anteriorly and superiorly to maintain continence
Function of coccygeus
Draws coccyx anteriorly following defecation/childbirth (parturition)
Superficial Pelvic Floor Muscles (how many? function?)
4 muscles, help with sexual function and continence
What does the Pudendal nerve supply
Motor: Superficial pelvic floor muscles
Sensory: skin of the external genitalia
Psoas Minor Attachments
P: Sides of bodies of T12 and L1 and intervertebral discs
D: Iliopubic eminence and pubis via the pectineal arch
Psoas Minor Action/Nerve Supply
A: Weak trunk flexor/hip stabiliser
NS: Anterior rami of L1,L2
Psoas Major Attachments
P: Transverse process of lumbar vertebrae, sides of bodies of T12-L5/Intervertebral discs of region
D: Lesser trochanter of femur
Psoas Major Action/ Nerve Supply
A: Trunk/Hip flexion
NS: Anterior rami of L1-L3
Iliacus Attachments
P: Upper 2/3 of iliac fossa, ala of sacrum, sacroiliac ligaments
D: Lesser trochanter of femur
Iliacus Action/Nerve supply
A: hip flexion/stabilisation
NS: femoral nerve
Largest nerve of lumbar plexus
Femoral
Formation/path of femoral nerve
Formed within psoas major, emerging low on its lateral border
Passes through gutter between psoas major and iliacus
Pectineus Attachments
P: Superior ramus of pubis
D: Inferior to the lesser trochanter of the femur (on the posterior, superior aspect of the femur)
Pectineus Action/nerve supply
A: Adducts/flexes hip
NS: Femoral Nerve
Sartorius Attachments
P: ASIS
D: Anterior aspect of the medial condyle of the tibia
Sartorius Action/NS
A: Synergist for hip flexion, abduction, lateral rotation, knee flexion
NS: Femoral Nerve
Muscles of the Quadriceps Group
Vastus Lateralis, Intermedius, Medialis, Rectus Femoris
Rectus Femoris Attachments
P: AIIS
D: Quadriceps Tendon - Patella - Patellar Tendon - Tibial Tuberosity
Rectus Femoris Action/NS
A: Hip Flexion/ Knee Extension
NS: Femoral Nerve
Vastus Medialis Attachments
P: Intertrochanteric Line, Medial Lip of linea aspera
D: Quad Tendon - Patella - Patellar Tendon - Tibial Tuberosity
Vastus Medialis Action/NS
A: Knee Extension
NS: Femoral
Vastus Intermedius Attachments
P: Anterior/Lateral surfaces on the shaft of the femur
D: Quad Tendon - Patella - Patellar Tendon - Tibial Tuberosity
Vastus Intermedius Action/NS
A: Knee Extension
NS: Femoral
Vastus Lateralis Attachments
P: Greater trochanter, lateral lip of linea aspera
D: Quad Tendon - Patella - Patellar Tendon - Tibial Tuberosity
Vastus Lateralis Action/NS
A: Knee Extension
NS: Femoral
What is the linea aspera
A vertical crest on the posterior aspect of the femur
Articularis Genu Function
Pulls capsule up in the extension of the knee
How does the femoral nerve enter the femoral triangle
Passes under the inguinal ligament with the femoral artery/vein
What is the largest sensory branch of the femoral nerve
Saphenous Nerve
What does the saphenous nerve supply
Skin to the medial side of the leg below (distal to) the knee
