NUR 0012 Lecture 23 Ch. 10 Muscular System Cont.: Muscles of Lower Limb Acting on Hip and KneeOutline of Last LectureI. Ch. 10 muscular system cont.A. Shoulder muscles: axial, scapular, and rotator cuffsB. Arm muscles: anterior and posteriorC. Forearm muscles: flexors, extensors, pronators, supinator, and thumb movementsOutline of Current LectureI. Ch. 10 muscular system cont.A. Muscles of lower limb acting on the hipB. Muscles of lower limb acting on the leg at the kneeCurrent LectureI. Ch. 10 muscular system cont. A. Muscles of lower limb acting on the hip1. Anterior: hip flexorsa. Iliopsoas: 2 muscles working together (Psoas major and Iliacus) to flex trunk and hip2. Lateral and posterior: hip extensors and rotatorsa. Gluteus maximus: strongest hip extensor, laterally rotatesb. Gluteus medius (minimus): abducts hip, medially rotates hipc. Tensor fascia latae: abducts and medially rotates hip, steadies the thigh3. Lateral hip rotators: all act laterally to rotate thigh, analogous to rotator cuff of upper arma. Superior and inferior gemellib. Obturator externus and internusc. Piriformisd. Quadratus femorisThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.4. Medial: hip adductors, all run from pubis to medial side of femura. Adductor longus, magnus, and brevis: adduct hip and medially rotate itb. Gracilis: adduct thigh and medially rotate leg at kneeB. Muscles of lower limb acting primarily on leg at knee1. Sartorius: unique muscle that flexes and rotates hip, and flexes the knee (tailor’s muscle)2. Anterior: knee extensorsa. Rectus femoris: quadriceps group, extends knee and flexes hip, since it crosses two joints it actually flexes hip as well as extends itb. Vastus lateralis, medialis, intermedius (quad group): extends knee3. Posterior: knee flexors, will continue next
