Study Notes
Muscles of the Body
-
Need to Know: Adductors: Adduct femur; Hamstrings: Flex leg at knee, assist hip extension; Quadriceps: Extend knee, flex hip; Sartorius: Flexes knee & hip, laterally rotates femur; Iliotibial Band (ITB): Stabilises knee & hip; Gastrochnmius: Plantar flexion, knee extended; Soleus: Plantar flexion, knee flexed; Tibialis Anterior: Dorsiflexion & inversion; Peroneals: Eversion & plantar flexion
-
Nice to Know: Pubic bone & ischium, medial edge of femur; Ischium & femur, tibia & fibula; Femur & AIIS, tibia
-
Additional Information: Tailors muscle (Not a muscle, an important tendon); Main propelling force for running & walking, use in hill walking
Back and Pelvic Muscles
-
Action: Latissimus Dorsi: Extends, adducts, and medially rotates humerus; Quadratus Lumborum: Extends & laterally flexes trunk; Erector Spinae: Extend trunk when both sides contract; Laterally flex trunk when one side contracts
-
Attachments: Latissimus Dorsi: Iliac crest, T7-S5, humerus; Quadratus Lumborum: Iliac crest, 12th rib, L1-L4; Erector Spinae: Sacrum, all vertebrae, ribs, occipital bone
Buttocks and Leg Muscles
-
Action: Gluteus Maximus: Extends & laterally rotates femur, also extends trunk especially lower back; Gluteus Medius: Abducts & medially rotates femur, also gluteus minimus same attachments & action; Tensor Fascia Latae: Flexes, abducts & medially rotates hip, hip flexor, also flexes trunk; Iliopsoas: Flexes hip
-
Attachments: Gluteus Maximus: Sacrum, ilium & femur; Gluteus Medius: Ilium, greater trochanter; Tensor Fascia Latae: Ilium, greater trochanter; Iliopsoas: Iliac crest, ITB/ L1-L5
Deep Back Muscles
- Note: Widest muscle of the back, which moves the arm; Deep to erector Spinae; Iliocostalis, longissimus, & spinalis; Tight muscle may cause sciatica
- Additional Information: Also includes gluteus minimus showing same attachments and action as medius and Small but important muscles acting together, important for runners.
