Muscle Flash Cards Lower Limb Prepared by: Feng-Yen Li Supervised by: Kim Topp
Introduction Useful tips for usage: 1.These flashcards are meant to help you learn the movements of the muscles. They are most useful when you see how the movements makes sense in relation to the origin and insertion points. 2.For exam purposes, you only need to know (memorize) the action, innervation, and arterial supply of each muscle. But Italicized = do not need to know for exam. 3.The purple slides are summary slides (if applicable) of subsequent muscles. Use these to learn the common properties of groups of muscles. 4.Information about each muscle is also listed in the notes section under each picture slide. 5.The titles in table of contents are hyperlinked its slide, but you need to go into presentation mode to use the hyperlinks.
Acknowledgements Special thanks go to: Kim Topp for reviewing all the slides for validity. Daniel Orjuela and Paul Teresi for taking the cadaver pictures. UCSF 2006 Curriculum Ambassador Program for funding this project. UCSF 2006 Curriculum Ambassadors and Mentors for offering useful suggestions. Members of the UCSF Class of 2009 for inspiring and supporting me to do this project.
Useful Websites Here are other useful sites to learn the muscles: http://www.rad.washington.edu/atlas/http://www.rad.washington.edu/atlas/ (shows each muscle in isolation) http://www.ithaca.edu/faculty/lahr/LE2000/LE_index. htmlhttp://www.ithaca.edu/faculty/lahr/LE2000/LE_index. html (has many nicely labeled cadaver pictures)
Table of Contents Anterior Thigh Sartorius Quadriceps Medial Thigh Adductors Gracillus Posterior Thigh Semitendinosus Semimembranosus Long Head of Biceps Femoris Anterior Leg Tibialis Anterior Extensor Hallucis Longus Extensor Digitorum Longus Lateral Leg Fibularis Longus Fibularis Brevis Posterior Leg Superficial Muscles Gastrocnemius Soleus Deep Muscles Flexor Digitorum Longus Flexor Hallucis Longus Tibialis Posterior
Anterior Thigh Action Extend leg at knee joint (except sartorius) Innervation Femoral nerve Artery Supply femoral artery
Sartorius Origin Anterior superior iliac spine Insertion Medial/anterior tibia (pes anserine) Action Flexes and laterally rotates the hip joint and flexes the knee Innervation Femoral nerve Arterial Supply Muscular branches of the femoral artery
Gracilis Origin Inferior ramus of pubis Insertion Medial surface of tibial shaft (pes anserine) Action Flexes the knee, adducts the thigh, and helps to medially rotate the tibia on the femur Innervation Obturator nerve Arterial Supply Obturator artery, medial circumflex femoral artery, and muscular branches of profunda femoris artery
Posterior Thigh (Hamstring Muscles) Action Flex the leg at knee joint, extend thigh Innervation Sciatic nerve
Long Head of Biceps Femoris Origin Ischial tuberosity Insertion Fibular head Action Flexes the knee, extends thigh, rotates the tibia laterally Innervation Sciatic nerve Arterial Supply Perforating branches of profunda femoris artery, inferior gluteal artery, and the superior muscular branches of popliteal artery
Anterior Leg Action Dorsiflex the foot and extend the toes Innervation Deep fibular nerve (deep peroneal) Artery Supply Anterior tibial artery
Extensor Hallucis Longus Origin Fibula Insertion Distal phalanx of great toe Action Extends great toe and dorsiflexes ankle Innervation Deep fibular/peroneal nerve (L4, L5, S1) Arterial Supply Anterior tibial artery
Flexor Hallucis Longus Origin Fibula Insertion Plantar surface of base of distal phalanx of great toe Action Flexes great toe; helps in plantar flexion of ankle Innervation Tibial nerve (S2, S3) Arterial Supply Muscular branch of peroneal and posterior tibial artery
Tibialis Posterior Origin Fibula and Tibia Insertion Various locations at the base of foot Action Principal invertor of foot; adducts foot, plantar flexes ankle Innervation Tibial nerve (L4, L5) Arterial Supply Muscular branches of sural, peroneal and posterior tibial arteries
