Muscles

Muscles - Lower Limb Sheet. Every lower limb structure on one sheet - muscles, bones, nerves, vessels and the rest, each type in its own table with its own columns.
Muscle	Origin	Insertion	Action	Innervation	Blood supply
Adductor brevis	Anterior pubic body and adjoining inferior ramus	Pectineal line and upper portion of the femoral linea aspera	Draws the thigh toward the midline and contributes to hip flexion	Obturator nerve, usually its anterior division; commonly mapped within L2-L4, with L2-L3 emphasized in some references	Branches of the profunda femoris and obturator arterial systems
Adductor longus	Anterior surface of the pubic body below the crest	Middle portion of the linea aspera on the femur	Adducts the hip and can assist flexion and internal rotation, depending on hip position	Anterior division of the obturator nerve, conventionally L2-L4	Obturator and profunda femoris branches
Adductor magnus	Adductor portion: inferior pubic and ischial rami. Hamstring-like portion: ischial tuberosity	Broad attachment from the gluteal tuberosity region along the linea aspera and medial supracondylar line; vertical portion attaches at the adductor tubercle	Adducts the hip; anterior fibers can aid flexion, while the hamstring-like portion contributes to extension	Classically posterior obturator division (L2-L4) for the adductor portion and tibial division of sciatic, often mapped to L4, for the hamstring-like portion; additional cross-supply occurs	Perforating branches of profunda femoris, with obturator and other regional arterial contributions

Bones

Bones - Lower Limb Sheet. Every lower limb structure on one sheet - muscles, bones, nerves, vessels and the rest, each type in its own table with its own columns.
Bone	Bone type	Key landmarks	Articulations
Calcaneus	Short bone of the tarsus; the largest tarsal	Posterior calcaneal tuberosity; medial sustentaculum tali; lateral fibular trochlea (peroneal tubercle)	Talus above at talocalcaneal articulations and cuboid in front at the calcaneocuboid joint
Femur	Long bone of the thigh	Head and fovea; neck; greater and lesser trochanters; intertrochanteric line and crest; gluteal tuberosity and linea aspera; condyles, epicondyles, adductor tubercle and intercondylar fossa	Acetabulum at the hip; tibia and patella at the knee
Fibula	Long bone on the lateral side of the leg	Proximal head and its apex, narrow neck, shaft and distal lateral malleolus	Tibia at the proximal tibiofibular joint and distal syndesmosis; talus at the ankle

Nerves

Nerves - Lower Limb Sheet. Every lower limb structure on one sheet - muscles, bones, nerves, vessels and the rest, each type in its own table with its own columns.
Nerve	Root value	Course	Motor	Sensory
Common fibular (peroneal) nerve	Usually L4–S2, through the fibular division of the sciatic nerve	Tracks along the medial side of the biceps femoris tendon, curves around the fibular neck and divides deep to fibularis longus into superficial and deep branches	Through terminal branches: lateral and anterior leg muscles and short extensors on the foot dorsum; the more proximal fibular division supplies short-head biceps femoris	Lateral leg through sural cutaneous branches; much of the dorsal foot through superficial and deep fibular branches, with borders varying between people
Deep fibular (peroneal) nerve	Commonly summarized as L4–S1 through the common fibular nerve; published segmental ranges differ	Leaves the proximal lateral leg, passes into the anterior compartment, descends beside the anterior tibial artery and crosses the ankle beneath the extensor retinacula	Tibialis anterior, extensor digitorum longus, extensor hallucis longus and fibularis tertius; extensor digitorum brevis and extensor hallucis brevis in the foot	Usually the facing skin surfaces between the great and second toes dorsally, plus articular and other deep sensory fibers
Femoral nerve	Posterior divisions of the L2–L4 ventral rami in the lumbar plexus	Emerges at the lateral psoas border, runs between psoas and iliacus and passes beneath the inguinal ligament lateral to the femoral artery before branching in the thigh	Quadriceps femoris, sartorius, iliacus and usually pectineus; psoas major receives direct lumbar branches	Anterior and anteromedial thigh through cutaneous branches; medial leg and part of the medial foot through the saphenous nerve; articular branches to hip and knee

Vessels

Vessels - Lower Limb Sheet. Every lower limb structure on one sheet - muscles, bones, nerves, vessels and the rest, each type in its own table with its own columns.
Vessel	Origin	Course	Branches	Supplies	Drains to
Anterior tibial artery¹	A terminal branch of the popliteal artery, usually arising near the lower border of popliteus	Crosses an upper opening in the interosseous membrane, descends in the anterior compartment with the deep fibular nerve, and reaches the front of the ankle	Recurrent branches toward the knee, muscular branches and anterior malleolar branches; continues as dorsalis pedis	Muscles and other tissues of the anterior leg, with onward supply to the dorsal foot	not recorded
Deep femoral (profunda femoris) artery¹	Usually a large posterolateral branch of the femoral artery in the proximal thigh	Turns into the deep thigh and descends behind adductor longus, giving perforators through the adductor tissues toward the posterior compartment	Perforating and muscular branches; usually medial and lateral circumflex femoral arteries, although either circumflex vessel can arise elsewhere	Major supply to thigh muscles across the compartments and contributions to the proximal femur and hip through its branching network	not recorded
Dorsalis pedis artery¹	Usually the continuation of the anterior tibial artery at the ankle joint	Travels over the dorsum toward the proximal first intermetatarsal space, usually lateral to the extensor hallucis longus tendon	Medial and lateral tarsal, first dorsal metatarsal and deep plantar branches; an arcuate artery is common but variable	Dorsal foot tissues and, through connections with the plantar arch, parts of the deep foot	not recorded

Organs

Organs - Lower Limb Sheet. Every lower limb structure on one sheet - muscles, bones, nerves, vessels and the rest, each type in its own table with its own columns.
Organ	Location	Parts	Relations	Blood supply	Innervation	Venous/Lymphatic drainage	Function
Deep inguinal lymph nodes^3,4,5	Deep to the fascia lata along the medial side of the femoral vein, with the uppermost nodal region at the femoral canal	A small group with variable node number and distribution; the node at the upper femoral canal is known as Cloquet's or Rosenmüller's node	not recorded	not recorded	not recorded	Outgoing lymphatic vessels continue toward the external iliac nodes	Immune-cell processing and filtering of lymph arriving from regional tissues before further passage through the pelvic lymphatic system
Popliteal lymph nodes^3,4,5	Embedded in fat within the popliteal fossa, near the popliteal vessels and fascia	Several variably distributed nodes, including a more superficial node near the small saphenous route and deeper nodes beside the main vessels	not recorded	not recorded	not recorded	Mainly ascend beside the femoral vessels toward deep inguinal nodes, with additional connections to superficial inguinal pathways	Filter regional lymph and support immune responses along drainage routes from the knee, leg and foot
Superficial inguinal lymph nodes^3,4,5	Subcutaneous fat of the upper femoral triangle, superficial to the fascia lata and below the inguinal ligament	Traditionally described as an upper group along the inguinal ligament and a lower group along the great saphenous vein; actual numbers and clustering vary	not recorded	not recorded	not recorded	Outgoing channels may reach deep inguinal nodes or continue directly to external iliac nodes	Regional lymph filtering and immune surveillance for tissues of the lower limb, lower trunk and perineum
