    Study Notes

    Tibial Tuberosity and Quadriceps Femoris

    • The tibial tuberosity serves as an attachment point for the quadriceps femoris tendon.

    Weight-Bearing Bone

    • The tibia is considered the only weight-bearing bone of the crural region.

    Lateral Stability

    • The fibula provides lateral stability on the lateral side of the ankle.

    Distal Tibiofibular Joint

    • The fibula articulates with the tibia to form the distal tibiofibular joint.

    Interosseous Membrane

    • The interosseous membrane connecting the tibia and fibula provides stability and allows for limited movement between the two bones.

    Heel Bone

    • The calcaneus forms the largest and strongest heel bone in the foot.

    Ankle Anatomy

    • The talus bone articulates with both the tibia and fibula.
    • The medial malleolus plays a crucial role in ankle anatomy.

    Muscles

    • The gluteus maximus is considered the most powerful muscle in the body.
    • The hamstring group, specifically the semitendinosus, flexes the thigh.
    • The sartorius muscle is known as the tailor muscle.
    • The rectus femoris is part of both the quadriceps femoris group and flexes the thigh at the hip.
    • The gastrocnemius muscle extends the leg at the knee joint among the posterior flexor muscles.
    • The tensor fasciae latae does NOT belong to the quadriceps femoris group.
    • The quadriceps femoris muscle extends the knee when standing up or kicking a ball.
    • The iliopsoas muscle acts with the iliopsoas to flex the hip while running.
    • The gastrocnemius muscle plantar flexes the foot at the ankle joint and is considered a weak leg flexor.
    • The hamstrings flex the leg at the knee and plantar flex the foot at the ankle joint.

    Nerves

    • The common peroneal nerve arises from the sacral plexus and innervates the anterior and lateral leg, as well as the dorsum of the foot.
    • The tibial nerve innervates the posterior surface of the thigh and leg.
    • The tibial nerve primarily innervates the Flexor hallicus longus muscle.
    • The popliteus muscle medially rotates the tibia to unlock the knee.
    • The sacral plexus supplies the anterior and posterior regions of the thigh and leg.
    • The deep peroneal nerve innervates both the dorsum and plantar aspects of the foot.
    • The superior gluteal nerve innervates the superior gluteal region.
    • The tibialis posterior muscle primarily inverts and supports the arch of the foot.

    Foot Anatomy

    • The cuboid bone articulates with the calcaneus and navicular bones in the foot.
    • The short head of the Biceps Femoris muscle originates from the linea aspera.
    • The medial longitudinal arch of the foot extends to the first metatarsal bone.
    • The hamstrings commonly flex the leg at the knee joint and extend the thigh at the hip.
    • The ankle joint, specifically the calcaneus and talus bones, helps bear the weight of the body.
    • The hallux is another term for the big toe in foot anatomy.
    • The Semimembranosus muscle inserts into the medial condyle of the tibia.
    • Metatarsals I-III articulate with the cuneiform bones.
    • The tibialis anterior muscle is responsible for dorsiflexing and inverting the foot.
    • Excessive arch can lead to foot pathologies, such as pes cavus.
    • The Fibularis longus and brevis muscles evert and dorsiflex the foot.
    • The extensor digitorum longus muscle extends toes 2-5 and dorsiflexes the foot at the ankle joint.
    • The long head of the Biceps Femoris muscle originates from the ischial tuberosity.
