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.
