Study Notes
- The video is sponsored by Kenhub and is a lesson on remembering the muscles of the lower limbs.
- The video is divided into smaller sections for beginners.
- The first section covers muscles of the hip region.
- The iliopsoas muscle is a hip flexor made up of iliacus and psoas major, originating on the pelvis and vertebral bodies respectively.
- The psoas minor is a smaller muscle that helps flex the spine but is not a hip flexor.
- The gluteus maximus, medius, and minimus are all gluteal muscles that originate on the back side of the ilium and insert on the femur.
- The tensor fasciae latae (TFL) is a hip muscle that shares the iliotibial band with the gluteus maximus.
- The piriformis muscle is located directly inferior to the glute minimus and is the muscle stretched in pigeon pose.
- There are several other smaller muscles in the hip region, including the gemellus superior and obturator internus.
- The sartorius muscle is the longest muscle in the body and goes from the pelvis to the tibia, allowing for hip flexion, external rotation, and abduction.
- The quadriceps are a group of four muscles that extend the knee and insert on a common patellar tendon.
- The hamstrings consist of three muscles: biceps femoris, semitendinosus, and semimembranosus, which originate on the pelvis and femur respectively.
- The adductor group is made up of five muscles that work together to adduct the thigh: adductor magnus, longus, brevis, gracilis, and pectineus.
- The anterior muscles of the lower leg include the tibialis anterior, extensor digitorum longus, and extensor hallucis longus, which extend the digits and big toe respectively.
- The fibularis tertius is a small muscle that helps dorsiflex the foot.
- The posterior muscles of the lower leg include the gastrocnemius, soleus, and popliteus, which help with plantar flexion, support the arch, and unlock the knee respectively.
- The tarsal tunnel contains several muscles that start near the knee and send tendons down the leg and under the foot, including the tibialis posterior, flexor digitorum longus, and flexor hallucis longus.
- The foot has two arches, longitudinal and transverse, and muscles that support each arch include the extensor digitorum brevis, extensor hallucis brevis, abductor hallucis, and abductor digiti minimi.
- The video mentions Kenhub as a useful resource for learning anatomy, offering a library of articles, illustrations, and quizzes.

Description
Learn about the muscles of the lower limb, including those in the hip region and lower leg, with a focus on their origins, insertions, and actions. This lesson is suitable for beginners as it covers each muscle in detail, including the iliopsoas, gluteal muscles, quadriceps, hamstrings, adductor group, and muscles of the lower leg and foot.
