What is the insertion of the flexor hallucis longus? flexor hallucis longus origin and insertion.
|Origin||tuberosity of the ischium, linea aspera, femur|
|Insertion||the head of the fibula which articulates with the back of the lateral tibial condyle|
|Artery||deep femoral artery, perforating arteries; long head of biceps femoris: perforating branches from profunda femoris artery|
|Origin||Anterior inferior iliac spine, supraacetauluar groove|
|Insertion||Tibial tuberosity (via patellar ligament), patella|
Insertion. Rectus Femoris together with vastus medialis, vastus lateralis and vastus intermedius joins the quadriceps tendon to insert at the patella and tibial tuberosity (via patellar ligament).
|Origin||tuberosity of the ischium, linea aspera|
|Artery||inferior gluteal artery, profunda femoris artery|
|Nerve||sciatic nerve (tibial nerve and common fibular nerve)|
The biceps femoris muscle of the leg derives its name from having two heads of origin, long and short. … The short head originates from the lateral lip of the middle third of the linea aspera and the lateral supracondylar line of the femur. Initially it is aponeurotic.
It is located on the posteromedial side of the thigh deep to Semitendinosus. Its origin is the ischial tuberosity on the inferior pelvis and the insertion is the medial tibial condyle. It’s primary action is knee flexion, hip extension and knee internal rotation.
The insertion for the sartorius muscle is the superior medial aspect of the tibial shaft, near the tibial tubercle. Two other tendons join it at its insertion: the gracilis and semitendinosus, to create the conjoined tendons known as the pes anserinus. At the knee, it acts to flex as well as internally rotate.
But your quadriceps femoris is actually a group of four muscles located at the front of your thigh. In fact, that’s how it got its name. Quadriceps is the Latin word for “four-headed.” Your quadriceps are some of the largest and strongest muscles in your body.
Which of the following best describes the insertion of the extensor digitorum? It indirectly inserts on all digits of the hand.
The quadriceps femoris is a four-headed muscle that inserts onto the tibial tuberosity. It extends the knee, and one head (rectus femoris) flexes the hip.
|Vastus lateralis muscle|
|Insertion||Patella by the Quadriceps tendon and Tibial tuberosity by the Patellar ligament|
|Artery||lateral circumflex femoral artery|
|Actions||Extends and stabilizes knee|
Three muscles run down the back of your leg, from your thigh to your knee — the biceps femoris, semitendinosus, and semimembranosus — and help you bend your knee and extend your hip. As a group, they are known as the hamstring.
The semitendinosus, semimembranosus, and biceps femoris muscles comprise the hamstring muscle group. Beginning at the pelvis and running posteriorly along the length of the femur, the majority muscles within the hamstring complex cross both the femoroacetabular and tibiofemoral joints.
- Biceps femoris.
|Origin||Lateral head: Posterolateral aspect of lateral condyle of the femur Medial head: Posterior surface of medial femoral condyle, popliteal surface of femoral shaft|
|Insertion||Posterior surface of the calcaneus via the calcaneal tendon|

n. A longitudinal ridge running down the posterior surface of the shaft of the femur, affording attachment to various muscles including the vastus medialis, adductor longus, adductor magnus, adductor brevis, vastus lateralis, and short head of the biceps.
The pes anserinus (PA) is composed of the combination of tendinous insertions of the sartorius, gracilis, and semitendinosus muscles. These three muscles attach to the medial side of tibia to generate a shape reminiscent of a goose’s foot, which is the literal meaning of its name.
The semimembranosus inserts at the posterior part of the medial condyle of the tibia.
Two synergistic muscles are associated with the biceps femoris, the semitendinosus and the semimembranosus. Attachments: Originates from the pelvis and femur and attaches to the fibula. Actions: Extends and laterally rotates at the hip, main action is flexing of the lower leg at the knee.

Insertion. The gracilis muscle decends almost vertically down the leg and inserts on the medial tibia at the Pes anserinus. The pes anserinus is also the attachment site of the Sartorius and Semitendinosus.
The sartorius muscle is the longest muscle in the human body. … The sartorius muscle has an oblique course throughout the thigh; it arises from the anterior superior iliac spine, crosses to the medial side of the thigh, and finally inserts to the medial side of the proximal tibia.
The gastrocnemius is a biarticular muscle that acts not only as a plantar flexor, but also as a knee flexor, meaning that it is an antagonist during knee extension. In contrast, the soleus is a monoarticular plantar flexor.
Anatomy. The four quadriceps muscles meet just above the kneecap (patella) to form the quadriceps tendon. The quadriceps tendon attaches the quadriceps muscles to the patella. The patella is attached to the shinbone (tibia) by the patellar tendon.

One muscle that’s named for its origin and insert points is the sternocleidomastoid, which originates at the sternum and clavicle – in this case, ‘cleido-‘ means ‘clavicle’ – and inserts on the mastoid process of the temporal bone.
biceps brachii. Which of the following best describes the insertion of the extensor digitorum? It directly inserts on all digits of the hand except the thumb.
Structure. The tuberosity of the tibia gives attachment to the patellar ligament, which attaches to the patella from where the suprapatellar ligament forms the distal tendon of the quadriceps femoris muscles. The quadriceps muscles consist of the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius …

The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute tibia. It is the second largest bone in the human body next to the femur.

The function of this hamstring is to flex your knee, extend the thigh at your hip and rotate your lower leg from side-to-side when your knee is bent.
The hamstring muscles originate at the ischial tuberosity (or the bone where you sit.) The medial hamstrings, semitendinosus and semimembranosis, attach to the inside of the knee on the tibia (lower leg bone.) This attachment is referred to as the pes enserines.
The hamstrings got their name from the way European butchers would hook through these muscles, behind the knee, to hang up legs of slaughtered pigs in their shops to sell, hence the “ham” and the “stringing”. … The main action of this group of muscles is to extend the hip joint (reference 1).
