Leg Muscles

Here I am with another eye bleeding topic; leg muscles.
Anatomy again!

I know I insisted pretty much on anatomy last weeks; but gathering antomy knowledge is not only for avoiding major mistakes in your drawing, it is also for havingfar better results in your human drawing, being able to draw anything from your imagination very detailed or even maybe not that far but being able to see what you should see in your reference photo(s). The more you know anatomy, the more drawing human is easier.

I divided leg as lower and upper parts and avoided strict anterior-medial-posterior-lateral sides; because a posterior muscle can be seen from lateral side too, like posterior muscle biceps femoris.
Also followed a direction from anterior to lateral, from lateral to posterior, then the last part which is medial.

There are some muscles, they are major muscles for me to distinguish, they help me to remember the array, this little technique can help you, too; I colored (only) them reddish; like the one sartorius; I kinda like this one a lot. I don’t know how it sounds but the way that the muscle twirls from upper anterior side over rectus femoris to down medial side of patella ligament is like, so much characteristic for a muscle 😀 The only explanation is I was so much into anatomy lately 😀 I even have another favorites from leg, which are illitobial tract and tibialis anterior.

Another important point, that you should be certainly careful about is that while studying this from different sources and maybe comparing content, it is hard to say what is what sometimes and you can even think there is a mistake in one of the sources possibly; the thing is you should pay attention that which leg’s what side you’re studying, I mean check if it is right or left leg; according to this muscles can be mirrored. It is a source of trap.

P.S.: If you’re not familiar with the words like ‘tarsal, metatarsal, calcaneus, tibia, fibula, femur‘ etc. please visit the previous study called ‘Leg and foot bones’.

anterior and posterior leg muscles

Upper leg (anterior->medial->posterior->lateral)
Vastus lateris; from femur to quadriceps tendon* [vastus lateralis, vastus medialis, vastus intermedius(deep to rectus femoris) and rectus femoris four together are quadriceps muscles*], on the lateral side of the quadriceps, extention of knee joint
Rectus femoris; the muscle in the middle of the quadriceps, in the middle of the front of the tight, quadriceps tendon to patella, flexion the tight at the hip joint and extention of knee joint
Vastus medialis; on the medial side of the quadriceps, extention of the knee
Sartorius is the longest muscle in the body, from anterior superior iliac spine(from pelvis) passes near rectus femoris and vastus medialis, in the upper anterior side of the leg, heads to medial side
Adductor muscles; adductor magnus, adductor brevis, adductor longus, pectineus and gracilis are a group of tight muscles
Gracilis; medial adductor muscle
Semitendinosus; muscle of a back of the tight, one of the three hamstring muscles
Semimembronosus; on the posterior and medial side of the tight, deep to semitendinosus, one of the three hamstring muscles
Biceps femoris; posterior muscle, one of the three hamstring muscles
Iliotibial tract/band; on the lateral side
Tensor fasciae latae; continuous of iliotibial tract and assists pelvis to balance while standing, walking or running

Vastus lateralis (and back to where we started)

Patella (kneecap) makes me think of ‘paella‘, completely out of our topic.
Patellar ligament comes after patella; while muscle attaches to a bone by tendons, bone connects to a bone by ligament.

medial and lateral leg muscles

Lower leg (anterior->medial-> posterior->lateral)
Extensor digitorium longus; from lateral condyle of the tibia between fibula and fibia to middle and (1st, 2nd, 3rd, 4th) distal toe phalanges, extention
Tibialis anterior; from the lateral body of tibia to medial cuneiform and 1st metatarsal bone; inversion; dorsiflexion
Tibia(shinbone); the stronger and larger one of the 2 bones below knee, on the medial side next to the fibula
Soleus; from below of knee to the heel, lies below the gastronemius, superficial from posterior side, plantarflexion
Medial gastrocnemius; from medial condyle of femur to calcaneus (heel bone), plantarflexion of foot, flexion at the knee joint
Lateral gastrocnemius; from lateral condyle of femur to calcaneus, plantarflexion of foot, flexion at the knee joint
Soleus (seen again), gastrocnemius and soleus attacht together to posterior surface of calcaneus with achilles tendon

Fibularis/peroneus longus; from the head of fibula to down and around the lateral malleolus of the ankle, then under the foot to medial cuneiform and the 1st metatarsal [malleolus is the prominence forms by the ends of fibula(lateral side) and tibia(medial side)]
Fibularis/peroneus brevis; from lower body of the fibula to 5th metatarsal

Fibularis/peroneus tertius; from lower distal surface of fibula to 5th metatarsal bone, dorsiflexion, eversion, rotating
Extensor hallucis longus; from middle of fibula’s surface to the big toe’s distal phalange, dorsiflexion of ankle joint
Extensor digitorium longus (and back to where we started)

Now here I have something more; parts of legs, 4 of them with how muscles apply inside the contours.

leg muscles leg drawings.jpgI noted down what leg they are(right or left), their sides as lateral-medial and names of muscles.

Anatomy is a huge and very complicated topic. In the next months I’m hoping that I will be sharing supportive anotomical drawings, to keep it fresh. But right now we are going to have a break of it(yay!). It will be better to digest what we have leart so far and time to practice it; sketch it from memory, write the names of bones and muscles, find the missing names, find mistakes, correct them as much as possible. And in the end repeat the process from time to time until you are satisfied.
I know how all of these names look, but it is not that hard as you think. It gets easier the more you practice. Practice is important. Yet, It feels cool(:D) when you learn anatomy. What we have here is superficial part of it, which is what interests us.

Take your time, take it easy. Practice, practice, practice.
Happy sketches! ^^
