Inferior Tibiofibular Joint


We just learned about the Superior Tibiofibular Ligaments.

Another piece of connective tissue is the Inferior Tibiofibular Joint.

This is down by the ankle, connecting the tibia and fibula together at the bottom.
There are 3 ligaments in total. Anterior for the front side, posterior for the back side, and an interosseous membrane in the middle.

Superior Tibiofibular Ligaments


We just learned about the Patellar Ligament.

Another set of connective tissue is the Superior Tibiofibular Ligaments.

These are the ligaments up by the knee that connect the tibia (shin bone) to the fibula, the smaller bone in the lower leg.

There are two ligaments that tie the tops of the tibia and fibula together.
They are called the anterior (front) of the head of the fibula, and the posterior (back) of the head of the fibula.
The two bones are right next to each other, and at the top there is some connective tissue almost glueing them together.

Patellar Ligament


We just learned about the Medial and Lateral Meniscus.

Another piece of connective tissue is the Patellar Ligament.

This is the ligament that connects the kneecap to the shin bone.
The kneecap is called the patella, and the shin bone is called the tibia.

Medial and Lateral Meniscus


We just learned about the Knee Ligaments.

Another important connective tissue is the meniscus in the knee.

When you have more than one meniscus, it is called menisci.
The meniscus is like the rubber padding on your tibia where your fibula touches so it does not hit the other bone.

The two menisci in the knee are the medial and lateral meniscus.
Medial means closer to the middle of the body, and lateral means further from the middle of the body.
So the medial meniscus is on the inside part of your leg, and the lateral meniscus is on the outside part of your leg.

Knee Ligaments


We just learned about the Hip & Femur Ligaments.

Another set of ligaments are the Knee Ligaments.

There are four main ligaments that connect the femur bone in the thigh, to the tibia and fibula bones of the lower leg.

The Anterior Cruciate Ligament (ACL) connects the back of the femur to the front of the tiba. It helps keep the knee from twisting.
The Posterior Cruciate Ligament (PCL) connects the front of the femur to the back of the tibia.
The Medial Cruciate Ligament (MCL) connects the inside of the femur to the inside of the tibia.
The Lateral Cruciate Ligament (LCL) connects the outside of the femur to the fibula.

Hip & Femur Ligaments


We just learned about the Phalangeal Ligaments.

Another ligament connects the Hip to the Femur.

There are a few different ligaments, tied to the femur from different parts of the hip: The ischiofemoral, pubofemoral and iliofemoral ligaments.

The iliofemoral connecting the upper part of the hip to the femur is the strongest ligament in the whole body, and can support over 700 pounds of weight!

Femoral Vein


We just learned about the Popliteal Vein that brings deoxygenated blood from the knee area back toward the heart.

After the popliteal vein, the blood goes into the femoral vein in the thigh by the femur bone.
This brings blood up through your thigh to your hip area.

Popliteal Vein


We just learned about the Fibular Vein which brings deoxygenated blood from the lower leg up to the upper leg.

Another vein that is in the knee area is called the popliteal vein.

Fibular Vein


We just learned about the tibial vein that brings deoxygenated blood back to the heart.

Another vein in the lower leg right next to the tibial vein is the fibular vein, sometimes called the peroneal vein.

Tibial Veins


We just learned about the small saphenous vein.

Some other veins that brings deoxygenated blood back toward the heart are the tibial veins.

There are two types of tibial veins, anterior and posterior.
The word anterior means in the front, and posterior means in the back.
So the anterior tibial veins are in the front part of your leg by your tibia bone, and the posterior tibial veins are in the back part of your leg by your tibia bone.

Small Saphenous Vein


We just learned about the great saphenous vein that brings deoxygenated blood from the foot up the leg toward the heart.

Another big vein in the foot and leg is the small saphenous vein.

Even though it's name says small, the vein is very big.
It goes from the outside of your foot, then up behind your ankle and up the back of your leg.

Great Saphenous Vein


We just learned about the Dorsal Venous Arch that helps bring deoxygenated blood from the foot toward the heart.

That vein connects to another very big vein called the Great Saphenous Vein.

This vein goes all the way from your foot up your leg to your hip.
It is the longest vein in the human body.

Fibular Arteries


We've learned that oxygenated blood comes through the knee in your popliteal artery, and that there are arteries called tibial arteries that go along your tibia.

The other artery in the back of your lower leg is called your fibula, and there are arteries called Fibular Arteries that go along that bone.

Tibial arteries


We just learned about the popliteal artery that brings oxygenated blood down to through your knee.

After it goes past your knee it splits into two arteries called the tibial arteries.
The anterior tibial artery is in front, and the posterior artery is in back.

Popliteal Artery


After the oxygenated blood comes through the femoral artery, it goes to the popliteal artery.

This artery goes in the middle of your leg, right behind your knee.

Femoral Artery


After the oxygenated blood comes through the abdominal aorta it splits into 10 smaller arteries.

One of those is called the iliac artery which then continues to the femoral artery.
This is a big artery that runs right down the inside of your thigh.

Calf Muscle


We just learned about the Quadriceps muscle.

The muscle on your leg below your knee is called your Triceps Surae muscle,
but most people just call it your Calf Muscle.

You are using your calf muscle when you move your ankle.

Quadriceps


Let's keep learning about the muscles in the human body!

Last time we learned about the gluteus maximus

Next up is the quadriceps.
These are the muscles on your thigh, sometimes just called quads.

You use your quads when you move your upper leg around, or when you bend your knee.

Gluteus maximus



Let's keep learning about the muscles in the human body!

Last time we learned about the rectus abdominis

Next up is the gluteal muscles.
The muscles on your back side (or your butt) are called your gluteal muscles.
There are three muscles there, the gluteus minimus, gluteus medius and gluteus maximus.

Sometimes people call those muscles glutes or just talk about the gluteus maximus
since it's the biggest of the three muscles.

You use those muscles when you lift your leg up and down,
or bend your body backwards.

Tibia & Fibula


We just learned about the femur and patella.

The bones attached below those two are called the tibia and fibula.
patella
(from: wikipedia - fibula)

The tibia is the big one in front, also known as the shin bone.
It's the big flat bone you can feel in the front of your lower leg.
If you feel down around the outside of your ankle you can feel the smaller tibia bone.
