tibialis anterior
Tibialis anterior
This long ridge of the tibia is called the anterior crest or anterior border. See link below:
The anterior tibialis muscle is located in the front part of the lower leg. It runs along the shin bone (tibia) and is responsible for dorsiflexion of the foot, which means it helps lift the foot upwards towards the shin.
All the bones in the human leg are weight bearing except the fibula.
The fibula is sometimes referred to as the calf bone because it runs parallel to the tibia in the lower leg, giving shape and structure to the calf muscle. However, the fibula plays a minimal role in weight-bearing compared to the tibia.
The tibia is part of the lower leg. Below your thigh, (femur), and your knee,(patella), are two long bones, the tibia and the fibula. They are easy to tell apart in that the tibia is larger then the fibula. "The shin bone", is your tibia. It is slightly stronger than the fibula.
The anterior border is the easily felt and very prominent, boney ridge that runs vertically along the front of the tibia (shin).
The sartorius muscle attaches to the anterior superior iliac spine (ASIS) of the pelvis at its origin and inserts onto the medial aspect of the tibia at the pes anserinus. This muscle runs diagonally across the thigh, contributing to hip and knee movements.
Fibula-- someone answered tibia on a previous question and that answer is incorrect
The biceps femoris runs down the outside of the leg and inserts on the head of the fibula, the semitendinosus runs down the inside of the leg and inserts on the front of the tibia and the semimembranosus runs down the inside of the leg underneath the semitendinosus and inserts on the front of the tibia as well.
Of the two bones in the lower human leg, the tibia is the longer and the fibula is narrower. The tibia is the main weight-bearing bone and the fibula allows the rotation of the foot. The tibia is also called the shin bone. If you are eating a chicken drumstick, the tibia is what you are holding. The fibula is that little splinter of a bone that runs about 2/3 of the way down. Tibia is Latin for "flute" because long hollow bird tibias could be carved into flutes...you might be able to make a piccolo out of a chicken tibia.
The sartorius muscle is considered the longest muscle in the human body. It runs from the hip to the inner side of the knee. The gracilis muscle, located in the inner thigh, is one of the most slender muscles in the body.
