In this lab we were supposed to show the bone, joint, muscles, and the neuron. I decided to do the femur, fibula, tibia and the patella.
The supplies I used were construction paper, pipe cleaners, and playdough.
In this picture you see the femur bone with the patella connecting it to the fibula and the tibia.
This picture shows the muscles that are attached the bones. The Quadriceps femoris straightens leg at the knee; raises thigh. The Tibialis anterior turns the foot upward, as when walking on heels. The Extensor digitorum longus raises toes and raises the foot.
The hinge joint is a freely moving joint in which the bones are so articulated as to allow extensive movement in one plane.
These pictures show the neuron with the myelin sheath.
This image is of the sarcomeres contracted it shows how when the mycrofibris of a muscle fiber contracts is shortens them.
The Sarcomeres are in a relaxed state here and not contracted.
