CHICKEN DISSECTION ANALYSIS

In this dissection we cut apart the thigh, wings, legs, breast to get a closer look at the tendons and the muscles. The Brachioradialis was a muscle that was located in the wing, along with the tendon located in the wing as well, this is what makes the chicken able to fly (open and close their wings). The physical and functional differences in the tendons of the insertion compared to the origin is that the tendon of the insertion has more range of movement compared to the origin. Compared to the lectures that we have leaned on the Muscular System, chickens in a way are similar to the way our muscular system works. They have very similar muscle groups that function similarly to the ways humans do, because that is what allows them to have movement. There breast as well as their gluteus maximus/ gluteus minimus is very prominent, it has a lot of "meat" to it. The quadrieceops, located in the thigh is what helps the chicken with the ability to extend it legs out (the movement of the legs), however the biceps femoris is what actually allows the flexing of the legs. The Semimembranosus also located in the thigh, also the thigh to extend. The chicken have a fair amount of muscle, just like us. In their wing the tricep tendon helped with the flexing of the elbow (we have a cool video of it below). Chickens also have major muscles in their body that are very important (even though all muscles are important). Each section of their body usually has a main muscle component. As so the Peroneus longus- its the primary superfical muscle on the lateral side of its leg (drumstil)(outside of its leg), the Gastrocnemius is also a primary muscle of the dorsal medial side of the drumsitck (back on the inside leg, closer to the midline of the chicken). On the wings the Flexor Carpi Ulnaris is the largest muscle located on the posterior side of the wing (lower part to be exact), this muscle is located away from the thumb of the chicken and it job is the flexing of the chickens hands. A cool fact about chicken and humans and all their muscles is that humans can move their metacarples where a chicken can not do that. 


The chicken muscles and human muscle similarities :

1. chicken and humans have the same type of tissue and cartilage
2. In the chicken wing, chickens have triceps, biceps as do humans (located in the forearm). In the arm both chicken and humans are held together by tendons, which allow us the movement to move are arm in and out. 
3. The bone structure is also similar. Chickens humerus is also attached to the shoulder just like a human and they also have a radius and a ulna.
