Muscular System Proposal
Description:
Our model is showing how the leg functions to kick a ball. As seen, our model has all the muscles acquired and has the femur, tibia, and fibula bone. Where these bones meet, we used a door hinge to act as a joint with modeling clay as cartilage. We made our bones by using wood and our muscles are made up out of surgical tubing.
II. Functions Performed:
The skeleton holds up the rest of the body and provides a case that protects vital organs and tissue. It can also move using muscles attached to the bones that contract and relax using tendons as connectors. The muscles contract and relax to make the leg move. Leg and foot kicks a ball.
III. Materials:
IV. Construction Plan:
V. Principles used:
Biology: Demonstrates the muscular and skeletal systems. Uses joints in the knee and foot, muscles, tendons, ligaments, bones, etc.
Physics: Utilizes levers, tension, and force.
VI. Special needs: tools that can cut/saw through PVC and wood, wood, PVC(along with connectors), motors, POM POMS, surgical tubing
VII. Unresolved issues:
None

III. Materials:
- Surgical tubing (10 ft) (muscles)
- Exercise bands (2 different colors) (ligaments and tendons)
- Staple gun
- Staples (1 box)
- Circular door hinge (1)
- Sandpaper (a lot)
- Modeling Clay (unknown)
- Screws (1 box)
- Ball (someone will bring it in)
- Clear packing tape(Leg)
- PVC pipe (1 ½ inch size) (about 7 feet) (bone)
- 3 way 1 ½ inch pvc pipe connector
- Tiny fuzzy red and white POM POM balls (blood cells)
- Nuts & Bolts, along with washers and spring washers.
- Wood (2 of 3ft x 2in, 2ft x 2in, 3ft x 3ft plywood) (stand)
IV. Construction Plan:
- Cut pvc pipe into correct sizes
- Attach the pvc together with door hinges
- put the POM POMS in the bone to represent the red and white bloods cells
- Attach the surgical tubing to the “bones” with staples from staple gun
- Attach different bones to a frame that will hold it up

Relate To The Real World
Our leg was modeled after a group member’s and is therefore to scale. We engineered our leg to work like a real leg. We used opposing muscle groups like in real life and attached tendons to the bones and muscle. The muscle is made out of elastic material which can contract and expand exactly like real life. In addition, we placed red and white pom pom balls to represent red and white blood cells inside the PVC pipe.
- Refer to the slideshow
- Our model displays the functions of the muscular and skeletal systems.
- Muscular: Contraction and Relaxation of the main leg muscles
- Skeletal: Structure, Support, Blood Cell Protection
- We didn’t model all of the muscles in the leg. We only modeled the quad and the hamstring as well as the calf and Achilles tendon.
- We brainstormed ways to incorporate the muscular system and skeletal system into one model.
- We decided to model a leg.
- Next we considered the materials we would need to build our model (such as PVC pipe, elastic bands, and wood) and compiled a list.
- We acquired these materials.
- We started by putting together and painting the wooden frame.
- Once we finished the frame, we measured a group members leg and used those measurements to cut the PVC pipe to the desired length for the bones.
- A hinge was attached to the ¨bones¨ to connect them.
- After that we drilled holes in the PVC pipes to attach the tendons and muscles.
- We made the tendons out of string and tied them to the muscles (made out of elastic bands).
- We tied knots in the tendons and threaded them through the holes in the bone.
- We attached both ends of the muscles and tendons to the bone and created opposing pairs so the leg would function realistically.
- We attached the top of the leg to the frame.

- Presentation creation: E.C. Schneider, Ronan Shaffer, Bronte Hoefer, Yazeed Hamami
- Our group worked as a cohesive unit with deadly speed and precision. We are a killing machine, destined to take out all competition in order to achieve our goal BY ANY MEANS NECESSARY. Overall, our group worked well together. We all contributed our ideas and time to achieve a common goal, without too many disagreements. This helped our efficiency and timeline so we could meet the deadlines we were presented with.
