Skeletal and Muscle Worksheet
What percent of the body is smooth muscle? Striated muscle?
5% to 10% is smooth or cardiac muscle. 40% is striated muscle.
Name 3 types of muscle proteins. What is the function of each?
*Stroma protein- skeleton, to hold the rest of the structures in place.
*Cellular proteins- Compromise about 1/5 of the muscle protein (enzymes).
*Contractile proteins- Are essential for contraction. They constitute 35% and 15% of the total muscle protein, respectively.
What is a myofibril?
An independent cylindrical element, A single muscle cells. Responsible for banding pattern.
Sketch a picture of a sarcomere. Label the I-band, the A-band, the Z-line and the H-zone.
On a separate piece of paper.
Name the two filaments that make up a sarcomere.
The thick filament- composed of myosin molecules
Also the thin filament- composed of actin, troponin, and tropomyosin.
Draw a sarcomere at rest, stretched out and contracted.
On a seperate piece of paper.
What is the sliding filament theory?
* The state of contraction
Muscle relaxation ensues upon the removal of what?
* Calcium ions

Basic Joint Anatomy Worksheet
Why is there little to no movement in a fibrous joint?
*Because it is hold tightly together by the fibrous tissue.
What is an example of a fibrous joint?
* The skull
Describe a cartilaginous joint and give an example.
* The cartilaginous joint hold united bones by the intervening fibrocartilage, and has very little movement. An example is the intervertebral discs on the vertebrae located on the spinal column.
What type of joint essentially allows free movement?
*Synovial Joints
What lubricates a joint cavity?
* Synovial fluid
For the following joint types please list the name of the joint type, the type of movement of the joint, the shape of the joint and an example.
Plane joint- Curved articular that permits gliding and slipping in a direction carpal bones.
Hinge joint- like an irregular cylinder that fits into concave groove elbow joints.
Condylar joint- Has two surfaces in each bone called condyles, similar to the hinge joint the knee joint is an example.
Ball and Socket joint- Spherical articulation which fits into a cup shaped cavity on the other bone can movement possible, shoulder joint.
Ellipsoidal joint- Wrist joint, oval that permits movement in variety directions.
Pivot joint- Has a bony peg that fits into concave notch which makes it rotate, the radius and ulna.
Saddle joint- Two western saddles movements occur in variety directions, joint at the base of the thumb.

Support the body, Protecting internal organs, Provide muscle attachment, and Blood cell production
How many bones are there in the human body?
About 206
What are the two divisions of the skeletal system? Name 5 specific bones in each division.
Axial Skeleton- skull, pelvis, ribs, coccyx, and sacrum
Appendicular skeleton- humerus, ulna , phalanges, patella, and tibia.
What bone makes up the upper arm?
* Humerus
What bone makes up the face?
* skull
Name two bones that protect vital internal organs.
* Ribs cage, and pelvis
What bone in the forearm is always on thumb side?
* Radius
What bone is movable for back muscles to attach to?
* Vertebral column
What bone is also known as the shin bone?
* Tibia
Sketch a human skeleton and label the following bones: skull, clavicle, sternum, humerus, radius, ulna, patella, femur, tibia, fibula, pelvis, vertebral column, scapula and rib cage.

Video Questions
1. Do you think that the symmetry test conducted on the baby was flawed? How? Describe how you would design an experiment that could fool the baby and skew the results.
Well in my opinion the experiment only supports their opinion but doesn’t really prove anything at all. I don’t think babies know the difference between ugly and beautiful unless it was something really horrible. They should have demonstrated other babies taking that same experiment. I think a baby stays penetrated on the picture that comes out first. Well I wouldn’t make experiments for any reason with babies.
2. What is missing from this video about beauty?
I notice that this video doesn’t describe the inside beauty. Other people have like the example of Bill Gates, he isn’t super fine but his brain took him further than any other beautiful person has gone through. Inner beauty is the most important subject because without inner beauty a person cannot reflect the value a person really has.
3. What are features that might break the “typical” beauty rules? How are these different from the “typical” beauty rules?
Well being asymmetrical breaks the supposable typical rules but yet there are beautiful people that are not
4. How does this video make you feel about beauty?
Well beauty can cause people to do many things as the video shows and that is really upsetting. It makes me feel that beauty is taken so far for some people leading them not be satisfied with themselves. Um and disgusted after seeing the surgery people had and the strength they had to do that.
5. What is it about the skin that makes it returning to its place? What property is this?
* Elastic properties make come back to its place.
6. What are the risks of cosmetic surgery? Would you ever do it? What would you be willing to risk for cosmetic surgery? How long will it last?
The risky part is being in coma for so long and something going wrong disaffirming a part of your body. On the other hand if I had the body that lady had I would take the risk because that was nasty. I thank god because there is nothing in me that I would want to change in particular. So no, I wouldn’t risk it only with all the exaggerating fat hanging and not having any other solution.
7. Someone in the video is quoted as saying “make-up can make anyone prettier.” Do you agree with this? Support your answer.
Well make up does help everyone but not everyone needs it. There are beautiful people who don’t need it but at a certain age it can help. Its like a painting, color gives it a brighter sight of it, but it’s not necessary. I just know that makes up does some miracles on some persons.
8. Do you think that there are cultural differences in how cosmetic surgery is viewed?
No surgery is just disgusting and nasty when it deals with blood. Um I don’t know but religious people are most likely to go against it. And in the other hand some may love the technology there is to help them, with the risk of something going wrong. Everyone has their own opinion regarding their self-esteem.
