Skeleton Quiz

I took the Skeleton Quiz and got a 94%!!

Fractured Growth Plate

     My 8th grade year I was playing in a Basketball Traveling Team League. I was at practice with my team and I was running down to corner of the court when one of the posts threw a pass to tall for my 4'10 body. So I jumped to get the ball back into play and when I came down from my jump I landed with the bone of my ankle touching the floor. I remember when I landed it made a really odd sound it was like a crack and squish at the same time. Every time I remember that day it gives me the chills. About 10 seconds later I was staring to feel the pain of my ankle so I fell over and started to cry.... ALOT. My coach didn't know how severe my injury actually so was I was instructed not to take off my shoe so the swelling would be compressed. Then I went to the Hospital in La Junta they took x-rays and said I just rolled it but would send it to the Orthopedic Surgeon and he could look at them. Turn out La Junta emergency isn't that great at looking at x-rays and I had a fractured growth plate. 

     

     Long bones of the body don't grow from the center outward. So the growth will occur at each end of the bone and around the growth plate. When an adolescent becomes full-grown, the growth plates will harden into solid bone. Adults will not have a growth plate. Growth plates will only occur in children ages 10 to 15 years old. Since the growth plates are the last portion of bones to harden, they are most likely to fracture because the ligaments that attach to the tibia and fibula and to the talus bone are generally stronger than the growth plates. In some cases if not treated correctly the bone can actually grow in shorter or crooked. Most physicians will put the ankle in a cast so the bone can heal on its own.

  This is just a fun fact but most growth plate fractures occur twice as often in boys than girls and by age 12 most plates are closed. (mayo clinic).

Integumentary System- Keratosis Pilaris

This is a powerpoint about the Integumentary System and Keratosis Pilaris.

Standard 6 1st Quarter

So far in Anatomy and Physiology we have had 7 blog posts. 2 of them are quizzes. This first quarter I thought that I did really well. My posts were really thorough and explain the topic well. The best posts i would say I have is the Organization of the body, the Homeostasis post, and Models of Epithelia. I did these by my self and put a lot of effort into them. My worst post is the Histology lab only because I don't think it looks good and is very vague. I did that post with a partner and rushed it. Some detail I could work on is bringing in outside media sources like more pictures or youtube videos. I would say that my work is "4" material. I do put a lot of effort and time for each post. I want to keep the standard of my work high so I don't slack off, procrastinate, or turn in not quality work. That would be my goal for next quarter.

Histology quiz!

I got a 68 on my quiz. Not my best one, but histology is hard.

Histology Lab

Recently in Anatomy we did a lab about Histology. Histology is the the study of the microscopic structure of tissues. In my post before I talked about epithelia (cubiodal, columnar etc.) If you would like to know more go to my epithelial blog post!

Models of Epithelia

This “lab” was actually really fun. After physically becoming epithelia and reviewing the notes and creating this slide show of notes, I can saw that I know more about Epithelia. I am going to have to take advantage of the practice quiz and study A LOT!! Also I feel like I know more about my body. I am proud to say I have further knowledge of Epithelia and I am looking forward to learning more standards in Anatomy.

Orientation To The Body EXAM

I got an 88% on my exam of the body. YAY!

Organization of the Body: Learning Anatomical Terms

This is power point of the anatomical terms of the body, the planes, cavities, membranes, and the abdominopelvic region with and with out organs. Anatomy has a lot of terminology but is really necessary when you start getting into all the good stuff.

Homeostasis Lab aka Forced Hypothermia

Recently my lab group and I have created a forced hypothermia lab over a 10 minute period. We checked the 4 test people's vials (blood pressure, heart rate, and body temperature). With our findings we noticed that the body temperature would rise then regulate to the normal body temperature. The initial temperatures ranged from 97 to 99 then once our 4 test people entered the water they would drop about 2 to 3 degrees. This is because the body is in shock and is cold! Our heart rate would start high because they were nervous and then by the end it would go to normal rate but in-between the start and end the heart rate would drop which is because the heart's blood vessels will shrink because less blood is delivered to the heart.  The blood pressure was aortic because the body was in shock because of the cold. After this lab I learned that I am very glad I didn't go in the ice bath because not only were you cold people got grumpy! But in all seriousness homeostasis does really work and to see it in action was really amazing. I am glad we did this lab because I had the chance to visualize and learned more about homeostasis and how it works with the body.

Homeostasis

What is Homeostasis you might ask well in general terms it is "the ability to maintain a relatively stable internal environment in an ever-changing outside world"(Mr. Ludwig's notes). In my terms Hemostasis is the body adapting to a certain environment.

 With Homeostasis the internal environment of the body has a very delicate state of equilibrium. Equilibrium is a state of balance. As an example of this balance regulation of blood sugar or even hypothermia. The body has to regulate its self to keep it in balance. To keep this balance the body uses the negative feedback system if you have low blood sugar or a low glucose level the pancreas will release glucagon into the blood strew where the liver breaks down the glycogen stores and releases glucose into the blood where then your blood sugar or glucose level will rise to a normal state. The negative feed back system isn't just for bad situation like the one stated above it can also work in reverse. If a person has a high amount of blood sugar or high glucose level the pancreas stimulates insulin to bring it down which travels to the liver to be distributed into the blood and then the sugars will lower to a normal level.

Another "feedback" is Positive feedback. Positive feed back is the output enhances or exaggerates the original stimulus. That definition is hard to understand an easy way to think about this system is that if you have a cut your body clots it. This is  because the first set of  "clots" will arrive at the scene of the cut and send a chemical stating that it will need reinforcements so more clots will come and this process will happen until the cut is clotted and scabbed. That is an easier "feedback" than negative.

Some Key terms and pints to remember:
 Receptor-Monitors the environments and responds to changes (stimuli)
Control Center-Determines the set point at which the variable is maintained
Effector-Provides the means to respond to the stimulus.
Chemical, thermal, and neural factors interact to maintain homeostasis
