By Armando Hasudungan

Important : For now, think of an action potential as a small electrical impulse
Before you watch the video define the following in a way that you understand it.
1. Skeletal muscle
2. Epimysium
3. Muscle Fascicle
4. Muscle Fiber
5. Sarcolema
6. Sacoplasmic Reticulum
7. Transverse Tubules (T Tubules)
8. Cisternae
9. Actin

1. From the video create a written step-by-step explanation of muscle contraction.
2. From the video create 5 questions that can be used on a quiz.
3. Recreate a drawing of the muscle with fascicles, fibers and myofibrils as shown in the video.
4. Recreate a drawing of the sarcomere as shown on the video.
5. Create an ongoing list of terms and their definition.

We will next explore Cross Bridging (When actin and myocin interact with each other to move (contract). Please enjoy the following video. It offers a wonderful visual.

Perry Program for Females Interested in Science.

Hi Richard,

We’re very excited to announce an upcoming Perry Outreach Program on Saturday, January 23 at Kaiser Permanente Hospital in San Jose, CA. The Perry Outreach Program is a free, one-day, hands-on experience for high school and college-aged women who are interested in pursuing careers in medicine and engineering. Students will hear from women leaders in these fields and try it for themselves by performing mock orthopaedic surgeries and biomechanics experiments.

We are now seeking applicants for our San Jose program. Participants should be women in grades 10 and up with an expressed interest in science, medicine and/or engineering. We would very much appreciate if you could pass this information along to any high school principals, high school science teachers or high school students you may know. Applicants should be directed to fill out our online application in advance of the Dec 22 application deadline.

Additional information can be found on our website: www.perryinitiative.org

The application may be accessed directly using the following link: http://perryinitiative.org/programs/student-online-application/

More information and a printable flyer for this event can be found here. Please feel free to contact me directly with any questions you may have. Again, we sincerely appreciate your help in identifying qualified applicants for our program.

All the best,

Manuela Restrepo, Program Coordinator

GHA Seniors IMPORTANT!!!

Hello Galileo Health Academy Seniors!

I hope your semester is going well!!! I received a message from some of you that you were concerned about your CCSF grades being entered to your high school transcript; however, I didn’t receive any emails. Just a reminder, because of my work, it is best to reach me by email which you should all have. If not, please save it now. From email, I will respond as quickly as possible. Unfortunately, I did not get the transcripts in my hand until a little bit later than when you submitted them and it is a time consuming process; however, I will have them all entered by Monday, October 26th.

I don’t think I received everyone’s CCSF transcript, but I will give a list of the ones I entered to Mr. McDowell next week, so he can review with you. Then you can let me know if you weren’t on the list by EMAIL (chavezm1@sfusd.edu).

Also, and VERY important, I can put your CCSF courses on your high school transcript; however, that is not enough for college admissions. You must also do the following on your own, but you can contact me if you need any help. Please review:

1. You should add the course(s) you took at CCSF to your college applications. Please visit your counselors for assistance.

2. Send your OFFICIAL CCSF transcript to the university you are interested or planning to attend. You can wait until you have been conditionally accepted, but if anyone is doing early decision, you should send sooner. Having the grades on your high school transcript, is NOT enough. Please review the handout attached to explain everything you should know about CCSF transcripts. The second handout is the one I shared before to help you log into WEB4 to access and send your official transcripts.

I hope this information helps. Please let me know if you have questions! Thank you!! : )
