4 October 2006 Cytoskeleton Microtubules Actin filaments (microfilaments) Intermediate filaments Microtubules Hollow Consists of individual “bricks” called tubulin molecules which are protein molecules—they come in pairs called “Tubulin dimer”=alpha tubulin and beta tubulin 13 rows of tubulin dimmers proteins attach called microtubule-associated proteins (MAPs) MAPs give microtubules their function “motor” proteins: Kinesin Dynein Form in Microtubule Organizing Centers (MOCs) Centrioles Manufacture microtubules Cilia/cilium Covered by plasma membrane Contains microtubules 9-2 organization for movement: microtubules, dynein molecules, and ATP Kartagener’s Syndrome-Immotile cilia syndrome Chrome bronchitis, partial hearing loss, sterility, reversed organs It’s hereditary like ‘other’ disease Microfilaments

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
