structure and function of centrosomes {Ans: -located near nucleus -2 parts: pair of centrioles and pericentriolar matrix -centrioles = cylindrical structures each composed of 9 clusters of 3 microtubules in a circular pattern -pericentriolar matrix = contains hundreds of ring-shaped complexes composed of tubulin -tubulins build microtubules in non dividing cells; forms mitotic spindle during cell division}medial/lateral {Ans: medial: nearer to the midline lateral: farther from the midline}structure and function of desmosomes {Ans: -contain plaque that attaches to intermediate filaments and have transmembrane glycoproteins that extend into the intercellular space between adjacent cell membranes and attach cells to one another -contributes to stability of cells and tissue; prevent epidermal cells from separating under tension and cardiac cells from pulling apart during contraction}endocytosis {Ans: materials move into a cell in a vesicle formed from the plasma membrane}transverse plane {Ans: divides the body or organ into superior and inferior portions}proximal/distal {Ans: proximal: nearer to the attachment of a limb to the trunk distal: farther from the attachment of a limb to the trunk}identify the organ systems of the human body {Ans: integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, digestive, respiratory, urinal, male/female reproductive}nonciliated pseudostratified columnar
