3
|
A hollow rod composed of tubulin proteins that makes up part of the cytoskeleton in all eukaryotic cells and is found in cilia and flagella.
|
5
|
A circular flow of cytoplasm, involving interactions of myosin and actin filaments, that speeds the distribution of materials within cells.
|
6
|
A cable composed of actin proteins in the cytoplasm of almost every eukaryotic cell, making up part of the cytoskeleton and acting alone or with myosin to cause cell contraction.
|
7
|
A structure present in the cytoplasm of animal cells that functions as a microtubule-organizing center and is important during cell division; has two centrioles.
|
8
|
In cilia and flagella, a large motor protein extending from one microtubule doublet to the adjacent doublet; ATP hydrolysis lead to bending of cilia and flagella.
|
9
|
A network of microtubules, microfilaments, and intermediate filaments that extend throughout the cytoplasm and serve a variety of mechanical, transport, and signaling functions.
|
11
|
A eukaryotic cell structure consisting of a “9 + 0” arrangement of microtubule triplets; may organize the microtubule assembly of a cilium or flagellum and is structurally very similar to a centriole.
|
12
|
A protein that interacts with cytoskeletal elements and other cell components, producing movements of the whole cell or parts of the cell.
|
13
|
A structure in the centrosome of an animal cell composed of a cylinder of microtubule triplets arranged in a “9 + 0” pattern.
|
14
|
A cellular extension of amoeboid cells used in moving and feeding.

|
|
1
|
The outer region of cytoplasm in a eukaryotic cell, lying just under the plasma membrane, that has a more gel-like consistency than the inner regions due to the presence of multiple microfilaments; in plants, ground tissue that is between the vascula
|
2
|
A type of motor protein that associates into filaments that interact with actin filaments to cause cell contraction.
|
4
|
A component of the cytoskeleton that includes filaments intermediate in size between microtubules and microfilaments.
|
10
|
A globular protein that links into chains, two of which twist helically about each other, forming microfilaments in muscle and other kinds of cells.
