Anatomy & Physiology Cytoskeletal Elements

Cytoskeletal Elements

scaffolding of the cell

Microfilaments

allow for cell movement and plasma membrane stability

Microtubules

produce part of the spindle

Centrioles

formation of the spindle

Intermediate Filaments

resist mechanical pulling forces on cell

Inclusions

substances are found suspended in cytosol

WHAT IS THE FUNCTION OF THE CYTOSKELETAL ELEMENTS?

maintain cell shape

NAME ONE CYTOSKELETAL ELEMENT

microtubules

GIVE ONE OF THE FUNCTIONS OF THE MICROTUBULES

form mitotic spindles

WHAT IS THE FUNCTION OF MICROVILLI?

increase surface area for diffusion

WHAT ARE THE PROTEINS THAT FORM THE MICROTUBULES CALLED?

tubulins

NAME ONE OF THE TWO PROTEINS THAT MAY FORM MICROFILAMENTS

actin

NAME ONE OF THE TWO STRUCTURES THAT MAY BE FORMED FROM THE CYTOSKELETAL ELEMENTS

cilia

GIVE ONE OF THE FUNCTIONS OF THE MICROFILAMENTS

cell motility

GIVE ONE OF THE FUNCTIONS OF THE INTERMEDIATE FILAMENTS

tensile strength

THE CELL CYTOPLASM CONTAINS VARIOUS SUBSTANCES AND STRUCTURES THAT ARE NOT PART OF THE ACTIVE METABOLIC ACTIVITY OF THE CELL, SUCH AS STORED FOODS, PIGMENT GRANULES, CRYSTALS, WATER VACUOLES AND INGESTED FOREIGN MATERIALS, THEY ARE COLLECTIVELY CALLED ________________________
