Anatomy & Physiology: The Unity Of Form & Function, 8th Edition (Ch. 3:
Cellular Form and Function) Questions & Answers 2023/2024
cytology - ANSWER-scientific study of cells
cell theory - ANSWER-the theory that cells form the fundamental structural and functional units of all
living organisms
cells - ANSWER--functions: fight disease, store nutrients, connect things, line things, gather information
and control body functions, involved in reproduction
-structure:
*nuclear envelope -> nucleus -> nucleolus
*plasma membrane
*cytoplasm -> cytoskeleton, organelles, inclusions, cytosol
intracellular fluid - ANSWER-fluid within cells; cytosol
extracellular fluid - ANSWER-fluid outside the cell; tissue fluid (ex. blood plasma, lymph, and
cerebrospinal fluid
cytoplasm - ANSWER-fluid between the nucleus and surface membrane; contains the cytoskeleton,
organelles, and inclusions
plasma (cell) membrane - ANSWER--stick cells together to form tissues; regulates exchange of materials
that go in and out of a cell; involved in intracellular communication; gives cell its shape
-made of proteins, lipids, & carbohydrates; phospholipids are major components; semi-permeable
membrane
cytoskeleton - ANSWER--supportive framework of protein filaments and tubules
-network of protein filaments and cylinders that structurally support a cell, determine its shape,
organize its contents, direct the movement of materials within the cell, and contribute to movements of
the cell as a whole
-composed of microfilaments, intermediate filaments, and microtubules
organelles - ANSWER-diverse structures that perform various metabolic tasks for the cell
inclusions - ANSWER--highly variable - fat droplets, glycogen granules, protein crystals, dust, bacteria,
viruses; never enclosed in membranes
-foreign matter retained in cytoplasm
-(function) storage products or other products of cellular metabolism
phospholipids - ANSWER-75% of membrane molecules of the plasma membrane; drift laterally from
place to place, spin on their axes, and flex their tails
glycolipids - ANSWER-5% of membrane lipids molecules of the plasma membrane; phospholipids with
short carbohydrate chains on the extracellular face of the membrane; help form the glycocalyx
