GUARANTEED TO PASS
◉ Mediastinum. Answer: contains pericardial cavity which encloses
heart
◉ Abdominopelvic cavity. Answer: inferior to diaphragm; 2 parts not
separated by muscle or membrane; abdominal cavity and pelvic
cavity
◉ Abdominal cavity (superior portion). Answer: houses stomach,
intestine, spleen, liver, other organs
◉ Pelvic cavity (inferior portion). Answer: lies on pelvis- houses
urinary bladder, some reproductive organs, rectum
◉ Abdominopelvic Quadrants. Answer: Right Upper Quadrant, Left
Upper Quadrant, Right Lower Quadrant, Left Lower Quadrant
◉ Abdominopelvic Regions. Answer:
,◉ Serosa (serous membrane). Answer: thin, double-layered
membrane, lines walls of ventral body cavity and outer surfaces of
organs
◉ Visceral serosa. Answer: covers organs, visceral pleura, visceral
pericardium, visceral peritoneum
◉ Parietal serosa. Answer: lines cavity walls, parietal pleura, parietal
pericardium, parietal peritoneum
◉ Pleurisy/peritonitis. Answer: causes roughening of pleurae or
peritoneum causes organs to stick together and drag across one
another-very painful
◉ Pleurisy. Answer: inflammation of pleura(e)
◉ Peritonitis. Answer: inflammation of peritoneum
◉ Cell. Answer: cell theory: basic structural and functional unit of
the body
◉ Cell structure and function are _____. Answer: complementary
,◉ Continuity of life has cellular basis. Answer: cells can arise only
from other preexisting cells
◉ Cell diversity. Answer: over 200 different types of human cells
types differ in size, shape, and sub cellular components; these
differences lead to ***differences in function***
◉ Generalized cell. Answer: all cells have some common structures
and functions
◉ 3 basic parts of human cells. Answer: plasma membrane,
cytoplasm, nucleus
◉ Plasma Membrane. Answer: flexible outer boundary
◉ Cytoplasm. Answer: intracellular fluid containing organelles
◉ Nucleus. Answer: DNA containing control center
◉ Specialized Cells. Answer: red blood cells, skeletal muscle cell,
neuron, sperm cell
◉ Red Blood Cell. Answer: small, no nucleus
, ◉ Skeletal muscle cell. Answer: cylindrical, multi-nucleated, long
◉ Neuron. Answer: cell body with axon and dendrites, may not be
detectable to human eye but can have an axonal process 1 meter
long
◉ Sperm cell. Answer: flagellated
◉ There are specialized cells for certain functions that have ____.
Answer: characteristic structural modifications
◉ All cells have to ____ so all cells have basic ____. Answer: metabolize
to stay alive.... structural similarities
◉ Plasma/Cell Membrane. Answer: outer boundary of the cell,
separates inside of cell (intracellular) from outside of cell
(extracellular), control what enters/exits cell, very thin (5 to 10
nanometers), need electron microscope to see, acts as an active
barrier separating intracellular fluid (ICF) from extracellular fluid
(ECF), plays dynamic role in cellular activity by controlling what
enters and what leaves cell
◉ Structure of plasma membrane. Answer: consists of membrane
lipids that form a flexible lipid bilayer
