Answer 7

gila

Question 8

– nerve cell; conducts action potentials; parts:

Answer 8

neuron

Question 9

– contains nucleus, site of general functions

Answer 9

cell body

Question 10

receive stimuli leading to electrical charges that either increase of
decrease action potentials in the neuron’s axon

Answer 10

dendrites

Question 11

Thin sheet or layer of tissue that covers a
structure or lines a cavity.

Answer 11

tissue membrane

Question 12

Line cavities that open to the outside of the body (such as digestive, respiratory, and
reproductive tracts).

Answer 12

mucous membrane

Question 13

Line cavities that do not open to the exterior of the body such as pericardial, pleural, and
peritoneal cavities.

Answer 13

serous membrane

Question 14

Line the cavities of freely movable joints.

Answer 14

synovial membrane

Question 15

makes joint very slippery, reduces friction, allows smooth movement
within the joint.

Answer 15

synovial fluid

Question 16

Occurs when tissues are damaged; can also result from the immediate and painful events that
follow trauma.
● Mobilizes the body’s defenses and isolates and destroys microorganisms, foreign materials,
and damaged cells to that tissue repair can proceed.

Answer 16

inflammation

Question 17

– swelling; results when water, proteins, and other substances from the blood move
into the tissues

Answer 17

edema

Question 18

protein, forms a fibrous network that walls off the site of injury from the rest of
the body.

Answer 18

fibrin

Question 19

phagocytic white blood cell that fights infections by ingesting bacteria; die
after ingesting a small number of bacteria

Answer 19

neutrophil

Question 20

mixture of dead neutrophils, other cells, and fluid that can accumulate.

Answer 20

pus

Question 21

– prolonged inflammation; results when the agent responsible for an
injury is not removed or something else interferes with the healing process.

Answer 21

chronic inflammation

Question 22

Substitution of viable cells for dead cells.; can occur by regeneration or by fibrosis.

Answer 22

tissue repair

Question 23

new cells are the same type as those that were destroyed, normal function is
usually restored.

Answer 23

regeneration

Question 24

replacement; new type of tissue develops, eventually causes scar production and
the loss of some tissue function.

Answer 24

fibrosis

Question 25

contains thread-like protein fibrin which binds the edges of the wound together and stops the bleeding.

Answer 25

clot
