Answer 7

help clot blood

Question 8

plasma

Answer 8

Liquid ground substance is called

Question 9

Muscle tissue

Answer 9

Cells contract (shorten) when stimulated
Contraction causes movement
Voluntary and involuntary movement of skeleton
Involuntary contraction of heart
Propulsion of material through digestive and urinary tracts

Question 10

3 types of muscle tissue

Answer 10

Skeletal
Cardiac
Smooth

Question 11

Answer 11

Moves skeleton
Does not contract unless stimulated by somatic nervous system
Voluntary (with some involuntary reflexes)

Question 12

Answer 12

Long cylindrical cells Arranged in parallel bundles that run length of entire muscle
Multinucleated

Question 13

Striations

Answer 13

Alternating light and dark bands

Question 14

Cardiac muscle tissue

Answer 14

In heart. Contraction pumps blood

Question 15

Involuntary

Answer 15

Pacemaker cells initiate contraction
Visible striations
Cells short and often branched
One or two nuclei

Question 16

intercalated discs

Answer 16

Cells connected
Strengthen connection between cells
Promote rapid conduction of electrical activity

Question 17

Smooth muscle tissue

Answer 17

Involuntary muscle tissue
Found in walls of intestines, stomach, airways, bladder, uterus, blood vessels Helps propel movement through these organs
Appearance
Lacks striations; appears smooth
Cells are spindle-shaped
Cells short with one central oval nucleus

Question 18

Nervous tissue

Answer 18

Located in the brain, spinal cord, and nerves cells called neurons

Question 19

glial cells

Answer 19

Do not transmit nerve impulses
Instead, protect, nourish, and support neurons

Question 20

Cell body

Answer 20

Contains nucleus and other organelles

Question 21

Nerve cell processes

Answer 21

extend from cell body
Shorter and more numerous processes are called dendrites
Receive incoming signals

Question 22

Axon

Answer 22

single long process extending from the cell body
Send signals to other cells
