Question 1

Muscle Tissue structure, function

Answer 1

structure: has ability to contract and relax

function:
- help control movement of oxygen, blood and nutrients, calcium and remove wastes
-control body movements internally as well as everyday physical activity.

Question 2

types of muscle tissue

Answer 2

skeletal, cardiac and smooth

Question 3

skeletal muscle structure, function

Answer 3

structure: voluntary, striated
function:
-to pull on bones to produce movement
-to provide stability and posture

Question 4

cardiac muscle structure, function

Answer 4

structure: involuntary, striated
function:
-to contract and relax to pump blood around the body

Question 5

smooth muscle structure, function

Answer 5

structure: involuntary, non-striated
function:
- to contract and relax to push fluids/food through the body

Question 6

epithelial tissue structure, function

Answer 6

structure: large sheets of continuous cells
function:
-protection - lines internal organs and external surfaces
-secretion of substances (e.g. gastric juices)
-absorption (e.g. nutrients)

Question 7

nervous tissue structure, function

Answer 7

structure: dendrites, cell body and axon
function:
-communication: detects stimuli, integrates information, transmits signals
- provide sensory information from body to brain
- sends motor signals from brain to body

Question 8

connective tissue structure, function

Answer 8

structure: most contain fibrous strands/ contain fluid component - ground substance
function:
1) support and structure of internal organs - help hold organs in place
2) transport of substances (blood and lymphatic vessels)
3) protective role
4) insulation
5) provides stability of movement
