Question 2

what are the 4 types of tissue?

Answer 2

1. Epithelial 2. connective 3. muscular 4.Nervous

Question 3

epithelial tissue

Answer 3

-skin layers
-linings of cavities
-may secrete epithelium
-may be ciliated

Question 4

connective tissue

Answer 4

-adipose (fat)
-dense fibrous : tendon, aponeurosis, ligament ,fascia
-cartilage
-bone

Question 5

muscular tissue

Answer 5

-striated (voluntary, somatic)
-smooth (involuntary,autonomic)
-cardiac

Question 6

visceral muscle

Answer 6

smooth muscle
-associated with involuntary functions
-glands, digestion organs

Question 7

muscles

Answer 7

-made up of fibres
-fast twitch
-slow twitch

Question 8

fast twitch fibers

Answer 8

-contract quickly
- fine movement
-fatigue easily

Question 9

slow twitch fibres

Answer 9

• larger movements
  -exert greater force
• move slowly
• greater endurance
  -antigravity muscles of trunk

Question 10

Muscle function

Answer 10

-Only contract
-contractions brings two muscles together
-muscles w more fibre exert more force of contraction

Question 12

origin

Answer 12

point of attachment in muscle during contraction (immobile)

Question 13

insertion

Answer 13

point of attachment of muscle during contraction mobile

Question 14

agonist

Answer 14

(prime mover)
