Answer 6

-blood
-lymph Hy

Question 7

Hyaline cartilage

Answer 7

-40% collagen ( mostly type II)

Question 8

3 major bone cell types

Answer 8

osteocytes
osteoblasts
osteoclasts

Question 9

contraction results from

Answer 9

sliding interaction of thick myosin filaments and thin actin filaments inside muscle cells

Question 10

skeletal muscle

Answer 10

-usually attached to bones by tendons
-motion, posture, heat production, protection

Question 11

epimysium

Answer 11

-external sheath of dense connective tissue
-septa extend inwards carrying larger nerves, blood vessels and lymphatics

Question 12

perimysium

Answer 12

-thin connective tissue which surrounds each fasicle (bundle of muscle fibres)
-fibres within a fasicle make up a functional unit and work together

Question 13

endomysium

Answer 13

-thin layer of reticular fibres and fibroblasts that surrounds the external lamina of individual muscle fibres

Question 14

cardiac muscle

Answer 14

-elongated, branched cells bound to each other by intercalated discs
-contraction is vigorous and rhythmic

Question 15

smooth muscle

Answer 15

• found in iris of the eye, walls of blood vessels, airways to lungs, stomach, intestines, gallbladder, urinary bladder and uterus

Question 16

neurons

Answer 16

respond to stimuli by altering the ionic gradient that exists across their plasma membrane

Answer 17

support

Question 18

role of oligodendrocyte in CNS and schwann cell in PNS

Answer 18

insulation, myelination

Question 19

role of microglia in CNS

Answer 19

immune surveillance and phagocytosis

Question 20

role of ependymal cell in CNS

Answer 20

creating CSF
