funal bioe

Question 1

bone phases

Answer 1

cortical and trabecular

Question 2

corticular

Answer 2

is the dense outer shell, responsible for carrying the majority of
the mechanical load

Question 3

trabecular

Answer 3

(or cancellous) is a much more porous mesh within the bone

Question 4

tendons

Answer 4

connect muscle to bone
less elastin
viscoelastic
higher loading than ligamnets

Question 5

ligaments

Answer 5

connect bone to bone
more elastic with more elastin

Question 6

what type of material are ligaments and tendons

Answer 6

they are passive, cannont actively generate tension or force

Question 7

ligaments and tendons composition

Answer 7

collagen and elastin

Question 8

type of behavior for ligaements and tendons

Answer 8

non-linear

Question 9

stress-strain of ligaments and tendons

Answer 9

elastin on first curve then collagen at the end (stiffness is high

Question 10

difference b/w ligaments and tendons

Answer 10

tendons: need stiffness to tensmit muscle force
ligaments: stabilize joints

Question 11

why non linear for tendons and ligaments

Answer 11

crimpled nature of the collagen fibrils,
transition from crimped to tensed casues a change in linearity

Question 12

three regions of tendon

Answer 12

1.nonlinear toe
2. quasi linear region
3. failure region

Question 13

viscoelasticity

Answer 13

measure of resistance to flow

Question 14

dashpot

Answer 14

energy dissipated

Question 15

sprng

Answer 15

energy recovered

Question 16

creep

Answer 16

constant stress; gradually elongates

Question 17

stress relaxation

Answer 17

constant strain; gradually recovers
