The Basics & Connective Tissue Flashcards
static vs dynamic
static= non moving systems, not passives just still. active stability
dynamic=moving systems
kinetics vs kinematics
kinetics=FORCES. act on body to generate or alter movement
kinematics=analysis of movement in terms of mechanical elements (time / space)
example of kinetics vs kinematics
yoshi slips on banana peel.
kinetics= gravity, friction between floor and banan
kinematics=center of gravity, how fast you walked
4 parts of human movement
1 mobility 2 stability (supported) 3 balance (disbrtn of wght) 4 coordination (organization of diff elements)
kinetic chains
series of joints linked by arrangement of muscles and bones along pathway of movement
4 structures essential for movement
- CT formation
- joints
- muscles
- nerves
examples of static and dynamic movement:
static: sitting in meditation pose, mountain pose yoga
dynamic: jumping, standing on one foot
examples of coordination and movement:
coordination: squatting with weight, throwing ball
movement (kinetic chain): vacuuming, carrying backpack, eating)
ECM
-made of protein fibers
-determines structure and functional properties
-made of collagen, elastin, reticular.
(collagen=most abundant protein. elastic=thinner than collagen. flexible. reticular=meshwork)
soft tissue properties (8)
- stretch -lengthen w/o damage
- plasticity- capacity to be altered and retain to config.
- elasticity- capacity to recoil
- thixotrohpy- responds to change in temp. (fingers in cold temp)
- tensile strength- ability to be pulled in 2 directions
- creep- gradual change in shape (desk job=neck change)
- piezoelectric effet-CT is put under mechanical stress. ex=electrical stim
- collodial- composed of sloid particles in fluid . increased forced = increased opposition. ex: jumping from tall building to water = most likely to break leg trying to oppose stronger force.
2 ways to categorize CT
structure and function
Types of CT structure (5)
1 liquid-blood, mucus
2 loose-small # fibers in large ground tissue
3 dense-ex tendons, 4 ligaments, joint capsules
4 cartilaginous: hyaline, fibrocartilage, elastic cartilage
5 osseous- bones
Types of CT functions (3)
- compressive (ex. bones & cartilage to bear weight)
- tensile (ex. fasciae, tendons, ligaments)
- impacted by force
types of bone (5)
- long- support weight of body
- short- provide stability
- seasmoid-bone in tendon
- irregular- protect tendons from stress and wear
- flat- provide protection like a shield
main function of bone
- maintain body shape
- allow weight bearing
- support of tissues
- provide framework and spacing
- levers for movement
