Flashcards in Pathology of Sports Injuries Deck (23):
1

Define Trauma

Physical injury or wound that is produced by an external or internal force

2

Define Load

External force or forces acting on internal tissue

3

Define Stiffness

Ability of a tissue to resist a load

4

Define Stress

Internal resistance to an external load

5

Define Strain

Extent of deformation of tissue under loading

6

Define Elasticity

Property that allows a tissue to return to normal following deformation

7

Define Plastic

Deformation of tissues that exists ater the load is removed

8

Define Creep

Deformation of tissues that occurs with application of a constant load over time

9

Define Mechanical Failure

Excceeding the ability to withstand stress and strain causing tissue break down

10

Define Yeild Point

Elastic limit of tissue, point of no return

11

Define Compression

External loads applied toward one another

12

Define Tension

Force that pulls or stretches tissue

13

Define Shearing

Loads are applied to opposing surfaces forcing those surfaces to move in parallel directions relative to one another

14

Define Torsion

Twisting

15

Ability of Muscle Fibersq

Contract
Irritability
conductivity
elasticity

16

Types of muscle in the body

SMooth
cardiac
striated

17

Grade 1 Strain

Some muscle fibers have been stretched or actually torn
Tenderness.
Movement is painful but full range of motion is usually possible

18

Grade 2 Strain

Number of fibers have been torn
Depression or divot can be felt
Swelling discolorisation

19

Grade 3 Strain

Complete Rupture

20

Define Clonic Spasm

Involuntary muscle contraction characterized by alternating contraction and relaxation in rapid succession

21

Define Tonic Spasm

Characterized by constant contraction that lasts over a period of time

22

Define Tenosynovitis

Inflammation of a tendon and its synovial sheath

23

Define Myositis Ossificans

Calcum deposits that result from repeated trauma
