Exam 2 Chapter5 Flashcards
Connective tissue
Ligaments and joint capsules while possessing some elastic properties
Flexibility
Ability to allow neuromuscular system to allow for efficient movement of a joint or series of joint through full non restricted pain free range of motion.
Adipose
Can act as a wedge between lever arms
Ballistic
Bouncing movement in which repetitive contractions of agonist work
Static stretching
Stretch to point of discomfort and holding at that point for period of time
15-30 seconds 3 to 4 times
PNF
Proprioception Neuromuscular Facilitation
Alternating contractions
Irritability
Motor unit that determines the amount of stimulation required to initiate the response of muscular fiber
Viscosity
Resistance that limits muscle contraction
Stiffness
Resistance of tissue or a structure to deformation or change in shape or length
Contracture
Failure of relaxation of a muscle
Isotonic
Change my n muscle length
Isokinetic activity
Activity that involves motion
PROM
Requires no active work towards part of the muscle.
AAROM
Move with assistance
AROM
Can produce full range of motion
Autogrnic inhibition
Relaxation of antagonist during contraction
Reciprocal inhibition
Contraction elicits additional relation of antagonist
Collagen
Provides tissue with strength and stiffness
Elastin
Fibers provide a structure with extensibility
Reticulum
Fibers are essentially type III collagen fibers
Ground substances
Is a structureless organic gel that serves to reduce friction between the collagen and elastin fibers
Regular connective tissues
To resist high tensile loads and still provide flexibility
Dense irregular connective tissue
Similar to regular connective tissue but is arrangement is not parallel
Areole
Is irregular and loose with relatively long distance between the cross links
Elasticity
Is the ability to return to normal length after an elongation force or load has been applied
Viscosity
Is the resistance to an outside force that causes a fluid like permanent deformation
Plasticity
Is the ability of a substance to undergo a permanent change in size or shape after deforming force applied
Creep
Elongation of tissue when a load usually of low level is applied over an extended time to cause plastic deformation.
Strain
Is the amount of deformation that occurs when a stress is applied
Ultimate strength
Greatest load of tissue
Hysteresis
When stress is released
Strength
Is the maximum force that a muscle can exert
Concentric
Muscle shortens
Eccentric
Muscle lightens
Cross training
When a muscle is not able to actively exercise or the patient is restricted from moving
Functional exercise
Activities are exercises that precede activity specific activities in a rehabilitation program
Activity specific exercise
Exercise that includes drills for specific sport
