Inflammation of muscle
strainmyositis TERM 2
inflammation of joint capsule
DEFINITION 2 capsulitis TERM 3
inflammation of ligament
DEFINITION 3 sprain TERM 4
CT proper DENSE
DEFINITION 4 DENSE Tendons -- parallel arrangement of fibers Ligaments -- varied arrangement of fibers joint capsules aponeuroses fascia -- continous with itself throughout the body and lacks obvious organization of fibers TERM 5
CT proper LOOSE
DEFINITION 5 beneath skin like packing material between muscles enveloping them and continous with periosteum of bone between organs as endothoracic and endoabdominal paratendon in the synovial layer
Specialized CT
CARTILAGE
Hyaline -- Between articulating bones Fibrocartilage -- IV discs, Menisci, TMJ disc, Adipose tissue Bone Muscle TERM 7
Elastin
DEFINITION 7 Allow tissues to deform and return to preexisting state Lungs Blood vessels Ligaments with large proportion of elastin have more flexibility than tensile strength Ligamentum flavum TERM 8
Beighton score
DEFINITION 8 developed for children to ID soft tissue diseasesHypermobility describes joints that stretch further than normal. For example, some hypermobile people can bend their thumbs backwards to their wrists, bend their knee joints backwards, put their leg behind the head or perform other contortionist "tricks". TERM 9
CT diseases
DEFINITION 9 genetic defects of collagen synthesis -- too much elastin genetic predisposition autoimmune disorders unknown autoimmune types unknown hormonal unknown TERM 10
genetic defects of collagen synthesis
DEFINITION 10 ehlers danlos -- affects joints marfan syndrome -- affects all tissues (heart and heart valves particularly) Hypermobility syndrome (HMS)
The effect of end-range loading
When spine is loaded at end-range, creep occurs Squeezes fluid out of the compressed IV disks, the cartilage of the facet joints, and the stretched spinal ligaments Deprives the soft tissues of part of their nutrition Straightens the natural collagen crimp where Fibrils elongate under sustained load Recovery takes considerable time TERM 17
Types of injury that can occur to
muscle
DEFINITION 17 strain contusion laceration compartment syndrome TERM 18
Contusion
DEFINITION 18 blunt force trauma TERM 19
S+S of muscle strain
DEFINITION 19 History of acute onset by Overstretch or Excessive loading Pain localized in area of injury at the Musculotendinous junction Pain with contraction (force on msktendinous jxn) Pain with stretch 1 and 2 Pain with palpation of muscle belly depends on severity May be discolored if severe as Blood pools distal to injury Weakness present in 2 and 3 TERM 20
S+S muscle contusion
DEFINITION 20 Result of a direct blowDifferent hx than muscle strainCharacterized by edema and discolorationPain local to the area of injury palpation of injured area muscle contraction stretch of muscle belly
Muscle healing
proceeds like other tissues
