connective tissues Flashcards
EPItenon
SURROUNDS tendon fascicle
ENDOtenon
SEPARATES tendon fascicles
predominant collagen type in tendon?
type I (85% dry weight)
4 transitional tissues at muscle-tendon attachment?
tendon
fibrocartilage
mineralized fibrocartilage
bone
collagen type in tendon EARLY healing?
type III (converted to type I)
tendon repair process post-surgery
weakest 7-10days
max strength 6mos
predominant ligament collagen type?
type I (90% dry weight)
higher ELASTIN content
LIGAMENT > tendon
2 types of ligament insertion?
INDIRECT (acute angle)
DIRECT (right angle)

ligament
fibrocartilage
mineralized fibrocartilage
bone
ligaments plastically deform?
NO. “break not bend”
collagen type in ligament EARLY healing?
type III (converted to type I)
nucleus pulposus content
high GAG, low collagen (opposite for annulus fibrosis)
4 phases of soft tissue healing
hemostasis
inflammation
organogenesis
remodeling
