Tendons Flashcards
Block 1 (16 cards)
what do tendons do
attach muscle to dones
Muscle attachments
vary in shape and how they attach to bone or cartilage
range of muscle attachments
aponeurosis (flatten sheet) to tendon (fibrous cord like)
what is a tendon
a dense, connective tissue structure
tendons have what tpe of resistane
great to mechanical loads
do tendons have metabolic needs
no, have low metabolic needs and are poorly vascularized
Aponeurosis (es)
type of tendon that is arranged as a thing sheet, serves as a wide attachment
Raphe
a seam, line of union between halves of symmetrical parts
tendon origin vs insertion
origin - the fixed point (proximal attachment)
Insertion - the point moved by muscle contration (distal attachment)
protective structures of tendons
synovial bursa and tendon sheath
how can tendons be damaged
excessive press or friction, particulary when changing direction over bone prominences
Tendon sheath
wraps arounf the greater circumference around the tendon
Synovial bursa
present only on one side of the tendons
Intrinsic factors of tendon injuries
age, BW, nurtition
Extrinsic factors of tendon injuries
sport related, excessive forces or loading, poor training techniques, environmental conditions
Avulsion
detached bone fragment from excessive tension
