Document Summary
Provide and maintain form in the body and give support to body. 3 kinds of connective tissue: syportive (bone cartilage, connective tissue proper. Dense- skin, ligaments, tendons loose- not resistant to stress or train: specialized connective tissues (adipose and hematopoietic tissue) Note: shear force- two fibers/structures sliding in opposite directions from one another. Passive structures do not actively produce motion: reaction to motion that segments of bone creates. Rate dependant loading: mechanical properties depend on loading rate. Ultimate stress and strain (i. e. strength) is higher for fast loading than for slow. Ligaments: attach articulating bones to one another across a joint, function. Act as positional sensory for joint proprioception: have a crimped appearance angled obliquely. No sharp boundary b/w tendon and muscle aponeurosis is a mix of both muscle and tendon. Attach via tapered weaving (not flat) increased contact area: functions. Provide for optimal contractile conditions: arreantged in dense-parallell fibered collagenous tissues.
