connective tissue
|
elastic, between muscles, SUPPORT

organ
|
tissue of the body with functional use (like a heart)
|
|
|
fascia

|
attach muscle to bone or cartilage- arranged longitudinally. flat muscles- flat tendons, etc.
|
|
|
aponeurosis
|
sheetlike tendon. NOT fascia- much denser- longitudinal (again)
