Connective Tissue
Chapter 4
Bone
(compressive)
Cells - 10%
Osteocytes
- most abundant - exchange nutrients and wastes with blood
Osteoclasts
- break down and clear away extracellular matrix
Osteoblasts
- secrete collagen
Organic material - 10% - Collagen - tensile strength
Inorganic material 60% - mineral salts - rigidity
Water 20%
Cartilage
(compressive)
Elastic - most pliable - ears, nose
Fibrocartilage - toughest - discs, meniscus, labrum
Hyaline - articular - most abundant - end of bones
Fascia
(tension)
Proper fascia (sheets)
Layers
Perimysium - each bundle of fibers
Endoymsium - each muscle fiber
Epimysium - entire muscle
Fascia profunda - entire body segment
Divisions
Muscle envelope - groups of muscles
Septum - muscles of the extremities
Aponeurosis - broad, flat tendon/stability
Interosseous membrane - between bones
Retinaculum - ankles & wrists
Joint capsule
