30
How many bones in the adult human skeleton
206
31
5 functions of the skeletal system
- Supports tissues and provides a framework for our body - Protects organs e.g. rib cage (protects lungs and heart etc.), skull (protects brain) - Reservoir of minerals such as phosphorus and calcium which may be used in time of need (repair and function) - Produces blood cells & platelets - Movement produced by muscles attached to bones by tendons
32
Axial Skeleton
80 bones (skull, vertebral column, thoracic cage) supports and protects organs
33
Appendicular skeleton
126 bones, upper and lower extremities, shoulder and pelvic girdles anchor to the axial skeleton
34
5 types of bones (classification of bones)
Long, short, irregular, flat, sesamoid
35
Periosteum
A fibrous, cellular, vascular and highly sensitive life support sheath covering the length of the bone (not ends). Allows for ligaments and tendons to attach to the bone. (anatomy of long bone)
36
Diaphysis
The shaft or central part of a long bone. (anatomy of long bone)
37
Medullary Cavity
The cavity of the diaphysis that contains red and yellow marrow. (anatomy of long bone)
38
Epiphysis
The ends of the long bone. Outer surface made up of cancellous bone. Articulates (i.e. makes contact) with adjacent bones. (anatomy of long bone)
39
Articular Cartilage
Covers the end (Epiphysis) of the long bone. Smooth, slippery, porous, malleable, insensitive, and bloodless surface that makes contact with adjacent bones. (anatomy of long bone)
40
Nutrient Artery
The principal artery and major supplier of oxygen and nutrients to the shaft of a bone. (anatomy of long bone)
41
Cancellous (Spongy) Bone
Consists of interwoven beams (trabeculae) of bone The spaces are filled with marrow. found inside the bone
42
Compact (Cortical) Bone
Dense bone that forms in the walls of the diaphysis. Provides structural integrity outside of bone (but inside of the bone skin/Periosteum
43
Red Marrow
A gelatinous substance where blood cell formation occurs (red and white).
44
Yellow Marrow
Fatty connective tissue that no longer produces blood cells (with age red marrow becomes yellow).
45
Ossification (bone formation)
begins by the end of the eighth week after conception and continues throughout adulthood
46
Bone remodeling
occurs continuously throughout the lifetime process slows with age the balance of bone breakdown and reconstruction ensures skeletal integrity
47
Key Players in bone formation and remodeling
- Osteocytes: mature bone cells - Osteoblasts: Bone forming/reconstructing cells (osteoblastic activity) Layered over the bone Deposit calcium into the matrix that is building up cortical bone Produce collagen and other proteins to synthesize the bone matrix - Osteoclasts: Cells that break down and reabsorb bone (osteoclastic activity) Imbedded in the bone matrix near the site of reabsorption Dissolve calcium first, then the organic matrix of the bone
48
process of Bone Formation
1. Bones begin as cartilaginous models (8 wks after conception) 2. The periosteum forms around the models 3. Osteoblasts synthesize the compact bone of the diaphysis 4. Cartilage in diaphysis is transformed into cancelous bone as growth continues outward from the center 5. Osteoclasts breakdown cancelous bone to form the medullary cavity
49
What is bone formation?
The process by which our body continually destroys and rebuilds bone tissue throughout our lives.
50
Wolf's Law
Bones will grow or remodel in response to the forces or demands placed on them
51
3 types of joints (articulations)
(classification is based on the presence or absence of a space called a joint cavity) Fibrous – no joint cavity; bones are held together by fibrous connective tissue Cartilaginous – no joint cavity; bones are held together by cartilage Synovial – joint cavity; bones are united by a surrounding articular capsule; accessory ligaments are present
52
Parts/structure of Synovial Joints
Articular cartilage- located on the ends of the bones Joint capsule- synovial membrane and fibrous capsule Joint cavity- filled with synovial fluid (a lubricant for the joint) Bursae- small fluid sacs found at friction points Intrinsic ligaments- thick bands of connective tissue to reinforce the joint capsule Extrinsic ligaments- help to reinforce the joint
53
Types of Synovial joints
Ball and Socket, Ellipsoidal (Condyloid) Joint, Gliding (Plane) Joint, Hinge Joint, Pivot Joint, Saddle Joint
54
Ball and Socket Joint e.g.
Hip socket
55
Ellipsoidal (Condyloid) Joint e.g.
wrist
56
Gliding (Plane) Joint e.g.
ankle
57
Hinge Joint e.g.
elbow joint
58
Pivot Joint e.g.
neck
59
Saddle Joint e.g.
Thumb
60
Parts of the Thorax
ribs, thoracic vertebrae, sternum, and costal cartilages
61
Function of the Thorax
Support: support of the arms and pectoral girdles (shoulder girdles) Protection: protection of the visceral organs in the thoracic and upper abdominal cavities Ventilation: ventilation of the lungs (inspiration (air going in) and expiration (air going out) of air)
62
Parts of the ribs
- Costal Cartilage (The first ten ribs are attached to the sternum by a strip of hyaline cartilage called the costal cartilage. The cartilage of the first 7 pairs of ribs attach directly to the sternum; The cartilage of the 8th through the 10th pairs attach indirectly to the sternum.) - Intercostal Spaces (the spaces between the ribs) - True ribs (1-7), False ribs (8-10), floating ribs (11&12)
63
3 parts of the sternum
Manubrium: the upper portion Body: the middle, largest portion of the sternum Xyphoid Process: the lowest portion of the sternum
64
Parts of the spine
Cervical: 7 vertebrae, support and move the head and neck Thoracic: 12 vertebrae, support head, neck and thorax Lumbar: 5 vertebrae, support upper body, torso and low back Sacrum: 5 fused vertebrae Coccyx: 2-4 tiny individual or partly fused, rudimentary vertebrae
65
3 types of Connective Tissues
Fascia, Ligaments, Tendons
66
*Vascularity*
Amount of blood supplied to a tissue. Vascular = with blood e.g. Bone and Muscle Avascular = without blood e.g. Ligaments and cartilage Generally, increased vascularity means faster recovery from injury. AKA better blood supply means faster recovery
67
3 types of cartilage
Hyaline, Fibrous, Elastic
68
Tendonitis
Inflammation of a tendon caused by irritation due to prolonged or abnormal use
69
Sprains & Tears
Injury to ligaments and tendons
70
Pulls & Strains
Injury to muscle
71
Dislocation
Bone is displaced from its normal location. May also include damage to joint capsule, ligaments, muscle & tendon. E.g. finger, shoulder, etc.
72
Separation (injury)
Ligaments holding a joint together tear and separate from one another
73
Acute Injuries
High Force, awkward posture, low repetition.
74
Chronic injuries
Lower forces, awkward posture, high repetition AKA repetitive strain (RSI)
75
Injury Severity
First degree: Least severe A few days to heal Second degree: Moderate Longer to heal and require special treatment Third degree: Most severe Longest to heal (6 -12 mo) may require surgery
76
Shin Splints
painful condition occurring on the medial or lateral side of the tibia
77
Stress Fracture

78
Osteoporosis
a degenerative bone disease characterized by low bone mass and deterioration
79
Fracture
a full bone break due to extreme loads, impact or stresses
80
Simple/Incomplete Fractures
No separation of the bone into parts A crack or break is usually detectable
81
Compound/Complete Fractures
The bone has been completely fractured through its own width Usually also results in damage to the surrounding soft tissue They are either OPEN (Bone breaks through the skin) or CLOSED (Bone does not break through the skin)
82
Compound Fractures (4 types)
Comminuted Fracture, Spiral Fracture, Avulsion Fracture, Impacted Fracture
83
Comminuted Fracture
The bone is broken into more than two fragments (highly unstable).
84
Spiral Fracture
The bone has been broken due to a twisting type motion and looks like a corkscrew.
85
Avulsion Fracture
A fragment of bone is detached from its point of insertion by a tendon or ligament.
86
Impacted Fracture
One bone fragment is driven into the medullary space or spongy bone of itself or another bone. The ends of the broken bones are wedged together.
