1 Warm-upCreate a “word splash” of what you know about bones. Think of as many words as possible and write them down.
2 What is the purpose of our skeletal system? LEQWhat is the purpose of our skeletal system?
3 The Skeletal System Parts of the skeletal system Bones (skeleton) JointsCartilageLigaments (bone to bone) (tendon= bone to muscle)
4 The Skeletal SystemSkeleton comes from a Greek word meaning dried up body.Bone appears dead and dried up, but it is not!Bone is living tissueNewborn human has 350 bonesAdult human has 206 bones
5 Changes in the Human Skeleton In embryos, the skeleton is primarily hyaline cartilageDuring development, much of this cartilage is replaced by boneCartilage remains in isolated areasBridge of the noseParts of ribsJoints
6 Structure and Function • Functions of the skeletal systemProvides shape and supportProtects internal organsStores minerals and fatProduces blood cells and plateletsAssists in movementLook at page 193
7 The Two Skeletons Axial skeleton Includes the 80 bones of the head and trunkAppendicular skeletonIncludes the 126 bones of the pelvis, shoulders, arms, and legs
10 Classification of Bones Long bonesTypically longer than wideHave a shaft with heads at both endsContain mostly compact boneFound in legs and armsExamples: Femur, humerusPage 193. Read about epiphysis and diaphysis.
11 Classification of Bones Short bonesGenerally cube- shape and smallContain mostly spongy boneFound in wrist, ankles, and toesExamples: Carpals, tarsals
12 Classification of Bones Flat bonesThin and flattenedUsually curvedCover organs/provide surface for lg. muscleThin layers of compact bone around a layer of spongy boneExamples: Skull, ribs, sternum
13 Classification of Bones Irregular bonesIrregular shapeDo not fit into other bone classification categoriesExample: Vertebrae and hip, ear and face bones
14 Sesamoid Bones Sesamoid bones Small and usually embedded in tendons, used to protect integrity of tendonsPatellaSome in hands and feet
21 The Skull (28 bones) (18 names!) Sits on top of the vertebral columnTwo sets of bonesCranium (8 bones)Facial bones (14 bones)Bones are joined by suturesOnly the mandible is attached by a freely movable joint
54 The Cranium That’s it! No more cranium bones! 206 bones - 8 bones = 198 bones to go…
55 Activity!You and a partner will create a rap/song of what you’ve learned about the bones so far.You can include types of bones, names, etc.Doesn’t have to rhymeMust be 20 linesKeep it appropriateEveryone will perform. The top group gets extra credit!
56 What are the bones in the face? LEQWhat are the bones in the face?
57 Answer the LEQ from yesterday. Let’s finish the raps from yesterday.Warm-up
58 What are the different sections of the spinal column? LEQ
59 Facial Bones 14 bones Most of these bones come in pairs Only the mandible and vomer are single bonesFacial Bones
69 Facial Bones That’s it! No more facial bones! 198 bones - 14 bones = 184 bones to go…Facial Bones
70 The Vertebral Column The backbone or spine Consists of 26 bones called vertebraeThe Vertebral Column
71 The Vertebral ColumnVertebrae separated by intervertebral discs (act as shock absorbers)The spine has a normal curvatureEach vertebrae is given a name according to its locationFigure 5.14
72 Vertebral column C1-C7 ~ in the neck region 7 cervical vertebraeT1-T12 ~ located in the chest region12 thoracic vertebraeL1-L5 ~ located in the lower back5 lumbar vertebraeVertebral column
73 Sacrum ~ curved bone of the lower back (posterior wall of the pelvis) Fused sacral vertebrae5 vertebrae at birthCoccyx ~ the tailbone4 vertebrae at birthVertebral column
74 The Bony Thorax (Thoracic Cage) The chest regionForms a cage to protect major organsComposed of sternum, ribs and thoracic vertebrae.Figure 5.19a
75 Thoracic Cage Sternum ~ breastbone Dagger-shaped bone located along the midline of the anterior chestThoracic Cage
76 Ribs ~ 12 pairs of ribs attach posterior to the thoracic vertebrae True ribs ~ first 7 pairFalse ribs ~ last 5 pairsThoracic Cage
77 That is it for the axial skeleton! 154 bones - 24 ribs - 1 sternum = 129 bones to go!!!That is it for the axial skeleton!
78 What are the different sections of the spinal column? Answer LEQ
79 Appendicular Skeleton Bones of theAppendicular Skeleton

One word per note. Split with your partner.
81 What makes up the appendicular skeleton? LEQWhat makes up the appendicular skeleton?
82 The Appendicular Skeleton Limbs (appendages)Pectoral (shoulder) girdlePelvic girdle
83 The Pectoral (Shoulder) Girdle Composed of two bonesClavicle – collarboneScapula – shoulder bladeThese bones allow the upper limb to have exceptionally free movement
93 Bones of the Pelvic Girdle Composed of two coxal bones (hip bones)Composed of three pair of fused bonesIliumIschiumPubisThe total weight of the upper body rests on the pelvisProtects several organsReproductive organsUrinary bladderPart of the large intestineSlide 5.37
128 What are the different types of bone fractures? LEQWhat are the different types of bone fractures?
129 AgendaTake out your body review homework. Make sure your name is on it. I only need the human outline.Review fractures homeworkPick muscle disease projectPick health fair topic/partnersReview with bone bingo
130 Bone Bingo Fill in each blank with a name from the following options. Name of a boneName of a jointType of a fractureAll blanks must be filled in!
