2The Skeletal System4Lesson 4.1: Bone as a Living Tissue Lesson 4.2: The Axial Skeleton Lesson 4.3: The Appendicular Skeleton Lesson 4.4: Joints Lesson 4.5: Common Injuries and Disorders of the Skeletal System
3Chapter 4: The Skeletal System Lesson 4.1Bone as a Living Tissue
4Bone as a Living Tissue functions of the skeletal system structures and classifications of bonesgrowth and development of bonesremodeling of bones
5Functions of the Skeletal System supportbody frameworkprotectionsurround organsmovementmuscles pull bonesstoragemineralsblood cell formationred bone marrow in medullary cavity
6Structures and Classifications of Bones composition of bonesosteocytes–mature bone cellsorganization of bonescorticaltrabecular
25The Intervertebral Discs located between vertebraeshock absorbersallow flexibility
26The Thoracic Cage sternum ribs manubrium body of the sternum xiphoid processribstrue ribsfalse ribsfloating ribs
27Review and Assessment True or False? 1. All ribs are true ribs. 2. The facial bones surround the brain.3. The sphenoid bone is part of the cranium.4. There are 4 regions in the spine.5. Intervertebral discs allow spinal flexibility.
29The Upper Extremity the shoulder complex the arm scapula clavicle humerusradiusulna
30The Upper Extremity the wrist and hand carpals (8) metacarpals (5) phalanges (14)
31The Lower Extremity the pelvic girdle the leg ilium ischium pubis femurtibiafibulapatella
32The Lower Extremity the ankle and foot tarsals (7) metatarsals (5) phalanges (14)
33Review and AssessmentFill in the blanks with: foot, shoulder complex, humerus, or pelvic girdle. 1. The proximal bone of the arm is the _______________. 2. The tarsals are found in the _______________. 3. The scapula and clavicle make up the _______________. 4. The ilium is part of the _______________.
46Common Joint Injuries sprains dislocations bursitis torn ligament or tendondislocationsbone displaced from socketbursitisinflammation of bursae
47Arthritis rheumatoid arthritis osteoarthritis immune system attacks jointsosteoarthritisdegeneration of articular cartilage
48Review and Assessment True or False? 1. A torn ligament causes a sprain.2. Low strength bones easily break.3. Immune system attack causes amenorrhea.4. Greenstick is a type of fracture.5. Bursitis is an inflammation of bursae.
