The Skeletal System Lesson 1:
2
Lesson Objectives Upon completion of this lesson, students should be able to … List the various types of bones in the body. Identify specific bones for each bone classification. Discuss the functions of the bones of the human skeleton.
3
Lesson Objectives Explain various types of joints and body movements.
Describe the axial skeleton. Describe the appendicular skeleton.
4
Skeletal System 206 bones, PLUS cartilage, and ligaments
Divided into two systems Axial skeleton skull and the vertebral system Appendicular skeleton extremities 4

Six Main Functions of Bones
10
1. shape, support
11
2. protection for organs
12
3. storage place for mineral salts, calcium, and phosphorus
13
4. formation of blood cells
14
5. attachment of skeletal muscle
15
6. movement possible
16
Name them bones CLICK Here
17
Joints The positioning of the bones at the joint determines the type of movement synarthrotic joint has no movement Amphiarthrotic joint allows for limited movement A diarthrotic joint allows for free movement
18
synarthrotic joint
19
Amphiarthrotic joint
20
diarthrotic joint
21
Body Movements Allowed by the Diarthrotic Joint
Abduction – movement away from the midline Adduction – movement toward the midline Circumduction –moving a body part in a circular motion Dorsiflexion –bending a body part backward Eversion – the process of turning outward
22
Body Movements Allowed by the Diarthrotic Joint
Extension –straightening a flexed limb Flexion –bending (or curving) the spine Inversion-- turning inward Pronation –lying prone or face down: or turning the hand so that the palm points downward Protraction –moving a body part forward
23
Body Movements Allowed by the Diarthrotic Joint
Retraction –moving a body part backward Rotation –moving a body part around a central axis Supination –lying supine or face upward; also the process of turning the palm or foot upward

25
Tendons and Ligaments Ligaments – connect bone to bone
Tendons – Connect muscle to bones
26
Bones of Axial the Skeleton
Skull Cranium Face Sternum Ribs Vertebrae Sacrum Coccyx 26
27
The Vertebral Column Divided into 5 regions: Cervical vertebrae
Thoracic vertebrae Lumbar vertebrae Sacrum Coccyx 27
28
The Rib Cage ribs acts to form a protective cage that houses the heart, lungs Consists of 12 pairs of ribs
29
Bones of the Appendicular Skeleton
Upper extremities Lower extremities Pectoral girdle Pelvic girdle 29
30
Bones of the Upper Extremities
Clavicle Scapula Humerus Ulna Radius Carpals Metacarpals Phalanges 30
31
Bones of the Lower Extremities
Femur Patella Tibia Fibula Tarsals Metatarsals Phalanges 31
32
Critical Thinking Questions
How can you remember the difference between the ulna and the radius?
