Lesson ObjectivesUpon 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.
Lesson ObjectivesExplain various types of joints and
body movements.Describe the axial skeleton.Describe the appendicular skeleton.
Skeletal System206 bones, PLUS cartilage, and ligaments
Divided into two systemsAxial skeleton
skull and the vertebral system
Appendicular skeletonextremities
Axial skeleton
Appendicular skeleton
Anterior and Posterior Human Skeleton
Six Main Functions of Bones
1. shape, support
2. protection for organs
3. storage place for mineral salts, calcium, and phosphorus
4. formation of blood cells
5. attachment of skeletal muscle
6. movement possible
Name them bones

JointsThe positioning of the bones at the joint determines the type of movement
synarthrotic joint has no movementAmphiarthrotic joint allows for limited movement
A diarthrotic joint allows for free movement
synarthrotic joint
Amphiarthrotic joint
diarthrotic joint
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
Body Movements Allowed by the Diarthrotic Joint Extension –straightening a flexed limb
Flexion –bending (or curving) the spine
Inversion-- turning inwardPronation –lying prone or face down: or turning the hand so that the palm points downward
Protraction –moving a body part forward
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
Fill in Cloze
Tendons and LigamentsLigaments – connect bone to bone
Tendons – Connect muscle to bones

The Vertebral Column
Divided into 5 regions:Cervical vertebrae
Thoracic vertebrae
Lumbar vertebraeSacrum Coccyx
The Rib Cage
ribs acts to form a protective cage that houses the heart, lungs
Consists of 12 pairs of ribs
