2 The Basic Functions of the Skeletal System Hematopoiesis Structure Support Muscle Attachment and Movement Mineral Storage Hematopoiesis Structure Support Muscle Attachment and Movement Mineral Storage

3 Axial vs. Appendicular The Axial Skeleton –Contains the bones that are along the long axis of the body, or the bones of the head and trunk The Appendicular Skeleton –Contains the bones of the extremities (or appendages) –Includes the pectoral girdles, pelvic girdles, and the bones of the arms and legs The Axial Skeleton –Contains the bones that are along the long axis of the body, or the bones of the head and trunk The Appendicular Skeleton –Contains the bones of the extremities (or appendages) –Includes the pectoral girdles, pelvic girdles, and the bones of the arms and legs

4 Bones of the Cranium Frontal Parietal Occipital Temporal Maxillae Mandible Frontal Parietal Occipital Temporal Maxillae Mandible

5 Frontal Bone Forms the forehead Forms the roof of the eye sockets Forms the forehead Forms the roof of the eye sockets

6 Parietal Bones Consists of two bones Forms the sides and roof of the cranial cavity Consists of two bones Forms the sides and roof of the cranial cavity

7 Temporal Bones Consists of two bones Forms the lower sides of the cranium and part of the cranial floor Consists of two bones Forms the lower sides of the cranium and part of the cranial floor

8 Occipital Bone The base of the cranial cavity Prominent posterior portion The base of the cranial cavity Prominent posterior portion

9 Maxillae The upper jaw

10 Mandible Lower jaw bone

11 The Vertebral Column Composed of 33 bones Encloses and protects the spinal cord Supports the head Composed of 33 bones Encloses and protects the spinal cord Supports the head

12 Bones of the Vertebral Column Cervical Vertebrae—7 bones located in the neck Thoracic Vertebrae—12 bones connected to the ribs Lumbar Vertebrae—5 bones in the lower back Sacral Vertebrae—5 pelvic bones Coccygeal Vertebrae—4 tailbones Cervical Vertebrae—7 bones located in the neck Thoracic Vertebrae—12 bones connected to the ribs Lumbar Vertebrae—5 bones in the lower back Sacral Vertebrae—5 pelvic bones Coccygeal Vertebrae—4 tailbones

13 Vertebral Curvatures

14 Bones of the Thoracic Cavity Sternum Xiphoid Process Ribs Sternum Xiphoid Process Ribs

15 Bones of the Upper Extremities Humerus Radius Ulna Carpals Metacarpals Phalanges Humerus Radius Ulna Carpals Metacarpals Phalanges

21 Joints Where two bones articulate The points of contact between bones –Hinge Joints –Gliding Joints –Ball and Socket Joints Where two bones articulate The points of contact between bones –Hinge Joints –Gliding Joints –Ball and Socket Joints

22 Hinge Joints Allows for extension and flexion

23 Gliding Joints Bones slide past each other

24 Ball and Socket Joints Allows for rotational movement in almost any direction

25 Disease and Disorders Fractures Scoliosis Kyphosis Lordosis Osteoarthritis Fractures Scoliosis Kyphosis Lordosis Osteoarthritis

26 Fractures Types of fractures –Closed or simple fracture The bone is broken and the skin is intact –Open or compound fracture The bone is broken and the skin is cut by the bone Types of fractures –Closed or simple fracture The bone is broken and the skin is intact –Open or compound fracture The bone is broken and the skin is cut by the bone

28 Scoliosis Abnormal lateral curvature of the spine

29 Kyphosis and Lordosis Kyphosis- abnormally enlarged thoracic curve (humpback) Lordosis- abnormally enlarged lumbar curve (swayback) Kyphosis- abnormally enlarged thoracic curve (humpback) Lordosis- abnormally enlarged lumbar curve (swayback)

30 Osteoarthritis Arthritis that is caused by the breakdown and loss of cartilage in the joints
