Bones Anatomy & Physiology
Skeleton System Infant Skeleton about 300 bones Adult about 206 bones
The Skeletal System Supports Protects
Bones make (produce) blood Bone marrow produces blood cells- Blood cells must be reproduced
Bones Important for storage: Stores minerals that are important for your entire body to function, such as: Phosphorus Calcium Potassium, magnesium, zinc and more. What do you mean….are you saying they store stuff?
What else will help to make bones strong? Vitamin D Exercise
Bone Structure Outside: periosteum
Compact bone & Spongy Bone
Bone Marrow Human Bone Marrow Beef Bone Marrow
Why do infants have more bones then adults anyway? Osteoblast- Osteo=Bone, blast=immature Osteoclast osteo=bone, clast= to break
Still Growing- Babies are born with more cartilage
Bones are placed into two groups The axial skeleton forms the central axis of the body. It consists of the skull, the vertebral column, the ribs and the sternum or breastbone
Appendicular skeleton The Upper Extremities The Lower Extremities The Shoulder Girdle The Pelvic Girdle
Rib Bits Called Thoracic Cage- Protects vital organs The rib cage flexes when we breathe
Smallest bones in the body Ear
Sizes and Shapes Long Bones Short Bones Flat Bones Irregular Bones Sesamoid Bones
Arm & Hands
Legs & Feet
Male and Female Skeletons are a bit different Males- slightly thicker, longer legs and arms Females- wider pelvis and larger space, so they can deliver children
Joints 6 kinds of joints in your body There is special fluid in the joints called synovial Hinge Elbow/Knee
Ball and socket joint Shoulder/Hip
Quick Trivia What mineral is important for bone growth and protects from osteoporosis?
Infants have less bones then adults? True or False
False, they have more (Cartilage that turns into bone)
What are the things that are produced in the bone marrow?
Red Blood Cells and Yellow bone marrow, which stores the fats.
What are the 4 functions of the bones?
Supports Protects Produces Stores
Periosteum (pare-ee-os-tee-um). Is located on what part of the bone?
