The Skeletal sysytem

functions of the skeleton 1)Provides a framework that supports the body 2)Protects the internal organs 3)provides storage for excess calcium. Calcium is essential for blood clotting and proper functioning of muscles and nerves 4)contains and protects red bone marrow
spongy bone red bone marrow present
articular cartilage smooth joint surfaces
Periosteum fibrous connective tissue membrane, anchors tendons and ligaments. Have blood vessels that enter the bone
classifications of bones as follows 4 parts
1)Long Arms and legs
2)Short Wrist, ankles (spongy bone covered with compact bone)
Irregular Vertebrae, facial bones (spongy bone covered with compact bone)
Embryonic growth of bone The skeleton is first made of other tissues that are gradually replaced by bone ossification. This begins in the third month of gestation.
Cranial and facial bones First made up of fibrous connective tissue. Bone growth radiates outward
Fontanels soft spots on a baby's head which, during birth, enable the bony plates of the skull to flex, allowing the child's head to pass through the birth canal. Calcified by age two.
Factors affecting bone growth 4 total as follows
1)Heredity Many pairs of genes contribute to genetic potential for height.
2)Nutrition Calcium, phosphorus and protein become part of the bone matrix. Vitamin D is needed for the absorption of calcium in the small intestine. Vitamins C&A are needed for bone matrix production (calcification)
3)Hormones Produced by endocrine glands, energy production
4)Exercise or stress Weight bearing bones must bear weight or they will lose calcium and become brittle
