Bone Classification
There are this many bones in the adult human body, but more in infants and children.
This bone structure has open spaces and is found in the epiphyses of long bones.
What is spongy bone?
What is an osteon?
Both types of fetal bone development, Intramembranous and Endochondral, fall under this umbrella term for bone formation.
What is ossification?
This is the proper name for blood cell formation within the bones.
What is hematopoiesis?
The function of the skeletal system is for five reasons [name one].
What are movement, protection, support, mineral storage, hematopoiesis?
This bone structure can be either the site of hematapoiesis, or the storage of fat.
What is bone marrow (red=hematopoiesis, yellow=fat storage)?
This bone structure supplies the scaffolding for spongy bone.
What are trabeculae?
This vitamin is required for proper osteoclast and osteoblast activity.
What is Vitamin A?
This is the most common salt within bones.
What is calcium phosphate?
This type of bone acts as a lever when a muscle contracts, and includes bones like the metacarpals and the tibia.
What is a long bone?
This bone structure enters the long bones through a foramen, allowing nourishment to pass through and keep the bone healthy.
What is the nutrient artery?
This structure is found surrounding trabeculae, and lining the medullary cavity.
What is the endosteum?
Osteoclasts and osteoblasts team up every year and remodel around this much bone.
What is 5-10% of the skeleton?
As an adult, red marrow is still found in these bones. [name two]
What are the skull, sternum, clavicles, vertebrae, femur, and pelvis?
This type of bone protect tendons and are small and round; some people have extra bones of this type.
What is a sesamoid bone?
This bone structure is the site of growth during youth, and will eventually be replaced by bone when done growing.
What is the epiphyseal line?
These structures run through the central canal of compact bone. [name one]
What are blood vessels, lymph vessels, and nerves?
These factors influence bone development and repair. [name one]
What are nutrition, sunlight exposure/Vitamin D intake, hormone secretions, and physical activity?
Yellow marrow stores fat, but it can also use stems cells to become these types of tissue. [name one]
What are cartilage, fat, or bone cells?
This type of bone includes the vertebrae and the sinuses, and are known for their function being dependent on their structure.
What is an irregular bone?
The articular cartilage of long bones is made up of this specific type of cartilage.
What is hyaline cartilage?
This type of bone cell can differentiate into osteoblasts, and are found in the periosteum and the endosteum.
What is an osteogenic (stem) cell?
This is the first step in the proper healing of a bone fracture.
What is the formation of a blood clot/hematoma at the fracture site?
The management of the raising and falling of calcium ions within the blood is this type of mechanism.
What is a negative feedback loop?
