Bone Basics
The scapula is part of this division of the skeletal system.
What is the appendicular skeleton?
Cell that lives in the lacuna
What is an osteocyte?
Joints that are immovable or only slightly movable.
What are fibrous and cartilaginous joints?
First thing that forms at the site of a bone fracture.
What is a hematoma?
This bone forms the back and base of the skull.
What is the occipital bone?
The frontal bone is this type of bone.
What is a flat bone?
This type of bone has trabeculae and contains red marrow.
What is spongy bone?
This type of synovial joint allows the greatest range of motion.
What is ball & socket joint?
Blood calcium drops and this hormone will trigger the release of calcium into the blood from the bones.
What is parathyroid hormone?
Tough outer covering surrounds a bone
What is periosteum?
The ends of a long bone
What are epiphyses?
This bone cell breaks down bone tissue to release calcium into the blood.
What is an osteoclast?
This structure connects bone to bone.
What is a ligament?
This type of fracture is incomplete and common in children.
What is a greenstick fracture?
This type of bone marrow stores fat.
What is yellow bone marrow?
This mineral makes bones hard and provides the ability to resist compression.
What is hydroxyapatite?
Tiny canals in bone tissue that connect osteocytes.
What are canaliculi?
Fluid that reduces friction at a joint.
What is synovial fluid?
Long bone grows from this point in children.
What is the epiphyseal plate?
The five sections of the vertebral column from superior to inferior.
What is the cervical, thoracic, lumbar, sacrum, and coccyx?
Process where minerals are deposited into cartilage to turn it into bone
What is ossification?
Rings of lamellae and osteocytes make up this struture
What is an osteon?
Bones involved at the elbow hinge joint.
What are the radius, ulna, and humerus?
Four main steps of bone repair in order.
What is Hematoma → Fibrocartilage callus → Bony callus → Bone remodeling?
Two differences between the bones of infants and adults.
Infants: more cartilage, unfused epiphyses
Adults: fused bones, less cartilage
