Femur bone classification?
Long bone
Tarsal bone classification?
Short bone
Cranial bone classification?
Flat bone
Vertebrae bone classification?
Irregular bone
Tough sheath covering outer surface of bone?
Periosteum
Covers all internal surfaces of bone within medullary cavity?
Endosteum
Osteoblast function?
Form new bones and add growth to existing bone tissue
Osteoclasts function?
Dissolve old and damaged bone tissue (so it can be replaced with new, healthier cells created by osteoblasts)
Rigid connective bone tissue that appears white, smooth, and solid. Makes up about 80% of bone mass
Compact bone
Internal to compact bone, appears porous and makes up about 20% of total bone mass
Spongy bone
Semi rigid connective tissue that is more flexible than bone
Cartilage
Function/location of hyaline cartilage
attaches ribs to sternum (costal cartilage), covers the ends of some bones (articular cartilage), and is the cartilage within growth plates (epiphyseal plates).
Function/location of fibrocartilage
A weight bearing cartilage that can withstand compression. Forms the intervertebral disks, pubic symphysis, and cartilage pads of knee joints.
Dense regular connective tissue that anchors bone to bone.
Ligaments
Dense regular connective tissue that connects muscles to bone.
Tendons
What is Hematopoiesis?
The process of blood cell production. It occurs in red bone marrow connective tissue, containing stem cells that form blood cells and platelets.
Calcium function
Essential mineral for muscle contraction, blood clotting, and release of neurotransmitter from nerve cells
Phosphate function
Structural component of ATP, other nucleotides and phospholipids, and important component of plasma membrane
Diaphysis
Shaft of a long bone
Medullary cavity
Hollow cylindrical space within the diaphysis. In children the cavity contains red bone marrow, that is replaced by yellow bone marrow in adults.
Epiphysis
A expanded, knobby region at each end of a long bone. Can be proximal epiphysis or distal epiphysis.
Articular cartliage
thin layer of hyaline cartilage covering the joint surface of an epiphysis
Metaphysis
region of a long bone where the bone widens and transfers forces between diaphysis and epiphysis
Red bone marrow function
Forming blood cells in the body
