The 4 projections:
The Medial epicondyles
The lateral epicondyles
The distal epiphysis
What does not have a vertebral foramen?
Sacrum & Coccyx
What does the make up of the scapula, clavicle?
What does the clavicle Articulate with on its distal end?
The clavicle articulates with the acromoin process of the scapula
What articulates proximally with the humerus and radius and dismally with a fibrocartilaginous disk?
What metacarpal forms the most freely?
What form the framework of the hand?
The metacarpal bones are the five bones that make up the framework of the hand?
The pubic arch in males is less than ____degrees?
True or false?
The Pelvic Outlet is an imaginary plane?
What is the inner lining of the medullary cavity?
What cells are responsible for producing organic matrix?
How many cervical vertebrae does the human body have?
How many thoracic vertebrae does the human body have?
How many lumbar vertebrae does the human body have?
What is an example of short bones?
the anterior cranial floor
Medial orbit walls
Upper parts of the nasal septum
Sidewalks of the nasal cavity
Like long bones, flat bones are covered in a periosteum and the inner spaces are lined with?
Are all _______ of _______?
Functions of bone
What is the development of bone from the small cartilage or membrane model into adult bone?
What does the process of appositional growth refer to?
It occurs through the addition of osseous tissue to the outer surface of a flat bone
What do muscle tendon fibers interlace with?
A few layers of bone matrix also run around the outer boundary of compact bone, encircling all the osteosarcoma. These layers that run along the inner circumference (along the endosteum) and outer circumference (along the periosteum) of a bone is called?
Are small cells that synthesize and secrete an organic matrix called osteoid?
Are giant multinucleate cells, that are responsible for the active erosion of bone minerals.
Collagen strands in the osteoid serve as framework for the formation of hydroxyapatite crystals, which mineralized the bone tissue. Osteogenic stem cells, found in the endosteum and lining the central canals, undergo cell division to form?
Formed by the fusion of serial precursor cells and contain large numbers of mitochondria and lysosomes. Erode bone by releasing hydrochloride acid (HC1) that dissolves mineral crystals and collagenase, which is an enzyme that breaks the peptide bonds in collagen proteins. The dissolved mineral ions and amino acids that result from bone erosion are reabsorbed by the bloodstream and recycling for use by fibroblasts, osteoblasts, or other cells of the body.
Responsible for the active erosion of bone minerals?
Are mature, nondividing osteoblasts surrounded by matrix and lying within lacunae
Surround central ( osteoblasts or haversian) canals that run lengthwise through bone and are connected by transverse canals (Volkmann canals)
What cell organelles synthesis organic matrix substances?
Golgi apparatus and ?
