skeletal Flashcards
what are the 2 component of the skeletal system
cartilage and bone
which is the most abundant cartilage: hyaline, fibro or elastic
hyaline
what are the 5 classifications of bone
long, short, irregular, flat and sesamoid
name where you’d find a long bone
finger
name where you’d find a short bone
foot
name where you’d find an irregular bone
vertebrae
name where you’d find a flat bone
skull
name where you’d find a sesamoid bone
patella
name the 5 major functions of bone
mineral storage, hormone storage, blood cell formation, triglyceride storage and hormone production
name the 3 different osteogenic cells found in the bone
osteoclast, osteoblast and osteocytes
what is the role of an osteoblast
to produce bone matrix and calcium binding proteins
what is the role of an osteoclast
remove bone tissue and remodel bone with enzymes
what is the role of an osteocyte
to sit in lacunae and help with maintenance and recycling materials and waste
what is the periosteum layer of the bone
tough protective structural membrane
what are the 2 layer of the periosteum
osteogenic layer and fibrous layer
structure of osteogenic layer in periosteum
cambium cells
structure of fibrous layer in periosteum
tough membrane, tight connected to bone by sharpie fibres
How are tendons and ligaments connected
they attach to the periosteum layer and then the sharpie fibres attach it to the bone itself
what name is given to the layer of the bone that is made of delicate connective tissue
endosteum
what are the structures and functions of the endosteum
contains osteogenic cells - lining canals passing through and also the internal surface of compact bone
what is the use of yellow bone marrow
fatty resource
the structure of spongey bone
open network of trabeculae with no osteons - still remains strong and calcified however the density depends on strain applied.
what are the 2 types of canals in bone called
Haversian and caniculi
what does the Haversian canal do
this hold the blood vessels and nerves running through the bone
