Tissue
This is the precursor to compact bone:
cartilage
Which organ did we discuss as a blood reservoir? What does this mean?
Integumentary
The skull develops with this method:
Intramembranous ossification
concentric rings making up the functional unit of compact bone
lamellae
This layer of skin is dead
lucidum or corneum
This covers the ends of bones at movable joints (articular surfaces):
hyaline cartilage
Which organ that we have discussed is important for mineral storage? What is the important mineral?
Ca++
Where do osteoblasts that lay down bone in endochondral ossification come from?
Invading blood vessels
these cells create all other bone cells
osteogenic cells
This type of fracture is when bone is crushed
compression
This layer of the skin is the most superficial vascularized layer
papillary dermis - loose areolar CT
Besides acting as a supportive framework and storing minerals, list 2 other functions of bone:
protection
anchorage
blood cell formation
triglyceride storage
hormone production
All CT including bone arise from this embryonic tissue, or these cells:
mesenchyme/mesenchymal cells
these cells break down bone
osteoclasts
This hormone is released when blood Ca++ is low
PTH - parathyroid hormone
One example from skin and one example from muscle. This layer is composed of dense irregular CT.
Reticular dermis
Outer fibrous layer of the periosteum
Outside of being a blood reservoir, the skin works closely with the vascular system to produce two functions. Explain.
Temp regulation - vd/vc
Excretion - sweat is filtered blood
List the epiphyseal plate layers from epiphysis towards diaphysis and give a brief description:
Resting zone
Proliferation zone
Hypertrophic zone
Calcification zone
Ossification zone
the flared portion of bone between the shaft and ends
metaphysis
Three examples of Wolff's Law
Long bones thickest around the diaphysis.
Handedness
Curved bones thickest where buckle
trabeculae from trusses at lines of stress
projections at muscle attachments
List the 3 type of glands found in skin and give a brief description of their product.
Eccrine - water; electrolytes; waste
Apocrine - Eccrine + fatty protein substance
Sebaceous - oil; sebum
Skin is protective. What are the 3 types of protection is provides and give an example of each:
Physical - brick and mortar keratin/glycolipid
Biological - dendritic cells; macs
List two similarities and two differences in long bone development and bone repair.
Per instructor
these fibers connect the periosteum to bone
Sharpey's/perforating
The skin is an organ. What tissues does it consist of and give me an example of each tissue type.
epithelial - keratinocyte layers
CT - papillary and reticular dermis
nervous - touch receptors
muscle - arrector pili muscles or smooth muscle associated with bvs
