to talk about bones we must look at their:
2. feature surface markings

sutural bones are basically…
small bone chips
which bones are small, flat, develop inside of the tendons, are near joints, and vary in number and location?
what is the one sesamoid bone pair that does not vary in shape and location from person to person?

vertebrae, pelvic bones, some skull bones
which bones are small and boxy?
where can you find short bones?
carpals and tarsals
which bones have thin, parallel surfaces, serve as protection for underlying soft tissues, provide surface for muscle attachment?
where can you find flat bones?
skull, sternum, ribs, scapulae
which bones are long, slender, in appendages?
where can you find long bones?
femur, humerus, metacarpals/tarsals, radius, etc.
which bone shape includes the larges bone of the body?
what are some characteristic internal and external features of bone markings?
large rounded projection; may be roughened
narrow ridge of bone; usually prominent
very large, blunt, irregularly shaped process
narrow ridge of bone; less prominent than a crest
small rounded projection or process
raised area on or above a condyle
sharp, slender, often pointed projection
any bony prominence
bony expansion carried on a narrow neck
smooth, nearly flat articular surface
rounded articular projection
armlike bar of bone
narrow, slitlike opening
round or oval opening through a bone
indentation at the edge of a structure
cavity within a bone, filled with air and lined with mucous membrane
shallow, basin like depression in a bone, often serving as an articular surface
what are the 2 types of bone structure?
which type of bone structure is dense, relatively solid, and forms a sturdy, protective layer surrounding a medullary cavity (marrow cavity)?
which type of bone structure is cancellous/trabecular, open network of struts and plates, thin covering of compact or cortical bone?
true or false. Spongy bone is never exposed to the surface.
what are the 5 typical structures of a long bone?
4. medullary cavity
the long shaft in the long bone
the head at the end of a long bone
the neck; where the epiphyses attaches to the diaphysis in a long bone
membrane inside the medullary cavity of a long bone
double layered connective tissue that covers and nourishes the bone
except in joints
supporting connective tissue contains...
extracellular protein fibers
bone matrix contains ________ salts
uncalcified bone matrix
small open space in the matrix
small holes that allow for the exchange of materials
how many osteocytes are inside of a lacunae?
true or false. the matrix in the spongy bone is the same as the matrix in the compact bone.
in spongy bone, about how much of the mass do the cells account?
what kind of fibers provide framework in spongy cells?
what is unique about spongy bone?
it can repair itself
what are the four types of bone cells?
3. osteoprogenitor cells
which type of bone cells are mature, occupy lacuna surrounded by lamellae, cannot divide, and are canaliculi?
layers of calcified matrix
what are the 2 major functions of osteocytes?
1. maintain protein and mineral content of matrix
2. participate in repair of damaged bone
which type of bone cells produces asteroids, and elevates Ca phosphate levels above solubility limit?
osteoblasts calcify themselves into _________.
osteocytes are __________ surrounded by _______.
which type of bone cells are squamous stem cells, daughter cells differentiate into osteoblasts, important in fracture repair, and inner layer of periosteum and endosteum
which type of bone cells remove and recycle bone matrix, are giant cells with 50+ nuclei, are derived from stem cells that produce monocytes
osteoblasts are ____________ bone mass while osteoclasts are ___________ bone mass
matrix-synthesizing cell responsible for bone growth
mature bone cell that monitors and maintains the mineralized bone matrix
