Bones Generally
The skeletal system is said to provide six primary functions, among them are support, shape and leverage. The other three are.
What are mineral storage, RBC production and protection.
The bones of the spinal column are known as
What are VERTEBRA.
Osteocytes, which are the mature bone cells that maintain bone matrix, are found living in one of these.
What are LACUNAE.
The main type of cell responsible for bone growth, is known as this.
What is an OSTEOBLAST.
The breakdown of bone is considered this type of chemical reaction.
What is CATABOLIC
The long, central shaft of a long bone is known as its.
What is DIAPHYSIS
The vertebra, the bones of the spinal column, are classified as this type of bone.
What are IRREGULAR bones.
The layers of the bone matrix, are known as.
What are LAMELLAE.
This type of activity causes osteoclasts to build bone.
What is WEIGHT-BEARING EXERCISE.
This term describes the dissolving of bone matrix.
What is RESORPTION or OSTEOLYSIS
This unmatured (non-calcified) form of matrix is produced by osteoblasts.
What is OSTEOID.
Flat bones, that form into broad, flat plates, can be found in one of these three places.
What is the CRANIUM, the ILIUM (the pelvis), andd the STERNUM (and the rib cage).
These mature bone cells maintain the bone matrix.
What are OSTEOCYTES.
Calcium phosphate reacts with calcium hydroxide to form crystals of this bone forming chemical
What is HYDROXYAPATITE (Ca10(PO4)6(OH)2).
Osteoclasts, in order to facilitate bone breakdown, secretes these two substances.
What are ACIDS and PROTEIN-DIGESTING ENZYMES.
Spongy bone, which is highly vascularized and creates red bone marrow, can also be referred to as this.
What is CANCELLOUS BONE or TRABECULAR BONE.
Bones that form as a result of large pressures within a joint due to forces of a tendon are known as this.
What are SESAMOID BONES (small round bones).
This protein, excreted by osteocytes, inhibits osteoblast activity and stimulates osteoclast activity.
What is SCLEROSTIN.
These Mesenchymal stem cells divide to create new bone producing cells during fracture repair.
What are Osteoprogenitor cells.
This chemical form in osteoblasts and leads to osteoclast formation, differentiation, activation and survival.
What is RANKL.
There are three hormones that are said to maintain homeostasis in bones, they are known as.
A patient reports a dull, lonstanding pain beneath the big toe joint. This patient is likely suffering from this.
What is SESAMOIDITIS.
The outside of Compact Bone, once completely grown, is covered with an outer membrane known as this.
What is PERIOSTEUM.
Cytoplasmic extensions that form in the lamellae and connect areas of bone are known as.
What is CANALICULI.
This chemical, secreted by osteoblasts, protects the skeleton from excessive bone resorption.
What is OSTEOPROTEGERIN.
