NURS 8022 / NURS8022 Exam 4 Study Guide Basics of gastric secretion; what cells secrete what • Gastric juice composition depends on volume & flow rate. Secretion rate lower in AM, higher in PM. Higher K+ in gastric juices.

Guide GI Basics of gastric secretion; what cells secrete what • Gastric juice composition depends on volume & flow rate. Secretion rate lower in AM, higher in PM. Higher K+ in gastric juices. • Inc. gastric emptying – larger volumes of food • Delayed gastric emptying – solids, fats, non-isotonic solutions • Acid – hydrochloric acid (most important acid) o Dissolves food fibers o Bactericide against swallowed organisms o Stimulated by: ACTH, caffeine, Ca2+, gastrin, histam...

Exam 5 Study guide Musculoskeletal Musculoskeletal Physiology Define differences between bone cells Bone Cells About Osteoblasts Bone forming cells. Bone makers. Become osteocytes that are imbedded in bone. Form new bone & synthesize osteoid (un-mineralized portion of bone matrix  mature bone) Osteoclasts Bone resorbing. Bone breakers. They’re attached to integrins by podosomes—which helps bind to bone. Secretes HCl & protease enzyme  resorption of bone (dissolves bone mineral...

Musculoskeletal Define differences between bone cells  Osteogenic cell: stem cell  Osteoblasts: bone forming cells, “bone-builders” o Derived from mesenchymal cells o Produce osteocalcin when stimulated by vitamin D o Form new bone – synthesize osteoid – brings on the formation of new bone – nonmineralized bone matrix o Follow Wolfe’s law: bone is shaped according to its function o Become osteocytes that are imbedded in bone  Osteoclasts: bone resorbing, “bone-cr...
