Sample Question
Which of the following statements regarding thoracic vertebrae is false?

Thoracic vertebrae T9 to T12 have only a single costal facet on each side.

Ribs 1-10 contact their thoracic vertebrae at two points: a costal facet and a transverse costal facet.

Thoracic vertebrae T1 to T8 have superior and inferior costal facets, as they articulate with two pairs of ribs.

The transverse processes of T1 to T10 are relatively thick, and their dorsolateral surfaces contain transverse costal facets for articulation with rib tubercles.

Sample Question
What are the body fluid compartments, their measurements, and composition?

TBW%: M:70 F:40%, ECF: 15%, ICF: 45%, Major cations: Cl-, K+, Major anions: Na+, CO2

TBW%: M:40 F:30%, ECF: 25%, ICF: 35%, Major cations: H+, Ca2+, Major anions: Mg2+, SO4

TBW%; M:60 F:50 % ECF: 20% , 14 l = interstitial fluid + plasma -Intravascular (blood plasma, lymph) - 5% -Extravascular - Interstitial - 15% (ultrafiltrate of plasma - less proteins) Major cation: Na´+ , Anions: Cl-, HCO3- F= fluid from which cells take up O2 and nutrients and discharge metabolites into ICF: 40% - 28L (2/3) Major cations: K+, Mg+ anions: Protein, organic phosphates ECF vs. ICF Na+: EC; 142 IC: 9 K+: E; 5 , I:135 Cl-: E:103, I: 9 -Seperated by membranes -Permeable to water, but not so much to solutes Na+, Cl- , conc. of these = effective osmolarity for each compartment -ECF effective osmolarity increase, cell shrink (ICF decrease) + vv. Interstital fluid vs plasma fluid -Fluid moves across capillary membranes -Freely permeable to all plasma substances except proteins = plasma protein conc. determine effective osmolarity ECV vs. ICV -ECV; Enlarge with net gain of body fluid, (decrease with net loss) -ICV: Varies with effective osmolarity of EC-compartment, (increase osmolarity -> decrease ICV) Measurements: Dilution method -Triated water: Total body water -Mannitol: ECF -Evans blue: plasma volume Conc. in plasma measured, Volume = amount of substance present/ conc. in plasma

TBW%: M:50 F:60%, ECF: 30%, ICF: 20%, Major cations: Ca2+, Mg2+, Major anions: HCO3-, PO4
