Untitled Flashcards Set

Overly simplified box model of the body – What does this represent?  How is anatomy involved with the construction of this model?

Homeostasis

Negative feedback

Positive feedback – How does this differ from negative feedback?  Which feedback loop component does a positive feedback loop have that a negative loop does not?

Set point

Error signal

Body Mass Index (BMI) – How is this derived?

Diabetes – what are the signs and symptoms?

Diagnosing Diabetes – various tests (know the time frames and levels associated for these tests)

Body Fluids

Total Body Water

Body fluid compartments

Passive transport Vs. Active transport – It would be good to look at the table in your text that pertains to this.

Chemical Driving Force – Is this positive or negative?  What does it mean if there is a positive or negative value?

Membrane permeability – How can a membrane be selectively permeable?  What factors are involved?  What crosses easily?  What does not cross?

Membrane potential – How is this calculated?

Chemical and electrical forces

Equilibrium Potential – What does this value represent?

Sodium/Potassium pump – How does this work?  What is this responsible for?

Glucose transport

Simple Diffusion

Facilitated Diffusion

Primary and Secondary Active Transport

Osmosis

Osmolarity – iso, hypo, hyper

Tonicity

Endocytosis

Exocytosis

Transcytosis

Paracrine chemical messenger

Lipophobic ligands / Lipophilic ligands – How do these differ?

Chemical Classification of Messengers

Messenger half-life

Receptor Binding and Properties – Affinity

Transport proteins

Magnitude of Target Response

Up-regulation & Down-regulation

Agonists and Antagonists

G Protein–Coupled Receptors - Study this in your course text.

Second Messenger Systems – What is the function of a second messenger system?  Study this in your course text.

Signal Amplification

Endocrine

Primary Endocrine Organs (Hypothalamus, Pituitary gland, Pineal gland, Thyroid gland, Parathyroid glands Thymus, Adrenal glands, Pancreas, Gonads) – The hormones and functions of these organs.

How do secondary endocrine organs differ from primary endocrine organs?

Regions of the adrenal gland and what is produced (or released) from each region.

Abnormal Secretion of Hormones

Hormone Interactions
