Nutrition

'You have to take responsibility'
Food vs. Nutrients
diet=nutritional status, not a plan
what you're consuming
People talk about cleanses-a cleanse takes 21 days, not quick 3 day thing

Assignment 1 is due in 2wks-the daily food intake form (please include weekend)
Quiz next week too

allergy: immune response (IgE response - a true allergy) Mostly environmental.
sensitivity: IgG, IgA (basically everything else). These are usually ingested with few exception: peanuts, shellfish ...

growing out of something- not really, just less sensitive or different response
grow into something - yes, or develop stronger sensitivity. Ex. latex, gluten

old dairy vs. young dairy

Always eat real butter and lots of it - Dr. Amy
ghee-clarified butter

You earn Type 2 diabetes!
80/20 rule: due the right thing for you 80% of the time

energy = cal. which is ability to do work
nutrients: build/repair body to do work
Nutrition: science of how the body uses food
Energy: ability to do work (every bite give energy, but not necessarily nutrients)
Calories: heat produced when food is burned (metabolism) or raise the temperature of 1 kilogram of water 1degree C at sea level
Nutrients: chemicals your body uses to build, maintain, and repair tissue

Lactos: sugar in milk
70% of the immune system is the digestive tract

Macro nutrients: protein, fats, carbs, water (measured grams and oz.)
micro nutrients: vitamins and minerals (measured in micrograms)

essential nutrients: something body can not make


Psychology
The class is divided in two and I don't know if we'll have the same homework or assignments so nothing will be posted regarding that and I don't know how much can actually be posted for this class.

Anatomy
The Skeletal System-
Axial: the center of the skeleton; skull, spine, ribs, sacrum
Appendicular: everything else

Joint: point of contact between bones
3 types of jt
-fibrous: immoveable (synarthrosis, synarthrotic). No jt cavity, fiberous connective tissue b/w bones - ex. the sutures of the cranial bones
-cartilaginous: slightly moveable (amphiarthrosis, amphiarthrotic). No jt cavity, cartilage b/w bones - ex. pubic symphysis and vertebral jt (discs)
-synovial: freely moveable (diarthrosis, diarthrotic). Have jt cavity, contains synovial fluid.

P. 111 and 108 of Memmlers

Ball and Socket:
mvmt in every plain/direction - transverse, coronal(frontal), sagittal. Ex shoulder (glenohumeral jt). can do circumduction mvmt.

Ellipsoid:
flexion/extention, ab/adduction. Ex wrist (radial carpal jt).

Hinge:
Only flexion/extention. Ex elbow, knee (humeroulnar).

Saddle jt:
like ellipsoid jt. Ex b/w thumb and metacarpal. (only example)

Gliding jt:
small shit b/w bones w/ flat surfaces. Ex carpal bones at wrist, tarsals of foot.

Pivot jt:
allows 1 bone to rotate around another. Ex c1/c2 allow head to turn.


Skin: largest organ, 10% of body weight
Bones: gives structure and allows mvmt
Ligaments: connect bone to bone
Tendon: connects muscle to bone

3 types of muscle (mm) - Memmlers p. 118

Smooth mm:
-located in walls of hollow organs, vessels, respiratory passage ways (lungs, blood vessels, stomach, intestine . . .)
-Cells for smooth mm are tapered at ends, branched, not/non striated
MM contraction is involuntary

Cardiac mm:
-walls of the heart
-cells are branching, special membranes b/w each cardiac cell called intercalated discs, light striations,
MM involuntary contracts

Skeletal MM:
-attaches to bone, allows for mvmt
-cells are long and cylindrical and multi-nucleated, heavily striated, mvmt is voluntary

Muscle (mm) construction (p.11) (from inside out):
Endomysium (endo=inside, myo/mysi=muscle): surrounds individual mm fibers/cells
Perimysium: bundles, or fascicle, of fibers
Epimysium: body of mm, extension of tendon fascia
Periosteum (peri=bone)

We also watched Simply Raw. It covered diabetes and diet.
