|
towards the side of the body
|
|
|
what direction is the superficial?
|
towards the surface of the body
|
|
|
what direction is "deep"

away from the surface of the body
|
|
|
what direction is proximal?

what is the sagittal plane?
|
vetical plane that divides the body or organ into a right and left side
|
|
|
whats the transverse plane?
|
divides a specimen into a superior and an inferior part
|
|
|
what is the frontal plane?
|
divides specimen into an anterior and posterior section

|
|
what is homeostasis?
|
the body's way of keeping and maintaining a stable internal environment
|
|
|
what is a negative feedback mechanism? What is an example?
|
regulates most homeostatic mechanisms, resist change from a set point and return the system to homeostasis: Blood pressure regulation
|
|
|
what are positive feedbacks? What is an example?
|
not homeostatic, creates a cycle that leads AWAY from homeostasis.:the birthing process

|
Neutron-no electrical charge, found in nucleus||Proton-positive charge, found in nucleus||electron-negative charge, found in energy shells
|
|
|
what are valence electrons?
|
electrons in the outermost shell, canbe transferred or shared between 2 atoms in chemical bonding
|
|
|
what is an ionic bond? What is an example?
|
bonds including oppositely charged ions(atoms that have lost or gain electrons) are attracted to each other. Table salt NACl

what is covalennt bonding?
|
where atoms share electrons
|
|
|
what are hydrogen bonds?
|
weak bonds that can easily be broken and put back together
|
|
|
hydrogen bonds are formed between what?
|
positively charged hydrogen atoms that are covalently bonded to negatively charged oxygen or nitrogen or etc of another molecule
|
|
|
how are covalent bonds formed?
|
by the sharing of electrons between atoms
