Anatomic Terminology

If the right and left parts of the sagittal plane are unequal, the plane is the referred to as the:
parasagittal plane
Anatomic Terminology

The _____ plane divides the body or organ vertically into a front and rear part
Frotal (Coronal) plane
Anatomic Terminology

The ______ plane divides the body or organ horizontally into a top and bottom part
Horizontal (transverse) plane

The thoracic cavity can be broken down into what smaller cavities?
Plueral cavities for each lung, and the pericardial cavity for the heart.
The abdominopelvic cavity can be broken down into what smaller cavities?

Molecules

Define matter
Anything that takes up space and has mass
Molecules

Matter consists of ____ that posess unique physical and chemical properties.
Elements
Molecules

An atom is defined as
the smallest quantity of an element that still possesses the characteristics of that element.
Molecules

Atoms chemically bond together to form
molecules
Molecules

When the atoms in a molecule are different, the molecule is a ______
compound
Molecules

The three types of bonds are
Ionic
Covalent
Hydrogen
Molecules

Define ionic bonds
Ionic bonds form between two atoms when one or more electrons are completely transferred from one atom to the other. The atom that gains electrons has an overall negative charge, and the atom that donates electrons has an overall positive charge.
Molecules

Why are these atoms called ions?
Because of their positive or negative charges, these atoms are ions.
Molecules

Define covalent bonds
Covalent bonds form when electrons are shared between atoms. That is, neither atom completely retains possession of the electrons (as happens with atoms that form ionic bonds).
Molecules

When two atoms sharing electrons are exactly the same, the electrons are shared equally, and the bond is a _____ covalent bond
Nonpolar
Molecules

Polar colvalent bonds form when
unequal distribution of the electrons creates areas within the molecule that have either a negative or positive charge (H2O)
Molecules

Hydrogen are weak bonds that form between ____ and ____
the positively charged hydrogen atom in one covalently bonded molecule and the negatively charged area of another covalently bonded molecule.
Inorganic Compounds

Define hydrophillic
Warer loving
Inorganic Compounds

Polar covalent substances are water _____
soluble
Inorganic Compounds

Nonpolar covalent substances do not dissolve in water and are called
hydrophobic
Organic Compounds

Large organic compounds are called______
macromolecules
Organic Compounds

Polymers are molecules that consist of a ________
a single unit (monomer) repeated many times.
