Cards

Term
gross anatomy
Definition
regional, systemic, surface, clinical, developmental, and surgical anatomy
Term
microscopic anatomy
Definition
cytology and histology
Term
3 essential concepts
Definition
complementary nature of structure & function, structural organization, homeostasis
Term
feedback loops
Definition
control center, receptors that monitor changes, effectors receive information from the control center and produce a response
Term
negative feedback
Definition
reverses changes
Term
positive feedback
Definition
brings a process to completion
Term
2 main divisions of the body
Definition
axial and appendicular
Term
visceral
Definition
guts
Term
visceral membrane
Definition
membrane closest to the organs
Term
parietal membrane
Definition
membrane that lines the body walls
Term
pleural membrane
Definition
lines the lungs
Term
pericardial membrane
Definition
surrounds the heart
Term
peritoneum
Definition
surrounds the abdominal organs
Term
superior
Definition
cephalic or cranial
Term
inferior
Definition
caudal
Term
anterior
Definition
ventral
Term
posterior
Definition
dorsal
Term
medial/mesial
Definition
toward the midline
Term
lateral
Definition
toward the side of the body or away from the midline
Term
intermediate
Definition
between 2 structures
Term
ipsilateral
Definition
on the same side of the body
Term
contralateral
Definition
on opposite sides of the body
Term
superficial
Definition
toward the surface of the body
Term
deep
Definition
away from the body surface
Term
carbohydrates
Definition
supply energy and build some cell structures

sugars, starches, glycogen, cellulose

can have same formula (glucose and fructose) but differ in shape (isomers)

3-7 carbons

chains can be straight or highly branched
Term
polysaccharide
Definition
formed by dehydration synthesis

don't dissolve in water & not "sweet"
Term
monosaccharides/disaccharides
Definition
dissolve in water and are more rapidly distributed
Term
lipids
Definition
contain C,H,O

C:H nearly 1:2

usually hydrophobic/insoluble in water

fats, oils, waxes

fatty acids, triglycerides, phopholipids, glycolipids, steroids, and eicosanoids

concentrated chemical energy

good storage form; protect and insulate

make up cell membranes
Term
fatty acids
Definition
one end has a carboxyl group (COOH)

hydrocarbon tail (longer the tail lower the solubility)

fatty acids bind to glycerol to form neutral fats or triglycerides
Term
eicosanoids
Definition
prostaglandins (local hormones & leukotrines)
Term
protein function
Definition
support, movement, transport, buffering, metabolic regulation, coordiantion and control, defense
Term
proteins
Definition
contain C, H, O, and N (sometimes S & P)

acts as an anion
Term
amino acids
Definition
made of amine group, carboxyl group, R group, and a central carbon
Term
nucleic acids
Definition
made up of C, H, O, N, and P
