A & P test over quiz 1 and new info Flashcards
medial plane
cuts the body into equal left and right regions
frontal plane
cuts body into equal front and back regions
transverse plane
cuts body into equal top and bottom parts
abdominal cavity
RUQ, LUQ, RLQ, LLQ —> R hypochondriac region, epigastric region, L hypo, R lumbar region, umbilical region, L lumbar, R iliac, hypogastric region, L iliac
muscular tissue
movement of skeleton, beating of heart, movement of food through digestive system
connective tissue
makes up bone, cartilage, blood, connects organs together
nervous tissue
conducts electrical impulses through the brain, spinal cord, and nerves
epithelial tissue
makes up skin, lining of internal pathways, and glands
nucleus
control center, contains genetic info
endoplasmic reticulum
synthesizes proteins and ships them around the cell (smooth or rough ER)
mitochondria
converts food into ATP (cellular respiration)
Golgi apparatus
packages and transports materials around the cell in sacs called vessicles
lysosomes
break down waste using hydrolytic enzymes
centrioles
aid in cell division
vacuoles
store nutrients and water, plants have larger vacuoles than animals
DNA info
found in nucleus (46 chromosomes made of DNA in every body cell).
shaped in a double helix.
sides of ladder are sugars and phosphates
rungs are made of nitrogen bases (A,T,G,C) -base pairing
transcription
DNA–> RNA (happens in nucleus)
translation
RNA–>proteins (happens in the cytoplasm)
polypeptide
link of amino acids
mitosis
division of body cells
one parent–> two identical daughter cells
Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
meiosis
division of sex cells
one parent–> four diff daughter cells
same as mitosis x2
semi-permeable barrier
only some substances can pass through
passive transport (diffusion and osmosis)
molecules move naturally from high to low concentrations (no energy required)
active transport
move molecules from low to high concentrations (energy required through ATP)
-endocytosis
-exocytosis
