additional midterm 1 cards Flashcards
dorsal vs ventral streams
dorsal: above, where, unconscious
ventral: below, what pathway, conscious
postmitotic
neurons cannot be replaced after injruy, they are postmitotic
intramolecular
within, within atoms
intermolecular
between molecules gives water its surface tension
What is intracellular and extracellular fluid?
aqeous solution, water is the solvent
macromolecules
nucleic acids, proteins, carbohydrates
nucleic acids: dna and rna transmission, expression of genes
Proteins: almost every cellular function
Carbs: cellular fuel
Conformation
givesd protein its 3d shape through folding
what do the hydrophobic tails of the phospholipid bilayer do?
stops polar molecules from entering the cell
parts of the endomembrane system
er, golgi, vesicles, lysosomes
medial geniculate nucleus and lateral geniculate nucleus location and function
medial: auditory
lateral: visual
three names for the forebrain
forebrain, cerebrum, and telencephalon
exclusions to law of bell and magendie
not vision or hearingg
where is the superior colliculus and inferior colliculus located
in tectum/roof, posterior
Darwin and Alfred Russel Wallace:
both contributed to the theory of evolution
Russel published his work a year before Darwin
Darwin published Origin of Species, provided biological mechanism for every single function you can think of
methlyation
DNA methylation is a biological process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription.
Eukaryotes:
have a nucleus
Archea:
prokaryotes, extremophiles, live in earth’s most extreme environments
protists
A protist or protoctist is any eukaryotic organism that is not an animal, land plant, or fungus
Pitekia rash:
burst blood vessels looks like purple dots
ans reflexes vs somatic nervous system reflexes
coughing, sneezing, vomiting, and swallowin
sns: Reflex arcs that impact the organs are called autonomic reflex arcs while those that affect the muscles are referred to as somatic reflex arcs.
Globus pallidus primary function
The primary function of the globus pallidus is to control conscious and proprioceptive movements.
Bacteria
Bacteria are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. NO NUCLEUS
What does the law of Bell aMnd Magendie not apply to?
vision or hearing
