Claude Bernard Determined the concept of homeostasis, but not the actual word
Who named homeostasis? Walter Cannon
Which type of response involves integration system Reflux
Where is interstitial fluid found Extracellular Fluid
T/F Electrical Signals occur everywhere False, they only occur in nerve and muscle cells
Where are chemical signals secreted ECF-specifically interstitial fluid
Via endocrine communication, where would the chemical hormone go first Intracellular
Fluid,
then the blood and interstitial fluid,
finally the target cell if the receptor is present
T/F the length of the axon determines the distance the electrical signal released by an neuron
can travel True, the longer axon the further the chemical signal can travel
Which type of cell to cell communication releases an electrical signal down an axon, and then is
secreted into the blood Neuro Endocrine
What is an word for being able to cross the plasma membrane? Lipophobic because the it is
unable to pass through the lipid bilayer
,T/F would an antagonist ligand activate its respected receptor False Antagonist ligand act as
an blocker, with agonist would activitate its respected receptor
Why does cholera occur an enzyme blocks the g-protein and the cAMP production.
Specifically this enzyme interferes with the alpha unit inhibiting the conversion of GTP to GDP
What are the two types of controls for Cannon's Postulates Tonic Controls-1 set of
parameters
Antagonistic Controls-2 set of parameters, parasympathetic and sympathetic
If an indivudal has an heart attack, what would cannons postulates suggest? The
antagonistic control failed and the sympathetic system, increased the heart rate too much,
while if someone drops dead the parasympathetic system decreased the heart rate
significantly.
What does Cannons Postulates suggest The nervous system has a key role in maintaining the
fitness of internal environment, through coordinating blood movement, pressure and
osmolality and body temp.
Define cephalization the concentration of sense organs, nervous control, etc., at the anterior
end of the body, forming a head and brain, both during evolution and in the course of an
embryo's development.
What forms the Diencephalon and Cerebrum The forebrain
The hindbrain turns into what part of the brain Medulla Oblongata, Cerebellum and Pons
What is the outer part of the cerebrum Cerebrum Cortex
Diencephalon and midbrain are found where Under the cerebrum
, What components make up the brainstem Mid-Brain
Cerebellum
Pons
What is the meninges 3 layers of protection surrounding the brain and spinal cord
What are the 3 layers of the meninges Dura (furthest outside)
Arachnoid
Pia
T/F an subdural hematoma occurs under the dura layer of the brain True
Where can cerebral spinal fluid be found? Lateral Ventricles,
Third Ventricle,
Fourth Ventricle, which runs into the central canal
An Dr. is analyzing one's cerebral spinal fluid and finds high levels of protein, and bacterian
what would that indicate An disease or condition, there should be nothing in the CSF
What roll does ependymal cells play in terms of CSF They regulate and control production of
CSF, while the production itself is done by the choroid plexus
How does CSF exit the the brain 1 main exit under the 4th ventricle
- Arachnoid villi takes the CSF to
- the arachnoid tissue
- CSF pass through arachnoid tissue to the dural or venus sinus
