What ratio of body weight is Body Water

60%

100
What is the CNS comprised of

Brain and Spine

100

What are the two types of Synapses

Electrical and Chemical (predominantly chemical)

100

What are the two divisions of the ANS? What is their place of origin from the CNS

Parasympathetic nervous system (Cranio-sacral), and Sympathetic Nervous System (thoraco-lumbar)

100

What are the five senses? (scientific names)

Auditory, Somatic, Gustatory, visual, olfaction

200

What amount of BW is ICF?

40%

200

What type of Neurons lead away from the CNS

Motor or Efferent Neurons

200
Neurotransmitter that is predominantly used and covered in lecture

Acetylcholine.

200
If you give an animal Atropine what part of the ANS does it act on and how?
Parasympathetic nervous system. Blocks the receptors on the target tissue. 
200

Are Pacinian corpuscle phasic or tonic with adaptation? 

Phasic. quick adaptation to deep pressure stimuli. Remember they are laminated like onions and will be round when being stimulated

300

What ion has a higher concentration in the cell? Na or K

K

300
How does the body react to something hot or very cold when the impulse is too slow for normal neurons

Interneurons

300

Does the Neuron make new NT every time for a new AP?

No they are repackaged after binding to the post synaptic site and reused.

300

Which ANS neurons are expected to be of near equal length.

Sympathetic

300

Why do our sense have separate regions of the brain to control them?

Senses have to be independently taken and then processed together to map the surroundings. This is why some animals Have "multiple"/ divided brains for body fucntions.

400
What causes water to flow to areas of Higher Osmotic Pressure

Presence of solutes and particles

400

Action potentials are characterized by not degrading, having the ability to travel long distances, a threshold for potential to fire, and _____. What is the missing characteristic

All or none- A signal will either cause depolarization or it won't

400

Enzyme in the synaptic gap used to remove leftover ACH

Acetylcholinesterase. Think about what happens if this is inhibited.

400

if you give a Pt a ANS antagonist,st what would you expect to occur

Blocked response to both parasympathetic and sympathetic nervous systems. What is a situation you can think of wanting to do this? Atropine for organophosphate poisoning. 

400

An animal olfactory bulb is what dictates how good its olfactory sense will be. Which will have better smell a German shepherd or a Domestic shorthair cat. 

German shepherd. Kind of tricky since animals also have different olfactory profiles based on diet.
500
A pt is given fluids that are at 200 mOs when they are dehydrated. Was this the proper treatment

No, Isotonic is preferred with hypertonic being used in rare critical cases. Hypotonic risks swelling the cells to quickly leading to cell death.

500

With repolarization there is a period in which stimuli can act to restimulate the tissue. What is this period and what is an example of a tissue that does not allow this

Refractory period. Heart has an absolute refractory period. (no stimuli can cause a new AP)

500

After an AP has occured a inhibitory enzyme is activated what is the impact of this?

The neuron cascade has only sent one message and will lead to the inability of feedback reaction

500

If an animal is presenting emesis and lacrimation what do these symptoms show as and what is the rememdy

Symptoms of Organophosphate poisoning. Administer Atropine
