10/11

100

These cranial nerves carry the sensory information of taste

CN X, IX, VII

100

This factor affects encoding of stimulus intensity

Frequency of action potential

100

This cranial nerve carries the afferent sensory information in the pathway of consensual pupillary reflex

Consensual pupillary

100

ALL preganglionic neurons secrete what neurotransmitter onto which cholinergic receptor?

Acetylcholine and nicotinic receptors

100

This adrenergic receptor responds equally to epinephrine and norepinephrine

Beta-1 receptors

12

100

Binding of this ion to tropomyosin will open a binding site for actin and myosin heads, coupling excitation to contraction

Calcium

100

Lactic acid buildup, ATP and calcium depletion are both factors leading to...

Peripheral fatigue

100

This is a specialized region of the muscle cell membrane made of infoldings and ACh receptors

Motor end plate

100

This muscle fiber type has a smaller diameter, more mitochondria, and a darker red color

Slow twitch

100

This molecule is necessary for muscle relaxation

ATP

13

100

This reflex is somatic, cranial, polysynaptic, innate (hint: CN II, III)

Consensual pupillary

100

This reflex is somatic, spinal, monosynaptic, innate (lab)

Knee jerk

14

100

Wiggers Diagram: Pressure in the left ventricle exceeds that of the aorta, opening this valve at which point?

Aortic valve and point A

100

The action potential for this cell features a "plateau phase" in between depolarization and repolarization

Cardiac contractile cell

100

This part of the EKG represents ventricular depolarizaton

QRS

100

This mechanism triggers calcium release from the sarcoplasmic reticulum after calcium enters the cell in contractile cells

Calcium-Induced-Calcium release

100

These cells in the heart are responsible for setting the heart rate

Pacemaker cells

15/16

100

These three factors influence resistance in the cardiovascular system

Diameter, Viscosity, Length

100

Binding of Norepinephrine to alpha-1 receptors will result in this

Vasoconstriction

100

Aortic recoil contributes to this aspect of blood pressure

Diastolic BP

100

In the baroreceptor feedback loop, increased Norepinephrine release and decreased ACh binding to muscarinic receptors leads to this

Increased blood pressure

100

This positive feedback loop mechanism involves activation of proteins to create a fibrin mesh

Coagulation pathway
