Q

What happens in the heart during mid-late ventricular diastole?

A

The ventricles are passively filling with blood.
Atrial pressure> ventricular pressure.
Arterial pressure > ventricular pressure.
The tricuspid and mitral valves are open.
The pulmonary and aortic valves are closed
This represents the P wave on EKG

Q

What happens during Isovolumetric contraction?

A

The ventricles are no longer filling with blood.
Ventricular pressure> atrial pressure.
Arterial pressure> Ventricular pressure.
The tricuspid and mitral valve close, “lub”.
The aortic and pulmonary valves are closed.
This represents QRS wave on EKG.

Q

What happens during mid-late ventricular systole?

A

The ventricles contract and blood is flowing to the aorta and pulmonary arteries
Ventricular pressure> atrial pressure
Ventricular pressure> arterial pressure.
The tricuspid and mitral valves are closed.
The pulmonary and aortic valves are open.
This represents the QRS wave on EKG.

Q

What happens during isovolumtric relaxation?

A

No blood is entering or leaving the ventricles.
Ventricular pressure> atrial pressure
Arterial pressure> ventricular pressure.
Tricuspid valve and mitral valve are closed.
Aortic and pulmonary valve are closed, “dub”.
This represents the T wave on EKG.

Q

If a patient was experiencing atrial fibrillation, what would you expect the P wave to show?

A

The P wave would no longer be visible because the SA node is not functioning properly.

Q

What is ventricular ejection?

A

This is when enough pressure in the ventricles build up more pressure than the aortic and pulmonary pressure.

Q

What is aortic stenosis?

A

Aortic stenosis is when the aortic valve narrows. This puts pressure on the left ventricle causing it to thicken.

Q

What side of the heart is thicker?

A

The left ventricle is thicker because it is responsible for sending blood to the body.

A

Glossopharyngeal: taste sensations to tongue and controlling muscles in the mouth

19
Q

CN X

A

Vagus: larynx, pharynx, thorax, and abdomen

20
Q

CN XI

A

Accessory: shrugging of shoulders

21
Q

CN XII:

A

Hypoglossal: controlling tongue movement

22
Q

A patient is experiencing difficulty moving her face and making facial expressions, this would represent impingement of which nerve?

A

The CN VII facial nerve

23
Q

What are the neurotransmitters and receptors for the parasympathetic nervous system?

A

It starts out with a acetylcholine neurotransmitter and nicotinic receptor at the ganglion. Then it switches to a muscarinic receptor on either the smooth muscle.

24
Q

What are the two divisions of the autonomic nervous system?

A

Parasympathetic (rest and digest), and the sympathetic (fight or flight)

25
Q

What are the neurotransmitters and receptors for the sympathetic nervous system?

A

Starts out with two neurons with ganglion that have acetylcholine neurotransmitters and nicotinic. Then at the end, the neurotransmitters change to epinephrine and norepinephrine with alpha/beta receptors.

26
Q

What is the function of the Pons?

A

The pons is the sight for reticular formation and a relay center for information between the brain and spinal cord.

27
Q

What is the cerebral blood flow anteriorly?

A

common carotid, internal carotid, middle cerebral, anterior cerebral.

28
Q

What is the cerebral blood flow posteriorly?

A

subclavian, vertebral, basilar, posterior cerebral, circle of wills.

29
Q

What dermatome is C4?

A

shoulders

30
Q

What is facilitated diffusion and what are the two types of protein assistance?

A

Facilitated diffusion is the movement of molecules from an area of higher concentration to lower concentration.
Channel mediated- allows water, small polar molecules, and ions to pass through.
Carrier mediated- only allows certain molecules to bind like glucose.

31
Q

How can cancer develop?

A

Changes in cell-cell signaling, dysregulation of the cell cycle, dysregulation of gene expression, and mechanisms of DNA damage like UV, radiation, toxins, and viruses.

31
Q

What is beta oxidation?

A

Beta oxidation is also called fatty acid oxidation and uses fatty acids instead of glucose for energy. The fatty acids are stored in adipose tissue as triglycerides.

32
Q

What are the phases of the cell cycle?

A

G1- growth phase, S- replication phasde, G2- Preparation for mitosis.

33
Q

What are the cyclins and what are they for?

A

Cyclin D: regulates G1 and S phase
Cyclin E: drives cells into the S phase of the cell cycle
Cyclin A: terminates the S phase and leads entering cells into mitosis.
Cyclin B: Triggers mitosis.

34
Q

what part of the brain does executive decision making?

A

Frontal lobe

35
Q

What is PR segment?

A
36
Q

What is ST segment?

A

The plateau of ventricular action potentials

37
Q

What is the T wave?

A

Ventricular repolarization

38
Q

What is the QRS segment?

A

ventricular contraction and depolarization

39
Q

What is the QT interval?

A

Ventricular depolarization to ventricular repolarization

40
Q

What are the arteries that come off of the aorta?

A

Brachiocephalic,

41
Q

What part of the brain does Huntington’s disease affect?

A

Basal Ganglia.

42
Q

What does the ABO blood group represent?

A

Multiple alleles

43
Q

What in influenza allows it to attach to the cell?

A

spikes

44
Q

When the vessel dilates during inflammation, what material diffuses into the vessels?

A

Leukocytes

45
Q

Which one of these is most likely to use facilitated diffuse?

A

K+

46
Q

Which child, daughter or sons, will be a carrier of hemophilia if the dad has hemophilia and the mom does not?

A

Daughters only
