2-Nasal necrosis, protein-urea,vasculitis…….Diagnosis???

3-Wegener’s granulomatosis??

4-Epidemic and lest chances of liver cirrhosis ??

*hepatitis E

5-What doesn’t affects preload??

  1. Preloadis affected by venous blood pressure and the rate of venous return.
  1. These are affected by venous tone and volume of circulating blood.
  2. Preload is related to the ventricular end-diastolic volume

 

  1. higher end-diastolic volume implies a higher preload.

pre

Acidosis —–>lactic acid production —–>vasodilation ——>   ↓ preload ↓stroke vol

Acidosis… –> hyperkelimia …–> ↓ force of contraction …. ↓stroke volume

Note:  Decrease in stroke volume is mainly due to decreased contractility of left ventricle

CO= SV x HR

&

STROKE VOLUME –> three factors (CAP)

 

  1. Contractlilty

2.Afterload

  1. 3.Preload

 

SV= EDV-ESV

SV is dependent on EDV (determined by preload)

ESV (determined by contractility).
EDV IS inversely proportional to HR.

CO DEPENDS ON VENOUS RETURN!!!!

Cushing disease:- increased ACTH from pituitary that stimulates adrenal.

Cushing syndrome:- excess steroids due to any cause.
Cushing triad:- headache,vomiting and papiloedema.
Cushing reflex:- increased BP with reflex bradycardia.
Cushing ulcer:- peptic ulcer due to CNS trauma or tumor.

57-Pneumatic bones in face??

Which of the following is not a pneumatic bone?
A. Frontal bone
B. Sphenoid
C. Maxilla
D. Mandible

 

Q.All are pneumatic bones Except ?
A : Maxilla
B : Parietal
C : Ethmoid
D : Mastoid

 

Q.spheniod bone is an example of;
A.irregular bone  (Irregular bones are vertebrae,sacrum & mandible  jaw)
B.pneumatic bone
C.short bones
D.flat bones

 

Pneumatic bones are those which enclose an air filled cavity
They are seen in relation to the nasal cavity (paranasal sinuses) and the middle ear
The pneumatic bones are:
Frontal
Sphenoid
Ethmoid
Maxilla
Temporal (mastoid air cells)

 

58-Caseating granuloma in TB??

59-Effect of anesthesia is fastest on which fiber??

60-Which one is COX-2 inhibitor??miloxi

61-Mu and kappa receptors??

62-What happens in irreversible ischemia of cell??

63-Circular fibers??

64-Hormone released during sleep??

65-Ansa cervicalis?? C123 plus hypoglossal collectively called ansa

ans

Ansa Cervicalis, all are correct except,

  1. Supply to carotid body.
    B. C1, 2, 3.
    C. Joins hypoglossal.
    D. Supply thyrohyoid.

 

 

 

66-Prostacyclin (PGI(2)) causes what??

Which of the following decrease platelet aggregation & cause vasodilatation?

  1. PGE2
  2. PGF2alpha
  3. TBXA2
  4. PGD2
  5. E. PGI2

 

PGI2 (prostacyclin) – most potent inhibitor of platelet aggregation (by increasing platelet cAMP) and causes relaxation of vascular smooth muscle.

 

Note:

 

1.ADH +angiotensin .thromboxin .prostaglandin F are
vasoconstrictors
2.lactate+k+adenosin .prostacyclin .prostaglandin E are vasodilators

 

67-Azygos vein??

relation of right vagus nerve with trachea while entering thorax?
1.direct contact
2.separated by recurrant laryngeal nerve
3.azygos vein
4.separated by phrenic nerve
5.separated by brachiocephalic vein

73-Exercise increases end expiratory volume??

74-Most ventilated apex of the lung??

 

 

Insulin facilitates glucose uptake in all of the following tissues except?

 

1-Cardiac muscle

2-Leukocytes answer

3-Brain

4-Adipose tissue

5-Mammary gland

NOTE!!

 

Tissues in which insulin facilitates glucose uptake:-

 

  • Skeletal muscle
  • Cardiac muscle
  • Smooth muscle
  • Adipose tissue
  • Leukocytes
  • Crystalline lens of the eye
  • Pituitary
  • Fibroblasts
  • Mammary gland
  • Aorta
  • A cells of pancreatic islets

 

Tissues in which insulin does not facilitate glucose uptake:-

 

  • Brain (except probably part of hypothalamus)
  • Kidney tubules
  • Intestinal mucosa
  • Red blood cells

 

 

Atropine is used clinically to treat?

 

1-Tachycardia

2-Bradycardia

 

“A goes with B”: So Atropine is used clinically to treat Bradycardia.

 

 

 

NOTE:

Atropine generally is contraindicated in patients with(except in doses ordinarily used for preanesthetic medication)

1- Glaucoma

2- Pyloric stenosis

3- Prostatic hypertrophy
