1

Match the pharmacodynamic effects of volatile anesthetics to the site of action.

Study on!!!

2

The essential triad of general anesthetic action includes:

  1. Unconsciousness
  2. Amnesia
  3. Immobility

3

Volatile agents also modulate the ----- function and may provide some analgesia

Autonomic function

4

Volatile anesthetics produce Unconsciousness by altering Higher-order cerebral functions that take place in the -----

Cerebral cortex

5

Volatile anesthetics produce Unconsciousness by altering the functioning of the Relay station of sensory and motor input to the cortex that takes place in the -----

Thalamus

6

Volatile anesthetics produce Unconsciousness by altering the region that influences consciousness and arousal. This region is also known as:

Reticular activating system

7

Volatile anesthetics produce Amnesia by altering Emotion, response to pain, formation of stress response. These originate from the -----.

 

Amygdala

8

Volatile anesthetics produce Amnesia by altering Memory formation, which takes place in the -----.

 

Hippocampus

9

Volatile anesthetics produce Immobility by altering Upper and lower motor neurons synapses in the ----- horn of the spinal cord

 

Ventral horn

10

Volatile anesthetics produce Analgesia by inhibiting the Nociceptive signals along the ascending pain pathway of the ----- tract

 

Spinothalamic tract

11

Volatile anesthetics produce Autonomic modulation by altering the Control center for autonomic reflexes located in the ----- and -----.

Pons and Medulla

12

Match the pharmacodynamic effects of volatile anesthetics to the site of action.

Analgesia + Spinothalamic tract

Immobility + Ventral horn

Amnesia + Hippocampus

Unconsciousness + Reticular activating system
