Definitions (ch 1, 2) Flashcards
Analgesia
The relief from the absence of pain. Not generally used on fish, but sometimes individually.
Sedation
a state of lowered awareness or anxiety, without loss of equilibria. Often for handling/transportation. Reduces stress. Does not cause analgesia
Anesthesia
loss of sensation in the body, can either be local or systemic. General is most common with fish.
Safety Margin
difference between concentration required for anaesthesia vs. lethal concentration.
Erythrocyte
the red blood cells (‘rbcs’). nucleated. primary roll to aid respiration via oxygen and co2. most common
Leucocyte
the white blood cells (‘wbcs’). key cells of the immune system. many specialized types. larger than red, often irregularily shaped.
Phagocyte
an enlarged leucocyte designed to engulf foreign particles. may originate from mature neutrophils or mature monocytes
Neutrophil
a type of leucocyte, primarily involved in the short term , rapid, non-specific immune response.
Lymphocyte
one type of leucocyte that is involved int he ‘memory component’ of the long term specific immune response. They produce antibodies
Thrombocyte
responsible for blood clotting, via release of an enzyme thromboplastin that acts on fibrinogen to clog a site of injury.
Induction Time:
time to reach specific stage of anaesthesia
Recovery time
time to regain full consciousness
