Ventilatory action of the hypaxial muscles of the lizard Iguana iguana: a function of slow muscle.
Patterns of muscle activity during lung ventilation, patterns of innervation and some contractile properties were measured in the hypaxial muscles of green iguanas. Electromyography shows that only four hypaxial muscles are involved in breathing. Expiration is produced by two deep hypaxial muscles, the transversalis and the retrahentes costarum. Inspiration is produced by the external and inter...
متن کاملCirculatory impairment induced by exercise in the lizard Iguana iguana.
Mechanical integration of the cardiac, muscular and ventilatory pumps enables mammals to vary cardiac output over a wide range to match metabolic demands. We have found this integration lacking in a lizard (Iguana iguana) that differs from mammals because blood flow from the caudal body and ventilation are maximal after, rather than during, exercise. Because Iguana iguana are constrained from v...
متن کاملIguana virus, a herpes-like virus isolated from cultured cells of a lizard, Iguana iguana.
An agent cytopathic for Terrapene and Iguana cell cultures was isolated from spontaneously degenerating cell cultures prepared from a green iguana (Iguana iguana). The agent, designated iguana virus, caused a cytopathic effect (CPE) of a giant cell type, with eosinophilic inclusions commonly observed within giant cell nuclei. Incubation temperature had a marked effect on CPE and on virus releas...
متن کاملNitrogen excretion during embryonic development of the green iguana, Iguana iguana (Reptilia; Squamata).
Development within the cleidoic egg of birds and reptiles presents the embryo with the problem of accumulation of wastes from nitrogen metabolism. Ammonia derived from protein catabolism is converted into the less toxic product urea or relatively insoluble uric acid. The pattern of nitrogen excretion of the green iguana, Iguana iguana, was determined during embryonic development using samples f...
متن کاملAlfaxalone anaesthesia in the green iguana (Iguana iguana).
OBJECTIVE To characterise the anaesthetic effects of alfaxalone administered intramuscularly (IM) at 10, 20, and 30 mg kg(-1) . STUDY DESIGN Prospective, randomized cross-over study. ANIMALS Ten juvenile green iguanas (Iguana iguana) of mean body weight (±SD) 480 ± 134 g. METHODS Alfaxalone was administered IM in the triceps of both thoracic limbs. Times for anaesthetic induction, plateau...
