ERTH 2104 Lecture Notes - Lecture 16: Haversian Canal, Ornithopod, Ectotherm
Document Summary
An animal whose metabolism slows to a low level of activity when resting. Body temperature regulation: endothermic organisms regulate their body temperature internally and maintain a nearly constant temperature no matter what the conditions are like outside the body. Poikilotherms: organisms that vary in internal body temperature. Homeotherms : organisms that have a constant internal body temperature. Metabolism: endotherms are capable of higher level of activity sustained over longer periods of. An animal whose metabolism remains at a high level. Fine neuromuscular control to maintain upright posture endotherms. Haversian canals and haversian bone is only found in endotherms. Endotherms have insulation such as feathers and fur. Dinosaurs served a diverse range of metabolic rates: Sauropods (and other large dinosaurs) were mass homeotherms.
