Document Summary
Describe how the study of ectotherms has contributed to our understanding of fever: a lizard (an ectotherm), when infected with a certain bacteria, seeks a warmer environment and maintains an elevated body temperature. Fish do similar things, as well as amphibians and cockroaches, which indicate that raising body temperature in response to infection is a common feature. Signaling by hormones endocrine cell signal goes everywhere in bloodstream to cells anywhere that have the receptor for the signal. ); ductless; secreted into blood stream; ex: pancreas (insulin, ant pit: nervous - signals transmitted by neurons cell body of other neurons. Nerve impulse takes them down an axon to a specific location (cells connected by junctions to an axon that transmits an impulse); more specific. Pancreas has exocrine (bicarbonate, amylase, nucleases into small intestine) and endocrine (insulin, glucagon) functions: describe the components of a simple endocrine pathway the molecules that produce the response i. ex: epinephrine.
