Document Summary
Two systems coordinate communication throughout the body: the endocrine system and the nervous system. The endocrine system secretes hormones that coordinate slower but longer acting responses. Including reproduction, development, energy metabolism, growth, and behavior. The nervous system conveys high-speed electrical signals along specialized cells called neurons; These signals regulate other cells are mostly short-acting. Concept 45. 2: feedback regulation and coordination with the nervous system are common in endocrine signaling. 45. 10) the negative feedback loop in simple endocrine pathway inhibits a response by reducing initial stimulus, preventing excessive pathway activity. (neutralizes acidity) In a simple neuroendocrine pathway, the stimulus is received by a sensory neuron, which then stimulates a neurosecretory target cell (fig. Positive feedback reinforces a stimulus to produce an even greater response. For example, in mammals oxytocin causes the release of milk, causing greater suckling by offspring, which stimulates the release of more: coordination of neuroendocrine and endocrine signaling i.
