Question
Chapter 40, Problem 4IQ
a.
Summary Introduction
To explain: The signaling speed and duration of response in the nervous system and endocrine systems.
Introduction: The endocrine system is composed of glands. It secretes and generates hormones. The hormones are chemical substances generated in the body. They regulate the activity of the organs and cells. The internal function of the body is controlled by the nervous system and it interprets, receives, and responds to the stimuli.
b.
Summary Introduction
To explain: How the functions of the endocrine and nervous system differ.

Compare and contrast signaling events in the nervous vs. endocrine systems. How does a “message” get from the original neuron or endocrine gland to the target? How does the signal get transduced into something the target cell can respond to? Be sure to include a description of the signaling molecules and cellular receptors involved in each of these systems.
Signaling within organisms can occur using action potentials (short-term signaling) and/or hormones (long-term
signaling). Identify situations where each type of signaling would be better. Describe why having a long-term signaling
system is beneficial to organisms (2-3 sentences).
The propagation and reception of signals between nerve cells must happen quickly, in order for an organism to respond to stimuli appropriately. Because of that, the majority of neurotransmitters fall into which category?
-Autocrine
-Paracrine
-Endocrine
-Direct signaling

- Which is true about signaling receptors? They are transmembrane proteins that have binding sites for extracellular activated proteinsto effect changes inside the cell. They are transmembrane proteins that have binding sites for extracellular DNA-binding proteins to effect changes inside the cell. They are transmembrane proteins that have binding sites for extracellular enzyme effectors to effect changes inside the cell. They are transmembrane proteins that have binding sites for extracellular messengers to effect changes inside the cell.arrow_forwardWhich of the following statements is true? Question 2 options: a) All cells will respond to the hormonal signal because hormones are broadcast throughout the body. b) The regulation of inflammatory responses at the site of an infection is an example of paracrine signaling. c) Paracrine signaling involves the secretion of stimuli into the bloodstream for distribution throughout the organism. d) The axons of neurons typically signal target cells using membrane-bound signaling molecules that act on receptors in the target cells.arrow_forwardA cell within organ A expresses a protein that is secreted from the cell and travels through the organism’s blood stream to a cell on a distant organ B. The protein binds to a receptor protein on the cell surface of organ B and activates an intracellular signaling pathway resulting in altered gene expression patterns in the cells. What form of intercellular signaling does this represent? Contact-dependent? Paracrine? Synaptic? Endocrine? Autocrine?arrow_forward
- What type of signal transduction is involved in signaling from hormones such as estrogen and testosterone? Explain the signal transduction pathway that occurs. 1. Is there a short term description for signal transduction, instead wrting multiple words to descripte the type of signal transduction? Can I just identify it as active signal transduction and inactive signal transduction. Based on my understanding, active singal transduction is for the fast react transdcution, while inactive signal transduction meanly refers the hormonal affacts on the system. 2. For Ion channels, specific enzymes are both involed activated and inactivated signal transduction?arrow_forwardWhat are the two major mechanisms through which cell signaling leads to a change in cell behavior?arrow_forwardName and explain 5 modes of hormonal/neuroendocrine and neuronal signaling.
