Biology BTutorial Seven- Nervous and Endocrine System4. Create a concept map to outline the relationship between the hypothalamus, the anterior andposterior pituitary, and their target organs. You should include the 9 hormones produced in thehypothalamus, 7 produced in the anterior pituitary gland and 2 secreted from the posteriorpituitary gland. Note the stimuli for each secretion, the target tissue's response, and anyfeedback regulation.AnteriorpituitaryHypothalamusPosteriorpituitary3 Biology BTutorial Seven- Nervous and Endocrine SystemCompare this summary to the tables provided in the lecture. Which format works better for yourrevision and understanding? During your own revision, expand on your preferred format toinclude all the endocrine organs and their hormones.5. Hormonal secretions by the endocrine system occur due to detection of a stimulus whichsignals a deviation from homeostasis. As an example of a humoral stimulus, outline bloodglucose regulation. You can use a figure or describe the stimulus, sensor, effector andresponse.

A cell secretes a product that diffuses through the interstitial fluid and acts on nearby cells. This process is an example of (a) neuroendocrine secretion (b) autocrine signaling (c) paracrine signaling (d) classical endocrine regulation (e) peptide hormone function
The hormone insulin enhances the carrier-mediated transport of glucose into most of the bodys cells but not into brain cells. The uptake of glucose from the blood by neurons does not depend on insulin. Knowing the brains need for a continuous supply of blood-borne glucose, predict the effect that insulin excess would have on the brain.
Watch this video (http://openstaxcollege.org/l/summation) to learn about summation. The process of converting electrical signals to chemical signals and back requires subtle changes that can result in transient increases or decreases in membrane voltage. To cause a lasting change in the target cell, multiple signals are usually added together, or summated. Does spatial summation have to happen all at once, or can the separate signals arrive on the postsynaptic neuron at slightly different times? Explain your answer.
Identify the classical vertebrate endocrine glands and describe the actions of their hormones; describe the effects of hypersecretion and hyposecretion on homeostasis.
Watch this video (http://openstaxcollege.org/l/nervsystem1) to learn more about the nervous system. As described in this video, the nervous system has a way to deal with threats and stress that is separate from the conscious control of the somatic nervous system. The system comes from a time when threats were about survival, but in the modern age, these responses become part of stress and anxiety. This video describes how the autonomic system is only part of the response to threats, or stressors. What other organ system gets involved, and what part of the brain coordinates the two systems for the entire response, including epinephrine (adrenaline) and cortisol?
Watch this video (http://openstaxcollege.org/l/3Dmovies) to learn about the side effects of 3-D movies. As discussed in this video, movies that are shot in 3-D can cause motion sickness, which elicits the autonomic symptoms of nausea and sweating. The disconnection between the perceived motion on the screen and the lack of any change in equilibrium stimulates these symptoms. Why do you think sitting close to the screen or right in the middle of the theater makes motion sickness during a 3-D movie worse?
Visit this site (http://openstaxcollege.org/l/neurolab) to see a virtual neurophysiology lab, and to observe electrophysiological processes in the nervous system, where scientists directly measure the electrical signals produced by neurons. Often, the action potentials occur so rapidly that watching a screen to see them occur is not helpful. A speaker is powered by the signals recorded from a neuron and it pops each time the neuron fires an action potential. These action potentials are firing so fast that it sounds like static on the radio. Electrophysiologists can recognize the patterns within that static to understand what is happening. Why is the leech model used for measuring the electrical activity of neurons instead of using humans?
Which non-nervous tissue develops from the neuroectoderm? respiratory mucosa vertebral bone digestive lining craniofacial bone
A new antagonist molecule has been discovered that binds to and blocks plasma membrane receptors. What effect will this antagonist have on testosterone, a steroid hormone? It will block testosterone from binding to its receptor It will block testosterone from activating cAMP signaling It will increase testosterone-mediated signaling It will not affect testosterone-mediated signaling.
In the propagation of a nerve impulse: a. the refractory period begins as the K+ channel opens, allowing K+ ions to flow outward along their concentrationgradient. b. Na+ ions flow out of the axon with their concentration gradient. c. positive charges lower the membrane potential to its lowestaction potential. d. gated K+ channels open at the same time as the activationgate of Na+ channels closes. e. the depolarizing stimulus lowers the membrane potential toopen the Na+ gates.
