Question
Chapter 40, Problem 3Q
Summary Introduction
To review:
The tissue and organ changes that take place during the fight-or-flight response in mammals, and how these changes are different from those in the iris.
Introduction:
In mammals, the fight-or-flight response is controlled by the release of the hormone epinephrine from the medulla of the adrenal gland. These responses occur in response to a potential threat or danger and involve the sympathetic nervous system (SNS), a part of the autonomic nervous system (ANS).

SGMP PDE membrane Excitation Answer the following questions with regards to this figure and the signal cascade triggered by adrenaline through the B-adrenergic receptor. The light receptor rhodopsin (Rh) has an analogous structure to the B-adrenergic receptor therefore this receptor should be a GPCR. O A. B. a ligand-gated ion channel. Oca B-barrel protein.

O E. a globular protein.arrow_forwardIn the disease myasthenia gravis, the human body makes—by mistake— antibodies to its own acetylcholine receptor molecules. These antibodies bind to and inactivate acetylcholine receptors on the plasma membrane of muscle cells. The disease leads to a devastating progressive weakening of the people affected. early on, they may have difficulty opening their eyelids, for example, and, in an animal model of the disease, rabbits have difficulty holding their ears up. As the disease progresses, most muscles weaken, and people with myasthenia gravis have difficulty speaking and swallowing. eventually, impaired breathing can cause death. explain which step of muscle function is affected.arrow_forward
- Chemoreception in vertebrates and insects is mediated through clearly distinguishable senses of taste and smell. Contrast these two senses in humans in terms of anatomical location and nature of the receptors and sensitivity to chemical molecules.

Iris Cells capillary endothelial cells Lens cells rods bipolar cells horizontal cells ganglion cellsarrow_forwardThe rattlesnake alerts enemies to its presence with a rattle—aset of modified scales at the tip of its tail. Describe the distinctroles of gated ion channels in initiating and moving a signalalong the nerve from the snake’s head to its tail and then fromthat nerve to the muscle that shakes the rattlearrow_forward
- Among vertebrates, acoustico-lateralis hair cells are used todetect water currents in lateral line organs of fish, gravity andacceleration in the labyrinth, and sound in the cochlea. How cansimilar receptor cells mediate all these responses?arrow_forwardIn most neurons, membrane depolarization leads to the opening of voltage-dependent ion channels, generation of an action potential, and, ultimately, an influx of Ca2+, which causes release of neurotransmitter at the axon terminus. Devise a cellular strategy by which hyperpolarization in rod cells could produce excitation of the visual pathway and passage of visual signals to the brain. (Hint: The neuronal signaling pathway in higher organisms consists of a series of neurons that relay information to the brain. The signal released by one neuron can be either excitatory or inhibitory to the following, postsynaptic neuron.)arrow_forwardPhotoreceptors in the retina have special channels that are open to Na+ in the dark. When light hits photoreceptors, these special channels close. What can you cònclude from this? None of the above O Photoreceptors hyperpolarize to light Photoreceptors depolarize to light Photoreceptor voltage does not change in the presence of lightarrow_forward
- Select the options that properly describe the function and features of rods. A bright blue light would stimulate rods more than cones. In low light conditions rods perceive color as gray cale. sensitive to bright light conditions. Rods are sensitive to vision in low light conditions. In low light conditions rods perceive color as blue scale. Low light conditions are viewed in blue scale. O The absorbance of rhodopsin in the rods is much more sensitive than in the cone opsins. Rods are sensitive to vision in bright light conditions. sensitive to low light conditions. Rods are sensitive to low light conditions. V The absorbance of rhodopsin in the cones is much more sensitive than in the rods opsins. Rods are sensitive to bright light conditions.arrow_forwardWhen the neurotransmitter acetylcholine (ACh) binds the acetylcholine receptor (a GPCR) on muscle cells, it causes them to contract. ZIGGY, a chemical analog of ACh, also binds to the same acetylcholine receptor on muscle cells, but instead causes the muscle cells to relax. For this reason, it is sometimes prescribed as a muscle relaxer. Explain in 3-4 sentences how ZIGGY could cause muscle relaxation. How can both ZIGGY and ACh bind the same GPCR? And then how can they have different effects on the cells, despite binding to the same receptor on the same cells?arrow_forwardHected to several cnidocytes through neural connections, help regulate groups of cnidocytes. Using the description above, deduce the different types of sensory cells that operate cnidocyte discharge including the mechanisms that induce an action potential. 2. Calmodulin is found in smooth muscle cells and performs a similar function to troponin in striated muscle fibers. However, calmodulin not only gets activated by Ca2+ but also slows the release of Ca2+ from the sarcoplasmic reticulum. How might this difference relate to the different kinds of contractions smooth muscles do in comparison to striated muscles? 3. A study of muscle fibers between chimpanzees and humans revealed that although muscle mass per body size are approximately equivalent, the ratio of red (slow) and white (fast) fibers were significantly different. Chimps tend to have a ratio of 30% red to 70% white where humans are 60/40 respectively. Speculate about what this ratio difference means in terms of muscle activity…arrow_forward
