With increase cardiac output, arterioles begin to stretch, and mechanically-gated ion channels in smooth muscle surrounding the arterioles open. This causes the smooth muscle cells to depolarize and fire action potentials so that these smooth muscle cells contract and the arterioles stop stretching. This is called: Group of answer choices myogenic autoregulation. the Frank-Starling law of the heart. excitation-contraction coupling. active hyperemia.

Step 1
The process involves increased cardiac output leading to the stretching of arterioles, which then triggers mechanically-gated ion channels in the smooth muscle cells surrounding the arterioles to open. Show more…

In the disease tetanus, muscles undergo periods of spasm, in which they maximally contract and are unable to relax. During such a spasm, the muscles are in a state of sustained contraction. A scientist has produced a type of myosin that can bind ATP but has lost its hydrolyzing capability. What will be the state of a muscle that includes this myosin within its sarcomeres? You have been hit with a shrink-ray and have entered a muscle fiber to explore the action of a muscle at a microscopic scale. You move close to a myosin head and have to dodge a bit of inorganic phosphate that goes flying by. Which stage of the muscle contraction has this myosin filament just completed? What would be the outcome if you prevented the removal of calcium ions from the sarcoplasm into the sarcoplasmic reticulum? What describes the contraction of a muscle at the level of protein interactions? A muscle that is denied ATP will be unable to contract. A mad scientist is attempting to produce a paralytic agent to administer to their superspy nemesis. They have worked with a number of possibilities and have settled on interfering with proteins critical for muscle contraction. Recommend to the scientist a suitable means of achieving this goal. A new kind of vertebrate has been discovered with muscle fibers that lack t tubules. Predict a compensatory change in the microanatomy of the muscle fiber in comparison to the standard vertebrate condition. A muscle fiber has been exposed to anatoxin, an acetylcholine mimic that irreversibly binds to ACh-gated channels in cell membranes. What will happen to this muscle? How is a muscle contraction similar to the transmission of a stimulus to the central nervous system? A patient reports to a clinic with symptoms of muscle weakness and sluggish contraction. A test of nerve function revealed no neural disease, and there is no indication of any mitochondrial disease. What is a possible explanation for this patient's symptoms?

3. Botulinum toxin and tetanus toxin are closely related neurotoxins; therefore, they act the same way and cause the same type of paralysis. 4. Blood cells that play an important protective role in helping us kill & destroy worms (helminthes) are microfold cells. 5. The class of antibody in an antibody response to an antigen is always the same each time the body responds to the same antigen. 6. Our textbook considers these normal microbiota to be part of the innate immune response because their presence might be able to prevent pathogens from colonizing the host at certain body sites by competing with the pathogens for nutrients or receptor sites, by producing substances such as bacteriocins that are harmful to the pathogens, or by altering conditions that could affect the growth of the pathogens. 7. The ability of a phagocytic cell to migrate from a blood vessel to an area where there is tissue damage involves the phagocytic cell squeezing in between endothelial cells lining the blood vessel. This process is known as peregrination. Multiple Choice - Exam 4 only 8. Responses of the innate immune response are activated by protein receptors in the plasma membrane of defensive cells such as macrophages. These activators include molecules referred to as ______ which attach to various commonly found components on pathogens called pathogen-associated molecular patterns (PAMPs) which include molecules like lipopolysaccharide. a) Toll-like receptors b) major histocompatibility complex receptors c) Fc receptors d) prostaglandin receptor 9. Histamine, produced in an allergy response and during inflammatory responses, causes an increase in the permeability of capillary walls as well as ______ of blood vessels. Therefore, when a person has an overwhelming allergy response they will suffer from ______ blood pressure. a) constriction ; low b) dilation ; low c) constriction ; high d) dilation ; high 10. T helper 1 cells release the cytokine ______ which results in macrophage activation so that the macrophages are better able to take care of intracellular pathogens like the tuberculosis bacterium. a) gamma interferon b) apoptopin c) properdin d) serotonin 11. Some microorganisms can increase the amount of the sugar sialic acid on their surface such as by attaching it to their lipopolysaccharide or lipooligosaccharide. This interferes with the functioning of ______. a) antibody-dependent cell mediated cytotoxicity b) the complement cascade c) agglutination d) margination
