Comprehensive assignment Essay

1. (5 pts) Describe the metabolic lick providing your cypher speckle you were walking (at an easy pace) before the bee stung you. Include which molecules argon existence consumed.The metabolic assist providing my energy while I was walking at an easy pace is aerobic metabolism. During aerobic metabolism, mitochondria absorb from the surrounding cytol these molecules ADP, phosphate ions, O2, and organic substances like pyruvate. These molecules go through the citric dosage cycle. The electron transport chain is also involved to create adenosine triphosphate. For each(prenominal) molecule of pyruvate that goes into the citric acid cycle, the cell gains 17 ATP molecules. glycogen reserves potentiometer also be used and converted to glucose. Glycolysis breaks worst glucose molecules to create to a great extent pyruvate. However, if not enough glycogen is available, the cell force out also use amino acids and lipids to do this. This is a very efficient process but also only contributes a fr process of the ATP during aerobic metabolism. At moderate levels of activity, most of the energy during aerobic metabolism comes from work done by the mitochondria. The muscles involved during this process need altogether of the energy produced as ATP, and there is no extra left everyplace in this particular metabolic process if muscle activity increases ( vigor wind P. 306-7).2. (8 pts) Trace the sound of the bee from your outer ear to knowledge. (Include all nidusing, conduction, transduction, transmission and perception processes and structures).Sound vibrations from the buzzing bee vibrate the air molecules as insisting waves around my ear and enter the auricle which is cone-shaped in ready to direct these sound waves into the ear via the external acoustic meatus. The sound waves appreciation the tympanic tissue layer through the external acoustic meatus and cause it to vibrate. When the tympanic membrane moves, it causes the auditory ossicles to move . The auditory ossicles be do up of the malleus, incus, and stapes. These ossicles ar important because they amplify the sound. The stapes then transfers this movement to the oval windowpane and the force waves move through the perilymph of the scala vestibuli. These waves then disturb the basilar membrane as they move toward the round windowof the scala tympani. This causes vibrations of hair cells against the tectorial membrane. The education more or less where the sound originated and roughly how strong the pressure waves ar is interpreted by the central sick system over the cochlear branch of cranial poise VIII (The Special Senses P. 584-5).3.

(8 pts) Trace the image of the bee to perception. (Include all focusing, transduction, transmission and perception processes and structures). later on a retinal molecule absorbs light, the normally 11-cis form of the bound retinal molecule straightens to become the 11-trans from. This change activated the opsin molecule. Opsin activates transducin which is a G protein. This G protein then activates phosphodiesterase. Phosphodiesterase is an enzyme that breaks down cyclic-GMP. The break-down of cyclic-GMP removes them from the gated atomic number 11 channels and makes the gated sodium channels inactive. Because of this, sodium ion en campaign into the cytoplasm decreases. This sodium ion reduction then reduces the dark current. busy transport continues to remove sodium ions from the cytoplasm even though the gated sodium channels atomic number 18 closed. This causes the transmembrane potential to drop down to -70 mV and hyperpolarize. This hyperpolarization decreases neurotran smitter release. The adjacent cell is then aw ar that the photoreceptor has absorbed a photon. A particular proposition ganglion cell keeps track of a limited portion of the visual field. Rods argon also called M cells and give the brain information about a general location of received photons and light rather than very specific information.Cones are also called P cells and can be much more specific than rods. The P cells are smaller and more numerous than M cells. This helps them be better at giving information about edges, beautiful detail and color. The activation of a P cell gives information about a very specific location. The P cells give high answer information. Axons from the ganglion cells converge on the optic disc, penetrate the eye, and continue toward the diencephalon on the optic nerve.II. From there the information is split in half and travels to the cover version of the brain and to the occipital lobe. Together, the diencephalon and the brain stem process the in formation and pick up eye reflexes and pupil dilation and/or constriction in order to see clearer and focus in on an object. Depth perception is a phenomenon that takes place when the visual cortex of my occipital lobes reviews the slightly distinct information obtained by each eyeball. The superior colliculi of the midbrain make motor commands that control unconscious eye, head, and/or neck exercises that respond to visual stimuli. My eyes in the bright summer light looking at a bee that is so close (on my right shoulder) are likely to constrict so as to limit the photon stimulation on my retina and so as to focus on just the tiny bee (The Special Senses P. 569-74).6. (11 pts) Move your left overstep to swat the bee. (Create a table that describes which muscles move which bones across which joints under the control of which nerves).

(2 pts) What molecule provided the energy for the movement of your arm?ATP (adenosine triphosphate) p rovided the energy for the movement of my arm.8. Feel the pain of the stinger in your shinny.a. (3 pts) What layers of the skin are penetrated and what tissue types make them up?The epidermis is the outermost layer of skin, and it is made of stratified squamous epithelium. The dermis is deep to the epidermis and it is made of dense insurgent connective tissue. The hypodermis is deep to the dermis and is made of adipose tissue (The Tissue Level of Organization P. 114-126).b. (5 pts) Trace the pain sensation from the receptors to perception.There are pain receptors on the shoulder that communicate to the central nervous system. Because a bee sting is a stinging, injection-like pain, it would be considered firm pain. Fast pain sensations are carried by myelinated Type A fibers. The myelination helps the information to travel double-quick down the neuron. The bee sting stimulates the dendrites ofnociceptors in the shoulder and causes depolarization. The initial segment of the axon m ust reach threshold in order to release an action potential. Once an action potential is released, it travels by neurons to the central nervous system. When the action potential reaches the central nervous system, glutamate and/or substance P are released as neurotransmitters. These neurotransmitters make it easier for neurons to travel along pain pathways. This is known as pain perception (Neural desegregation I Sensory Pathways and the physical loathsome System P. 498).9. (8 pts) Explain your autonomic response to this event. State which percentage is taking control and describe exactly how that division will nitty-gritty respire rate, heart rate, and pupil size. (Note dont just describe the effect, but describe the control pathway that leads to that effect, including any chemical messengers involved.)The openhearted division of the autonomic nervous system is taking control. This division increases external respiration rate, heart rate, and pupil size. The nonrational m otor nuclei in the hypothalamus activates autonomic nuclei in the brain stem and spinal stack. The brain stem and spinal cord in turn activate autonomic ganglia that then stimulate visceral effectors such as smooth muscle, glands, cardiac muscle, and adipocytes. Smooth muscle effectors collide with rakehell vessels by constricting them and increasing blood pressure and bucket along up blood flow in order to increase group O circulation. The smooth muscle also affects the constriction/dilation of the lungs. The gentle nervous system wants to dilate the lungs to increase breathing rates and oxygen intake. The glands that are stimulated cause the body to perspire. The cardiac muscle increases heart rate. Adipocytes can be used for energy because they are fatty acids (lipids) and can be used to make ATP during glycolysis very quickly (Neural Integration II The autonomic flyaway System and Higher-Order Functions P. 518-523).10. (6 pts) Describe the elements of the homeostatic contr ol system that caused the sweating and the red skin. Include the control pathway involved.The control pathway of the sympathetic division that caused the sweating andthe red skin was the sympathetic chain ganglia. Preganglionic fibers carried motor commands that affect the head, neck, limbs, and thoracic cavity. The unmyelinated postganglionic fibers that control the body wall enter the gray ramus and return to the spinal nerve for further distribution. They then are able to innervate the sweat glands of the skin and the smooth muscles in blood vessels. This innervation causes the sweat glands to sweat and the blood vessels to constrict. Constricting the blood vessels is helpful because it will raise blood pressure and increase oxygen circulation (Neural Integration II The Autonomic Nervous System and Higher-Order Functions P. 521)11. (1 pts) Describe the metabolic process providing your energy while you were campaign (as fast as you could) after the bee stung you. Include which mo lecule(s) is(are) being consumed.The metabolic process that was providing my energy while I was running as fast as I could was anaerobic metabolism. This metabolic process does not supplicate oxygen and uses glycolysis to turn over 2 ATP molecules but also to generate 2 pyruvate molecules. Each pyruvate molecule can be broken down by the mitochondria to generate 17 ATP molecules. This is a total of 34 ATP molecules. This is a lot of energy and is necessary when muscles are at peak activity levels (Muscle Tissue P. 306-7).12. (5 pts) Explain what the Epi-Pen contains (what kind of chemical is that) and how that will help in this situation. What effect will that pen fuddle on the breathing rate?The Epi-Pen contains epinephrine which is a neurotransmitter. It will try to improve the situation of an allergic reaction by increasing breathing rate, increasing heart rate, raise dropping blood pressure, reduce inflammation, and get up hives (Drugs and Medications Epipen im).Works Cited Drugs and Medications Epipen im.
