Medulla oblongata

Anatomy review for the nervous system - Week 12 Study Guide 1. Distinguish the difference between neuron, neuroglial cells, Schwann cells, neurofibrils, and astrocytes. Neuron: masses of nerve cells in nervous tissue Neuroglial Cells: provide neurons physiological requirements (fill spaces, give support to neurons) Schwann Cells: larger axons of peripheral neurons enclosed in sheaths Neurofibrils: thin, long fibrils that run through body of neuron and extends to axon and dendrites; gives…

can interfere with the normal process of respiration. Breathing occurs subconsciously without one being aware of its different steps: stimulation of the respiratory control centers in your brain, inhalation, gas exchange, and exhalation. The medulla oblongata controls the body when to breathe. During the ventilation, process the phrenic nerve sends a signal to the primary breathing muscle, the diaphragm then contracts and flattens downward giving more space in the thoracic cavity. By…

Introduction of Patient My patient is Freda Wilson, a 64-year-old Caucasian female who resides in Shawnee, Kansas with her husband. Mrs. Wilson is 5’5” tall and weighs 148 pounds, has two adult children, and is a relatively healthy individual. Mrs. Wilson and her husband spent five days in Oklahoma babysitting their grandchildren, two boys – one and three years old. Within 24 hours of returning home, Mrs. Wilson had a headache, felt fatigue, and later in the afternoon spiked a fever in excess…

taste sensations: sour, sweet, bitter, salty, and umami. Only one of the five tastes is detected by a single taste receptor cell. The sensory impulses from these cells travel on fibers of the glossopharyngeal, facial, and vagus nerves to the medulla oblongata. 3. Sense of Hearing The ear is associated with the sense of hearing. The inner ear, also known as the labyrinth, has two parts called the osseous and the membranous labyrinths. The cochlea is a part of the labyrinths that functions in…

1. The different types of respiration are cellular, internal, and external. In external respiration there is an exchange between air and blood in the lungs and internal has exchange between the blood and body tissues. Cellular respiration is a chemical reaction inside the mitochondria of cells in and cellular metabolism is converting energy in food to become ATP. 2. The olfactory mucosa is the lines of the roof in the nasal cavity. The respiratory mucosa is lining the rest of the nasal cavity…

The nervous system is broken down into two major systems: Central Nervous System and Peripheral Nervous System. We’ll discuss the Central Nervous System first. The Central Nervous System consists of the brain and the spinal cord. The Cerebral Cortex, which is involved in a variety of higher cognitive, emotional, sensory, and motor functions is more developed in humans than any other animal. It is what we see when we picture a human brain, the gray matter with a multitude of folds covering the…

Burning Question: What are all the parts of the brain and what are their functions ‘Brainy’ Facts The brain. You couldn’t live without it. It helps you move, breathe, eat sleep, et cetera. It is the most complex organ and controls all of your body’s functions. When I was in kindergarten, I had an accident and fractured my skull, had a minor brain bleed and a small concussion In first grade, I had surgery to fix up my brain and skull. All of these injuries took a major toll on my brain. The…

brain has many different parts, one of which is the forebrain, which has the function of comprehending sensory information, which is very important. The hindbrain is also very important. It can be divided into three parts, which consist of the medulla oblongata, pons and cerebellum (Human Brain). The cerebellum plays a role in processing sensory information that has been carried from the forebrain through the…

State one of three descending control of pain system. (1pts) 1) The prefrontal cerebral cortex projects to the central gray region of the mesencephalon 2) The central gray projects to the raphe magnus and the nuc. Reticularis gigantocellularis in the medulla 3) The medullary nuclei make inhibitory contact in lamina I,II, and V in the dorsal horn of the…

In addition, KMC ensures cardiorespiratory stability especially in the case of interhospital ambulance transport. According to the Transport Risk Index of Physiologic Stability (TRIPS) scale, the main predictors of an illness severity include temperature, BP and respiratory status of the infant (Sontheimer et al, 1995). Kangaroo mother care, however, has the ability to address these predictors effectively; consequently, this ability makes KMC a better transport compared to transport in an…
