Medulla oblongata Essays

effectiveness in learning. Understanding them and how they work may help your learning ability. 1. THE MEDULLA OBLONGATA. Medulla Oblongata is otherwise known as PRIMITIVE BRAIN or BRAIN STEM. This part of the brain controls the involuntary actions in one's body system such as heartbeat, sleep, breathing etc.  FUNCTIONS OF MEDULLA OBLONGATA: *Medulla Oblongata is a part of brain that react to stress and danger* *It is a part of the brain that gets your muscles

Medulla oblongata - I would keep this part of the brain because the brainstem controls and regulates heart rate, breathing, and swallowing. These are necessary functions in order to survive. If you damaged or removed the medulla oblongata, it could result in death. Cerebrum - I would keep this part of the brain because it controls our voluntary movement, such as writing and running. It also helps your body stay balanced and in the upright position. If you did not have the cerebrum, your body would

Many psychologists, professors and other researchers have studied the mechanism and explanation of having a left-handed trait among a few individuals. The brain hemisphere division of labor is the most accepted theory about the left-handedness of a person. (Broca, 1960) proposed that the handedness of a person can be associated by the brain hemisphere division of labor. The brain is divided into two hemispheres which are the right and left hemisphere. Each of the hemispheres has their different functions

The use of certain colors associated with clothing in a film can help tell a story, show a character's journey or who they are to the story, and it helps communicate ideas to the audience. In a film such as King Arthur: Legend of the Sword, the battle between good and evil is represented by light colors like white, tan, or light brown and black in clothing, but when using magic, the characters who represent “good” have blue, gold, and silver accents while “evil” characters have red, orange, and black

In the Bible, Jesus said to disciples “Go into all the world and proclaim the gospel to the whole creation.” However, nowadays, Christians starts to cloister themselves and wants to stay in their comfort zone, just like the “royalties” at the party in “The Masque of the Red Death”. The people in the story have a party inside an abbey and locked themselves in there while the disease that devours people runs like a hungry lion outside the abbey. In the end, the pestilence comes into the abbey also

The brainstem is located underneath the limbic system is the brain stem. The midbrain includes the tectum and tegmentum. The brain stem is made up of the midbrain, pons, and medulla. The midbrain is the rostral part of the brain stem. The pons are a part of the metencephalon in the hindbrain. The medulla oblongata is located between the pons and spinal cord. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. The midbrain is involved in functions

Hind brain (Rhombincephalan) the hind brain contain the brain stem and the medulla oblongata (Myelencephalon) form by the anterior thickening of basal plate and posterior alar plate separated by sulcus in the fourth ventricle. The hind brain continues to form the spinal cord. As like cerebrum, cerebellum has fissured mass in the posterior cranial fossa attached with brain stem by three pairs of peduncles. From the base of the brain stem the 12 pairs of cranial nerves are arising. The motor nuclei

the midbrain to the medulla and cerebrum. It plays as an important role in controlling the rate and length of respiration. The medulla oblongata is an extension of the spinal cord as it lies just inside the cranial cavity above the large hole in the occipital bone called the foramen magnum. Within it, contained a number of reflex centers for control of blood vessel diameter, heart rate, breathing, coughing, swallowing, vomiting and sneezing. On either side of the medulla oblongata is a round oval protrusion

pressure baroreceptor is the receptors and the medulla oblongata is the control centre while cardiovascular system is the effectors in the regulation blood pressure. When heart rate increase in a human body, more blood will pump into the arteries and will result in increasing in the blood pressure. This event detects by baroreceptors in the arteries wall and receptors will send impulses to the control centre known as medulla oblongata. Medulla oblongata will interpret the message and send the message

causes the rest of the body to become fatigue due to the lack of oxygen the organs are receiving. When low level of oxygen is picked up by the chemoreceptors (special cells that notes the level of oxygen and carbon dioxide) and it signals the medulla oblongata which controls the breathing rate and the heart rate.

The hindbrain is responsible for our autonomic functions such as heart rate, blood pressure and breathing, it is mainly controlled by the nuclei in the hindbrain, particularly in an area called the medulla oblongata ( Bernstein, 2016, pg.59). There are three part in the hindbrain known as the medulla, the reticular and the cerebellum. The hindbrain controls all the things that you want to automatically work without having to think about them. Can you imagine having to remind your heart to beat or

the thorax by transmitting nerve impulses from centers in the brain which signals either contraction or relaxation (absence of nerve impulses). The respiratory center can be divided into two sections: the medullary respiratory center in the medulla oblongata and the pontine respiratory group (or pneumotaxic area) in the pons. The medullary respiratory

When the both sympathetic and parasympathetic ganglion direct to the same organ or gland the total function of the gland is carried by the input signals given by chain ganglia and the terminal ganglia. E.g. the sympathetic ganglion can increase the heart rate and the parasympathetic ganglion can decrease the heart rate. Terminal ganglia in the sympathetic nervous system receive impulses from the head, neck, thoracic and lumber regions. Terminal ganglia of the parasympathetic system receive impulses

Paw Preference in Dogs Did you know that dogs have a paw preference similar to left or right handedness of humans? People do not think of dogs using one paw more than the other paw, in other words being left or right pawed. Many dogs do have a particular paw they prefer unlike some dogs that use both paws, and do not have a paw preference. Which paw does your dog prefer? The dog’s skeletal system is the framework of the dog’s body (Wells 1). The bones of the skeletal system serve as levers to the

Carl Koller can be accredited with the first medical use of Cocaine. Koller was in search of a drug that he could use during ophthalmic surgeries. He had tried many other agents before cocaine, which included chloral, bromide and morphine. These were unsuccessful because they lead to retching, vomiting, and restlessness. Sigma Freud who was a colleague of Koller, was trying to break a morphine habit of a young physiologist by using cocaine. Sigma Freud then asked Koller to assist him in experiments

Sigmund Freud, being a philosopher, significantly created an impact in the practice of medicine. He started his expert profession as a neurologist and clinical specialist. While his commitments to psychoanalytic hypothesis represent his overall expertise, it is his initial work in the neurosciences that Freud trusted would present to him the expert admiration of the world he wanted. At present, his contributions to neurology, neuropathology, and anesthesia are overlooked by other people. In truth

brain stem has three parts to it, but only the pons and medulla oblongata play a key role in breathing. The medulla helps set the respiratory rhythm by receiving and sending impulses to a bundle of neurons called the ventral respiratory group to the phrenic nerve to bring about contraction in the diaphragm and external intercostal muscles. All this only happens though due to the sensors of the chemoreceptors. The chemoreceptors located in the medulla and carotid and aortic bodies detect a rise in carbon

Introduction Cranial nerves are part of the peripheral nervous system, PNS. They relay motor and sensory data to the oral musculature and muscles of the pharynx and larynx. This information is pivotal for operating proper speech and swallowing mechanisms. Therefore, it is important that the speech-language pathologist be familiar with the name, distribution, and anatomy of all of the cranial nerves. It is also necessary to know the testing procedures involved with cranial nerves as well as signs

Leigh Syndrome: Case Series of Three Patients Purpose Leigh syndrome is a rare progressive neurodegenerative disorder with a poor prognosis. Typical imaging findings are one of the diagnostic criteria and may prompt the clinician to investigate for Leigh syndrome. To describe those characteristic magnetic resonance imaging (MRI) findings as well as clinical presentation, we present 3 cases of pediatric patients who met diagnostic criteria for Leigh syndrome at our institute in the last 5 years

and thoughts. Yep, brains are absolutely like remote controls! It has 3 anatomical divisions: Forebrain that contains the cerebrum, thalamus and hypothalamus, Midbrain, which is a part of the brainstem and Hindbrain that contains the pons, medulla oblongata and cerebellum. Cerebrum, cerebellum and the brainstem are considered as the three main parts of the human brain. Cerebrum is the largest part which makes up 85% of the brain’s
