Arachnoid mater

concussion is. A concussion is an injury that you cannot see which is why some people calls it an invisible injury because you can get hit in the head very hard and not have any bruises or cuts on your head but you would still have a concussion because you would later feel the symptoms coming. The brain is surrounded by a fluid and protective membranes that separates the skull from the brain and it is called the meninge. The purpose of the meninges is to Protecting the brain and spinal cord from mechanical injury, Providing blood supply to the skull and to the hemispheres, Providing a space for the flow of cerebrospinal fluid (interactive biology). The meninges is a protective tissue but it also has 3 layers. It has the dura mater, the pia mater, and the arachnoid mater, the meninges is what protects the brain from hitting your skull, if you would not have a meninges the littlest bumps you would get to the head you would get a concussion. After you are cleared from a concussion you can still feel some of the symptoms for 4-6 more weeks. Adults and children both have similar symptoms when they get a concussion but they will both treat it differently. In an adult some symptoms that they could get would be headaches, they would feel weaker than they usually are, vomiting and nausea, slurred speech, acting differently than you usually act,easily agitated, etc. In children the symptoms are similar but they would act differently than an adult like for example a child with a…

Cars 3 is an animated sports film directed by Brain Fee. In the movie, Lightning McQueen (the main character), found himself fighting to stay relevant in the vast and ever-changing world of Cars. As new cars and superior models entered onto the race track, Lighting started to fall behind the batch. Thus, he tired reinvented himself to compete at a high level.

leadership are demonstrated by Mr Hill in the change process at Mater Health Services (Mr Hill, 2016). Charismatic leadership is utilised in situation that generally related to social change and renewal (Levay, 2010). The charismatic leaders change their followers’ minds and attitudes according to the leaders’ ideas by using persuasion communication (Levay, 2010). According to Grabo & Vugt (2016), the key components of charismatic leadership are the abilities to obtain consent among all…

the symptoms, I would claim that the patient has Spinal Meningitis. Meningitis is a rare infection of the arachnoid and pia mater membranes that cover the spinal cord (Meningitis). This infection can be bacterial or viral transmitted by direct spread and can progress within a few hours or days. Common symptoms include: severe headaches, high fever, stiff neck, fatigue, muscle aches, skin rash, and photophobia (Drake 434). The patient has five of these seven symptoms. The likely cause of her…

the neurons for the 12 pairs of thoracic spinal nerves. The lumbar part contains the neurons for the 5 pairs of lumbar spinal nerves. The sacral part contains neurons for the 5 pairs of sacral spinal nerves. The coccygeal part is the most inferior tip of the spinal cord. It contains one pair of coccygeal spinal nerves. The spinal cord is protected and compressed by spinal cord meninges which are continuous with the cranial meninges. The pia mater is a delicate innermost meningeal layer that…

auditory data, past experiences, and Wernicke’s speech area are controlled and located in the temporal lobe. Wernicke’s speech area deals with language comprehension. Interpretation of spatial information is done by the parietal lobe, which also contains the sensory cortex. The occipital lobe processes what the person sees. The thalamus is the relay center for the cerebral cortex. Regulation of the ANS and the endocrine system is done by the hypothalamus. The limbic system deals with emotion.…

What does the term neroglia mean? What are the 4 types of neuroglia cells in the CNS? Discuss this in detail. Neuroglia is a group of cells, in the nervous tissue that supports neurons that keeps the nervous system functioning and together. The 4 types of neuroglis cells of the CNS: (1.) Astrocytes are cells that support and structure cells that is a barrier for the brain through blood. (2.) Microglial cells are cells that remove dirt and attack microbes. (3.) Ependymal cells are cells that…

membrane's permeability to sodium affect the perception of pain? How to they affect nerve impulses? When are these types of drugs typically used? It prevents impulses from passing through the affected regions, & when it reaches the brain, it doesn't inform it of sensations of touch and pain usually used during surgeries 21. How does caffeine stimulate the activity of the nervous system? Stimulant; increases alertness, reduces fine motor coordination 22. How do amphetamines stimulate the…

(see Fig.6) (Pearce, 2006). 1.2.2 Meninges The spinal cord is protected by three connective tissue layers, termed meninges (see Fig.7). The dura mater is the outermost of these layers and is separated from the bones of the vertebral column by an extradural space. As the roots of the spinal nerves pass laterally through the intervertebral foramina, they are covered by a sleeve of the dura mater that becomes the outer covering of the nerve (epineurium). The arachnoid mater is the next tissue…

Diagram the ventricular system. Be certain to include: the lateral ventricles, the 3rd and 4th ventricles, the cerebral aqueduct, and the central canal. Describe the purpose of the ventricular system. In your answer be certain to define components of this system that are more difficult the diagram; specifically Cerebral Spinal Fluid and Arachnoid granulations. (10 points) The ventricular system is made up of ventricles in the brain which contain CSF (Cerebrospinal fluid). The purpose of the…
