Introduction:
The spinal cord is a collection of nerve tissue that arises from the brain stem. It is a site that contains many motor neurons, interneurons, and complex neural circuits. It is often called as ‘nuts and bolts’ of the nervous system. It controls and enables the forces on muscles and its adaptive movements. The nervous tissue of the spinal cord is composed of organized cells that involve the body movements and send the signals to different parts of the body. The spinal cord tracts are stimulatory nerve pathways that pass the information through action potentials. The spinal tracts are important to diagnose and manage the spinal cord damages or injuries.

- Julio D., who had recently retired, was enjoying an afternoon of playing golf when suddenly he experienced a severe headache and dizziness. These symptoms were quickly followed by numbness and partial paralysis on the tipper right side of his body, accompanied by an inability to speak. After being rushed to the emergency room, Julio was diagnosed as having suffered a stroke. Given the observed neurological impairment, what areas of his brain were affected?arrow_forwardThe limbic system is composed of several interconnected structures including the olfactory bulbs, amygdala, hypothalamus, hippocampus, parahippocampal gyrus, cingulate gyrus, subcallosal gyrus, septal nuclei, mammillary bodies, and the thalamus. Pair each of these structures with their function listed below: -This limbic area is active when you are trying to memorize the names of brain areas. It is also severely atrophied in people suffering from late stages of Alzheimer’s Disease. -This limbic area is active when you are watching something that makes you feel sad. -This limbic area is active when you feel thirsty. -When the activity of this limbic area is increased you feel a sense of pleasure. -When this limbic area is damaged it often results in patients experiencing anterograde amnesia. -Damage to this limbic structure while rare often results in patients going into a coma. -This cortical limbic structure plays a large role in motivation and movement and has recently been…arrow_forwardHydrocephalous is medical condition that results from the imbalance in the rate of production and absortion of cerebrospinal fluid in central nervous system. Describe the Production, flow and absorption of Cerebrospinal Fluid in the central nervous system.arrow_forward
- Explain how the cerebrumof the brain is connected both functionally and structurally to other parts of the brain. Give a thorough explanation of the function of this structure of the brain. There is a story about a man that had a metal rod go through his face (and brain) and yet survived. Explain how someone could have such a traumatic brain injury, but still survive. In addition, explain what would happen if a similar accident (trauma) were to happen to the cerebrum. This not a part of a homework assignmentarrow_forwardDescribe expected functional losses in a patient who has suffered injury to the right occipital lobe of the cerebral cortex compared to injury in the right temporal lobe of the cerebral cortex.arrow_forwardExplain how The Cerebrum part of the brain is connected both functionally and structurally to other parts of the brain. Give a thorough explanation of the function of this structure of the brain. There is a story about a man that had a metal rod go through his face (and brain) and yet survived. Explain how someone could have such a traumatic brain injury, but still survive. In addition, explain what would happen if a similar accident (trauma) were to happen to the cerebrumarrow_forward
- Damage to specific regions of the cerebral cortex, such as through a stroke, can result in specific losses of function. What functions would likely be lost by a stroke in the temporal lobe?arrow_forwardWhat motor deficits are expected in a cerebral palsy patient? Specify pattern of motor problems in each kind of cerebral palsy. thank you.arrow_forwardIn planning treatment for a patient who has had a cerebrovascular accident (CVA), why would it be important to know whether the CVA was caused by a ruptured or obstructed blood vessel? HINT Why would the treatments for the two types of CVAs be different?arrow_forward
- Describe the production, flow and absorption of Cerebrospinal Fluid in the central nervous system.arrow_forwardYou are walking to class, pondering the intricacies of physiology, when you trip over an uneven place in the sidewalk and fall. Unhurt but embarrassed and angry, you jump up and glance around to see if anyone is watching. From your knowledge of neuroanatomy and function, explain how the following areas of the brain might be involved in this scenario: cerebrum cerebellum limbic systemarrow_forwardExplain the descending pathway from the brain where Mr. Dexter decides to move his right leg to the actual movement of his quadriceps. (Use complete sentences.) Use key words in this order: primary motor cortex in precentral gyrus, frontal lobe, descending tract, decussate, ventral horn with motor neuron in lumbar spinal cord, ventral root, spinal nerve, sciatic nerve in lumbosacral plexus, muscles to move leg (ie. quadriceps)to take a step.arrow_forward
