.Middle cerebral artery The middle cerebral artery supplies blood to the lateral portion of the cerebral hemisphere. This is an area where most of the primary motor cortex and primary somatosensory cortex is located. As a result, the loss of blood flow though this artery would cause major sensory and motor deficits. However, there may be some sparing of motor usage and sensation in the lower extremity because most of this area of the primary motor cortex and primary somatosensory cortex is supplied by the anterior cerebral artery.

Parkinson's disease is the most likely diagnosis for this patient. Parkinson's disease is a cumulative nervous system disorder that influences movement. The symptoms of the disease start gradually, and sometimes it may start with barely a noticeable tremor in just one hand. Tremors are common with this illness. The disorder is also notorious for causing stiffness or slowing of movement. Parkinson’s disease symptoms include muscle rigidity, tremors, and also changes in speech and gait. It can also affect balance and coordination. Tics and uncontrollable movement are also common.

Schizophrenia is a mental illness where patients start to hear voices in their heads. They can develop split personalities and often believe that someone is telling them to do something. Such patients often repeat senseless words and phrases. Sometimes they can experience euphoria when such an episode is about to start. The biggest problem is that they do not trust anyone. They often think that doctors are bad and about to get you. Often they also think that they are powerful and can do anything, which leads to severe consequences. However, they do not exhibit flattened emotional expression. This last feature is associated with Parkinsonism.

1hour e cylinder will last @ 10 flow

What is the formula to solve for flow using O2 set and flow set?

Levodopa/carbidopa

.Sodium and potassium will flow through the same channel A single cation channel opens allowing sodium ions to flow into the cell and potassium ions to flow out simultaneously. Since the flow of sodium is much greater, more positive charges will enter the cell and it will become depolarized.

Phineas Gage Phineas Gage was the famous brain damage patient who had the accident on the Burlington and Rutland railroad.

Posterior cerebral artery Internal carotid artery Anterior communicating artery Anterior cerebral artery Posterior communicating arteryRemember, the medial cerebral artery is technically not considered part of the Circle of Willis even though it branches off directly from the internal carotid artery.

Parkinson s disease

Gyri; sulci The smooth raised surfaces of the cerebral cortex are called gyri and the indentations or fissures are called sulci.

Glutamate; GABA Glutamate and GABA are the most common excitatory and inhibitory neurotransmitters in the brain respectively. They are both amino acid neurotransmitters.
