Question
b. A patient sustained an injury to the lower motor neurons when a board fell on his back at a construction site. The upper motor neurons are intact and undamaged. Determine the effect, if any, on motor control. (2 points) c. Mrs. Sanchez experienced a stroke in her cerebrum and now cannot see with one eye. Her family was told her stroke was situated in the frontal lobe. Did they receive correct information? Explain to support your answer. (3 points) Outline the general pathway for the circulation and reabsorption of cerebrospinal fluid (CSF). Be specific with anatomical locations/terminology to represent your understanding. (2 points) d.Explanation / Answer
Answer-
B:
Patient that sustained an injury to the lower motor neuron because of a board fell on his back at a construction site, the main effect on motor control due to injury on lower motor neuron can cause Muscular atrophy, strength and reflaxes of the affected area is decreased, absence of tendon reflexes in deep areas and flaccid paralysis.
C:
Mrs. Sanchez experienced a stroke in her cerebrum and now can not see with her one eye. her family was told that her stroke was situated in the frontal lobe of the brain.
yes they received correct information bcause cerebrum is that part of brain which occupy front and top area of the brain and it is divided into right and left hemisphere and they controls the opposite side of the body.These hemisphere controls sensation, vision, movement, memory, speech, emotion and thinking. Hence if Mrs. Sanchez can not see with her eye as she experienced a stroke in her frontal lobe (cerebrum) there is chances of visiual problem including an inability to see from the eye.
C:
Outline of general pathway for the circulation and reabsorbtion of CSF as follows-
Lateral ventricles---3rd ventricle(foramen of monro)---adequeduct of sylvius---forth ventrice---foramen of magendie and luschka---subarachnoid space over brain and spinal cord---reabsorption into venous sinus blood via arachnoid granulation
