Exam 12: The Central Nervous System

The area of the cortex that is responsible for sensations of the full bladder and the feeling that your lungs will burst when you hold your breath too long is the ________.

A patient was admitted to the medical/surgical unit with a stroke that affected the motor neurons in the pyramidal pathway. This affected the loss of voluntary movement to his left side. What other problems would the patient experience?

Two terms for the massive motor tracts serving voluntary movement are ________.

Explain why heparin is used as an anticoagulant in the treatment of thrombotic strokes but contraindicated in a subarachnoid hemorrhage.

One functional center found within the medulla oblongata is a respiratory center involved in the control of the rate and depth of breathing.

Figure 12.3 Using Figure 12.3, match the following: -Site containing central canal.

Figure 12.1 Using Fig. 12.1, Match the following: -White fiber tracts

Match the following: A) Primary motor cortex B) Prefrontal area C) Thalamus D) Hypothalamus -A major relay station for sensory information ascending to primary sensory areas of the cerebral cortex. Contains many specialized nuclei.

NREM sleep normally exhibits four distinct stages, which appear to alternate.

Important nuclei of the indirect (multineural) system that receive impulses from the equilibrium apparatus of the inner ear and help to maintain balance by varying muscle tone of postural muscles are the ________.

The first obvious sign that the nervous system is forming in the embryo is the thickening of the surface ectoderm to form the neural plate.

A disturbance of posture, muscle tremors at rest, and uncontrolled muscle contraction are all symptoms of damage to the basal nuclei.

Figure 12.1 Using Fig. 12.1, Match the following: -Medulla Oblongata

Match the following: A) Cerebrum B) Cerebellum C) Hypothalamus D) Thalamus E) Brain stem -Gateway to the cerebrum

Match the following: A) Occipital lobe B) Temporal lobe C) Parietal lobe D) Frontal lobe E) Insula -Auditory area.

What is the cauda equina and why is it given this name?

The ________ is a conduction pathway between higher and lower brain centers and houses nuclei for cranial nerves V-VII.

Match the following: A) Occipital lobe B) Temporal lobe C) Parietal lobe D) Frontal lobe E) Insula -Motor speech area.
