Critical thinking questions about the nervous system

Visit this site to read about a woman that notices that her daughter is having trouble walking up the stairs. Each of the three fluid filled canals is on a different plane. Stimuli that are received by sensory structures are communicated to the nervous system where that information is processed.

The CNS then creates a motor plan that is executed by the efferent branch working with effector organs.

Human Physiology/Appendix 1: answers to review questions

A photograph of a face is projected on the screen away from the center. What are the two different types of epilepsy? This leads to the specific response that will be generated.

To what functional division of the nervous system would these structures belong? The nervous system can cause the contraction of all three types of muscle tissue. Maybe you have seen an advertisement on a website saying that there is a secret to unlocking the full potential of your mind—as if there were 90 percent of your brain sitting idle, just waiting for you to use it.

Functional Divisions of the Nervous System In addition to the anatomical divisions listed above, the nervous system can also be divided on the basis of its functions. What two parts make up this system? Nervous tissue can also be described as gray matter and white matter on the basis of its appearance in unstained tissue.

That is not homeostatic, it is the physiological response to an emotional state. There is one important process that every neuron has called an axon, which is the fiber that connects a neuron with its target.

A single axon can be part of a nerve and a tract. Review Questions[ edit ] 1. What is hip dysphasia? That is not homeostatic, it is the physiological response to an emotional state.

This is a tool to see the structures of the body not just the nervous system that depends on magnetic fields associated with certain atomic nuclei. It is the center of an atom, where protons and neutrons are found; it is the center of a cell, where the DNA is found; and it is a center of some function in the CNS.

Seeing a baseball pitched to a batter will not automatically cause the batter to swing. The retina does the following; A allows vision in light and dark, using cones and rods B Gives depth perception using binocular vision C Contains the ciliary muscles that control the shape of the lens D Protects and supports the shape of the eye 3.

The anatomical divisions are the central and peripheral nervous systems. What do the three semicircular canals in the inner ear enable us to do? The same axons extend from the eye to the brain through these two bundles of fibers, but the chiasm represents the border between peripheral and central.

More receptors, such as AMPA receptors, are added and existing ones are sensitized via phosphorylation. There are no rods in the fovea, so little light is picked up when you stare directly at the object. Vision[ edit ] 1. The stimuli for taste and smell are both chemical substances molecules, compounds, ions, etc.

Review Questions Critical Thinking Questions 1. In the PNS, a cluster of neuron cell bodies is referred to as a ganglion. There are some differences between the two, but for our purposes here there will be a good bit of overlap. An example of this kind of measurement is functional magnetic resonance imaging fMRIwhich generates a map of the most active areas and can be generated and presented in three dimensions [link].

There are some differences between the two, but for our purposes here there will be a good bit of overlap. Also, the results from an MRI session are compared with images obtained from X-ray or computed tomography. Some somatic motor responses are reflexes, and often happen without a conscious decision to perform them.


You have an ear infection. Sensory input for autonomic functions can be from sensory structures tuned to external or internal environmental stimuli.Anatomy and Physiology Chapter 20 Central Nervous System Critical Thinking Questions What term refers to the membranous cove What are the large fluid-filled spaces.

Critical thinking is a higher order of thinking: it is the practice of using a number of different advanced thinking skills in a variety of complex ways. The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses).

The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions). But there is a third function that needs to be included.
