The VII-X thoracic vertebrae were damaged as a result of injury in patient. The hematoma which formed by this injury compresses the dorsal roots of spinal cord. Which pathway will be suffer from the damaging effects?

An organ of nervous system, which consists of grey and white substances, is presented in a histological specimen. Grey substance is located on the periphery. Neurons in the grey matter form three layers molecular, Purkinje and granular. What organ has this structure?

Parenchyma of the organ consists of the nervous tissue in which pseudounipolar neurons are revealed. Perikaryon of the neurons is covered with glial and connective tissue membranes and located in bunches. Name this organ.

As a result of an injury, the integrity of the anterior spinal cord root was broken. Specify the neurons and their processes that had been damaged:

The patient of the neurological department has a loss of sensitivity which associated with disorders of pseudounipolar neurons. Pseudounipolar neurons are a type of bipolar neurons and localized in only one place of the human body. Name it.

An organ of nervous system, which consists of grey and white substances, is represented in a histological specimen. Grey substance is located in the center and consists of efferent neurons, projection neurons and interneurons. Name this organ.

a.

Pons cerebelli

b.

Spinal cord

c.

Cerebellum

d.

Spinal ganglion

e.

Cerebral cortex

In the microspecimen of the spinal cord nucleus neurons of which form motor ending in the skeletal muscles have to be analyzed. Indicate this nucleus

A specimen, dyed by the method of silver impregnation, is being investigated. Pyramidal cells of different size are seen in this specimen. Short processes come off their tips and lateral surfaces; one long process comes off the base of the cells. Name the specimen.

An organ of nervous system which consists of grey and white substances is presented in a histological specimen. Grey substance is located on the periphery and consists of 6 layers: molecular, external granular, external pyramidal, internal granular, internal pyramidal and the layer of polymorphic cells.

An organ of the nervous system which has star-shaped form is presented in a histological specimen. This organ is covered with connective tissue capsule and contains multipolar neurons which have different functions. What organ is this?

Cerebellar cortex is revealed in a specimen impregnated with silver salts. It includes pyriform, basket, stellate and granule cells. Which from mentioned above cells is efferent neuron of cerebellum?

A part of the central nervous system has layerwise allocation of neurocytes, among which there are cells of such forms: stellate, fusiform, horizontal, pyramidal. What

Alcohol intoxication, as a rule, is accompanied by the coordination of movements’ disorder and imbalance caused by the damage of cerebellum structural elements. The function of what cells of cerebellum is affected first of all?

A specimen, dyed by the method of silver impregnation, is being investigated. Pyriform cells with 2-3 climbing up prominent dendrites are seen in this specimen. Name the specimen.

Small cells with short dendrites which have appearance of a “bird’s foot” are visible in the electron microscope picture of the cerebellar cortex in the granular layer. The mossy fibers form synapses in the glomeruli of the cerebellum with dendrites of these cells. What are these cells?

One of sections of central nervous system has layerwise arrangement of neurocytes. There are cells of the following forms: stellate, fusiform, horizontal, pyramidal among them. What section of central nervous system is this structure typical for?

Nerve cells that provide in the human body next function were found during the histological examination of the spinal cord in the anterior horns:

55-year-old patient has disorder of the movements’ coordination and balance as a result of permanent using of alcohol and developing intoxication. What nervous structures of the CNS have been disordered?

As a result of trauma anterior roots of the spinal cord were damaged in a 47-year-old patient. What neurons processes were damaged?

There are two specimens: of the spinal cord and spinal node. Which glial cells can be seen only in specimen of the spinal cord?

Precentral gyrus section of the cerebral cortex is presented in the histological specimen. Indicate which layers mostly developed in this case.

Grey substance was revealed during microscopic investigation of the CNS. Neurons of it form three layers molecular, Purkinje and granular. Name neurons which form second layer?

Large pear-shaped cells were found in the specimen of the CNS impregnated with silver salts. They are arranged in a single row, their top leaves 3-4 processes that ramify in one plane. Name this cells.

A patient with poliomyelitis (which characterized by spinal cord damage) has disorder of skeletal muscles function. What neurons destruction can explain this disorder?

As a result of trauma a patient has damaged anterior roots of the spinal cord. What structures have been affected?

15-year-old patient was admitted to the clinic with diagnosis poliomyelitis. This disease is accompanied with disorder of movements. What nervous structure destruction can explain this disorder?

Cerebellar cortex is revealed in a specimen impregnated with silver salts. It includes pyriform, basket, stellate and granule cells. What neurons constitute molecular layer?
