What would be the functional problems that would be experienced by a person in which the fiber tracts listed below have been cut. As part of your description give an example of an everyday event or activity and how it would be affected if the given tract was cut. Type your answers by number in the response box. 1. Dorsal column-medial lemniscal pathways 2. Anterolateral pathways 3. Spinocerebellar tracts 4. Pyramidal tracts

The Functional problems to be experienced when each fiber tracts is cut ;

1) Inability of to feel pain and temperature stimulus  

2) Inability to perceive touch and pressure by the person

3) Inability to determine position of body organs like hands and legs

4) Prevention of the unionization of the cerebral cortex and the motor neurons

Every Fiber tract found in the human body system play a vital role in the overall functioning of the human therefore when any of the fiber tract is mutilated ( cut ) it presents some functional problems to the body.

When Dorsal column-medial lemniscal pathways is cut It would prevent the human body from receiving pain and temperature stimulus.

When Anterolateral pathways is cut the functional problem experienced is Inability to perceive touch and pressure by the person

When Spinocerebellar tracts are cut the individual will experience the Inability to determine position of body organs like hands and legs

When Pyramidal tracts are cut the functional problem experienced is the  Prevention of the unionization of the cerebral cortex and the motor neurons  located in the spinal cords

Hence we can conclude that the answers to your question are as mentioned above.

1. Dorsal column-medial lemniscal pathways - It would prevent the body from receiving stimuli related to pain and temperature: Corresponds to sensory pathways related to an organism's proprioceptive awareness. It is through these pathways that sensory stimuli and electrical impulses are transmitted from the body to the brain resulting in the display of quick and efficient responses. If cut, the individual would not be successful in receiving stimuli related to pain and temperature.

2. Anterolateral pathways - It would also prevent the sensation of pain and temperature, in addition to hindering the perception of touch and pressure: Located in the anterior part of the lateral column, this pathway is responsible for the transmission of nociceptive information, generally related to pain awareness. and temperature. Its cut would not only make it difficult to transmit these factors, but it would also make it difficult to transmit extroceptive information to the cortex.

3. Spinocerebellar pathways - would hinder information about the position of body members and joints: This pathway is located between the spinal cord and the ipsilaterally in the cerebellum. It consists of thousands of axonal fibers whose main function is to transmit information about the location of the body members, arms and legs, in addition to their joints. Its cut would make it difficult, or even prevent this information from being captured by the brain.

4. Pyramidal pathways - It would prevent the union of the cerebral cortex to the motor neurons of the spinal cord: It is formed by several axons that extend between the cerebral cortex and the spinal cord passing motor information that would be interrupted if the path was cut.
