— An increased mosquito population could lead to more malaria. — An increased mosquito population could lead to disease. — There would be more deaths from malaria. — more mosquito bites
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.
The correct answer is muscles can only pull.
The movement of arm takes place by the relaxation and contraction of muscles. Muscles in animals are in pair because muscles can only pull, when a pair of muscle is present in animals one muscle relaxes and the other one contracts. An example of this is biceps and triceps of arm. The triceps of the arm relaxes while the biceps of the arm contracts, this movement helps to lift the arm. The reverse also takes place in the arm.
