Question

Which of the following is/are incorrect? 1. Pseudounipolar neurons have one process that emerges from the cell body. 2. Bipolar neurons have one main dendrite and one axon and may be found in the retina. 3. Multipolar neurons have several dendrites and one axon and are the most common neuron found in the brain and spinal cord. 4. Afferent neurons carry information to effectors. 5. Motor neurons carry information about muscles to the spinal cord. 6. Interneurons connect sensory and motor neurons.

Answer 1

Answer:

Option (4) and (5).

Explanation:

Neurons is the structural and the functional unit of the nervous system. Two main types of neuron on the basis of their function are sensory neuron and motor neuron.

Sensory neuron also known as afferent neuron that helps in the transmission of impulse from the sensory receptor to the brain and spinal cord. Motor neurons helps in the transmission of nerve impulse from the central nervous system to the effector organ.

Thus, the correct answer is option (4) and (5).
