Question

If one of your classmates asked you to explain the different types of neurons that can be classified by structure, which of the following would you include in your explanation? a. Unipolar neurons are sensory neurons in which the axon splits into two branches that attach to the cell body. b. Multipolar neurons have one axon and one dendrite. c. Bipolar neurons are sensory neurons in which the axon splits into two branches that attach to the cell body. d. Unipolar neurons have one axon and many dendrites extending from the cell body.

Answer 1

The different types of neurons based on structure are unipolar, bipolar, multipolar, and pseudounipolar.

Step-by-step explanation:

Neurons can be classified into four types based on structure: unipolar, bipolar, multipolar, and pseudounipolar.

Unipolar neurons have a single process extending from the cell body, which splits into two branches.

Bipolar neurons have one axon and one dendrite extending from the cell body.

Multipolar neurons have one axon and multiple dendrites extending from the cell body, making them the most common type of neuron.

Answer 2

The different types of neurons based on structure are unipolar neurons, bipolar neurons, and multipolar neurons. Unipolar neurons, also known as pseudounipolar cells in humans, have a single process that splits into two branches. Bipolar neurons have one axon and one dendrite, while multipolar neurons have one axon and multiple dendrites.

Step-by-step explanation:

There are four basic types of neurons based on structure: unipolar, bipolar, multipolar, and pseudounipolar.

1. Unipolar neurons: These neurons have one structure that extends away from the soma (cell body). Although true unipolar neurons are found in invertebrates, in humans, they are more appropriately called pseudounipolar cells. They have a single process that splits into two branches, one connected to dendrites that receive sensory information and another that transmits this information to the spinal cord.
2. Bipolar neurons: These neurons have one axon and one dendrite extending from the soma. An example of a bipolar neuron is a retinal bipolar cell in the eye, which receives signals from photoreceptor cells and transmits them to ganglion cells in the brain.
3. Multipolar neurons: These are the most common type of neurons and have one axon and multiple dendrites. An example of a multipolar neuron is a Purkinje cell in the cerebellum, which has many branching dendrites and one axon.

Overall, these different types of neurons each have unique structures and functions in the nervous system.
