Chapter 33, Problem 10A

Summary Introduction

To write:

The correct term that does not belong to the set and explain the reason.

Introduction:

Neurons are specialized cells that help to collect external information, analyze the information, and respond to it. Neurons make up a large signaling network, called the nervous system, in the body. A neuron mainly consists of three regions: an axon, the dendrites and a cell body. There are three groups of neurons: sensory neurons, motor neurons, and interneurons.

Explanation of Solution

The cerebrum is the largest region of the brain and is divided into two hemispheric halves. The cerebrum performs processes of thought involving learning, speech, language, memory, perception of the senses, and body movements.

The oblongata medulla transmits signals between the cerebrum and the spinal cord. It also helps in controlling respiration rate, heart rate and blood pressure.

The pons transmits signals from the cerebrum to the cerebellum. Also, the pons helps to control the breathing rate.

Conclusion

Thus, it concludes that the cerebrum does not belong to the set as the cerebrum is the region of the brain and pons and medulla oblongata is the brainstem that links the brain to the spinal cord.
