About This Chapter
Understanding the Speech Mechanism - Chapter Summary
From areas of the brain to anatomical structures responsible for speech, this chapter offers the opportunity to develop a full understanding of how humans develop the ability to speak. Each structure is carefully described and their role in speech is clarified. You will also find a lesson devoted to the topic of speech pathology. After you have completed your review of this chapter, you should be able to do the following:
- Define the functions of Broca's area and the arcuate fasciculus
- Describe the location and function of Wernicke's area
- Understand what the cranial nerves of the face and mouth do
- Detail the structures of the pharynx and larynx
- Provide details about the anatomy of the throat and esophagus
- Discuss the function and structure of the hypoglossal nerve
- Explain the field of speech pathology and how techniques in this field are used
This chapter consists of video and text lessons that are easily accessible at all times, from any device, and offer expert instruction. Lesson transcripts are printable if you wish to create quick reference tools. Determine if you have retained the information in each lesson by taking self-assessment quizzes as you progress through the chapter.
1. Broca's Area: Function & Definition
The brain is very complex and is composed of many crucial parts. Each of these parts perform a specific function. In this lesson you will learn about Broca's area.
2. Arcuate Fasciculus: Definition & Function
In this lesson, you will learn what the arcuate fasciculus is and where it is located. You will also learn a bit about its general functions and what happens if it is damaged or missing.
3. Wernicke's Area: Function & Location
Wernicke's area is an important part of the brain that is involved with helping us to understand spoken language. This lesson will cover where Wernicke's area is located in the brain, how it works, and a little bit about how it was discovered.
4. Cranial Nerves of the Face and Mouth: Motion and Sensation Functionality
We wouldn't be able to talk, taste, chew, or swallow without the cranial nerves of our face and mouth. Find out how these nerves help us move our tongue and enjoy everything from kissing to food to conversation.
5. The Pharynx & Larynx: Definition & Terms
This lesson will define the pharynx (nasopharynx, oropharynx, and laryngopharynx), as well as the larynx and epiglottis, their combining forms, and their major functions.
6. Anatomy of the Throat and Esophagus
After food has been partially broken down in the mouth, it moves through the pharynx, or throat, and the esophagus. In this lesson, you will learn how food is swallowed and how it is propelled by peristalsis through the esophagus.
7. Hypoglossal Nerve: Function, Palsy & Damage
This lesson covers the function and structure of the hypoglossal nerve. We will also cover some of the effects of damage to this system, including paralysis.
8. What is Speech Pathology?
Speech pathology encompasses many different aspects of not only speech, but also language and communication. This lesson will describe the field, and look at when and how the techniques of speech pathology are used.
