Broca's Area: Function & Definition

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.

Arcuate Fasciculus: Definition & Function

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.

Wernicke's Area: Function & Location

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.

Cranial Nerves of the Face and Mouth: Motion and Sensation Functionality

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.

The Pharynx & Larynx: Definition & Terms

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.

Anatomy of the Throat and Esophagus

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.

Hypoglossal Nerve: Function, Palsy & Damage

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.

What is Speech Pathology?

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.
