Ch 5: Nerves & the Senses

About This Chapter

The Nerves & the Senses chapter of this Neuroanatomy: Help & Tutorials course is the simplest way to master nerves and the senses. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure you learn the essentials of nerves and the senses.

Who's It For?

Anyone who needs help learning or mastering nerves and the senses material will benefit from the lessons in this chapter. There is no faster or easier way to learn about nerves and the senses. Among those who would benefit are:

  • Students who have fallen behind in understanding nerves and the senses.
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about nerves and the senses
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How It Works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Nerves and the Senses chapter exam.

Why It Works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Nerves and the Senses chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any question about nerves and the senses. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students Will Review:

This chapter helps students review the concepts in a nerves and the senses unit of a standard science course. Topics covered include:

  • How the cranial nerves are involved in motion and sensation of the face and mouth
  • The function of the vagus nerve
  • Mechanisms of receptors in sensation
  • How messages are transmitted from receptors to the brain to create sensations
  • Types of pain and how they are transmitted and treated
  • Types, functions and components of sensory nerves
  • How the optic nerve takes information from the receptors of the eye to the brain to enable vision
  • The tiny components of the inner ear and how they work with the auditory nerve to enable hearing

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

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

Cranial nerves in the face and mouth control necessary functions related to facial expression & sensation, speaking, chewing, swallowing, and taste sensation. Learn about the cranial nerves of the face and mouth, the motion and sensation functions of each nerve, and how to recall the function and name of each cranial nerve.

Cranial Nerves: The Vagus Nerve and its Functionality

2. Cranial Nerves: The Vagus Nerve and its Functionality

The vagus nerve is one of the 12 cranial nerves and serves an important function related to the heart, lungs, and digestive tract. Explore the functionality of the vagus nerve, or cranial nerve X, its influence on the heart rate and digestive process.

Receptor Processes & Sensory Mechanisms

3. Receptor Processes & Sensory Mechanisms

Receptor processes and sensory mechanisms allow us to process the world around us. Learn about sensory information, explore perception and sensation, and discover how receptor processes work.

Sensory Coding: Getting Messages from Receptors to Your Brain

4. Sensory Coding: Getting Messages from Receptors to Your Brain

Sensory coding involves sensory receptors that get information from the world, a person's cells, and parts of the brain. Explore how messages travel from receptors to the brain and learn about sensory information, reception, coding, and transmission.

Pain: Types, Mechanisms, and Treatment

5. Pain: Types, Mechanisms, and Treatment

Pain is a sensation that the body feels when it is damaged or exposed to harmful stimuli. Learn about the mechanisms of pain and nociception, the different types of noxious stimuli, the pain's pathway in the body, and other types of pain.

Sensory Nerves: Types and Functions of Sensors and Receptors

6. Sensory Nerves: Types and Functions of Sensors and Receptors

Sensory nerves include different types of sensors and receptors with various functions. Explore differences in sensation, and learn about exteroceptors and mechanoreceptors, Pacinian and Meissner's corpuscles, Ruffini nerve endings, and Krause's end organs.

How Receptors of the Eye Conduct Information via the Optic Nerve

7. How Receptors of the Eye Conduct Information via the Optic Nerve

The receptors of the eye conduct information by catching light particles and converting the information into electrical signals that the brain can process into an image. Learn about photoreceptors, photopsin, rhodopsin, and the optic nerve.

The Sense of Sight: Motion, Nerves and Eye Movements

8. The Sense of Sight: Motion, Nerves and Eye Movements

The light entering the eyes enables the body's sense of sight to perceive motion and images through the processes in the optic nerves and the brain. Learn about the concepts of the sense of sight, the different nerves involved in seeing, and how eye movements are affected by the nerves.

The Ear: Hair Cells, Organ of Corti & the Auditory Nerve

9. The Ear: Hair Cells, Organ of Corti & the Auditory Nerve

The ear utilizes hair cells on its surfaces to catch sounds that are then sent to the auditory nerve, which in turn sends signals to the brain for interpretation of the sound that was heard in an instant. Learn about the structures and functions of the ears, such as the Organ of Corti, the hair cells of the inner ear, and how the auditory nerves process the signals to the brain.
