Ch 33: Nerve, Muscle & Specialized Cell Types for the MCAT: Help and Review

About This Chapter

The Nerve, Muscle and Specialized Cell Types chapter of this Medical College Admission Test (MCAT) Help and Review course is the simplest way to master these types of cells. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of nerve, muscle and specialized cell types.

Who's it for?

Anyone who needs help preparing for the science section of the MCAT exam will benefit from taking this course. You will be able to grasp the subject matter faster, retain critical knowledge longer and earn better grades. You're in the right place if you:

  • Have fallen behind in understanding the structure of nerve cells or the components of muscle, epithelial and connective tissues.
  • Need an efficient way to learn about nerve, muscle and specialized cell types.
  • Learn best with engaging auditory and visual tools.
  • Struggle with learning disabilities or learning differences, including autism and ADHD.
  • Experience difficulty understanding your teachers.
  • Missed class time and need to catch up.
  • Can't access extra MCAT science preparation resources at school.

How it works:

  • Start at the beginning, or identify the topics that you need help with.
  • Watch and learn from fun videos, reviewing as needed.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Submit questions to one of our instructors for personalized support if you need extra help.
  • Verify you're ready by completing the Nerve, Muscle and Specialized Cell Types 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 Nerve, Muscle and Specialized Cell Types chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any relevant question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

In this chapter, you'll learn the answers to questions including:

  • How are neurons structured, and what is their purpose?
  • What role do Schwann cells play in forming the myelin sheath?
  • Why are neuroglia cells important to neurons?
  • How does actin and myosin bonding make muscles contract?
  • What role do sarcomere and sliding filaments play in muscle contraction?
  • How are skeletal muscle fibers categorized?
  • What is the relationship between endothelial cells and tissue health?
  • How are adipose, fibrous and loose connective tissues structured?

10 Lessons in Chapter 33: Nerve, Muscle & Specialized Cell Types for the MCAT: Help and Review
The Structure and Function of Neurons

1. The Structure and Function of Neurons

In this video lesson, you'll learn about neurons, which are specialized cells in the nervous system. Check out how far neurons can send signals throughout the body and how depolarization is much like 'the wave' at a football game.

The Myelin Sheath, Schwann Cells & Nodes of Ranvier

2. The Myelin Sheath, Schwann Cells & Nodes of Ranvier

The myelin sheath is an essential part of our nervous system. Learn more about this neuron component, explore the nodes of Ranvier, and discover why Schwann cells are crucial for neuron survival.

Neuroglia: Function & Definition

3. Neuroglia: Function & Definition

In this lesson, you'll learn about the unsung heroes of your nervous system. These cells don't get a lot of attention, but without them, it would be difficult for your neurons to do their job and protect themselves against invaders.

Muscle Contraction: Actin and Myosin Bonding

4. Muscle Contraction: Actin and Myosin Bonding

Muscles contract through the action of two proteins called actin and myosin. In this lesson, you'll learn how actin and myosin filaments, in concert with regulatory proteins tropomyosin and troponin, control your voluntary movements.

The Sarcomere and Sliding Filaments in Muscular Contraction: Definition and Structures

5. The Sarcomere and Sliding Filaments in Muscular Contraction: Definition and Structures

Did you know that a sarcomere is the fundamental functional unit of striated muscle? This lesson describes the thick and thin filaments of a sarcomere and how they interact with each other to cause sarcomere shortening and muscular contraction.

Skeletal Muscle Fibers: Types and Functions

6. Skeletal Muscle Fibers: Types and Functions

Did you know most human muscles contain a mixture of fast, slow and intermediate fibers? This lesson describes the structure and function of the three muscle fiber types found in humans.

Multicellular Organisms, Tissues and Epithelium

7. Multicellular Organisms, Tissues and Epithelium

In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.

Fibrous Connective Tissue: Function & Types

8. Fibrous Connective Tissue: Function & Types

In this lesson, you'll learn about a specific type of connective tissue called fibrous connective tissue. You'll also discover the other specialized fibrous connective tissues: tendons, ligaments and fasciae.

Adipose Tissue and Loose Connective Tissue: Functions and Structures

9. Adipose Tissue and Loose Connective Tissue: Functions and Structures

This lesson explores the structure and function of two types of connective tissue: adipose tissue and loose connective tissue. You'll learn about the cells and fibers that make up each tissue and explore how these structures help our body function.

What Are Nerve Cells? - Function, Types & Structure

10. What Are Nerve Cells? - Function, Types & Structure

Nerve cells are the primary cells in the nervous system. They are responsible for relaying electrical messages to cells and tissues in other organ systems. This article discusses the functions and structures of nerve cells in the human body.
