Ch 28: Muscle and Skeletal Systems

About This Chapter

Review the elements of muscle and skeletal systems to prepare for the MCAT exam. Video lessons and quizzes incorporate all of the elements of the muscle and skeletal systems section in a simple and clear manner.

Muscle and Skeletal Systems - Chapter Summary

This chapter is tasked with educating you about the body's major skeletal muscle functions, as well as helping you define muscle and skeletal system terms. You will also come across video lessons that cover the following concepts:

  • Bones of the leg and foot, pelvis, arm and hand, vertebral column, ribs, shoulder and head
  • Smooth, skeletal and cardiac muscle tissue
  • Neuromuscular junction
  • Calcium-protein matrix
  • Connective tissue and layers
  • Types of joint movement

We help educate you through video lessons that are easy to understand and short. These video lessons are bundled with supplementary quizzes that were created to give you immediate feedback for revealing your weaknesses and strengths. Your results also give insight regarding your preparedness to answer questions on the MCAT's biological sciences section.

Muscle and Skeletal Systems Objectives

As stated by the MCAT muscle and skeletal systems objectives, you will need to know the following concepts:

  • Ligaments, tendons and cartilage
  • Nervous control of the muscle system
  • Skeletal structure
  • Muscle support and mobility
  • Bone growth

Along with sitting for an optional trial section and the biological sciences section, the MCAT also consists of verbal reasoning and physical sciences sections. You must answer the 52 questions on the biological sciences section before the 70-minute time limit expires. These are separated into 13 individual questions and seven question sets based on reading passages. You need to answer four to seven questions per reading passage.

Major Skeletal Muscle Functions

1. Major Skeletal Muscle Functions

Did you know that skeletal muscle does more than just move our body parts? This lesson describes how skeletal muscles are used for movement, posture, swallowing, defecation, urination and homeostasis.

Types of Muscle Tissue: Skeletal, Cardiac & Smooth

2. Types of Muscle Tissue: Skeletal, Cardiac & Smooth

Have you ever wondered why muscle has different names such as striated, smooth, voluntary, or involuntary? This lesson describes the different types of muscle tissue based on their histology, mechanism of contraction, and regulation.

The Neuromuscular Junction: Function, Structure & Physiology

3. The Neuromuscular Junction: Function, Structure & Physiology

A neuromuscular junction is a synapse between a motor neuron and skeletal muscle. This lesson describes the events of synaptic transmission leading to contraction of skeletal muscle. Myasthenia gravis is described as a neuromuscular disease.

The Skeletal System: Function and Terms

4. The Skeletal System: Function and Terms

You'll learn about the two major divisions of our skeleton, the axial and appendicular skeleton, in this video lesson. In addition, you will find out how bone is formed, thanks to tiny little cells called osteoblasts and osteoclasts, and what the major parts of a long bone are.

Joints: Structure and Functions

5. Joints: Structure and Functions

Find out what part of your body is affected when you tear your meniscus, how synovial fluid is made, what the synovial membrane helps to comprise, what a joint is, and why a joint capsule is important.

Types of Joint Movement & Tissue Structure and Function

6. Types of Joint Movement & Tissue Structure and Function

Find out how your joints are categorized. You'll learn about the synovial, cartilaginous, and fibrous joints as well as diarthrosis, synarthrosis, and amphiarthrosis.

What is Cartilage? - Definition, Types & Function

7. What is Cartilage? - Definition, Types & Function

Cartilage is a strong, flexible type of connective tissue found within a body. Learn more about its structure and function, as well as the different types of cartilage connective tissue we have in our bodies.

Bone Tissue: Functions and Types

8. Bone Tissue: Functions and Types

In this lesson, we will explore bone as a connective tissue. We will discuss the anatomy of bone, as well as the cell types which make up bone, including how bone is formed and broken down.
