About This Chapter
Basic Anatomy & Physiology of the Human Body - Chapter Summary
As part of the basic anatomy and physiology of the human body chapter, you will take a look at the definition, anatomy and a diagram of the planes of the human body. Analyze limbs, hands and feet in directional anatomy terminology and learn about how energy is used in the body while considering a human's energy balance.
Get familiar with muscle efficiency and how it is affected by muscle levers, and find out contributing factors towards being obese and overweight. Discover additional lesson information, such as:
- Anatomy's directional terminology
- Human homeostasis and regulation of temperature
- The human body and homeostasis
- The digestive system's upper gastrointestinal tract
- The digestive system's lower gastrointestinal tract
- GI tract and malabsorption
- Energy deficiencies and disorders of malabsorption
- Tissue structure and function and types of joint movement
Track your progress on these studies on your dashboard. We provide quizzes for self-assessment as you go through these lessons, in addition to a test at chapter completion so you can see if you understand the important lesson concepts and principles.
1. Planes of the Human Body: Definition, Anatomy & Diagram
Learn about the different ways in which your body can be divided or cut up for theoretical and practical purposes as we explore the sagittal plane, transverse plane and coronal plane.
2. Directional Terminology for Anatomy
This lesson seeks to cover several different terms used in directional terminology: ventral, dorsal, cranial, caudal, cephalic, and rostral. These anatomical terms are defined from a bipedal perspective.
3. Anatomical Directional Terminology: Anterior, Posterior and More
Find out how to properly refer to the location of things at the front and back of a person as well as above or below a certain point on the body by learning the terms anterior, posterior, superior, and inferior.
4. Anatomical Directional Terminology: Limbs, Hands & Feet
In this lesson, you'll learn how we term the different sides of our feet and hands thanks to words like dorsal, plantar and palmar. You'll also learn how we name something that is near or far away from the trunk of our body thanks to words like proximal and distal.
5. Homeostasis and Temperature Regulation in Humans
Do you wonder how your body is able to maintain a consistent temperature? Have you ever questioned why you get goosebumps when you're cold? This lesson will introduce you to homeostasis and answer your questions about body temperature regulation and reactions, like goosebumps.
6. Energy Balance: How the Body Uses Energy
Energy balance is the relationship between the energy you take in and the energy you use. Learn how you take in energy from the foods you eat and how your body uses that energy for your basal metabolism, physical activity and food digestion.
7. Digestive System I: The Upper Gastrointestinal Tract
Did you know that there are digestive enzymes in your saliva? It's true. As soon as you put a piece of food in your mouth, the digestive process begins. Join us with this first of two lessons about the human digestive system, where we'll follow food through the upper gastrointestinal tract from the mouth through the stomach.
8. Digestive System II: The Lower Gastrointestinal Tract
The lower gastrointestinal tract is the part of the digestive system that is responsible for the last part of food digestion and the expulsion of waste from the body. In this lesson, we'll look at each part of the system and what functions each serves in the process of digestion.
9. Malabsorption in the GI Tract
We will cover the major causes and processes of malabsorption in the GI tract and how they may connect with one another in different ways. This will include taking a look at the organs of the GI tract and their respective diseases.
10. Factors Contributing to Overweight and Obesity Problems
Sometimes our hands are tied with respect to what happens in life. But not always. In this lesson, you'll learn that despite the apparently uncontrollable risk factors for obesity, two important, controllable aspects may help you overcome the possibility of obesity.
11. Length-Tension Relationship in Skeletal Muscle
All skeletal muscles have a resting length. When our muscles are stretched to the ideal length, it can maximize muscular contraction. This lesson explains the length-tension relationship in skeletal muscle and explores how the arrangement of myofilaments in a sarcomere can impact tension and contraction.
12. How Muscle Levers Affect Muscle Efficiency
Muscular contraction creates force to move the weight of our body and body parts. This lesson describes the three lever systems utilized by our body to create movement. The efficiency of each lever type in terms of strength, speed and distance are identified along with examples.
13. 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.
