About This Chapter
1. Anatomy of the Spinal Cord: Function & Explanation
The spinal cord partners up with the brain to send information around the body as electrical signals. It tells the body what the brain wants and the brain what the body is feeling. This lesson explains how its structure helps accomplish this.
2. Dendrites: Definition & Function
Dendrites are the segments of the neuron that receive stimulation in order for the cell to become active. They conduct electrical messages to the neuron cell body for the cell to function. This lesson discusses dendrites, their function, and their importance in neuron activity.
3. What is Spina Bifida? - Definition, Types, Causes & Symptoms
Babies are sometimes born with what we call birth defects, abnormalities that can range from mild to debilitating. One of the most common is spina bifida, and it affects the spine. Learn more about spina bifida and its types, causes and symptoms.
4. Core Body Temperature: Definition & Measurement
Core body temperature refers to the temperature of the internal environment of the body. This includes organs such as the heart and liver, and the blood. Learn more about core body temperature, and take a short quiz at the end.
5. Types of Eye Diseases
This lesson gives a description of the eye and examines its anatomy. Also, this lesson will discuss diseases affecting vision as well as the parts of the eye the diseases impact.
6. What is Dermal Tissue? - Definition & Function
Dermal tissue is a thin layer of cells covering the soft parts of a plant. Learn more about the dermal tissue of a plant, and take a short quiz at the end of this lesson.
7. Adhesion Molecules: Role & Explanation
What are adhesion molecules? Learn how cells sense their environments, form connections with other cells, and move through the body. This lesson describes the main types of adhesion molecules and their roles.
8. Sensory Organs: Functions & Explanation
This lesson is about what senses are, and sensory organs that are involved in each one of the senses. Learn how stimuli trigger the senses and how stimuli reaches the brain in each case.
9. Actin Filaments: Function & Structure
The cytoskeleton provides structure and shape to cells. In this lesson, learn about actin filaments, a kind of cytoskeletal filament that is important for cell shape, muscle contraction, and cell adhesion.
10. Open Circulatory Systems: Definition & Examples
Open circulatory systems allow all fluids in an organism to mix. Learn how an open circulatory system works and explore the advantages and disadvantages of this system. Then, test your new knowledge with a quiz.
11. The Aorta: Valves & Anatomy
The aorta is the largest artery in the body. In this lesson, we'll explore where this important vessel travels in the body, discuss why it's so unique, and look at a few of its diseases.
12. What is Human Body Tissue? - Definition, Types & Examples
Human body tissue consists of groups of cells with a similar structure working together for a specific function. There are four main types of tissue in a body. Learn more about them and take a short quiz at the end of this lesson.
13. Feedback Loops in the Endocrine System
Your endocrine system regulates many important bodily functions. To do this, it relies on a constant source of information from chemical messengers in your body. This feedback is essential to proper cellular function, most of which goes on without you even noticing.
14. Retina: Definition & Function
In this lesson, you will learn about the retina of the eye and its specialized structures, as well as how it enables us to see the world in living color.
