- Planes of the human body
1. Structure of the Nucleus: Nucleolus, Nuclear Membrane, and Nuclear Pores
In this lesson, we'll discuss the organization and importance of the nucleus in your cells. This is the membrane-bound structure responsible for containing all the genetic material essential to making you who you are.
2. The Ribosome: Structure, Function and Location
The ribosome is the cellular structure responsible for decoding your DNA. In this lesson, we'll learn about ribosome structure, function and location - characteristics that make it a very good genetic translator.
3. The Endomembrane System: Functions & Components
In this lesson, we'll learn about the endomembrane system, which consists of the endoplasmic reticulum and the Golgi apparatus. This system is important in making, packaging, and shipping all sorts of goodies for the cell to use!
4. The Cytoskeleton: Microtubules and Microfilaments
In this lesson, we'll learn about the cytoskeleton of your cells. This network of microtubules, intermediate filaments, and microfilaments helps different types of cells maintain a unique set of characteristics, including shape and movement.
5. Mitochondria Structure: Cristae, Matrix and Inner & Outer Membrane
If you want to make it through the day, you're going to need some energy. In this lesson, we'll learn about the organelle that supplies this energy, the mitochondrion, and why this cell structure appreciates the time you took to eat breakfast this morning!
6. How a Phospholipid Bilayer Is Both Hydrophobic and Hydrophilic
In this lesson, we will learn what gives phospholipids a dual personality. How can this molecule be both hydrophobic and hydrophilic, and why is this important to a cell?
7. The Fluid Mosaic Model of the Cell Membrane
In this lesson, we will discuss the components of the cell membrane and why the fluid mosaic model paints the best picture of its structure. We'll learn about the roles of the phospholipid bilayer, cholesterol, proteins and carbohydrates.
8. Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis
A cell membrane is selectively permeable - not permeable to everything. In this lesson, we'll talk about methods of passive transport along a concentration gradient, including simple and facilitated diffusion and osmosis.
9. Active Transport in Cells: Definition & Examples
In this lesson, we'll learn how substances are transported across the cell membrane against the concentration gradient. This might seem like an uphill battle for the cell, but all it takes is a little chemical energy and a few integral membrane proteins to kick off some active transport!
10. Endocytosis and Exocytosis Across the Cell Membrane
In this lesson, we'll discover how some cells can eat, drink, and digest their dinner through the process of endocytosis and a structure called the lysosome. In addition, we'll learn how a cell can throw out the leftovers across the cell membrane during exocytosis.
11. 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.
12. Human Skin: Layers, Function & Structure
This lesson will cover the three main layers of your skin, which includes the epidermis, dermis, and subcutis. In addition, we'll learn about other skin cells and tissue, such as adipose tissue, keratinocytes, melanocytes, and Merkel's cells.
13. What Is Epithelial Tissue? - Function, Types & Structure
This lesson will cover the different shapes and structures of epithelial tissue, including simple, columnar, cuboidal, stratified, transitional, squamous, and pseudostratified columnar epithelium.
14. 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.
15. 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.
16. Anatomical Directional Terminology: Lateral, Medial & More
Learn what it means to be on the same side as something else or on a different side altogether. In addition, find out what it means to be closer to or farther away from the middle of something as we explore the following terms: lateral, medial, ipsilateral, and contralateral.
17. 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.
18. Serous Membrane: Definition & Function
Your body has an unsung hero called the serous membrane. This lesson defines a serous membrane and explains precisely why it helps keep you alive on a daily basis!
19. Adrenergic Receptors: Alpha & Beta
Once you're done with this lesson on alpha and beta adrenergic receptors, you'll be able to explain why people carry around epinephrine auto-injectors in case of emergency.
20. Buccal Cavity: Definition, Structure & Function
This lesson goes over something called the buccal cavity. You'll learn what that actually means, where it's found in your body, as well as its structure and function.
21. What is Comparative Anatomy? - Definition & Examples
In this lesson, we'll first review evolution, then we'll look at one of the main types of evidence for evolution, comparative anatomy. We'll look at homologous, analogous, and vestigial structures, and go over examples of each.
