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.
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.
3. Skeletal Muscle Organization: Connective Tissue and Layers
Did you know that skeletal muscles are organized into tightly packed groups? This lesson identifies the connective tissue layers that organize skeletal muscle into fascicles, muscle fibers and myofibrils. Additionally, the microscopic structure of the sarcomere is described.
4. 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.
5. 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.
6. 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.
7. 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.
8. Bones of the Leg and Foot: Names, Anatomy & Functions
Find out about the major bones which help you walk. We'll go over the femur, patella, fibula, tibia, tarsals, metatarsals, and something called the trochanter.
9. Bones of the Pelvis: Definition and Function
In this lesson, you will learn about your hips and the important structures involved in their formation. The ilium, ischium, pubis, acetabulum, pelvic cavity, and sacrum will all be covered.
10. Bones of the Vertebral Column and Ribs: Definition and Function
Learn about the importance of your ribs, vertebrae, and sternum. If it wasn't for them, you wouldn't be alive. You'll also find out what strange sounding words like manubrium and xyphoid mean.
11. Bones of the Shoulder: Anatomy and Functions
Did you know that your shoulder joint is made up of many different parts? In this lesson, you'll learn about the clavicle, scapula, glenoid cavity, and acromion, as well as some of their more common names.
12. Bones of the Arm and Hand: Anatomy and Functions
The humerus isn't all that funny; it plays an important role in your body. Likewise, the radius, ulna, carpals, metacarpals and phalanges are all important components of your arm, wrist and fingers.
13. Major Bones of the Skull: Names and Location
Your eyeballs, ear and brain all depend on skull bones to give them a place to live. These bones include the frontal, parietal, occipital, temporal, sphenoid and ethmoid bone. Review these bones and their purposes in this lesson.
14. Bones of the Face: Names, Function & Location
In this lesson, learn which bones help you cry, breathe, eat and see as we review the maxilla, mandible, zygomatic, lacrimal, nasal, vomer and palatine bones of the face. Then, learn which bones are paired.
15. 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.
16. 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.
17. Anatomy of a Bone: Parts, Marrow & Types
In this lesson, you'll learn how to classify bones by their shape. Additionally, you'll discover the structural makeup of bone and the different bone markings.
18. Bone Growth & Development Factors: Endochondral Ossification
In this lesson, you will learn about the two ways we form bones: intramembranous ossification and endochondral ossification. You'll also discover how our bones grow after we're born.
19. Compact Bone: Definition, Structure & Function
In this lesson, you will learn what makes up compact bone. You'll also specifically explore the structure and location of compact bone, the densest of the two bone types.
20. Clonus: Definition, Causes & Treatment
Clonus is a condition that results in involuntary muscle spasms, most often affecting muscles at the end of the limbs. It may be a condition in and of itself or a symptom of something else.
