All about the Skeleton System

In this video, I would like I talk about the skeleton system, • including the axial and appendicular skeletons.First a couple of questions. • We have differentiated notes and a powerpoint that goes along with this video. • https://www.teacherspayteachers.com/P... • Would the rib cage or the femur be part of the axial skeleton? • What is one function of the skeleton system? • First, another question. Why did the skeleton go to the party alone? • He had no body to go with him. • The skeleton can be divided into two main sections. The axial and appendicular. • Combined our body has 206 bones • The Axial Skeleton – Is our core skeleton, it protects organs of the body and is composed of 80 bones • The Appendicular skeleton contains • 126 bones • It Is your appendages- arms and legs as well as the hip and shoulder girdles. • Bones are classified according to shape • Long Bones • Short Bones • Flat Bones • Irregular Bones • Up first, • Long Bones • Longer than they are wide • Found in your arms and legs • Examples include the Ulna, Radius, Femur, Tibia and Fibula • The Femur is the longest and strongest bone in your body • Short bones • Are fairly equal sized in width and length, similar to a cube • Found mostly in your wrists and ankles • Your foot consists of 26 bones • Flat bones are • thinner bones that can be either flat or curved • Examples of flat bones are the skull, ribs, scapula, hip and breastbone • Irregular bones • These are the odd-shaped bones needed to connect to other bones • They provide protection, for example the nerves of the spinal cord • Examples are the vertebrae. • The functions of the skeletal system • Provide support • Facilitate movement • Protect internal organs. • Help produce blood cells. • Storage for minerals and fat. • Support • Just as the steel beams of a building provide a scaffold to support its weight, the bones and cartilage of your skeletal system compose the scaffold that supports the rest of your body. • Movement • Bones facilitate movement by serving as points of attachment for your muscles • Protection of internal organs • Bones also protect internal organs from injury by covering or surrounding them. For example, your ribs protect your lungs and hear • Produce blood cells • The softer connective tissue that fills the interior of most bone is referred to as bone marrow • Red marrow is wherehematopoiesis—the production of blood cells—takes place. Red blood cells, white blood cells, and platelets are all produced in the red marrow. • Storage for minerals and fat • On a metabolic level, bone tissue performs several critical functions. • For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium, and phosphorus. • These minerals, incorporated into bone tissue, can be released back into the bloodstream to maintain levels needed to support physiological processes. • Bone matrix Here is what it looks like. • Why was the skeleton not allowed to play church music? • Because he had no organs • Let's get back to the original questions. • The rib cage would be part of the axial skeleton. • The skeleton system provides several functions including, • Protection • Support • Movement • Produce blood • Store minerals • Organized notes and hand-outs are avaliable • See the comments and thanks for watching. • MooMooMath uploads a new Math and Science video everyday • Please subscribe and share • The skeletal system • https://moomoomath.com/bones-in-human...
