done in the bone marrow. 2. What is the difference between osteoclasts and osteoblasts? Osteoblasts create bone‚ while Osteoclasts break them down. The osteoblast is found on the surfaces of bone and is involved with bone deposition. The osteoclast is usually found in depressions (Howship’s lacunae) at the surfaces of bony tissue and is associated with bone resorption; it is a large multi-nucleated cell derived from blood monocytes 3. How many bones do we have in our body? 300 bones at birth

Description: The femur bone is the largest bone in the human body. Connecting the knee to the thigh‚ this bone plays a vital part to support walking‚ running‚ bending‚ climbing stairs and other every day activities. The main bone connects the kneecap or patella and the knee to the hipbone. While the knee pulls and pushes while walking‚ the femur bone plays a vital role in supporting it and in making movements easy and flexible. The groove of the femur bone is called femoral groove.

Between these bones are disc the absorb force between the bones by cushioning one bone from the other. Pain related to this area can happen when the bones begin to wear down and/or develop atypical growths otherwise known as bone spurs.

SKELETAL SYSTEM - the bones of your skeleton. OSSEUS TISSUE. - Bone tissue is a type of connective tissue. Your skeleton performs several important functions. - support and protection - body movement - muscles "pull" on bones - blood cell formation- hemopoiesis ’ occurs in red bone marrow - storage of inorganic salts - especially calcium phosphate‚ but also magnesium‚ sodium‚ potassium‚ carbonates and others Organization - normally 206 bones with 2 Main Divisions: AXIAL & APPENDICULAR
Premium Bone Skeletal system
The Skeleton is made up of 206 bones. There are two sections in the skeleton‚ the axial skeleton and the appendicular skeleton. The axial skeleton supports the head‚ neck and torso‚ and the appendicular supports the limbs and attaches the limbs to the rest of the body. There are five types of bones in the body‚ short bones‚ long bones‚ flat bones‚ irregular bones‚ and sesamoid bones. The skeleton has many functions. It supports the body and gives the body its shape. It allows movement to occur. The

Week 1 Chapter 1 1. What is the basic difference between anatomy and physiology? (p. 2) ANSWER: Anatomy (a-NAT-ō-mē; ana- = up; -tomy = process of cutting) is the science of structure and the relationships among structures. Physiology (fiz′-ē-OL-ō-jē; physio- = nature‚ -logy = study of) is the science of body functions‚ that is‚ how the body parts work. 2.

From the skull all the way to the toes of our feet‚ everything is important. Out of the 206 bones‚ they all form our different shapes and make us all unique. They create our framework and enables us the move and perform our different activities during our everyday life. Another thing that the skeletal system does is protects all of our vital organs. It also produces blood cells; the marrow in some bones produces these. 2.6 million Blood cells are produced a second. These blood cells are used to
