A joint that permits no movement is known as a synarthrosis. The bones at a joint are held together by strong bands of tissue called ligaments, which allow the bones to move. The place where two or more bones come together is called a joint. The bone marrow contains stem cells, which produce the body's red blood cells and platelets.īones can move because of the way they are joined. The soft bone marrow inside many of the bones is where most of the blood cells are made. Calcium is needed to make bones hard, which allows them to support body weight. The human skeleton is composed of both fused and individual bones supported by ligaments, tendons, muscles, and cartilage.īones are made up of calcium, phosphorus, sodium, and other minerals, as well as the protein collagen. Cancellous bone, which looks like a sponge, is inside the compact bone. Compact bone is the solid, hard, outside part of the bone. There are two divisions of joints, diarthroses which allow extensive mobility between two or more articular heads, and false joints or synarthroses, immovable joints, that allow little or no movement and are predominantly fibrous. Joints: Structures that connect individual bones and may allow bones to move against each other to cause movement. Tendon: A tough, flexible band of fibrous connective tissue that connects muscles to bones. Ligaments connect the ends of bones together to form a joint. 
Ligament: A small band of dense, white, fibrous elastic tissue. It provides a cushion between bones and tendons or muscles around a joint Bursa: A small fluid-filled sac made of white fibrous tissue and lined with synovial membrane. It is made up of the body's bones (the skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue. The musculoskeletal system provides form, stability, and movement to the human body. Orthopedic surgeons use both surgical and non-surgical means to treat musculoskeletal trauma, sports injuries, degenerative diseases, infections, tumors, and congenital conditions. Plantar Fasciitis Information: Symptoms Facts and Treatment Options. Findings on How Bone Cells Respond to Forces Will Improve Repair and Prevent Future Injuries. This section also includes an additional 75 publications relating to Bones and Joints including: The bone marrow contains stem cells, which produce the body's red blood cells and platelets. 
Bones are made up of calcium, phosphorus, sodium, and other minerals, as well as the protein collagen. Over the years, the field has expanded to encompass many sub-specialties and the treatment of a wide variety of musculoskeletal disorders in patients of all ages. Orthopedic doctors specialize in diagnosis and treatment of problems of the musculoskeletal system. Orthopedics is the study of the musculoskeletal system. Synopsis: Orthopedic Information on the human musculoskeletal system including bones joints and tendons. This only works when echoing out content and not assigning to a variable.Orthopedics: Bones, Joints, Ligaments and TendonsĪuthor: Disabled World | Contact: Disabled World () Heredocs can also be used to combine variables into a string. Printf() does the same thing but will immediately display the output. It is overkill for such simple concatenation but it handy when you have a complex string and/or want to do some formatting of the data as well. Sprintf() allows us to format strings using powerful formatting options. The curly braces make it clear where the variables are. This means you can place the variables in place of the strings and just put a space in between them. their values are "swapped out" for the variable).
In PHP variables contained in double quoted strings are interpolated (i.e.
= operator: $data1 = "the color is " Ĭomplex (curly) syntax / double quotes strings If you want to append a string to another string you would use the. is the concatenation operator which returns the concatenation of its right and left arguments $data1 = "the color is" There are several ways to concatenate two strings together.
