Key concepts Ratios Mathematics Biology Human body Introduction Our bodies are amazing! They are full of mysteries and surprising facts such as this one: Did you know that you are about a centimeter taller in the morning, when you have just woken up after hours of lying down, than you are in the evening? You might never have noticed it. These interesting facts only reveal themselves when you look closely, measure and compare. That is what this activity is about: recording, comparing and discovering how the human body measures up! Background Did you know that human bodies come in all sizes and forms? When you start measuring them, however, you will find our bodies show surprising similarities—and even more surprisingly, we can express these with mathematical concepts. For one thing, our bodies are quite symmetrical. When you draw a vertical line down the center of a body, the left and right sides are almost mirror images of each other. Human bodies also show interesting ratios. Ratios compare two quantities, like the size of one part of the body to the size of another part, or to the size of the whole. An example of a human body ratio is a person's arm span—the distance from the middle fingertip of the left hand to that of the right hand when stretching out both arms horizontally—to their height. This ratio is approximately a one to one ratio, meaning that a person’s arm span is about equal to their height. There are many more human body ratios; some are independent of age,...

The femur is the longest, strongest bone in your body. It plays an important role in how you stand, move and keep your balance. Femurs usually only break from serious traumas like car accidents. But if your bones are weakened by osteoporosis, you have an increased risk for fractures you might not even know about. Overview The femur is the only bone in your thigh. What is the femur? The femur is your thigh bone. It’s the longest, strongest bone in your body. It’s a critical part of your ability to stand and move. Your femur also supports lots of important muscles, tendons, Because it’s so strong, it usually takes a severe trauma like a fall or car accident to break your femur. If you do experience a fracture, you’ll likely need surgery to repair your bone and physical therapy to help you regain your strength and ability to move. Your femur, like all bones, can be affected by osteoporosis. Anatomy Where is the femur located? The femur is the only bone in your thigh. It runs from your hip to your knee. What does the femur look like? The femur has two rounded ends and a long shaft in the middle. It’s the classic shape used for bones in cartoons: A cylinder with two round bumps at each end. Even though it’s one long bone, your femur is made up of several parts. These include: Femur proximal aspect The upper (proximal) end of your femur connects to your hip joint. The proximal end (aspect) contains the: • Head. • Neck. • Greater trochanter. • Lesser trochanter. • Intertrochanter...

Share on Pinterest The question of how many joints there are in the human body is a difficult one to answer because it depends on a number of variables. This includes: • The definition of joints. Some define a joint as a point where 2 bones connect. Others suggest it is a point where bones connect for the purpose of moving body parts. • The inclusion of sesamoids. Sesamoids are bones imbedded in tendons, but not connected to other bones. The • The age of the human. Babies start out with about 270 bones. Some of these bones fuse together during growth. Adults have about 206 named bones, with 80 in the axial skeleton and 126 in the appendicular skeleton. In short, there’s no definite answer to this question. The estimated number is between 250 and 350. The human body has three main types of joints. They’re categorized by the movement they allow: • Synarthroses (immovable). These are fixed or fibrous joints. They’re defined as two or more bones in close contact that have no movement. The bones of the skull are an example. The immovable joints between the plates of the skull are known as sutures. • Amphiarthroses (slightly movable). Also known as cartilaginous joints, these joints are defined as two or more bones held so tightly together that only limited movement can take place. The • Diarthroses (freely movable). Also known as synovial joints, these joints have There are six types of freely movable diarthrosis (synovial) joints: • Ball and socket joint. Permitting movement i...

The opposite extreme is genu varum (bow-leggedness). In the general population of people without either genu valgum or genu varum, the femoral-tibial angle is about 175 degrees. The femur is the largest and thickest bone in the human body. By some measures, it is also the strongest bone in the human body. This depends on the type of measurement taken to calculate strength. Some strength tests show the temporal bone in the skull to be the strongest bone. The femur length on average is 26.74% of a person'...

The number of bones in the human body at birth is 300. However, as a child grows, some of the bones fuse together. The result is that there are 206 bones in the body of an adult human being. This difference in the number of bones helps forensic anthropologists in determining the age of an individual through the skeletal remains, mainly the skull. The various bones form the skeletal system, and the main function of the skeletal system is to provide a framework for the human body, and protect the delicate organs. List of Bones in the Human Body Frontal Bone This bone forms the forehead, the roof of the orbital cavity (eye socket), and the root of the nose. A newborn has a frontal bone that consists of two parts, separated by the frontal suture. However, the parts fuse to form a single bone, by the time a child is eight years old. Parietal Bones One bone from each side joins behind the frontal bone to form the sides and the roof of the cranium. There are 2 parietal bones, and each bone is roughly quadrilateral in shape. Temporal Bones There are 2 temporal bones in all, one on each side below the parietal bones. The temporal bones are located lateral to the temporal lobes of the brain, and each bone consists of five parts. Occipital Bone This is a single bone that is present at the back and lower part of the cranium, just behind the parietal and temporal bones. It has an oval aperture, known as the foramen magnum, through which the spinal cord enters the skull. Vertebral arter...

Human Bones, Joints and Muscles Facts: Human Bones, Joints and Muscles Facts: Your bones are composed of 31% water. Your bones, pound for pound, are 4 times stronger than concrete. A muscle called the diaphragm controls the human breathing process. Bone is stronger than some steel. Bones make up only 14% of our weight. At birth we have over 300 bones. As we grow up, some of the bones begin to fuse together as a result an adult has only 206 bones. The muscles of our body constitute 40% of our body weight. The muscles of the eye move more than 100,000 times a day. The muscles that control your eyes contract about 100,000 times a day (that’s the equivalent of giving your legs a workout by walking 50 miles). If you remove the minerals from a bone by soaking it overnight in a six percent solution of hydrochloric acid, it will become so soft, you could tie it in a knot. There are 22 bones in the human skull. The hardest bone in the human body is the jawbone. The human skeleton renews once in every three months. The human body consists of over 600 muscles. Human bone is as strong as steel but 50 times lighter. Human fingers stretch and bend about 25 million times in a normal lifetime. Human speech is produced by the interaction of 72 muscles. Humans have more facial muscles than any other animal on earth – 22 on each side of the face. It takes 17 muscles to smile and 43 to frown. It takes twice as long to lose new muscle if you stop working out than it did to gain it. Muscle tiss...
