Joints are where two or more bones meet. They allow the rigid skeleton to move, surrounding soft tissues hold each joint together. Muscles lie over one or more joints at the lower back and extend upwards to the trunk and downwards to the pelvis. At both ends the muscle changes into a tendon by which it attaches itself to different
THE SKELETAL SYSTEM – BONES AND JOINTS The skeleton consists of axial and appendicular components. The axial skeleton consists of the skull, vertebral column and bones of the thorax, while the appendicular skeleton consists of the pectoral girdle, pelvic girdle, and bones of the upper and lower limbs. You do not have to remember the names of all the bones of the body but you should familiarise yourself with those indicated on the diagrams below. There are different categories of bones: long bones, short bones, flat bones, sesamoid bones and irregular bones. Long bones – The major bones of the arms (humerus, radius, and ulna) and the legs (the femur, tibia, and fibula) are all long bones.
The skeleton system has two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton consists of the skull, the spine, the ribs and the sternum (breastbone) and includes 80 bones. The appendicular skeleton, consisting of 126 bones, includes two limb girdles (the shoulders and pelvis) and their attached limb bones. Bones have two main purposes which are for you to stand correct instead of lying down on the floor like puddle of skin/mud. Other bones protects the delicate and sometimes the soft parts of your body.
The skeletal system is the main foundation of the human body, without this, we cannot function as human beings. “Many parts of the skeletal system help the body to move. Tendons connect to muscle to bone; ligaments connect bone to bone. Bones meet each other at joints” (Kelly, 2004). The muscular system and the skeletal system compromise each other when it comes to movements.
The skeletal system is made up of bones, cartilages, tendons and ligaments. These makes up about 20% of the total body mass. The skeleton , protection (the skull protects the brain and the rib cage supports organs such as heart and lungs), movement, mineral homeostasis (the bones store minerals such as calcium, phosphorus and magnesium), energy storage (the bone serves as an important chemical reserve and stores fats in the yellow marrow of the shaft of long bones) and haematopoiesis (all blood cells are formed in the red bone marrow of certain bones ). The muscles of the skeleton use the bones as levers for body movements and its parts. .
The human skeleton Is made up of 206 bones. The functions of the skeleton are to provide support, give our bodies shape, and provide protection to other systems and organs of the body, to provide attachments for muscles, to produce movement Joints A joint is the point where two or more bones meet. There are three main types of joints; Fibrous (immoveable), Cartilagenous (partially moveable) and the Synovial (freely moveable) joint. Fibrous joints Fibrous (synarthrodial): This type of joint is held together by only a ligament. Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints.
The axial skeleton contains the skull, spine, ribs, and the sternum and includes another 80 bones. The appendicular skeleton includes the limb girdles and their attached limb bones. This part of the skeletal system contains 126 bones, 64 in the shoulder and upper limbs. The limbs are some of the easiest bones to break as they are away from the bodies protection and seeing as we land on them awkwardly and break them. Their are many major bones in the body,im going to list the 15 that i believe are the most important ones with a muscle that attaches to it.
The brain, eyes, heart, lungs and spinal cord are all protected by your skeleton. Your cranium skull protects your brain and eyes, the ribs protect your heart and lungs and your vertebrae spine, backbones protect your spinal cord. Bones provide the structure for muscles to attach so that our bodies are able to move. Tendons are tough inelastic bands that hold attach muscle to bone. There are many differences between the male and female human skeletons.
There are two types of cartilage (a firm but flexible type of connective tissue) in the knee: hyaline and fibrous cartilage. The knee’s articular surface is covered in hyaline cartilage (also known as articular cartilage). The hyaline cartilage in the knee covers the inferior end of the femur, the top of the tibia and the posterior the patella. The hyaline cartilage is covered in viscous fluid called synovial fluid, which allows the surfaces of the bones to
Red, white blood cells along with other blood elements are produced within the red marrow, which fills the internal cavities within several bones. 4. Protection. Soft tissues and organs are often surrounded by skeletal elements. Ribs protecting the heart and lungs, the skull enclosing the brain, the vertebrae shield the spinal cord, and the pelvis cradles delicate digestive and reproductive organs.
