All 206 Bones Of The Human Body Diagram – The human skeleton is the foundation of the body. It aids in movement, stores minerals, makes red blood cells, maintains weight and provides support and protection to internal organs such as the brain, lungs and heart. The skeletal system consists of bones, ligaments and cartilage that form the inner layer.

The human skeleton is a system of bones that hold the body together. An adult’s skeleton consists of 206 bones. Newborn babies have about 300 bones that are mostly cartilage, which turns into bone during a process called ossification.

The back surface of the bone is called the periosteum, a thin layer of connective tissue that feeds the bone. Next is a hard layer called short bone (also known as cortical bone). It’s the smooth surface you see when you look at the skeleton. The next layer is cancellous bone (often called spongy bone because of its appearance) which is made up of groups of trabeculae that provide support and strength. Bone marrow is a thick, jelly-like substance found between many bones that contains cells that can transform into red blood cells, white blood cells, and platelets.

The Human Skeletal System

Flat bones consist of cancellous bones sandwiched between two layers of smooth and flat bones, as their name suggests. Some examples of bones include many bones of the skull, pelvis and ribs, pelvis, and scapula. These bones protect the internal organs.

Long bones are usually found in the appendicular skeleton and their name refers to their shape, with a shaft and two ends. Some examples of bones include the femur, tibia and fibula, metatarsals and phalanges, humerus, ulna and radius. Long bones provide structure, movement and strength.

Abnormal bone is heterogeneous in structure and consists of thin layers of soft bone surrounding cancellous bone. The spine is made up of 33 unique bones that protect the spine. The sacrum, coccyx, sphenoid, zygomatic, maxilla, and hyoid bones are other examples of abnormal bones.

Sesamoid bones are round bones embedded in the tendons of the hands, knees, and feet that serve to protect the muscles from wear and stress. The knee patella is an example of a sesamoid bone.

How Bones Work

Sutural bones (also known as Wormian bones and abdominal bones) are accessory bones (parts of extra bone) found in the sutural part of the skull.

The axial skeleton consists of 80 bones and forms the vertical axis of the body. These include the bones of the skull, the vertebral column, and the ribs.

The appendicular cartilage consists of the remaining 126 bones of the body and attaches to the axial skeleton. This part of the skeleton facilitates movement and consists of the bones of the shoulder girdle, upper limbs, pelvic girdle and lower limbs.

A joint is where two or more bones meet and allow movement. They can be classified according to their style or function.

Classification of joints is based on the type of joint movement: synarthrosis (immovable), amphiarthrosis (movable part) and diarthrosis (movable joint). The structural classification is based on the three types of tissues that make up the joints: fibrous, cartilaginous or synovial.

Synarthrosis joints include fibrous joints; examples of these include skull sutures, such as the coronal suture. Amphiarthrosis joints include cartilaginous joints; examples of these include the pubic symphysis, a small movable joint that connects the hip bones with fibrocartilage. Diarthrosis joints include synovial joints; examples of these joints include the shoulder and elbow.

Synovial joints can be divided into several categories based on the structure and composition of the joint. These include pivot points (such as the atlas and axis of the neck), hinge points (such as the ligaments that connect the wrists, knees, and elbows), saddle joints (such as the carpometacarpal joints of the thumb), plane joints (such as the carpals of the hands together and tarsals of the feet), condyloid joints (such as the radiocarpal joint) and ball-and-socket joints (such as the shoulder and hip joints).

The skeletal system is made up of more than just bones. Cartilage is made up of about 900 ligaments. Ligaments are fibrous, tough, flexible, cord-like fibers that connect and connect joints, often attached to bones.

Ligaments of the skeleton can be divided into two types: white ligaments and yellow ligaments. White ligaments are composed of weak collagenous fibers while yellow ligaments are composed of strong fibers.

Cartilage is a resilient, rubber-like connective tissue that covers the surfaces of our joints and acts as a shock absorber, creating a thin surface on the ends of our bones. Although cartilage is strong and inflexible, it is not as strong and rigid as bone. They are, however, more flexible than ligaments and tendons.

Cartilage is found at the ends of bones where joints are located. It is also found at the ends of our ribs, in our bronchial tubes and airways, between the vertebrae and spine and in the nose and ears.

Hyaline cartilage is found around our organs and in our nose, trachea rings and the tips of our ribs. Fibrous cartilage is found in the pubic symphysis and in the vertebral disc. Elastic cartilage can be found in non-load-bearing parts of the body such as the back of the ear.

The human skeleton, the inner skeleton that acts as the framework of the body. This layer consists of many bones and cartilage. There are also fibrous bands of connective tissue—ligaments and tendons—in intimate relationship with the parts of the skeleton. This article focuses on the size and function of the adult human skeleton.

The human skeleton, like any other uterus, is made up of two main parts, each of which has a different origin than the other and each of which exhibits certain characteristics. These are (1) axial, consisting of the vertebral column—the spine—and most of the skull, and (2) appendicular, where the pelvic girdle (hip) and girdle (shoulder) are bones and cartilage. is. Discussed in this article as part of the axial skeleton is the third, visceral part, which consists of the lower jaw, some elements of the upper jaw, and branchial columns, including the hyoid bone.

Bones: Anatomy, Structure & Function

When one examines the relationship between these parts of the skeleton and the subtle parts of the human body – such as the nervous system, the immune system, the respiratory system, the cardiovascular system, and the voluntary nervous system – it becomes clear. that the function of the skeleton is threefold: support, protection, and movement. In this process, support is the first and oldest; similarly, the axial part of the skeleton is the first to change. The vertebral column, which corresponds to the notochord in lower organisms, is the main support of the head.

The central nervous system is located in the axial skeleton, the brain is well protected by the cranium and the spinal cord and vertebral column, by means of bony ligaments (arches of bones that surround the spinal cord) and connective ligaments; .

A unique feature of humans compared to other mammals is their upright posture. The human body is to some extent like a tower that moves on top of a pillar, which is represented by legs. Great benefits have been gained from this upright attitude, the master of which has been freeing the weapon for various uses. However, standing still posed many mechanical problems – especially weight. These problems had to be solved by integrating the skeletal system.

Protecting the heart, lungs, and other organs and structures of the chest causes problems in a different way than the central nervous system. These organs, whose functions include movement, expansion, and contraction, must have a smooth and flexible cover. Such a covering is provided by the thoracic cage, or rib cage, which forms the skeleton of the chest wall, or thorax. The combination of ribs and chest-piece is second to none, and it comes with a good looking (expensive) cartridge. The small joints between the ribs and the vertebrae allow the ribs to slide over the vertebrae during breathing and other activities. Movement is limited to the ligaments that connect the ribs to the vertebrae.

The third general function of the skeleton is motion. A large number of skeletal muscles are tightly attached to the skeleton, usually to at least two bones and sometimes to several bones. Thus, the movement of the body and its parts, from the line of a football player to the simple manipulators of an artist or the use of complex tools made by a craftsman, are possible in different and specific constructions. muscles and bones.

In this article the parts of the skeleton are explained in terms of their distribution in these functions. Injuries and injuries that can affect the human skeleton are described in the section on bone diseases. The average human body has 206 bones, but babies have 270 and about 8% of adults have more or less than 206.
