Bones of the Human Body: Understand the Skeletal System

Bones of the Human Body – Understand the skeletal system and its importance in this article.

O skeletal system, or skeleton, is the set of bones that form the Human Body and is formed by rigid bone tissue. This rigidity has to do with the accumulation of calcium and magnesium (phosphate and carbonate) in intercellular spaces.

The skeleton of any vertebrate animal is responsible for:

• Support,
• Body movement,
• Protection of internal organs,
• Storage of minerals and ions and
• Blood cell production.

The bone is white in color and is living tissue, hard and dry. connects to other bones through joints and joints.

The bones of the human body are grouped through two types of skeleton: axial and appendicular, and there are variations in the shapes, sizes, width and thickness of each one.

axial skeleton – skull, ear, hyoid, rib, sternum and sternum bones. vertebrae.

Skeleton. appendicular – bones of the upper and lower limbs. The union of. axial skeleton with the appendicular occurs through the scapular and girdles. pelvic.

Amount of bones. of the human body

Ever wondered how many bones we have in our body?

An adult person has about 206 bones. All are. arranged as follows:

• Cranial bones (8),
• facial bones (14),
• Ear (3),
• neck (8),
• Chest (44),
• Abdomen (7),
• Upper limbs (62) and
• Lower limbs (60).

these 206 human body bones are divided into:

• Bones of the head (skull and face)
• neck bones
• ear bones
• Chest bones (rib, vertebrae, sternum),
• Abdominal bones (lumbar vertebrae, sacrum, coccyx),
• Bones of the lower limbs (pelvic girdle, thigh, knee, leg and foot),
• And upper limb bones (waist. scapular, arm, forearm and hand),

Unlike an adult human body, a baby's body. born with 300 more bones. However, during the process of birth and infancy, some. skull bones fuse together.

This process of solidifying the bones of one's skull. baby is the famous term we call "softwood", and over the years they do. join together forming a single bone. This happens to facilitate the baby's passage on. time of delivery and the technical term for this process is ossification.

Types of bones from. Human Body

Bones can be classified into four types: long, short, flat and irregular.

Let's define each type below:

long bones

Are those that have a length greater than the width.

short bones

It is almost the same length and width.

Flat bones

They are relatively thin bones with important regions of. muscle fixation. The main ones are: ribs, skull, sternum and scapulae.

irregular bones

They have varied and complex formats. As an example, we have the vertebrae and facial bones.

Which is the biggest among all Bones in the human body 

The femur is one of the most important bones in the body and it has. functions beyond special: is responsible for movements such as walking, crouching, jumping, running and kicking. Due to its usefulness and importance, it is the greatest. human body bone.

This bone is not fragile and can withstand great pressure, o. which helps with balance and support.

Smallest bone in the body. human

Our ear has a bone called the stapes, which is large. responsible for the hearing. This small bone measures about 0.25 cm and if. injured, the person has their hearing impaired.

The stapes is considered the smallest bone in the human body.

Now that we know the composition of bones, let's go. introduce them by name:

head bones

There are 22 bones in total, 8 from the skull (front, 2. parietal, 2 temporal, occipital, sphenoid, ethmoid) and 14 of the face (2. zygomatic, 2 maxilla, 2 nasal, mandible, 2 palatine, 2 lacrimal, vomer, 2. inferior nasal concha).

neck bones

The hyoid is the only bone we have in our neck.

ear bones

There are 6 bones in total, 2 incus, 2 malleus and 2. stirrup.

Chest Bones

There are 44 bones, 24 ribs, 12 thoracic vertebrae, 7. cervical vertebrae and 1 sternum.

Abdomen bones

There are 7 bones, 5 lumbar vertebrae, 1 sacrum and 1 coccyx.

Bones of Members. lower

There are 62 bones: 2 in the pelvic girdle, 8 in the legs (2 femur, 2. patella, 2 tibias, 2 fibulae) and 52 bones in the feet: ankle bones, calcaneus, talus, navicular, medial cuneiform, intermediate cuneiform, lateral cuneiform, cuboid, metatarsals, proximal phalanges, middle phalanges, phalanges distal. O. The femur, a bone located in the thigh, is the largest bone in the human body.

Bones of Members. Superiors

There are 64 bones, 4 in the shoulder girdle (2 collarbones and 2. shoulder blades), 6 on the arms (2 humerus, 2 ulna, 2 radius) and 54 on the hands: scaphoid, semilunar, pyramidal, pisiform, trapezius, trapezoid, capitate, hamate, metacarpals, proximal phalanx, middle phalanx, phalanx distal.

Importance of bones

Bones are very important to any animal. vertebrate, as they are the main locomotion tool. Through the. bones, we can move, support the weight of the body, we have the internal system. of protected organs and bones are still a natural reserve of minerals. (calcium and phosphorus). This is without counting the production that bones make of cells. blood.

Bones and a. food

For good bone health in the human body, it is important to pay attention to foods rich in mineral salts such as calcium and phosphorus, as both participate in the formation of the skeleton. Here are some foods that are important for the development of the bone part:

• Milk and its derivatives,
• Salmon,
• Sardine,
• Almonds,
• Spinach and other green leafy vegetables. dark
• Onion,
• Whole grain bread,
• Nut,
• Banana,
• Legumes,
• seafood,
• soy and
• Dry fruits.

glass bones

A peculiar disease of the bones is known as “bones of. glass” or “crystal bones”, and is a rare condition of connective tissue, of. genetic and hereditary character, which affects approximately one in every 20,000. people.

One of the main characteristics that defines the condition is the fragility of the bones that break with great ease. This disease has the technical term osteogenesis imperfecta (OI) and can be congenital and affect the fetus that suffers fractures while still in the mother's uterus and presents severe deformities at birth.

A movie, starring Samuel L. Jackson and Robert de Niro (Closed Body), portrays the life of a man who deals with the disease on a daily basis and how it significantly affected him.
