List of 206 Bones in Human Body

List of 206 Bones in the Human Body: The human body is a complex skeletal system comprising 206 bones. Bones are rigid connective tissues that provide structural support to the body and protect internal organs. The skull, formed by 22 bones, includes the cranium, which protects the brain and facial bones. The vertebral column, composed of 26 bones, includes cervical, thoracic, and lumbar vertebrae, along with sacrum and coccyx.

A thoracic cage of 25 bones surrounds vital organs, that consist of 24 ribs and a sternum. The appendicular skeleton, with 133 bones, consists of the upper limbs (60 bones) and lower limbs (60 bones), along with the pectoral and pelvic girdles that facilitate movement and mobility. In this article, we will study the list of 206 bones in the human body with a detailed diagram.

What is Bone?

Bones are rigid connective tissues that form the skeletal structure of vertebrates. They are composed of minerals (mainly calcium and phosphorus) and organic materials like collagen. The skeleton is divided into axial and appendicular skeleton.

The axial skeleton, consisting of 80 bones, protects internal organs, while the appendicular skeleton, comprising 126 bones, helps in movement. Axial and Appendicular Skeleton can be further subdivided into:

A. Axial skeleton (80)

• Spine
• Chest
• Head.

B. Appendicular skeleton (126)

• Arms
• Legs
• Pectoral Girdle
• Pelvic girdles’

List of 206 Bones in Human Body

A. Axial Skeleton

The axial skeleton comprises 80 bones, including the skull, vertebral column, and rib cage, providing structural support and protection to vital organs such as the brain and heart. It also serves as the axis of the body, facilitating posture and movement coordination. The axial skeleton bones list is given below:

Axial Skeleton (80)
Spine (Vertebral Column)	Chest (Thorax)	Head (Skull)
Cervical vertebrae (7)	Sternum (1 or 3)	Cranial Bones Occipital bone Parietal bones (2) Frontal bone Temporal bones (2) Ethmoid bone Sphenoid bone
Thoracic vertebrae (12)	Ribs (24, in pairs)	Facial Bones Lacrimal bones (2) Maxillae (2) Nasal bones (2) Palatine bones (2) Zygomatic bones (2) Inferior nasal concha (2) Mandible Hyoid Bone Vomer
Lumbar vertebrae (5)	Cervical ribs (present only in some individuals)	Ear Bones Malleus (2) Incus (2) Stapes (2)
Sacrum (5)
Coccyx (1)

B. Appendicular Skeleton

The appendicular skeleton consists of bones that form the limbs and their girdles, including the shoulder and pelvic girdles. It facilitates movement and provide attachment points for muscles. It plays a crucial role in locomotion and manipulation of objects.

Appendicular Skeleton (126)
Arms (Upper Limbs)	Legs (Lower Limbs)	Pectoral Girdles (Shoulder Girdles)	Pelvic Girdle (Pelvis)
Humerus (2)	Femur (2)	Clavicle (2)	Hip Bones (2)
Radius (2)	Tibia (2)	Scapula (2)
Ulna (2)	Fibula (2)
Carpals (16)	Patella (2)
Phalanges (28)	Tarsals (14)
Metacarpals (10)	Phalanges (28)
	Metatarsals (10)

Some Exceptions

Bones in a person keep on fusing till their 30s. As a result, a person’s overall number of bones is assessed differently across their lifespan. The hallux (in the toes) is not counted, but sesamoid bones like the pisiform (in the wrist) are counted.The bones of face and skull are counted as separate bone although they are fused. Variation in the anatomy such as sutural bones, cervical vertebrae, polydactyly, or oligodactyly can increase or reduce a person’s number of bones.

Functions of Bones in Human Body

The functions of the bone include:

• Bone provide structure, support and shape to the body.
• It protect vital organs such as the brain, heart, and lungs from external injuries.
• Bones along with muscles, allow various body movements and locomotion.
• Bone marrow present in the bone produces red and white blood cells and contributes to the immune system and oxygen transport.
• Bones store essential minerals like calcium and phosphorus. It regulates mineral balance in the body.
• Bones release hormones, such as osteocalcin that influences glucose metabolism and energy regulation.

Conclusion – List of 206 Bones in Human Body

The human body contains 206 bones that provide support, protection, and helps in movement. Bones are classified into various types, including long, short, flat, and irregular bones, each serving unique roles in the body’s structure and function. Understanding the anatomy and functions of these bones is crucial for maintaining overall health and well-being. The complete list of 206 bones in human body with diagram is given in this article.
