What are the 3 Types of Human Skeletons?
The human skeleton is a complex and fascinating system of bones, cartilage, ligaments, and tendons that provide support, protection, and movement for the body. There are three main types of skeletons in humans: the axial skeleton, the appendicular skeleton, and the splanchnic skeleton.
The axial skeleton consists of the bones of the head, neck, and trunk. These bones include the skull, the vertebrae, the ribs, and the sternum. The axial skeleton provides protection for the brain, spinal cord, and organs, as well as support for the body's weight.
The appendicular skeleton consists of the bones of the limbs and the girdles that connect them to the axial skeleton. These bones include the humerus (upper arm bone), the radius (forearm bone), the ulna (forearm bone), the carpals (wrist bones), the metacarpals (hand bones), the phalanges (finger bones), the femur (thigh bone), the tibia (shin bone), the fibula (calf bone), the tarsals (ankle bones), the metatarsals (foot bones), and the phalanges (toe bones). The appendicular skeleton provides support and mobility for the limbs.
The splanchnic skeleton consists of the bones of the internal organs. These bones include the hyoid bone (located in the neck), the nasal conchae (located in the nose), and the auditory ossicles (located in the middle ear). The splanchnic skeleton provides support and protection for the internal organs.
