Types of Bones | Learn Skeleton Anatomy? ›

The bones of the human skeleton are classified by their shape: long bones, short bones, flat bones, sutural bones, sesamoid bones, and irregular bones (Figure 1). Figure 1. Shown are different types of bones: flat, irregular, long, short, and sesamoid.

The bones of the human skeleton are classified by their shape: long bones, short bones, flat bones, sutural bones, sesamoid bones, and irregular bones (Figure 1). Figure 1. Shown are different types of bones: flat, irregular, long, short, and sesamoid.

The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities.

There are six types of bones in the human body: long, short, flat, irregular, sesamoid and sutural.

How are they categorized? There are five types of bones in the skeleton: flat, long, short, irregular, and sesamoid.

Vertebrae: Your spine has 33 stacked vertebrae (small bones) that form the spinal canal.

Head bones: The 29 head bones consist of 8 cranial bones, 14 facial bones, the hyoid bone, and 6 auditory (ear) bones. The 8 cranial bones are the frontal, 2 parietal, occipital, 2 temporal, sphenoid, and ethmoid bones.

Your femur is the largest bone in your body. Most adult femurs are around 18 inches long. The femur is also the strongest bone in your body.

Located in the middle ear, the stapes is the smallest bone in the human body. Damage to this bone may cause partial or complete hearing loss. Before becoming recognized by the brain, sound waves must enter the auditory canal, go through the tympanic membrane (eardrum), and then enter the middle ear compartment.

A joint is the part of the body where two or more bones meet to allow movement. Generally speaking, the greater the range of movement, the higher the risk of injury because the strength of the joint is reduced. The six types of freely movable joint include ball and socket, saddle, hinge, condyloid, pivot and gliding.

How do you classify bones with example? ›

Bones can be classified according to their shapes. Long bones, such as the femur, are longer than they are wide. Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs.

The cranium, or skull, is composed of 22 bones anis d divided into two regions: the neurocranium (which protects the brain) and the viscerocranium (which forms the face). The skull also supports tendinous muscle attachments and allows neurovascular passage between intracranial and extracranial anatomy.

Each vertebra ( pl. : vertebrae) is an irregular bone with a complex structure composed of bone and some hyaline cartilage, that make up the vertebral column or spine, of vertebrates. The proportions of the vertebrae differ according to their spinal segment and the particular species.

The clavicle is otherwise called the collarbone. It is an S-shaped bone. The clavicles are located on each side of the chest. The clavicle is known as the "beauty bone" because of its location in the body.

Long bones are the most numerous in the skeletal system.

Seven bones in the neck—the cervical spine.

The vertebral column (spine) defines the animal subphylum Vertebra, or vertebrates, of the phylum Chordata. In humans, it is composed of 33 vertebrae that include 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal. Along with the skull, ribs, and sternum, these vertebrae make up the axial skeletal system.

There are four different types of bone in the human body: Long bone – has a long, thin shape. Examples include the bones of the arms and legs (excluding the wrists, ankles and kneecaps). With the help of muscles, long bones work as levers to permit movement.
