AnswersDriveBone type: One of the four basic bone shapes in the human skeleton. Long bones: Long bones have a tubular shaft and articular surface at each end. The major bones of the arms (humerus, radius, and ulna) and the legs (the femur, tibia, and fibula) are all long bones.
What are the types of bone?
There are 5 types of bones in the human body. These are long bones, short bones, flat bones, irregular bones and sesamoid bones.

What are the 4 types of bones and examples?
Types of Bones (Bone Types)
- Femur (leg bone)
- Tibia (leg bone)
- Fibula (leg bone)
- Humerus (arm bone)
- Ulna (arm bone)
- Radius (arm bone)

What are the four main classifications of bones?
The four bone classifications and examples of each are as follows: Long bones—femur and humerus Short bones—wrist and ankle bones Flat bones—skull, sternum, and scapula Irregular bones—vertebrae, mandible, and pelvic bones DIVISIONS OF SKELETON The human skeleton is divided into two main divisions, the axial skeleton

What kind of bone is a rib?
These bones are expanded into broad, flat plates, as in the cranium (skull), the ilium (pelvis), sternum and the rib cage. The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, hip bone (coxal bone), sternum, ribs, and scapulae.

What is the classification of bones?
The bones of the body come in a variety of sizes and shapes. 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.
5
What are the four types of joints?
4 types of movable joints
- Hinge, e.g. interphalangeal joints - fingers and toes.
- Ball and socket, e.g. hip and shoulder joints.
- Pivot, e.g. atlantoaxial joint between the atlas and axis - neck.
- Gliding (= "Condyloid" joint), e.g. between radius, scaphoid and lunate bones - wrist.
6
What are the irregular bones?
Irregular bones serve various purposes in the body, such as protection of nervous tissue (such as the vertebrae protect the spinal cord), affording multiple anchor points for skeletal muscle attachment (as with the sacrum), and maintaining pharynx and trachea support, and tongue attachment (such as the hyoid bone).
7
What are the short bones?
Carpus (bones of wrist) is classified as short bone. Short bones are designated as those bones that are as wide as they are long. Their primary function is to provide support and stability with little to no movement. They are one of five types of bones: short, long, flat, irregular and sesamoid.
8
What are three types of fractures classified by the pattern of the break?
Transverse Fracture: broken bone at right angle to bone's axis. Oblique Fracture: curved or sloped break pattern. Comminuted Fracture: bone breaks into several pieces.
9
What classification of bones are in the skull?
Sesamoid Bones
| Bone Classifications | ||
|---|---|---|
| Bone classification | Features | Examples |
| Short | Cube-like shape, approximately equal in length, width, and thickness | Carpals, tarsals |
| Flat | Thin and curved | Sternum, ribs, scapulae, cranial bones |
| Irregular | Complex shape | Vertebrae, facial bones |
10
What are the joints?
Joints, also known as articulations, are strong connections that join the bones, teeth, and cartilage of the body to one another. Each joint is specialized in its shape and structural components to control the range of motion between the parts that it connects.
11
What is the long bones?
Long bones are hard, dense bones that provide strength, structure, and mobility. The thigh bone (femur) is a long bone. A long bone has a shaft and two ends. Some bones in the fingers are classified as long bones, even though they are short in length.
12
What is the sacrum bone?
The sacrum is a large wedge shaped vertebra at the inferior end of the spine. It forms the solid base of the spinal column where it intersects with the hip bones to form the pelvis. The sacrum is a very strong bone that supports the weight of the upper body as it is spread across the pelvis and into the legs.
13
What is the function of the skeleton?
The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulation.
14
Are metacarpals long bones?
They are one of five types of bones: long, short, flat, irregular and sesamoid. The long bones include the femora, tibiae, and fibulae of the legs; the humeri, radii, and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the phalanges of the fingers and toes, and the clavicles or collar bones.
15
Where can you find the short bones in your body?
The short bones are small and cuboid shaped, many of which can be found around the extremities (hands and feet). Examples include the sesamoid bones, the tarsals of the ankle, and the carpals of the wrist.
16
What is the axial skeleton?
The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate. In the human skeleton, it consists of 80 bones and is composed of six parts; the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column.
17
Is the patella is a short bone?
Short bones are shaped roughly as a cube and contain mostly spongy bone. The outside surface is comprised of a thin layer of compact bone. Short bones are located in the hands and feet. The patella (kneecap) is also considered a short bone.
18
What is the role of a long bone?
Function of the long bones. Our long bones are hard, dense bones that provide strength, structure, and mobility, typically found in the upper and lower extremities (arms and legs). The femur (thigh bone) is a good example of a long bone.
