Similarly, what are the four main bone types?
Bone 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 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)
2
What are the two main types of bone?
A hard outer layer called cortical (compact) bone, which is strong, dense and tough. 2. A spongy inner layer called trabecular (cancellous) bone.
3
What are the classifications of bone?
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. They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities.
4
What part of your bones make blood cells?
In adults, active marrow is found inside the spine, hip and shoulder bones, ribs, breastbone, and skull. However, bone marrow found in the spine and hip has the richest source of bone marrow cells. Bone marrow is contained within bones. All blood cells are produced in the bone marrow.
5
What are the different 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 flat bones?
Flat bones are bones whose principal function is either extensive protection or the provision of broad surfaces for muscular attachment. These bones are expanded into broad, flat plates, as in the cranium (skull), the ilium (pelvis), sternum and the rib cage.
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 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).
9
What are the parts of the appendicular skeleton?
Bones of the Appendicular skeleton:
- 4 bones in the shoulder girdle (clavicle and scapula each side)
- 6 bones in the arm and forearm (humerus,ulna and radius)
- 58 bones in the hands (carpals 16, metacarpals 10, phalanges 28 and sesamoid 4)
- 2 pelvis bones.
- 8 bones in the legs (femur, tibia, patella and fibula)
10
Where is spongy bone found in the body?
Cancellous bone is made up of spongy, porous, bone tissue that is filled with red bone marrow. It is not as strong as cortical bone, which is found in the long bones, but it is very important for producing blood cells. It is found in the ends of long bones and in the bones of the pelvis, ribs, vertebrae, and skull.
11
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.
12
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.
13
How many carpal bones are in the human body?
Carpals of the left hand: There are eight carpal bones in each wrist: scaphoid, lunate, triquetral, pisiform, trapezium, trapezoid, capitate, and hamate.
14
What is the compact bone?
Compact bone, also called cortical bone, dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells. Both types are found in most bones.
15
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.
16
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.
17
What is joint?
A joint or articulation (or articular surface) is the connection made between bones in the body which link the skeletal system into a functional whole. They are constructed to allow for different degrees and types of movement.
18
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.
19
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.

What is the function of the bone?
Moreover, bone stores crucial nutrients, minerals, and lipids and produces blood cells that nourish the body and play a vital role in protecting the body against infection. All these functions make the approximately 206 bones of the human body an organ that is essential to our daily existence.
