What is an example of long bone?
Long bones are mostly located in the appendicular skeleton and include bones in the lower limbs (the tibia, fibula, femur, metatarsals, and phalanges) and bones in the upper limbs (the humerus, radius, ulna, metacarpals, and phalanges)..
How do we classify bones?
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.
What is the human skeleton made of?
The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs. Bones are made of connective tissue reinforced with calcium and specialised bone cells. Most bones also contain bone marrow, where blood cells are made.
Are teeth part of the 206 bones?
Teeth consist mostly of hard, inorganic minerals like calcium. They also contain nerves, blood vessels and specialized cells. But they are not bones.
What are the major parts of the skeleton?
The skeletal system is divided into two parts: the axial skeleton and appendicular skeleton. The axial skeleton includes the skull, spinal column, ribs and sternum. The appendicular skeleton includes all upper and lower extremities, the shoulder girdle and the pelvic girdle.
What are the 2 types of skeletons?
Types of skeletons. There are two major types of skeletons: solid and fluid. Solid skeletons can be internal, called an endoskeleton, or external, called an exoskeleton, and may be further classified as pliant (elastic/movable) or rigid (hard/non-movable).
What are the 2 types of bone marrow?
Bone marrow can be 1 of 2 types, red or yellow, depending on whether it consists of mainly hematopoietic (and therefore, red-colored) tissue or fatty (and therefore a yellow-colored) tissue. Both types of bone marrow are highly vascular, being enriched with numerous blood vessels and capillaries.
What is the main purpose of skeletal muscle?
Skeletal muscles enable humans to move and perform daily activities. They play an essential role in respiratory mechanics and help in maintaining posture and balance. They also protect the vital organs in the body.

How many bones do we have?
It’s time to look at all your bones — the adult human body has 206 of them!
Are teeth bones?
Even though teeth and bones seem very similar, they are actually different. Teeth are not bones. Yes, both are white in color and they do indeed store calcium, but that’s where their similarities end.
Why is the skeleton divided into two parts?
Axial and Appendicular Skeletons The bones of the axial skeleton, along with ligaments and muscles, allow the human body to maintain its upright posture. The axial skeleton also transmits weight from the head, trunk, and upper extremities down the back to the lower extremities.
What are the 5 major parts of the skeletal system?
These are (1) the axial, comprising the vertebral column—the spine—and much of the skull, and (2) the appendicular, to which the pelvic (hip) and pectoral (shoulder) girdles and the bones and cartilages of the limbs belong.
What are the 3 main parts of the skeletal system?
The skeletal system is your body’s central framework. It consists of bones and connective tissue, including cartilage, tendons, and ligaments. It’s also called the musculoskeletal system.
What are the 5 functions of skeletal muscle?
The main functions of the muscular system are as follows:Mobility. The muscular system’s main function is to allow movement. … Stability. Muscle tendons stretch over joints and contribute to joint stability. … Posture. … Circulation. … Respiration. … Digestion. … Urination. … Childbirth.More items…•
What are the 4 main functions of skeletal muscle?
Terms in this set (4)Movement. attaches to bones to provide movement.Heat and Energy. produces heat and energy for the body.Posture. maintains posture.Protection. protects internal organs.
What are the 6 functions of skeletal muscles?
Terms in this set (6)move the skeleton. …maintain body posture. …support soft tissues. …guard body entrances/exits. …maintain body temperature. …store nutrients. …
What are the two types of bones?
There are two types of bone tissue: compact and spongy. The names imply that the two types differ in density, or how tightly the tissue is packed together.
What is the longest bone in the body?
femurThe femur is one of the most researched bones in the human anatomy and forensic medicine. As the longest bone in the human body, it is well preserved in skeletal remains.
What is the weakest bone in the body?
The lacrimal bone is perhaps the most fragile bone of the face and one of the smallest bones in the body. Spanning between the middle of each eye socket, each lacrimal is thin and scalelike and serves as support for the eye. The pair of lacrimal bones are two of the fourteen facial bones.
What type of skeleton do humans have?
endoskeletonThe human skeleton is an endoskeleton that consists of 206 bones in the adult. It has five main functions: providing support to the body, storing minerals and lipids, producing blood cells, protecting internal organs, and allowing for movement.
