Anatomy of long bones

Examples of long bones include the femur tibia radius and ulna. Articular cartilage is the smooth white tissue that covers the ends of bones where they come together to form joints.

Yellow marrow is made mostly of fat and is found in the hollow centers of long bones such as the thigh bones.

Anatomy of long bones. Anatomy of Long Bones The long bones have a long central shaft that enlarges at the ends into epiphysis. The long bones in the legs are the femur tibia and fibula. The long bones of the arms are the radius and ulna.

Both the feet and hands have long bones in the digits the phalanges. The adult femur is the largest bone in. A long bone is a bone that has greater length than width.

A long bone has a shaft and 2 ends. Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and an epiphyseal line.

The epiphyseal line is a remnant of an area that contained. Long bones include the humerus upper arm radius forearm ulna forearm femur thigh fibula thin bone of the lower leg tibia shin bone phalanges digital bones in the hands and feet metacarpals long bones within the hand and metatarsals long bones within the feet. Besides having a significant length vs width when compared to most other bones long bones are also.

Gross Anatomy of Bones. A long bone has two main regions. The diaphysis and the epiphysis Figure 631.

The diaphysis is the hollow tubular shaft that runs between the proximal and distal ends of the bone. Inside the diaphysis is the medullary cavity which is filled with yellow bone marrow in an adult. Though different long bones have different shapes and functions they all have the same general structure.

Examples of long bones include the femur tibia radius and ulna. Lets breakdown the structure of a long bone. Articular cartilage is the smooth white tissue that covers the ends of bones where they come together to form joints.

Healthy cartilage in our joints makes it easier to move. Long bones anatomy can be explained as major 2 main parts namely diaphysis and epiphysis. Long bones have a shaft which is called diaphysis that makes up most of the bones length.

There is an epiphysis growth plate at each end of the long bones. Thus during growth of a long bone cartilaginous epiphysial plates intervene between the diaphysis and epiphyses. These growth plates are eventually replaced by bone at each of its two sides diaphysial and epiphysial.

When this occurs bone growth. Primarily they are referred to as long or short. There are 206 bones in the human skeleton not including teeth and sesamoid bones small bones found within cartilage.

This includes the head facial hyoid auditory trunk ribs and sternum. Long bones These bones develop via endochondral ossification a process in which the hyaline cartilage plate is slowly replaced. A shaft or diaphysis connects the two ends known as the epiphyses plural for epiphysis.

Yellow marrow is made mostly of fat and is found in the hollow centers of long bones such as the thigh bones. It does not make blood cells or platelets. Both yellow and red bone marrow have many small and large blood vessels and veins running through them to.

A long bone is one that is cylindrical in shape being longer than it is wide. Keep in mind however that the term describes the shape of a bone not its size. Long bones are found in the upper limbs humerus ulna radius and lower limbs femur tibia fibula as well as in the hands metacarpals phalanges and feet.

The medullary cavity is most pronounced in the long bones but it can be found in every type of bone. It is surrounded by spongy bone tissue and is lined by a thin membrane. This is the innermost.

Long bones are some of the longest bones in the body such as the Femur Humerus and Tibia but are also some of the smallest including the Metacarpals Metatarsals and Phalanges. The classification of a long bone includes having a body that is longer than it is wide with growth plates epiphysis at either end having a hard. The epiphysial fusion of bones occurs progressively from puberty to maturity.

Ossification of short bones is similar to that of the primary ossification center of long bones and only one short bone the calcaneus heel bone develops a secondary ossification center. 3136 long bone anatomy stock photos vectors and illustrations are available royalty-free.

Full of osteoblast that grow bone in width spongy bone found at ends. Light weight and has many spaces filled with red marrow. Long bones are 1 of the 5 types of bones in the human body and are defined as those that are longer than they are wide.

The majority of the appendicular skeleton is composed of long bones aside from the carpals and tarsals. In general the long bones form by endochondral ossification. Long bones are those that are longer than they are wide.

The end of the long bone is the epiphysis and the shaft is the diaphysis. When a human finishes growing these parts fuse together. The outside of the flat bone consists of a layer of connective tissue called the periosteum.

Anatomy of a Long Bone. A typical long bone shows the gross anatomical characteristics of bone. The wider section at each end of the bone is called the epiphysis plural epiphyses which is filled with spongy bone.

Red marrow fills the spaces in the spongy bone. Anatomy of long bones. A Using the femur as an example of a long bone the epiphysis is the enlarged area at either end of the bone while the diaphysis is the long shaft in the middle portion of the bone.

The metaphysis is the joining point between the epiphysis and diaphysis. Long bones are the most common bones found in the human body. They are composed mostly of compact bone and are roughly cylindrical in shape with enlarged ends filled with spongy bone.

As part of your Level 2 Anatomy and Physiology Exam you need to be aware of the structure of a long bone and know the terminology associated. A typical long bone shows the gross anatomical characteristics of bone. The structure of a long bone allows for the best visualization of all of the parts of a bone Figure 1.

A long bone has two parts. The diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone.

The surface of long bones is covered by the periosteum a membrane connecting the processes responsible for bone growth and callus formation in fractures. The compact bone or cortical which is a layer of dense bone is located below the periosteum. And underneath the compact bone is the location of the spongy bone or trabecular which contains bone marrow responsible for the production of.
