Skeletal System

You sit on the ischial tuberosity of each coxa. This is the most prominent bone marking and provides support when sitting.

The most common site for a bone marrow biopsy is the posterior iliac crest, which is the back of the hip bone.

There is no inferior process on any vertebrae, thoracic or not. There is an inferior articular facet. The inferior articular facet would articulate with the superior articular facet of the vertebrae just superior to it.

An old fracture may not show up on a bone scan if it has completely healed with no active inflammation or increased metabolic activity present at the site. The presence of old breaks on a bone scan largely depends on the healing process and the resolution of any previous damage to the bone.

Muscle is attached to bone by tendons, which are strong, fibrous tissues that connect muscle to bone. Tendons are composed of collagen fibers and transmit the force generated by muscle contraction to move the bone. This attachment allows the muscular system to work in conjunction with the skeletal system to produce movement.

Yes, it has an inner Skelton and a very define back bone. Very similar to most oceanic fish.

Long bones have adapted for stability and strength and to bear the weight of the body. The perfect example of a long bone would be the femur. The femur has a long shaft, known as the diaphysis, which is made up of compact bone. The epiphysis, or the ends of each bone are filled mostly with spongy bone except at the very outer layers and the femoral head. The trabeculae of the bones are oriented along stress lines, or areas where the stress placed on bone (like the weight of your body as you land a jump on your skateboard) can be directed out from your pelvis, down the femoral head, along the femoral neck and on down the shaft of the bone to end up being transferred your down towards your feet. So, in essence the long bones of the body are made perfectly for the transferring of stressors, or kinetic force along pathways that will do less damage, and cushion an impact.

the scientific name of the thigh bone is the femur

There are many things that can cause pain under the right side by the ribs. It can be problems with the liver, gall bladder, appendix, Crohn's disease, hernia, acid reflux, rib injury, or other issue.

The muscle that extends from the ribs to the pubis and compresses the abdomen is the Rectus Abdominis, commonly known as the "abs" or "six-pack" muscles. It helps in flexing the spine and stabilizing the core during movements.

The growth plate, also known as the epiphyseal plate, allows the diaphysis of the bone to increase in length until early childhood. During growth, the cartilage in the growth plate is replaced by bone. The articular surfaces are shaped by the action of osteoblasts and osteoclasts during development and growth.

Bone tissue is constantly being broken down and rebuilt through a process called bone remodeling. This process is regulated by cells called osteoclasts, which break down old bone, and osteoblasts, which form new bone. In addition, a healthy diet rich in calcium and vitamin D, along with regular weight-bearing exercise, can help maintain strong and healthy bones and prevent them from getting worn down.

Yes, that is correct. The paranasal sinuses are air-filled cavities within the bones of the skull, which help to reduce the weight of the skull and provide resonance for sound during speech.

The simplest answer is because the 11th and 12th ribs (the last two) don't articulate with the transverse process of their corresponding vertebrae. Thus, transverse coastal facets are not needed.

Air, fat, muscle, blood, liver, bone. The order is based on increasing radiodensity, with air being the least dense and bone being the most dense.

All human beings have the same number of ribs no matter what age. We have 12, one from each of the Thoracic vertebrae. The top 6 are called the True ribs as they connect to the Sternum via an individual piece of cartilage (its Costal Cartilage). The Next 4 are called the False ribs as all their coastal cartilages of these ribs connect to another piece of cartilage not directly to the sternum. The bottom two are called the Floating ribs as they do not have any coastal cartilage. These numbers remain the same in people of any age.

Osteoblasts and osteoclasts are two types of bone cells found in the periosteum and endosteum. Osteoblasts are involved in bone formation, while osteoclasts are responsible for breaking down old bone tissue in a process called resorption. Together, these cells play a crucial role in maintaining bone health and remodeling.

True ribs (ribs 1-7) articulate with the vertebral column at the thoracic vertebrae and also attach directly to the sternum at the front of the chest through costal cartilage. This connection provides structural support and protection for the internal organs located in the chest cavity.

Only the true ribs are attached to the sternum the false ribs (3) and the floating ribs (2) are not directly attached. The flalse ribs are attached indirectly via cartillage and the floating ribs are not attached at all.

Yes, the sternum is superficial to the heart. The sternum is a bone located in the front of the chest, while the heart is deep within the chest cavity.

Yes, a broken rib can lead to breathing problems because the pain and limited motion caused by the injury can make it difficult to take deep breaths. In severe cases, a broken rib can puncture a lung, which can cause more serious breathing issues. It is important to seek medical attention if you suspect you have a broken rib to prevent complications.

They are called Menisci. Also called shock abrosbing pads.

connect muscle to bone, allowing the muscle to transmit forces to the bone for movement. They provide stability and support during movement, acting like strong cords or cables. Tendons also help to withstand tension and facilitate proper joint function.
