Skeletal System

The heart is not made up of bones; it is a muscular organ primarily composed of cardiac muscle tissue. The rib cage protects the heart, which lies within the chest between the lungs and is surrounded by the sternum (breastbone) and the thoracic vertebrae in the spine.

Your left knee.

The external sheath or covering on a bone is called the periosteum. It is a fibrous membrane that contains blood vessels and nerves and helps in bone growth and repair.

Bone resorption is accomplished by specialized cells called osteoclasts. These cells are responsible for breaking down and removing old or damaged bone tissue, allowing for new bone formation and remodeling. The process of bone resorption helps regulate calcium levels in the body and is essential for maintaining bone health.

Using a syringe attached to the needle, the doctor withdraws a sample of the liquid portion of the bone marrow. You may feel a brief sharp pain or stinging. The aspiration takes only a few minutes.It depends, if you are completely out, no it won't hurt. However, if you are not completely out and/or given a local antistatic it could very well hurt.

there are 3 types of cartilage.

1Hyaline cartilage:

This type of cartilage has very thin fibers having same refractive index as the matrix of the cartilage and thus these fibers are not seen. Hyaline cartilage is the articular cartilage of long bones, sternum, ribs etc. Its color is bluish white and it is flexible.

2Fibrous cartilage:

This type of cartilage has numerous white fibers. It is present in the symphysis pubis, and sternoclavicular joint etc. Its color is glistening white and the appearance is opaque.

3Elastic cartilage:

This type of cartilage has numerous yellow elastic fibers. It is present in the ear pinna, external auditory meatus, Eustachian tubes, and epiglottis etc. Its color is yellowish and the appearance is opaque.

it is called the acetabulum (sp?) This is where the top (ball) of the femur fits into the socket (acetabulum) of the hip ... called a ball and socket joint

Four years ago I fell from a ladder and shattered my Talus bone into about eighteen recognizable pieces. Recovery time for the normal Talus fracture ranges from eight to twelve weeks. However, with a severe fracture like mine was comes AVN. Avascular Neucrosis. Excuse my spelling. AVN occurs when the Talus' blood supply has been so traumatized that it removes itself for a time, causing a dead bone. Usually the blood supply will replace itself and grow back into the bone. The time span for recovering from AVN is actually the most extensive part of recovering from a Talus fracture. Regrowth of the vascular supply ranges from six months to eighteen months depending on the case. There are machines available which speed the vascular systems regrowth. Exogen is the unit that I was able to get. January 21, 2004 was the date I broke my Talus, and I took my first steps on a uncasted foot on August 20, 2004. Many doctors will say that a Talus fracture is one of the most devastating breaks to the leg or ankle. Its no fun and will continue to hurt for life.

The hoof is more distal to the elbow. The wrist is between the elbow and hoof.

Joints may be synovial (with a cavity) or fibrous. Synovial joints are filled with synovial fluid. Fibrous joints lack this. Fibrous joints are found in between the vertebrae.

Cartilage in is both joints. This can be hylaine or fibrocartilage. Both regenerate.

The synovial fluid is rather slippery and allows easy movement in those joints. If this joint is suddenly and rapidly pulled, the fluid doesn't fill quickly and a "snapping" sound is heard.

Shin

Tendons attach muscle to bone

Ligaments attach bone to bone

i think its function is to connect your upper body to your lower body to join the both together The femur has tow functions in the human body. Is the only bone in the thigh and thus it must support all the weight of the body. It also forms an atachment sight for the muscles that act to move the thigh and the knee joint.

Cortical bone, also known as compact bone is one of two main types of osseous tissues. Cortical bone is dense and forms the surface of bones, contributing 80% of the weight of a human skeleton. It is extremely hard, formed of multiple stacked layers with few gaps.

The other major type of bone is trabecular or cancellous bone; it is spongy and makes up the bulk of the interior of most bones, including the vertebrae.

The mass that includes muscles, vital tissues, organs, and bones is called lean body mass. This includes everything in your body that isn't fat mass. Lean body mass contributes to overall health and metabolic function.

The type of bone that makes up the majority of the diaphysis of a long bone such as the humerus is compact bone. The diaphysis is the shaft of the bone that contains bone marrow and adipose tissue.

The nose bone of a human is more commonly known as the nasal bone. It is a pair of small oblong bones that form the bridge of the nose, connecting the frontal bone to the maxilla bones. The nasal bone is important for providing structure and support to the nose.

The ribs expand so that we can breathe. When the ribs expand, the volume of the pleural space increases and the lower pressure brings in air.

The process of building up and breaking down bones is called calcification. This process begins with layers of calcium that are deposited on the bones or are removed from the bones via decalcification.

a two-stage process (resorption and formation) that occurs throughout life. In the resorption stage, old bone is broken down and removed by cells called osteoclasts. In the formation stage, cells called osteoblasts build new bone to replace the old

The tissue you are describing is likely bone tissue. The pink cells would be osteoblasts or osteocytes, and the firm purple matrix would be the mineralized extracellular matrix, consisting mainly of calcium and phosphate salts.

The ulna is proximal to the carpal bones. The carpal bones are distal to the ulna.

There are 22 bones in the cranium. The bones consists of the facial bones and cranium bones. The only movable bone of the skull is the mandible.

The inferior border of the thoracic region is the bottom of the ribs. Thus all the ribs are within the thoracic region, icluding the two flaoting ribs at the bottom.
