Skeletal System

5' was the longest human femur ever found,making him any where from 14' to 16 feet tall. King Og in the bible was 12" tall and over 4' across the shoulders.

Irregular bones serve various functions in the body, such as providing support, protection, and anchorage points for muscles. They are uniquely shaped to fit specific roles within the skeletal system, such as the vertebrae in the spine or the bones in the face.

A grasshopper's skeleton is external and is called an exoskeleton. It is made of a substance called chitin and does not contain bones. A human's skeleton is internal and in an adult contains 206 bones.

A patient healing from a broken jaw may have restrictions on their diet, such as consuming only soft or liquid foods. They may also need to avoid activities that could put strain on the jaw, such as intense chewing or speaking for extended periods. It's important for the patient to follow their healthcare provider's guidance for a successful recovery.

No, the nasal bone is a singular bone that forms the bridge of the nose. It is located between the maxilla bones.

Because ultrasound works by passing sound waves through tissue and measuring their return by deflection on a surface back to the ultrasound probe. Bone is a high density material, so reflects a high fraction of the sound waves back to the probe, making it difficult to measure different density. The lungs are filled with air, which a low density material, so the sound waves pass through the lung, and a small fraction are deflected, which makes visualising tissue very hard.

This answer is now in the museum of history of medicine. Ultrasound is very useful for lung examination in patients. It is now possible to quickly examine a patient for pulmonary edema, pneumothorax, pleural effusion, ARDS and many other diseases. Please go to google and search for "Lessnau".

Paget's disease is a chronic bone condition. In bone affected by Paget's disease, the bone remodeling is disturbed and not made right. In result the bone is formed abnormal. Pagets dieses happens to adults because their bones are older. This happens to about 1 % of adults. Scientist have not found out what causes pagets dieses. The symprtoms are arthritis Paget's disease commonly causes no symptoms. But some people have abnormally large bones which pinch their nerves causing tingling and numbness. The way pagets is treated is with a pain reliving medicine.

Synovial - the articulating bone ends are covered with articular cartilage, and enclosed within an articular capsule that is typically reinforced by ligaments externally. Internally the fibrous capsule is lined with a smooth synovial membrane that secretes synovial fluid.

The hyoid bone is a unique bone in the human body that does not directly articulate with any other bone. It is located in the neck and is attached to muscles and ligaments that help support the tongue and aid in swallowing and speaking.

Deliberately harming yourself, including by slitting your wrists, is not a safe or healthy way to cope with emotional distress. If you're experiencing thoughts of self-harm, please seek help immediately. You can reach out to a mental health professional, call a crisis helpline, or speak with a trusted friend or family member for support. There are healthier ways to deal with difficult emotions.

Bone marrow transplant is used in the treatment of noncancerous diseases such as aplastic anemia, sickle cell anemia, thalassemia, and immune system disorders like severe combined immunodeficiency (SCID) and aplastic immune deficiency. The goal of the transplant is to replace the abnormal or malfunctioning bone marrow with healthy cells to improve the patient's condition.

The axial skeleton comprises the arms and the legs. Most of the bones in the human body are located in these regions.

Arms: clavicle, scapula, humerus, ulna, radius, carpals (scaphoid, lunate, triquetrum, pisiform, hamate, capitate, trapezoid, and trapezium), 5 metacarpals, and 15 phalanges.

Legs: OS coxa, femur, patella, tibia, fibula, tarsals (talus, calcaneus, 3 cuniforms, navicular, and cuboid), 5 metatarsals, and 15 phalanges.

The two types of joints at the ends of the humerus are the elbow joint, which is a hinge joint that allows flexion and extension, and the shoulder joint, which is a ball-and-socket joint that allows a wide range of motion in multiple directions.

A rib fracture can lead to pain, difficulty breathing deeply, and an increased risk of pneumonia due to limited lung expansion. In severe cases, it can also cause damage to surrounding structures like blood vessels or organs.

The PA (posteroanterior) projection demonstrates the sternum best on an x-ray. The patient is positioned with their back against the image receptor and the x-ray beam directed from behind towards the chest, producing a frontal view of the sternum.

Bones grow in length by endochondral ossification. It begins with cartilage that acts like a model of the bone that will grow. The bone grows in length and diameter(appositional). the structure that allows this is the epiphyseal cartilage that seperates the epiphysis from the diaphysis. When the bone is fully grown this cartilage will become bone and simply the epiphyseal line.

Bone scans are ordered to detect abnormalities in the bones such as fractures, infections, tumors, and bone density issues like osteoporosis. They are often performed to diagnose bone diseases, monitor treatment response, and evaluate the extent of cancer that has spread to the bones.

Two types of tumors are benign and malignant tumors. Benign tumors are usually harmless and grow at a slow rate. However, they can grow larger and become problematic. Malignant tumors are the opposite, growing at a fast rate and causing serious health problems.

Radical neck dissection should not be used when less invasive procedures can achieve the same therapeutic goals, such as modified radical neck dissection or selective neck dissection. It should also be avoided in cases where the risks of surgery outweigh the potential benefits, such as in patients with advanced age or significant comorbidities. Additionally, it may not be appropriate in cases where the patient's quality of life would be significantly compromised by the extensive removal of neck structures.

The fluid is called synovial fluid. It lubricates the joints and reduces friction between the bones during movement.

No, bone is continually being broken down and rebuilt in a process called remodeling. Old bone is constantly being replaced with new bone tissue as part of a healthy bone turnover cycle. This process helps with bone maintenance and repair.

Phalanx is the singular term for the phalanges (bones of the fingers and toes) so there would only ever be one phalanx.

The middle finger is made up of three phalanges as are all the other fingers and toes except for the thumbs and big toes which only have two.

The sinuses are paired air pockets located within the bones of the face. They are: the ethmoid sinuses; located between the eyes, just behind the bridge of the nose.

"Cranial bones are thin and slightly curved. During infancy, these bones are held snugly together by an irregular band of connective tissue called a suture."
