Skeletal System

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.

Flexion decreases the angle between two bones in a joint. Extension increases that angle.

The occipital bone forms the lower back of the head. It is located at the base of the skull and helps protect the back of the brain. It also provides attachment points for muscles and ligaments involved in head and neck movement.

If it is diffuse decalcification in children, it is called as Rickets. It is called as osteomalacia in the adult. If it is patchy decalcification, it is called as osteoporosis. Bones becomes weak as a result of these changes.

(Most) humans, have 12 pairs of ribs. One pair for each of the thoracic vertebra. There is absolutely no truth to the biblical story of men having one less rib than women because Eve was created from one of Adam's ribs.

Phalanges. "Fourteen phalangeal bones constitute the four fingers and thumb (three in each finger, two in the thumb)."

Osteoclasts are the cells responsible for breaking down bone tissue in a process known as bone resorption. They secrete acid and enzymes that degrade the bone matrix, allowing for the remodelling and repair of bones.

the portion of the femur bone that helps makes up the knee cap is considered what

Hang the x-ray vertically with the toes pointing downward, with the right side of the body on the left side of the image and vice versa. This orientation is known as the anatomic position and is the standard way to view and interpret x-rays.

The smallest facial bone is known as the lacrimal bone.

The medullary cavity is the innermost part, the central cavity of the bone shaft where red and yellow bone marrow is stored.

An antrum is a cavity or chamber especially in the bone of the sinuses of the upper jaw bones, opening into the nasal cavity.

The largest bone in the arm is the humerus.
The humerus is the largest bone in the arm

A permanent structure originating from the skull is the cranium, which is the skull's part that protects the brain. The cranium consists of several bones that encase and support the brain, providing structural integrity to the skull.

No, Alzheimer's disease is a neurodegenerative disorder that primarily affects the brain, leading to memory loss and cognitive decline. Bone density is not a characteristic symptom of Alzheimer's disease.

Iron is not directly involved in bone and teeth formation. However, iron is essential for overall health, including transporting oxygen in the blood. While calcium, phosphorus, and vitamin D are more critical for strong bones and teeth, a lack of iron can lead to anemia, which may affect overall health, including bone health.

The Metal Mulisha skull is a logo associated with the Metal Mulisha brand founded by freestyle motocross rider Brian Deegan. The skull represents a rebellious and aggressive attitude often associated with extreme sports such as motocross and represents the brand's edgy and bold identity.

A suit of armor protects the body like how the skeletal system provides structure and support for the body. Just like how the armor can limit movement, the skeletal system also helps in articulating and enabling movement. Additionally, like how armor can be customized for different purposes, the skeleton can adapt to different activities and environments.

The upper jawbone is formed by the maxilla bones, which are two large bones located in the upper part of the face. These bones contribute to the structure of the face and provide support for the teeth in the upper jaw.

To manually stabilize a cervical spine, place one hand on each side of the patient's head, with your fingers supporting the jaw and your thumbs resting on the occiput (base of the skull). Hold the head in a neutral position to prevent movement that could potentially worsen a neck injury.
