Skeletal System

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.

An armlike bar of bone is called a brachial bone.

The pituitary gland rests on a bony structure called the sella turcica, which is located in a cavity at the base of the skull known as the sphenoid bone.

The knuckle-like process at the end of a bone is known as an articular surface or articular prominence. It plays a key role in forming joints and allowing for smooth movement between bones. The shape and structure of these articular surfaces vary depending on the type of joint and the specific bones involved.

The bulged end of a long bone such as the femur is called the epiphysis. It contains the growth plate, where new bone growth occurs during development. The epiphysis is important for joint stability and allows for smooth movement between bones.

Bone remodeling is primarily carried out by two types of cells: osteoblasts, which build new bone tissue, and osteoclasts, which break down old or damaged bone tissue. These cells work in a coordinated manner to maintain the balance between bone formation and resorption in order to keep the skeletal system healthy and strong.

Scoliosis is an abnormal curvature of the spine, which often is noticed in childhood to teen years. It creates an abnormal curve in the vertebral spine. In severe scoliosis, the spinal vertebra can twist or curve so drastically that it misaligns the vertebra and places pressure on the spinal cord. However, yours is mild with no misalignment of the spine, therefore, chances are that you have no spinal cord entrapment. However, you should talk to your doctor about whether you need a brace, physical therapy, or specific exercises to prevent the condition from getting worse.

Ribs are classified according to their attachment to the sternum. The first seven pairs of ribs attach directly to the sternum and are called true ribs. Ribs 8-10 have cartilage that attaches to the cartilage of the seventh rib and are called false ribs. The eleventh and twelfth ribs do not attach to the sternum and are called floating ribs.

Sphenoid Bone. Along the midline within the cranial cavity, a portion of the sphenoid bone indents to form the "saddle-shaped" Sella Turcica. The pituitary gland occupies this depression. The Sphenoid bone also contains two sphenoidal sinuses.

The pelvic bone is classified as a flat bone. It consists of the ilium, ischium, and pubis, which combine to form the pelvis. The pelvis serves as a strong foundation to support the body's weight and protect internal organs.

The RADIUS is one of two bones connecting the elbow to the wrist. Specifically, it's the one behind the thumb. see the link for a human skeleton with all the major bones labeled http://www.enchantedlearning.com/subjects/anatomy/skeleton/Skelprintout.shtml

Parietal- Either of two large, irregularly quadrilateral bones between the frontal and occipital bones that together form the sides and top of the skull

The scapula, also known as the shoulder blade, is a triangular-shaped bone that connects the humerus (upper arm bone) with the clavicle (collarbone). The clavicle is a long bone that runs horizontally across the front of the shoulder. Together, these bones play a crucial role in supporting the shoulder joint and allowing a wide range of motion in the arm.

The average human backbone is composed of 33 vertebrae. These consist of 7 cervical vertebrae in the neck, 12 thoracic vertebrae in the upper/mid-back, 5 lumbar vertebrae in the lower back, 5 fused sacral vertebrae forming the sacrum, and 4 fused coccygeal vertebrae forming the coccyx at the base.

mandible or lower jaw is the movable portion of our skull....

it's if you have a less amount of calcium that you eat. you need all part of the food range to live healthy life. but vegetarians can sometimes be healthier because they eat alot of vegetables.
