Skeletal System

The femur articulates with the medial and lateral condyles of the tibia. The femur is the bone commonly known as the thigh bone.

Well, lateral means "next to", which refers to the ribs (or cartilage connecting the ribs to the sternum). Depending on which portion of the sternum you are referring to, you will end up at a different rib, which are numbered from top to bottom, 1 - 7. There are 12 sets of ribs total, but only 7 are "lateral" to the sternum.

The largest ankle bone is the calcaneus, also known as the heel bone. It supports a significant amount of body weight and serves as an attachment point for various ligaments and tendons in the foot.

The circular structures in compact bone are called osteons or Haversian systems. Each osteon consists of concentric rings of bone matrix, surrounding a central canal that contains blood vessels and nerves. These structures help in the transport of nutrients and waste and provide strength to the bone.

The primary function if the ribcage is to protect the internal vital organs (heart & lungs) and to provide support for the structure of your body. Think of your position or posture if there were no ribs in the torso...

long bone

The general shape of the thoracic cage is like a slightly conical cage, narrowing at the top and expanding towards the bottom to accommodate the organs in the chest. It is composed of the sternum, ribs, and thoracic vertebrae, providing protection for the heart and lungs.

because a torn ligament is more serious than just a broken bone. But, in some cases when you brake a bone you also can tare a ligament so, that would be bad. Damaged cartilage is not serious at all because that's just the bendy stuff in your nose and ear. Hope this helped! :)

the parathyroid hormone (PTH) is released by the parathyroid gland (located behind the thyroid gland). A decrease in blood calcium causes the parathyroid gland to secrete PTH which causes the bones to release more calcium to raise blood calcium and also causes the kidneys to decrease the amount of calcium lost in urine

"The sphenoid articulates with twelve bones: four single, the vomer, ethmoid, frontal, and occipital; and four paired, the parietal, temporal, zygomatic, and palatine."

During development, bones start as cartilage models that gradually ossify, or turn into bone, through a process called ossification. This process involves the deposition of minerals and the formation of bone tissue by specialized cells called osteoblasts. As the individual grows, the bones continue to remodel and grow in size and strength until they reach their adult form.

Nausea and right back pain under the ribs may be caused by issues such as kidney stones, gallbladder problems, or liver issues. It is important to consult a healthcare provider for an accurate diagnosis and appropriate treatment.

The bone disorder you are referring to is likely to be osteoporosis. This condition involves a decrease in bone mass and density, leading to brittle bones that are more prone to fractures. Osteoporosis can be caused by a variety of factors, including hormonal changes, aging, and lifestyle choices.

If our skeleton was made up of one bone we wouldn't be able to move at all, or virtually do anything that we can do.

The bones in the human body are typically represented in a model by a rigid framework made of plastic or metal. These models can accurately depict the size, structure, and articulation of individual bones in the skeletal system.

The medial bone of the distal carpals is the pisiform bone. It is a small, pea-shaped bone located on the palmar aspect of the wrist. It articulates with the triquetrum bone and helps support the structure of the wrist joint.

tibia at the knee joint. This articulation plays a significant role in knee flexion and extension movements, as well as providing stability to the joint. The articulation between the medial condyles of the femur and tibia is essential for weight-bearing activities and overall lower limb function.

The sternum, also known as the breastbone, is the anchor point for the end of the ribs and it plays a crucial role in protecting the heart and other vital organs in the chest.

Yes, the exchange of air between the human body and the environment involves the coordinated contractions of the muscles of the rib cage and the diaphragm, which help expand and contract the lungs. When we inhale, the diaphragm and intercostal muscles contract to expand the thoracic cavity, allowing air to be drawn into the lungs. When we exhale, the diaphragm and intercostal muscles relax, causing the thoracic cavity to decrease in size and push air out of the lungs.

Usually 5, I say usually because the body has it's variances amongst individuals. but when looking at a population, 95% will have 5 fused segments. so if this is a test question just go ahead and answer 5

A TS (transverse section) of bone will display concentric rings of bone tissue called lamellae surrounding a Haversian canal. These lamellae will contain osteocytes in lacunae connected by tiny canaliculi. Additionally, you may see circumferential lamellae at the outer and inner surfaces of the bone.

The innermost part of the bone in called the Bone Marrow or inner bone

There are 2 types of bone tissue: Spongy or cancellous bone (head of most large bones, ribs, shoulder blade) and Compact (in the diaphysis or middle part of large bones). Compact bone forms the extremely hard exterior while spongy bone (also called cancellous bone) fills the hollow interior. Within the inside of the long bones is bone marrow.

The ossific centers appear in the intervals between the articular depressions for the coastal cartilages, in the following order: in the manubrium and first piece of the body, during the sixth month; in the second and third pieces of the body, during the seventh month of fetal life; in its fourth piece, during the first year after birth; and in the xiphoid process, between the fifth and eighteenth years.

Its component parts are not fused in the fetus.

Yes, the coxal bone is considered to be flat because of its wings.
