Skeletal System

The term for a large rounded articulating knob is "lunate."

If you had no bones, the organ system most affected would be the musculoskeletal system. Without bones, you would have no structure or support for your muscles to attach to, making movement and posture difficult. Additionally, your bones play a role in protecting vital organs and producing blood cells.

The human hand has more bones than the human foot. The hand has 27 bones, while the foot has 26 bones.

Signs and symptoms that someone needs first aid vary greatly. If someone has fallen, pain somewhere in the body can mean that first aid is needed. If someone is laying on the floor and not responding, is bleeding from a cut, choking on food, or a host of other things, it is a sign that first aid is needed. First aid can be anything from putting a band aid on a minor cut to giving CPR. In order to know what first aid is needed for what sign or symptom, first aid training is available.

It is common for individuals to have asymmetries in their skull shape that result in bumps or irregularities. If the bump is not causing any pain or symptoms, it is likely not a cause for concern. However, if you notice any changes in size, shape, or if it causes discomfort, it is advisable to consult with a healthcare provider for a proper evaluation.

The Scapula articulates with the humerus and clavicle to make the shoulder socket.

Calcium is the nutrient that helps keep your bones and teeth strong. It is important for bone formation, density, and strength. Dairy products, leafy green vegetables, and fortified foods are good sources of calcium.

Bones grow primarily at the ends, or growth plates, where new bone tissue is formed. This process is known as endochondral ossification. Growth in length occurs through a combination of cell division and mineralization within the growth plates.

Yes, it is normal for one rib to be slightly bigger than the other due to natural anatomical variations. However, if you notice a significant difference in size or experience pain or discomfort, it is recommended to consult a healthcare professional for further evaluation.

No, the stomach does not contain cartilage. The stomach is a muscular organ that contains layers of smooth muscle tissue and specialized cells that secrete digestive enzymes and acids to aid in food digestion. Cartilage is found in joints and areas where flexibility and support are needed.

Lordosis typically affects the lumbar spine, causing an excessive inward curve. It is less common for lordosis to affect the thoracic vertebrae, as the thoracic spine naturally has a slight outward curve called kyphosis. Any abnormal curve in the thoracic spine can lead to pain and other symptoms.

Bone marrow, specifically red bone marrow, is found between the trabeculae of spongy bone. This marrow is responsible for producing blood cells, including red blood cells, white blood cells, and platelets.

Basilar skull fractures can affect the bones at the base of the skull, including the temporal, sphenoid, and occipital bones. These fractures can be serious and may cause complications such as leakage of cerebrospinal fluid or damage to cranial nerves. Prompt medical attention is essential for proper management.

Physical manifestations that may alert a physician to order images of the cranial vault for basilar skull fracture include CSF leakage from the nose or ears, raccoon eyes (periorbital ecchymosis), Battle's sign (postauricular ecchymosis), and otorrhagia (blood from the ear). These signs suggest potential trauma to the base of the skull and warrant further imaging for accurate diagnosis.

Smoking can potentially lead to a variety of health issues, some of which may include issues such as gastritis or peptic ulcer disease that could cause pain under the left side of the rib cage. However, it's important to consult with a healthcare professional to determine the exact cause of your pain.

The opening at the base of the sacral canal is called the sacral hiatus. It is formed by the absence of the lamina at the lower end of the sacrum.

The humerus articulates with the radius and ulna at the elbow joint. The trochlea of the humerus articulates with the trochlear notch of the ulna, forming a hinge joint that allows for flexion and extension. The capitulum of the humerus articulates with the head of the radius, allowing for rotation of the forearm.

The first cervical vertebra (C1), also known as the atlas, does not have a body or a spinous process. It has a ring-like structure that articulates with the skull and the axis (C2 vertebra).

Carpals do not belong as they are bones found in the wrist, while the other three - calcaneus, talus, and tarsals - are bones found in the foot.

Well, I don't know if your knee cap can just flip upside down one day, but maybe if you got seriously injured on your knee. I was born with it like that, so maybe it's just something you have always had, you just haven't noticed

The extracellular matrix consists primarily of calcium and phosphorus in the form of hydroxyapatite, Ca10(PO4)6(OH)2.

Spinalogic bone growth stimulators are typically not designed to be reprogrammed by the user. Any adjustments or reprogramming should be done by a trained healthcare professional to ensure proper function and effectiveness.

Yes, the hock joint in a cat is located at the distal end of the femur and the proximal end of the tibia. The hock joint is often compared to the human ankle joint and is essential for their agility and movement.

The increase in height in the morning compared to the evening is due to intervertebral disc hydration and spinal decompression while lying down. This effect typically lasts for about 1-2 hours after waking up before gravity compresses the spine again. The 1 cm difference is not permanent and individuals return to their evening height throughout the day.

The hyaline cartilage at the ends of long bones, known as the articular cartilage, never becomes ossified. It serves as a smooth surface for joint movement and helps distribute forces within the joint.
