Skeletal System

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.

The diaphragm is the natural boundary between the thoracic and abdominopelvic cavities. It is a dome-shaped muscle that separates the thoracic cavity (containing the heart and lungs) from the abdominopelvic cavity (containing organs like the liver, stomach, and intestines).

The rate of resorption is higher in the mandible compared to the maxilla due to differences in bone density and function. The mandible is subjected to greater mechanical stress from chewing and biting forces, leading to increased remodeling and resorption. Additionally, the mandible has less trabecular bone compared to the maxilla, making it more susceptible to resorption.

Collagen provides structural support and strength to the skeletal system by forming the framework for bones and joints. It helps to maintain bone density and strength, as well as contribute to the elasticity and flexibility of joints, tendons, and ligaments.

No, bones do not grow to cover the ear canal. The ear canal is a passage made of cartilage and bone that leads to the eardrum, which is crucial for hearing. The size and shape of the ear canal can vary among individuals, but bones will not grow to obstruct it.

The abdominal cavity is the space within the abdomen that contains organs such as the stomach, liver, and intestines. It is separated from the thoracic cavity by the diaphragm, a dome-shaped muscle that helps with breathing by separating the chest from the abdomen.

SC on a spine label typically stands for "Special Collection," indicating that the item is part of a unique or rare collection within a library. It helps to differentiate these items from the general collection and may have special borrowing requirements or restrictions.

There are a total of 120 bones in all four limbs (30 bones in each arm and 30 bones in each leg).

Bones grow through a process called ossification, where new bone tissue is added to existing bone. Remodeling refers to the continuous process of breaking down and rebuilding bone tissue to maintain its strength and structure. This process is regulated by specialized cells called osteoclasts and osteoblasts.

Above your heart if you are laying down and above the belly botton if sitting down

Capillary action is a process powered by adhesion that causes water molecules to move upward through a narrow tube such as the stem of a plant. The adhesive force allows them to attach to the vessel walls.
