Skeletal System

Sesamoid bones act to alter the direction of tendon pull by providing a smooth surface over which tendons can pass, reducing friction and enabling more efficient movement. They are typically found in locations where tendons are subject to high stress or where a change in direction is needed, such as in the hands and feet.

A lumbar laminectomy is a surgical procedure that involves removing part of the lamina, a bony structure in the spine, to relieve compression on the spinal nerves in the lower back. It is typically done to treat conditions such as spinal stenosis or herniated discs that are causing pain and other symptoms. The goal of the procedure is to reduce pressure on the nerves and alleviate pain and improve function.

Yes, false ribs are still attached to coastal cartilages. Floating ribs aren't.

The crista galli is a bony ridge located on the ethmoid bone in the skull, specifically within the cranial cavity. It is an important landmark for structures that contribute to the sense of smell.

The axial skeleton forms the long axis of the body and includes the bones of the skull, vertebral column, and rib cage. Its primary functions are to protect vital organs and provide structural support for the body.

A lucent lesion of the bone and a sclerotic lesion of the bone are both kinds of tumors found in the human body. Lucent lesions are caused by rapid bone injuries, while sclerotic lesions are when the bones start to grow a kind of wall to seclude a damaged area.

A slight crack in a bone is typically referred to as a hairline fracture. These fractures are small and may not always be visible on imaging tests right away, often requiring a period of rest for healing.

The movable base of the tongue is called the hyoid bone. It is a U-shaped bone in the neck that supports the tongue muscles and helps to control swallowing and speech.

Red blood cells, white blood cells, and platelets are formed in the bone marrow. Additionally, some white blood cells are also produced in the spleen.

Water striders have an exoskeleton, which is a hard outer covering that provides support and protection. This exoskeleton is made of chitin, a tough material that also covers insects and other arthropods.

Bones store minerals such as calcium and phosphate in the form of hydroxyapatite crystals. These minerals give bones their strength and help to maintain their structure and integrity. Proper mineral balance is essential for bone health and overall bodily functions.

Actually its still spine. The spine in anatomy is the combination of the vertebral column (the bone part) and the spinal chord (the nervous tissue part).

that may be all right and so but there is still another wscientific word for spine and and that is dorsal and lumber vertebrate

The small bones in the foot and ankle are called tarsal bones. There are seven tarsal bones: calcaneus, talus, cuboid, navicular, and the three cuneiform bones (medial, intermediate, and lateral).

No, the bones of the ribcage are not considered long bones. Long bones are typically found in the arms and legs, whereas the ribs are classified as flat bones.

The glabella belongs to the frontal bone of the skull. It is the smooth area of bone located between the eyebrows and above the nasal bridge.

The region you are referring to is called the ossification or metaphysis zone of the epiphyseal plate. In this area, new bone tissue is formed as osteoblasts replace the hyaline cartilage. This process helps in the longitudinal growth of bones during childhood and adolescence.

The first cervical vertebra is called the atlas, after the Greek mythological figure who held up the heavens. The second cervical vertebra is called the axis, as it allows the head to rotate from side to side.

A sprained ankle typically involves damage to the ligaments surrounding the ankle joint rather than a specific bone. However, in some cases, a sprained ankle can also involve a fracture in one of the ankle bones.

The rounded ends of the humerus and femur bones are called the epiphyses and help to facilitate smooth articulation and movement within joints by reducing friction. They are covered with cartilage, which helps cushion the bones and absorb shock during movement. These features contribute to the overall stability and mobility of the joints in the body.

No, bones are not magnetic. They do not contain enough iron or other magnetic materials to exhibit magnetic properties. Although bones do contain some iron, it is not in a form that would create a magnetic field.

The small focus of marrow signal alteration could indicate a localized change in the bone marrow tissue, which might be due to different factors such as inflammation, infection, trauma, or a benign lesion. Further imaging studies or clinical evaluation may be needed to determine the specific cause and potential implications.

Spurring of the superior patella refers to the presence of bony growth or osteophytes at the top part of the kneecap (patella). This can be due to conditions such as osteoarthritis and can cause pain and limited mobility in the knee joint. Treatment may involve physical therapy, anti-inflammatory medications, and in severe cases, surgery.

Both capillary waves and chop refer to small-scale waves present on the water surface. Capillary waves are waves with wavelengths less than 1.73 cm caused by surface tension, while chop refers to short, steep waves generated by wind. Both types of waves can create rough and irregular sea conditions.

In the cervical and thoracic area of your spine.

The cervical vertebrae starts right under your skull (following what's called the occipital foramen/foramen magnum). There are 7 cervical verterbrae and they end aproximatively under your neck (in the place where you feel a small circular prominence).

Right under there are the thoracic vertebrae, in the number of 12.

They end, let's say, at the upper part of your lower back.
