Skeletal System

4 curves.

two are primary curvatures, because they are present when we are born. they are

1. thoracic

2.sacral

other two curves are secondary curvatures. they develop after the birth.

1. cervical , appears when a baby begins to raise its head.

2. lumber , develops when the baby begins to walk.

cervical and lumber curvatures are concave in shape and thoracic and sacral curvatures convex in shape.

The femur, also known as the thigh bone, is the largest bone in the human body. It is located in the upper leg and helps support the body's weight and facilitate movement.

the thoracic spine is above the lumbar spine which means ALL thoracic vertebrae are superior to the lumbar vertebrae.

Yes, it's possible to have cervical mucus present at various points in your menstrual cycle. While cervical mucus changes consistency leading up to and during ovulation, it can also be present at other times due to hormonal fluctuations. It's important to not solely rely on cervical mucus as an indicator of ovulation and consider other fertility signs as well.

Baked bones and bones soaked in acid become more fragile and pliable, similar to the bones of a child with rickets. Rickets is a condition where bones are weakened and can bend and deform easily due to a lack of vitamin D, calcium, or phosphorus. The changes in the structure of baked or acid-soaked bones can mimic the characteristics of rickets in terms of flexibility and weakness.

The ribs are held together by a series of muscles and ligaments, including the intercostal muscles and the costal cartilage. These structures help support and protect the rib cage, allowing for proper movement during breathing and other activities.

Increasing the angle between two bones is called extension. This movement typically occurs in the sagittal plane and usually straightens or lengthens the joint.

This type of pain could be caused by various factors such as a muscle strain, rib injury, gallbladder issues, or even a problem with the lungs or diaphragm. It is best to consult with a healthcare provider for a proper evaluation and diagnosis.

The only bones (vertebrae) in your neck are from the spinal column. These are better known as the Cervical vertebra, of which you have seven, medically speaking they are labelled C1 - C7.

red marrow is found in spongy bone that produces all the different types of blood cells.

and yellow marrrow is in the middle of a bone annnnnnd it contains fat and nutrients, there are two types of marrow, trust me im in 7th grade and i have learned all about it, tomrow im taking a quiz and im gonna ace it

Wheelchair-bound individuals with paralyzed lower limbs develop thin and weak leg and thigh bones due to lack of weight-bearing physical activity that is needed to stimulate bone growth and strength. Weight-bearing activities help bones absorb calcium and other minerals, leading to stronger bone density. Without this stimulation, bones can become thin and weak over time.

the femur is the thighbone & there is only 1 per thigh. the lower leg has 2 bones: the tibia & the fibula.
answer your looking for is right or left depending on the view of the femur.

There is a bone at the lower and posterior part of the skull called the occipital bone, which, along with the atlas and the axis (the topmost vertebrae) forms the joint connecting the skull and spine. Answer provided by Migue Antonio.-

Rib is to chest. Just like the skull protects the head, the ribs protect the chest cavity where vital organs such as the heart and lungs are located.

High cheekbones are often associated with youthfulness and symmetrical facial features, which are considered attractive traits in many cultures. The shadows created by high cheekbones can also enhance facial aesthetics by creating definition and structure. Additionally, high cheekbones can give the face a more angular and sculpted appearance, which is often perceived as attractive.

22 Bones in the human skull

Some of the bones in the human body include the skull, sternum, ribs, vertebrae, clavicle, scapula, humerus, radius, ulna, pelvis, femur, tibia, fibula, patella, carpals, metacarpals, tarsals, metatarsals, and phalanges.

Flat bones, like the ribs and sternum, contain red bone marrow responsible for producing blood cells. Long bones, such as the femur and humerus, have red marrow in their spongy bone regions, specifically at the ends within structures called epiphyses, where it is involved in hematopoiesis.

The small U-shaped bone in the neck is known as the hyoid bone. It is unique in that it does not directly articulate with any other bones in the body, but instead serves as a point of attachment for muscles associated with the tongue and larynx. The hyoid bone plays a crucial role in speech and swallowing functions.

What lies in front of the tarsal bones is the metatarsal.

The femur, or thigh bone, is the longest and strongest bone in the human body. It supports the entire weight of the body and plays a crucial role in mobility and stability.

because an infant's bone is still growing and joining its bones.But an adult's bones have grown so they have less bones where as again a infants bones r stil growing and ther4 they hv more bones hope this helps! :)

Ribs 11 and 12 are known as floating ribs because they do not attach to the sternum like the other ribs do. Instead, they are only connected to the vertebrae in the back, giving them a floating or free-end appearance.

The six bones in the human arm are the humerus, radius, ulna, and the three bones in the wrist: the scaphoid, lunate, and triquetrum.

A typical human adult has 206 bones, while children have around 270 bones at birth. However, as a child grows, some bones fuse together, reducing the total number to 206 by the time they reach adulthood.
