Short flat bones contain a layer of spongy bone in the middle, known as diploe. Diploe is filled with red bone marrow, which produces blood cells, and helps keep the bone light while maintaining strength and support.
What is the noise your bones make when you crack them...is it air pockets?
Actually it is air being released into the joints.
What is Function of fissure in skull?
Fissures in the skull allow for the passage of nerves and blood vessels between different regions of the brain. They also provide flexibility for the skull during childbirth and growth. Additionally, fissures help to separate and protect vulnerable areas of the brain from damage.
Connective tissue is one of the four types of tissue in traditional classifications (the others being epithelial, muscle, and nervous tissue). It is largely a category of exclusion rather than one with a precise definition, but all or most tissues in this category are similarly: -Involved in structure and support. -Derived from mesoderm, usually. -Characterized largely by the traits of non-living tissue. Blood, cartilage, and bone are usually considered connective tissue, but because they differ so substantially from the other tissues in this class, the phrase "connective tissue proper" is commonly used to exclude those three. There is also variation in the classification of embryonic connective tissues; on this page they will be treated as a third and separate category. (This is Directly from the link I posted) -Enjoy
What is the function of the navicular bone in the ankle?
Navicular bone is situated on the medial side of foot. The function of the navicular bone is to distribute the weight of the body evenly through the bones in the foot. Arteries running through the foot are also held together by these bones.
What are human bones made out of?
Human bones are primarily made of collagen, a protein that provides flexibility and strength, and calcium phosphate, a mineral that gives bones their hardness and durability. These minerals and proteins are arranged in a matrix that gives bones their structure and allows them to support the body and protect internal organs.
What enlargement of bone inside human nose is called as?
The enlargement of bone inside human nose is called the ethmoid bone. It separates the nasal cavity from the brain.
Largest bone in the human body?
The largest bone in our body is found between from knee to fingers of foot or feet . it is longest bone in any human . for your knowledge i want to tell you that there are approx 206 bones in human body and it is longest among them. length is according to height of that individual person.
No, the spine is not considered an organ. It is a bony structure that is part of the skeletal system and serves as the central support for the body, protecting the spinal cord. Organs are typically defined as structures composed of multiple tissues that perform specific functions within the body.
Why have you a sharp pain in your ribs im nowv 37 weeks pregnant and you have this pain for weeks?
Stolen from Momswhothink.com:
By 37 weeks of pregnancy, most pregnancies are considered "full term." The mucus plug is thick, yellowish, and may be tinged with blood. Always alert your care provider about any discharge.
Is the pelvis bone a long or short bone?
neither. the pelvis is made up of 3 different bones. the ilium, ischium and pubis. They comprise one side of the hip, while there should be an identical "set" on the opposite side.
While the axial bones form the vertical axis of the body, the appendicular bones are the bones that connect to this axis. Unlike axial bones, protection isn't the function of appendicular bon
- Bones of the shoulder. The bones that make up your shoulder girdle serve to connect your arms to your sternum and rib cage for stability and support. You have two clavicles (collarbones) that attach on one end to the breast plate and, on the other end, support the shoulder blades, or scapulas. The shoulder blades provide points of contact and attachment for manymuscles and the bone of each upper arm.
- Bones of the arm and hand. The entire arm appendage has three basic components: the upper arm, the lower arm and the hand. The upper arm is one long bone, the humerus. The top fits neatly into the scapula, and the lower end is connected by the elbow joint to the two bones of the lower arm: the ulna (the bone on the same side as your little finger) and the radius (the bone on the side of your thumb). The radius plays a larger role in your overall mobility and function, while your ulna provides more stability. Both the ulna and the radius connect to the wrist bones in the hand. Each hand has an impressive 27 bones: eight carpal bones that make up the wrist, five metacarpal bones that extend the length of your palm, and 14 phalanges that form four fingers with three bones each along with a single two-boned thumb.
- The pelvic girdle. When you sit down, all the weight of your upper body rests ultimately on your pelvic girdle. This tough pair of hip bones protects lower organs such as the bladder and, for women, protects the development of a fetus and facilitatesbirth. The dimensions of the pelvic girdle differ fairly significantly for men and women, as the opening in the center of the girdle must be large enough for a child to pass through.
- Bones of the thigh, leg and foot. Connecting the pelvic girdle to the lower leg is a bone in the thigh area called the femur, the longest and strongest in the body. About 25 percent of your total height is gained from the femur bone [source:Houston Museum of Natural Science]. The femur connects through the knee joint (which is covered and protected by the patella, or kneecap) to the shin bone (tibia). Slightly smaller than the tibia is the other bone in the leg, the fibula. The fibula is responsible for muscular connections, while the tibia makes sure your foot and your knee don't get any farther apart from each other. Each foot has 26 bones: seven tarsal bones that make up the ankle, five metatarsal bones that make up the body of your foot (and play a significant role in supporting your body's weight), and 14 phalanges that form -- as is the case with your fingers -- four toes with three bones each with a big toe that has two bones
How does smoking affect the health of bones?
smoking inhibits osteoblast (the rebuilding of bone) and promotes osteoclast (bone breakdown) These two process are an ongoing process within your body. Because a substance in cigarettes increases the function of one and inhibits the other you are more likely to have bone issues, such as osteoporosis.
What is the most frequently broken carpal bone?
The scaphoid bone is the most frequently broken carpal bone. It is located near the base of the thumb and is often fractured due to falls onto an outstretched hand. Early diagnosis and treatment are important to prevent complications such as avascular necrosis.
Can degenerative disc disease affect other parts of the spine?
Yes, degenerative disc disease can affect other parts of the spine, not just the intervertebral discs. It can lead to other spinal conditions such as facet joint arthritis, spinal stenosis, and spondylolisthesis due to changes in spinal alignment and mechanics.
What is the function of the rib cage?
The rib cage has two functions. It protects the organs in the torso, particularly the heart and lungs, and also helps you to breathe because it expands and contracts, thereby inflating and deflating the lungs.
To protect organs of the thoracic cavity; To form part of the thoracic cage(2009). In E. P. Solomon, Introduction to Human Anatomy and Physiology. St. Louis, Missouri: Saunders Elsevier.
How do scientists know whether skeletal remains are male or female?
If the pelvic bone is present there is a difference between the male and female pelvic bone. The female is wider on the inside to account for birthing a baby through. Answer
Also, if the skull is present, the brow on the male is typically more pronounced and thick. The lateral flare of the ramus portion of the mandible is also more pronounced in males than in females.
All bone marrow is red in color, but as a person ages, the marrow is slowly replaced by fat. Fat has a yellow color, so the appearance of the material in the medullary cavity will get more yellow as a person ages, but the marrow itself is red.
==========
Bones are usually filled with a whitish cream colored marrow. You may not know this, but the creamy marrow is used to produce white blood cells. The capillaries that enter the bone then take these newly reproduced white blood cells and replensih the bodies dying portion of cells. Although many bones possess the creamy white blood cell marrow, larger bones such as the femur and the humerus possess red marrow. This red marrow produces red blood cells, not white!
What do all the bones in both the pelvic girdle and hip bone consist of separately?
The pelvic girdle is created by two hip bones that come together and join at the symphysis pubis to create the girdle which provides support as well as protection for the lower visceral organs. The hip bones are usually referred to as the ossa coxae. The pelvic girdle is attached to the sacrum of the spinal column in the posterior region. The pelvis is constructed from the form given by the deep basin structure the ossa coxae form when they come together. The sacrum and the coccyx also give definition to this unique shape. The pelvic girdle shares the responsibility of supporting the body weight, particularly that which the spine produces. In a pregnant female body, the pelvic girdle also protects a developing fetus. The reproductive organs, the bladder, and other visceral organs are well within the framework that produces protection.
The coxa is created from 3 various bones. The ilium, the ischium, and the pubis become fused in the grown adult body. Along the lateral surface after the 3 bones have undergone ossification, a wide ovular depression receives the head of the femur. This depression or indentation is known as the acetabulum. Despite the adult process of ossification of the hip bones, these bones are still considered 3 various bones.

Cranial bones form a firm case enclosing the brain These bones join along zigzag lines known as?
sutures, which help to secure and protect the brain within the skull. The cranial bones include the frontal, parietal, temporal, occipital, sphenoid, and ethmoid bones, all of which contribute to the structure and protection of the brain.
What are the major parts of the skeletal system?
The major parts of the skeletal system are bones, cartilage, tendons, and ligaments. Bones provide structure to the body, protect organs, and support movement. Cartilage acts as a cushion between bones, tendons connect muscle to bone, and ligaments connect bone to bone, providing stability to joints.
Its the frame for our bodies, without it we'd just be like limp rages unable to move, sit, stand, anything. Plus it also serves as protection for our brains and vital organs by wrapping around and encasing them.
What are 3 vitamins that influence bone growth and development?
Vitamin D and Calcium
Vitamins A & B. Also the mineral phosphorus and the amino acid lysine.
[Edited by 0siris]
Sun exposure also activates the Vitamin D. Eventually, the activated VitD is converted to an active hormone: Calcitrol (by the kidneys), which in turn increases the absorption of Ca2+ from food, thus increasing blood calcium levels.
The recommended sun exposure is 5-30 minutes twice a week which is the equivalent to about 20,000 IU of VitD.
It's also worth noting that any sunblock greater than SPF15 blocks 99% of all exposure.
Blood vessles that supply nourishment to the bone cells in compact bones are located in what?
Blood vessels that supply nourishment to the bone cells in compact bones are located in channels called Haversian canals. These canals run parallel to the long axis of the bone and contain blood vessels and nerves that provide nourishment and innervation to the bone cells within the osteon.
