How many bones are in a baby's spine?

A baby's spine typically has 33 individual bones called vertebrae. These vertebrae are smaller and more flexible compared to an adult's spine, allowing for growth and development.

What is the weakest bone in the body?

The tiniest one, the stirrup in the middle ear.

Where in the spine do most injuries occur?

Most spinal injuries occur in the cervical (neck) and lumbar (lower back) regions of the spine. The cervical spine is particularly vulnerable due to its mobility and range of motion, while the lumbar spine bears a lot of weight and can be prone to injury from lifting or twisting motions.

What is the bone in the top of the arm called?

The bone at the top of the arm is called the humerus. It is the long bone that runs from the shoulder to the elbow.

What happens to joints when there is no synovial fluid?

The membrane type associated with connective tissue is the synovial membrane. This important membrane type is found in the spaces between bone joints and produces a slippery substance called synovial fluid, which greatly reduces friction when joints move.
THERE WILL BE NO MOMENT IF SYNOVIAL FLUID IS ABSENT MOMENT...>

Synovial fluid lubricates hinge joints (knee, elbow and finger joints) ball-and-socket joints (shoulder, hip) and gliding joints (wrist, ankle). Without it, joints would not move freely and would become arthritic.

How does the structure of a bone make it strong yet lightweight?

Bone get their strength from a structure of calcium carbonate reinforced with protein fibers. This is analogous to the structure of reinforced concrete made of concrete reinforced with steel bars. In both cases the bulk material (calcium carbonate or concrete) provides compressive strength and the reinforcement (protein fibers or steel bars) both suppress crack growth and provide tensile strength.

In a human body how many ball and socket joints are in the pelvis?

There are two. They are at the point where the femurs and the pelvis join.

What is the function of the compact bone?

It makes the bones rocklike so that they can support the body and take care of organs. It makes up the compact outside of skeletal bones. Hope this helped!(:
Functions are to support the whole body, protect organs, provide levers for movement, and store and release chemical elements, mainly calcium

What are some important facts about arsenic?

  1. Arsenic is a naturally occurring element found in the Earth's crust.
  2. It is highly toxic to humans and can cause both acute and chronic health effects.
  3. Arsenic exposure can occur through contaminated water, food, or air, and is a significant public health concern globally.

Do women still have fewer ribs today as the Old Testament speaks of?

God took Adam's rib and made Eve, but that doesn't mean that their children are missing ribs, for the physical makeup is in the DNA, and cannot be changed by mere surgery.

Other than that, I can't think of what you are speaking. Sorry.

AnswerAs correctly mentioned above, if there was anybody short of a rib it would have been Adam, not Eve. AnswerComment on the Answers above: This only proves that the Bible is supported scientifically. The events above is evidence of the first cloning.

(... No its not.)

AnswerGenesis 2:21-22 (King James Version)

21 And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof; 22 And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man.

Cloning usually would take a period of time, while the account which, in context, was performed on the sixth day would have happened almost instantaneously. It also indicates that God made Eve himself.

In any case, Eve was perfectly formed, with all the ribs she needed, just as women today have all the ribs they need.

AnswerBoth men and women have 24 ribs (12 pairs). Notice that the Bible does NOT say how many ribs Adam had before or after his surgery, nor how many ribs Eve had. The Bible does NOT say women have fewer ribs than men. If God created Eve from one of Adam's ribs, she was created after Adam, and there is no reason to assume God would have made them with a different number.

The Bible is in no way supported by science, least of all by any of these answers.

Compound fracture of c5 and L1 of the spine?

A compound fracture involves a broken bone that protrudes through the skin. A compound fracture of the spine at C5 and L1 can be serious due to the proximity to the spinal cord. Immediate medical attention is necessary to prevent further damage and complications. Treatment may involve stabilizing the spine, possibly with surgery, and ongoing rehabilitation to regain strength and function. Regular follow-ups with a healthcare provider are crucial for monitoring progress and addressing any issues that may arise.

Where does bone growth occur?

Anywhere there CAN be bone. Eventually. The first place seems to be the clavecal . At least 7 to 12 months... However, there is ossification in the ciliary muscles just about first. Life before the eyes nearly get focused.... As a rule, almost nobody goes there. And only sort of long bones or bones that can be counted without a microscope seem to be considred. We are a people of vision, or at least sight. In short, as a people, we post-europeans, asians, and just about everybody but the Arunta, operate on the theory, that if you cant see it easy, it is probabaly not there. For the benifit of the culture, anywhere there is bone, muscle or mamalian tissue with any kind of stress and a supply of calcium to be deposited. That's a quick and dirty answer.

How many tarsal bones are in the foot?

There are 7 Tarsal Bones in the human foot: 1. Medial Cuneiform 2. Intermediate Cuneiform 3. Navicular 4. Talus (the ankle) 5. Lateral Cuneiform 6. Cuboid 7. Calcaneus (the heal) Arranged in 2 rows, 3 Proximal and 4 Distal.

Makes up less than 0.01 percent of body mass?

Trace elements like iodine, zinc, copper, and selenium make up less than 0.01% of body mass but play essential roles in various biochemical reactions and processes. While they are present in small amounts, they are crucial for maintaining overall health and normal bodily functions.

Where is the femur found?

It originates from d abdomen btwn d pectaralis major muscle n descends posterio-laterally from d pelvis to about mid-point of d inguinal ligament where it passes deep to d ligament n enters d femoral triangle

If the hyoid bone is not attached to another bone why is it so important?

The hyoid bone plays a crucial role in supporting the tongue and larynx, which are essential for swallowing and speech production. Its position and movements also impact the function of surrounding structures such as the pharynx and epiglottis. Additionally, forensic science uses the hyoid bone to determine characteristics of the deceased individual.

What is us pelvis transvaginal?

"US pelvis transvaginal" refers to a transvaginal ultrasound of the pelvic region. This imaging technique uses sound waves to create pictures of the internal organs in the pelvis, including the uterus, ovaries, and cervix. It is commonly used to diagnose conditions such as ovarian cysts, fibroids, and infertility issues.

How can you tell the approximate age of a human skull?

How many bones are there in an adult backbone?

There are 33 vertebrae in the human spine. (7 cervicals, 12 thoracic, 5 lumbar, 5 that fuse into the sacrum and 4 that fuse into the coccyx.). The sacrum and coccyx are already fused into their respective bones at birth.
There are 33 vertebrate in the human spine. There are 7 cervical, 12 thoracic, 5 lumbar, 5 that fuse into the sacrum, and 4 that fuse into the coccyx.

What are the people who put the casts on broken bones called?

What is the heaviest bone in the human body?

The heaviest bone in the human body is the femur, also known as the thigh bone. It is the longest and strongest bone in the body, providing support and mobility for activities like walking and running.

Common bone name for Costa?

The common name for the costa bone is the rib cage. These are the curved arches of the bones that extend from the spine toward the sternum.

What makes a skeleton move?

Skeletons do not move on their own. Movement is achieved through the muscles that are attached to the skeleton and controlled by signals from the nervous system, which coordinate and stimulate muscle contractions. Bones provide the structure and support for movement, but they do not have the ability to move on their own.

The human skeleton has 206 bones which is the longest?

Actually, the longest bone in the human body is the femur, which is located in the thigh. It is also the strongest bone in the body. The human skeleton has a total of 206 bones, which provide structure, protect organs, and support movement.
