How many bones in the cervical vertebrae?
There are seven cervical (C1-C7) vertebrae. The top two are unique in form and number three through seven are similar in morphology. The uppermost is the atlas (C1) which supports the skull, and the next is the axis (C2), where much if the rotation takes place. The body of the atlas is the odontoid process of the axis (c2), and the atlas (c1) rotates around this.
What is the bones connecting the skull with the hipbone called?
your pelvis is connected to your femur, your femurs connected to your patella, your patellas connected to your tibia, your tibias connected to your fibula, your fibulas connected to your tarsal bones, your tarsal bones connected to your metatarsal bones, your metatarsal bones connected to your phalanges, your phalanges are connected to.... your toe nails?
How many bones are in the face?
these 14 bones shape you face which forms our structure.
these 14 bones are called:
Sepio; which is the largest, fliopitter, laddser, liphit, fadogit ;the smallest bone,diopem,magone,puket,ninniom, tenir, yougop, werrit, pokolop and fubat.
the most important one is the tenir because it protects the soft tissues around our eyes.
Is the knee proximal or distal to the ankle?
Saying that the knee is "proximal" to the knee means it is closer to the center of the body. The construction of the leg allows us to walk. The knee couldn't be distal to the ankle because the foot would be located above the knee, which wouldn't connect to anything. It's really a matter of understanding the terminology...
How the knuckle joint is made?
Do you mean the ball joint in an automotive that is connected to the knuckle? Please write to 2459473@gmail.com for answer.
Are red blood cells produced in bones?
Red blood cells, in order to store more hemoglobin to carry oxygen, don't have a nucleus that can make repairs. So red blood cells only last, on average, 120 days. Because they constantly need to be reproduced and your bones, believe it or not, are very well vascularized, it seems like a pretty good place to store the marrow to make more red blood cells.
What are the stages of bone healing?
The first stage of ossification is the laying down of a cartilage template by chondrocytes. Then osteoblasts add calcium and phosphorus to the extracellular matrix. When that process is complete the osteoblasts become mature bone cells, osteocytes.
What is the smallest carpal bone?
The smallest carpal bone is the pisiform, located on the palmar side of the wrist. It is a sesamoid bone, meaning it develops within a tendon. It is typically the smallest and pea-shaped among the carpal bones.
What is the function of bone in the body?
Bone cells store nutrients to make our bones strong enough to support our body. Bone cells also help your hormones develope.
...
Well, I'm not sure how much the bone cells can 'store' nutrients... the cell part is small in mass/volume compared to the mineral matrix of bone itself. The cells (osteoblasts technically) more just squirt out the squishy fibers and enzymes that allow those fibers to mineralize. That mass of mineralized matrix is 'bone' in the lay sense of the word. It's hard. It's a skeleton on which all our muscles are built. But it's not a solid mass of cells like our skin or muscles are.
There are a couple cells that are within this hard bone material--they're the osteocytes. They're little pipsqueak cells that aren't really big enough to do much and they're very very stuck in one position (just like Han Solo in carbonite). But they're holding 'hands' with one another and reaching out to the cells on the surface and they're not dead (you hope. it's big trouble if they die 'cause it can lead to osteonecrosis where your bone can crumble apart. and that sucks.), so the osteocytes probably do something.
There are osteoblasts--these little guys sit on bone in a plump little line and they squirt out the fibers that make up bone. But we've already covered this, yeah?
Then there are osteoclasts. These giant fellows look something like a cross between Jabba the Hut and a Pac-Man ghost, and they really are massive. The hungry fat kids of the bone world. They're also derived from a different side of the cellular family tree than the rest of the bone cells (hematopoietic stem cells vs. mesenchymal stem cells--which is probably the only way they had the machinery to blob together into one massive used-to-be-six-cells-but-now-is-one-giant-one cell). These big guys attach to bone and eat away at the bone. The borrow through it or leave big pits. Old people have too many osteoclasts (in ratio to osteoblasts) and so their bones keep getting smaller and smaller. But let's not be too hard on the osteoclasts, 'cause we've found out recently that you can't have healthy bone without them. Something to do with 'needing to remove the old before they can call in the new'. Figures. Oh! And these are the cells that break down calcium so you can have calcium ions in your bloodstream. This is wicked important--without these ions, your muscles and nerves won't work. That would suck.
There are also other bone cells, like bone lining cells.
How have bone cells adapted to their function?
It depends on what sort of bone cell you are talking about. Osteoblasts are specialized in so far as they form new bone only, osteoclasts digest bone for remodeling however cannot form new bone. However, there are other cells in bone, such as hemaotpoietic stem cells in the bone marrow that are only specialized in so far as they produce blood cells.
What two bones articulate with the distal humerus?
The ulna and the radius articulate with the distal humerus at the elbow joint. The ulna forms the primary articulation, while the head of the radius articulates with a small depression on the side of the ulna known as the radial notch.
Compact or cortical bone is hte hard, strong layer of bone.
What is the function of sponge bone?
Cancellous bone is highly vascular and frequently contains red bone marrow where hematopoiesis, which is the production of blood cells, occurs. The primary anatomical and functional unit of cancellous bone is the trabecula.
What is the common for maxilla bone?
Do you mean the common 'name'? If yes, the common name for maxilla bone is jawbone.
What organs are located under the left rib cage?
I looked it up and it appears to be that your stomach is on the left side, as well as your spleen. If you are talking about right in front it is your stomach, near the back or on your side is the spleen. But I'm reading this from a website so don't belive me a hundred percent. But I have checked it with other sites just to be safe.
Is the skull and spinal column parts of the axial skeleton?
The axial skeleton consists of the skull, spine, ribs, and sternum. In contrast, the appendicular skeleton includes the other bones.
Why do adults bones fuse together?
Because children have more bones than adults. They is because the bones fuse together when the children are growing. A baby has 300 bones at birth. But because bones fuse together during the "growth period", adults have less bones and they end up with 206 bones.
What is the body tissue that holds bones together?
ligaments
Tendons are the tissues that hold bones together. Ligaments hold muscles to bones.
What are the parts of the vertebrae and how many bones are located in each selection?
The vertebrae consist of the vertebral body, spinous process, transverse process, and articular processes. There are 33 vertebrae in total, including 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae (fused into the sacrum), and 4 coccygeal vertebrae (fused into the coccyx).
Is the ankle distal to the phalanges?
The radius is proximal to the phalanges. The phalanges are distal to the radius.
The radius is proximal to the phalanges. The phalanges are distal to the radius.
How can you break a bone easily?
The most common ways that any bones fracture accidentally or 'naturally':
Tripping and falling (especially in sports), twisting falls, car accidents (crushing injuries), landing incorrectly, jumping from great heights, twisting injuries (arms, legs, wrists, ankles, feet) and not resting it, overuse, strong impact from a heavy object.
A fall or hit can break one or more bones of the leg(s), ankle, or foot, or of the shoulder, arm, or wrist/hand. Some of the most common circumstances are slip-falls, such as on ice, or hit-falls during sports participation.
A fall can cause fractures in the foot, hand or wrist; these kind of fractures can involve any of the small bones within the foot, hand or wrist. Depending on how strong the twist-impact was, the fracture may result in lifelong pain, swelling, and inability to fully use the joint.
Hip fractures, most common in the elderly, mostly result from imbalance when walking and from slip-falls. A fracture of the hip means immobilizing the joint and leg in a cast and remaining in bed for months.
Collar bones and ribs typically break from force-trauma, such as a traffic accident or playing sports without protective gear.
NOTE: Attempts to break your own bone can result in:
- not breaking any bone but causing....
- moderate to severe muscle problems-- often, these never heal
- nerve damage from "twist" injuries
- swelling, nerve pain, and other symptoms that result in lifelong disability called "Reflex Sympathetic Dystrophy"
- neuropathy - an intense group of "pain" symptoms ranging from intense burning to numbness, tingling, etc. etc.
ALL bone fractures carry specific risks, including:
- the need for one or more surgeries
- development of a blood clot
- the blood clot can break off and become an embolism-- a life-threatening event
- an embolism can cause Stroke, heart attack, or death
- blood or bone infection that requires hospitalization and treatment with IV antibiotics for weeks on end!
- death from blood or bone infection
As well, ALL fractures cause damage to:
- nerves
- muscles
- tissues
- and may result in muscle atrophy, where the broken limb loses muscle mass and is then permanently smaller than the non-broken limb
ALL bone fractures hurt INTENSELY! You do NOT want to experience that kind of pain, ever.
There is NEVER such a thing as a "minor" fracture. Even a small "stress fracture" that can happen to runners can cause significant pain and disability.
If you are trying to break your own bone (in any area of your body), purposely, in order to harm yourself...
WikiAnswers does NOT give advice on how to harm your body. PLEASE do not try to break any bone in your body. Injuring yourself on purpose will NOT get you the outcome you think or hope it will. Instead, there will be increased medical bills/costs, possible hospitalization and/or surgery to fix the bone, possible infection from the fracture or from the surgery, possibly the need for IV antibiotics, possible lifelong pain and/or disability... or even death as a result of the injury.
If you feel the need to hurt yourself, you need someone to talk to in your area. People are available 24/7 to listen and help you. You can call your local Hot Line or call 1-800-273-TALK if you live in the US (for more numbers and support in different countries click on the link below).
What are the skeletal systems major functions?
The skeletal system provides support and shape to the body, protects internal organs, allows movement through attachment to muscles, produces blood cells in the bone marrow, and stores minerals such as calcium and phosphorus for the body's use.
