Should you wrap an ace bandage around a fractured metatarsal bone?
A broken foot needs to be wrapped or splinted until you are able to get to the doctor and get it X-Rayed. If it is truly broken, it will need to be put in a cast for a while. For additional First Aid tips, visit Answers.com
What is the function of the cap and tail on eukaryotic mRNA?
The cap and tail on eukaryotic mRNA play important roles in mRNA stability and translation. The 5' cap protects the mRNA from degradation and helps in the initiation of translation. The poly(A) tail at the 3' end of mRNA also plays a role in mRNA stability and regulation of translation.
What part of the hip bone is most anterior?
The Pubis is the most anterior part of the hip bone, or the pubic bone as it should be called
What do bones form when they come together?
When bones come together, they form joints. Joints are connections between two or more bones that allow for movement and provide structural support to the body. There are different types of joints, such as pivot, hinge, ball and socket, and gliding joints.
How does you skull protect your brain when hit in the head?
The cranium forms a shell-like shape around your brain to protect it from falls and summer-saults.
The cranium makes a shield to your brain by stopping falls and hits to your head. This shell like shape is very hard and is very hard to break or crack, that is why it protects your brain.
What are the layers that make up your bones?
Bones are composed of multiple layers, including the periosteum (outer layer), compact bone (dense, strong layer), spongy bone (porous inner layer), and bone marrow (innermost layer where blood cells are produced). These layers work together to provide structure, support, and protection to the body.
What bone makes the posterior point of the elbow and what is the name of that projection?
The bone that makes the posterior point of the elbow is the ulna. The projection at the posterior point of the elbow is called the olecranon process.
How many bone in vertical column?
There are 33 vertebrae in the human spinal column: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal vertebrae. These bones are stacked on top of each other to form the spine.
Is a Tail Bone the same as a Butt Knuckle?
As I learnt from urbandictionary.com, a butt nuckle is as follows:
(noun) The popping sound made by an explosive fart. A crisp and short passage of gas from ones butt.
Hope this helped :P
What three bones meet at the shoulder?
The upper arm bone (humerus), the collarbone (clavicle), and the shoulder blade (scapula) meet at the shoulder joint.
How can you tell if a rib is right or left?
I remember by identifying the head as the part that connects to a vertebra, then make sure that the coastal groove is down. I am then able to identify if it is the right or left. Hope that helps...
What bones are roughly cubed shaped?
In humans there is a bone named the 'cuboid' , it is the 'heel' bone in the foot.
What is the weakest part of the femur?
The weakest bone in your body would be the spine or spinal cord. or your nose
Add 2.
You probably mean weakest because of its sheer smallness. Or maybe you mean weakest because it's made of something weaker. The bones within the ear are probably the weakest because they are the smallest and you could break them very easily between your fingers. Re the answer above, I doubt if the spine is the weakest and the spinal cord is not a bone anyway. You might break your spine, but that would probably be because one vertebra has come away from another vertebra, not because the bone has broken.
add 3. Possibly the Hyoid bone in the throat is among the weaker, as it may be broken just by finger or thumb pressure. But as in A2, the Stapes in the ear is very delicate, but very well protected. Both of these bone (groups) are disconnected from other bones of the body.
Which bone or bones make up the cheekbones?
The zygomatic arch is the bone name for the cheekbone. The arch is made up of the zygomatic process of the temporal bone and the temporal process of the zygomatic bone.
What tissue forms supporting rings of respiratory passages?
Ciliated and pseudostratified columnar epithelial cells plus goblet cells for the secretion of mucin.
How many bones in a newly born infant?
I believe 380 or 308 but! They are mostly made of cartilage as they grow the cartilage hardens and turns into bones also the number decreases thus having 206 bones in a average body. Also when you are a new born the skull is open and then fuses togehter that explains the squiggly lines on your skull...
Is the spine projection or depression?
A meatus is an opening; therefor, it's a depression, not a projection.
What are the round bones of the body?
The round bones of the body include the patella (kneecap) and the talus (ankle bone). These bones are classified as round due to their circular or oval shape.
What bone cells in the body remodel the synthetic material and produce new bone?
Osteoclasts are the bone cells responsible for breaking down and resorbing old bone tissue. Osteoblasts, on the other hand, are responsible for producing new bone tissue and laying down the synthetic material. Both cell types work together in a process known as bone remodeling.
What is an avulsion lateral malleolus?
the lateral malleolus is the bony prominence on the outside of your ankle. it is commonly referred to as the ankle. an avulsion to this structure is when part of it is forceably broken away from the maleolus.
What are the two locations on a thoracic vertebra where the ribs articulate?
The two locations on a thoracic vertebra where the ribs articulate are the costal facets on the sides of the vertebral body and the transverse costal facets on the transverse processes. These articulations form the joints that connect the ribs to the thoracic vertebrae.
Why does the skull have joints?
The sutures of the skull have several important roles. In development they are straight edged and lie on top of a network of soft cartilage and connective tissue to allow the head of the newborn to deform in order to fit through the narrow birth canal.
In adult life the main function of sutures is to distribute impact force evenly around the skull. The collagen present in the interfacial layer coupled with the jagged interlocking distribute impact force evenly across the entire length of the sutures and connecting bone. They are around 5 times stronger under impact than pure bone and as the collagen content goes up with increased interdigitation they can be stronger.
Under slow compression only extremely interdigitated suture can match the strength of pure cranial bone.

Is epithelium tissue found in bones cartilage and fat?
Look through her and you will find that this tissue is found in those places and many more. Depends on what type of epthelial tissue:
Types of epithelial tissue - (type - structure - location - function)
- Simple squamous - one layer of fat cells - lines ventral body cavities, heart and blood vessels, and portions of the kidney tubules (thin sections of loop of Henle), inner lining of the cornea, and exchange surfaces of the lungs (alveoli) - permits difusion of gases, reduces friction, controls vessel permeability, and performs absorption and secretion
- Simple cuboidal - one layer of cube-shaped cells - found in glands, ducts, portions of kidney tubules - provides limited protection, secretion of hormones, and / or absorption
- Simple columnar - one layer of column-shaped cells - line the stomach, intestine, gallbladder, uterine tubes, and collecting ducts of kidneys - protection, secretion of gastric juices and enzymes, and absorption of digestive end products (if microvilli present)
- Pseudostratified columnar - line the nasal cavity, bronchi, and trachea - provides protection and secretion
- Ciliated - one layer of columnar cells with cilia on their free surfaces - lines trachea and fallopian tubes - sweeps mucus and dust to the pharynx and sweeps ovum toward uterus.
- Transitional - many layers of cells, but surface cells change from rounded to flat - line the urinary bladder, renal pelvis, and ureters - permits expansion and recoils after stretching
- Stratified squamous - many layers of cells (surface -- flat, lower cells -- rounded, lower layer undergoes mitosis) - located on the skin surface and line the mouth, throat, esophagus, rectum, anus, and vagina - provides physical protection against abrasion, pathogens, and chemical attack. Surface cells of epidermis are dead providing a barrier to pathogens while interior cells are living and also provide a barrier for pathogens.
What bones are inferior to your pelvis?
Tracing down the spine the pelvis leads to the coccyx, aka the tailbone, though the femurs of your legs also extend past the bottom of your pelvis.
The pelvis itself is made of the sacrum (back) and os coxa (sides) (and some people include the coccyx.)
