What is another name for the medullary cavity of the bone?
Another name for the medullary cavity of the bone is the marrow cavity.
What is the function of the medullary cavity?
The medullary cavity is the central cavity of bone shafts. This is where red and yellow bone marrow are stored. The medullary cavity is also involved in the formation of red and white blood cells.
Do osteoblasts from the medullary cavity migrate to the fracture site?
Yes, osteoblasts from the medullary cavity can migrate to the fracture site to participate in bone healing. When a bone fractures, osteoblasts are recruited from various sources, including the medullary cavity, to produce new bone tissue and facilitate the repair process.
Medullary cavity function?
The medullary cavity is a space within the diaphysis (shaft) of a long bone. It contains yellow bone marrow, which stores fats and serves as an energy reserve. Additionally, the medullary cavity provides space for blood vessels and nerves to pass through the bone.
Which Nephrons have a long loop of Henle?
Juxtamedullary nephrons have a long loop of Henle, which extends deep into the medulla of the kidney. These nephrons play a crucial role in concentrating urine by creating a hypertonic medullary interstitium through the countercurrent multiplier mechanism.
What does the mechanism of the medullary pressure of the osmotic gradient depend on?
The mechanism of the medullary pressure of the osmotic gradient depends on the differential permeability of the ascending and descending limbs of the loop of Henle to solutes like sodium and urea. This causes the accumulation of solutes in the medulla, creating an osmotic gradient that facilitates water reabsorption.
What establishes the medullary osmotic gradient?
The loop of Henle is primarily responsible for establishing the medullary osmotic gradient in the kidney. This gradient is maintained by the countercurrent mechanism, where solute concentration increases towards the renal medulla, allowing for water reabsorption by osmosis. The loop of Henle actively transports sodium and solutes to create this gradient, essential for urine concentration and water conservation.
What rhymes with medullary?
There are no perfect rhymes for the word medullary.
What membrane lines lines the medullary cavity?
The endosteum lines the medullary cavity.
List five different effects produced by these medullary hormones?
what are the medullary hormones You can't answer a question with a question...the medullary hormones (adrenal) they are referring to are epinephrine and norepinephrine.
How can we use the diameter to calculate the medullary index?
The medullary index is calculated by comparing the diameter of the medullary cavity to the diameter of the entire bone. To find the medullary index, you divide the diameter of the medullary cavity by the total diameter of the bone and then multiply the result by 100 to express it as a percentage. This index helps assess the relative size of the medullary cavity in relation to the overall bone structure, which can be useful in fields like anthropology and forensic science.
What is another name for the medullary cavity of the bone?
Another name for the medullary cavity of the bone is the marrow cavity.
What is medullary?
Medullary (myelin)- sheath is the covering of nerve fibres. It insulates the nerve fibre (axon) and prevents leakage of ions.
Meaning of medullary?
The word medullary refers to a part of the body or an organ that resembles bone marrow, such as dorsally located tissue.
Which medullary index indicates an animal hair?
The medullary index is a measurement used to differentiate between types of hair. In animal hair, the medullary index is typically greater than 0.5, indicating a wider medulla relative to the diameter of the hair shaft. In contrast, human hair usually has a medullary index of less than 0.33. Therefore, a medullary index greater than 0.5 suggests the hair is from an animal.
Does bone have a medullary cavity?
true
What function medullary rays play in trees?
The medullary rays transport substances from the xylem and phloem to the inner and outer parts of the stem.
