The answer is D. Treatments decrease pain temporarily and must be repeated
Answer:
The most correct answer is: It varies in consistency based on the amount of protein fibers and fluid
Explanation:
The extracellular matrix (ECM) is the environment surrounding cells, which is normally composed by fibers (i. e.: collagen, elastin, etc...), soluble proteins and other macromolecules (such as hyaluronic acid) embedded in fluid. The relative concentration and composition of those components conditions, among other things, the physical consistency of the ECM.
- No blood vessel arises from ECM; they derive from specific precursor cells. Additionally, cartilage is an avascular (has no blood vessel) type of connective tissue.
- ECM does provide oxygen and nutrients to diverse tissue, including bone, however bone tissue <em>does</em> have blood vessels.
- Neuronogenesis (generation of new neurons) takes place within the developing nervous system, with neuronal precursor cells being thoroughly surrounded by other cells such as radial glia. Typically, neighboring ECM has a minor or negligible role in this process.
Answer: Blister
Explanation:
A blister is a fluid filled bubble like structure which develops in the uppermost layer of the skin that is epidermis. It may also form within the epidermis and dermis.
It develops due to friction, infection, freezing, burning, burns and contact with chemicals. Blister can also be caused due to diseases.
It can be filled with blood, plasma, serum and pus.
Answer: Broca's area
Explanation:
Broca's area is primarily responsible for producing speech. It controls motor functions involved with speech production. It is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain.
People who have damage to this area of the brain can understand words but struggle to put them together in speech. Tony clearly has no problem processing what is being said but because of the damage he can't put his thoughts to words.
