why doesn't the periosteum cover the articular cartilage of a long bone

Answers

Answer 1
The periosteum doesn't cover the portion of bones that contains articular cartilage, which is the cartilage found in joints that keeps the bones from rubbing together. It is not as tightly packed and contains cells that help in bone growth and repair.
Answer 2

The periosteum does not cover the articular cartilage of a long bone because it is not located in the part of the bone where the joint is formed.

The main function of articular cartilage is to facilitate the movement of a joint in any mechanical circumstance.

The periosteum is a membrane that is part of the constitution of the bones, and that is located throughout the entire bone body, with the exception of the area that is destined for the articular surface.

It is found throughout the central part of the bone, that is, it passes through the entire diaphysis and reaches the metaphysis.

It disappears in the epiphysis because it is the area that generates contact with the tissues that make up the joints, necessary for movement.

Therefore, we can conclude that the periosteum is a membrane that covers all the bones, except the area that is destined for the articular surface.

7. Apply: Look carefully at the picture below and you will see an insect called a
katydid. Katydids evolved from grasshoppers through natural selection. Use
what you have learned to explain how this could have happened.

Answers

Answer: This description is an example of camouflage adaptations.

Explanation:

The grasshoppers are the insects which feed on plant parts and they are able to change their color with respect to their surrounding environment. For example, if they are living on the brown tree trunk they change their color to brown and on the green grass or green leaves they change to green to remain undetected by the predators. This way they are able to camouflage their predators this adaptation allows their survival in their environment with due course of natural selection. The phenotypic trait that is grasshopper is able to change its color increases the chances of survival of the grasshopper. Kaytids have evolved from grasshoppers means they have camouflage traits as that in parent grasshopper species. They have structure which blends with surrounding environment, that is they have wings that mimic that of pattern of leaf venation, also when they change the color to brown the shape of the body appears to be as that of stem. This structural adaptation help them to camouflage their predators.

Nanotechnology is a field of producing materials and devices from atoms and molecules.

Explanation:

Nanotechnology is a field that concerned with producing materials and devices from atoms and molecules. A nanometer is one-billionth of a meter in size. Nanotechnology can be used to “recognize” the cells of interest which allows associated drugs to reach diseased tissue without damaging healthy cells. Nanotechnology produces new and faster kinds of computers, more efficient power sources and more effective medical treatments. Main disadvantages include threats to security, privacy, health and the environment. More research must be done in this field to get more benefits from it.

Which protein is damaged at the nerve endings during mercury toxicity
a. keratin
b. tubulin

Answers

Answer:

b. tubulin

Explanation:

Tubulin is a superfamily of proteins that make up microtubules who have many functions including intracellular trasport of neuron's vescicles

Tubulin protein is damaged at the nerve endings during mercury toxicity.

What do you mean by Mercury Toxicity?

Mercury toxicity occurs when an individual is highly exposed to mercury.

The inhalation of mercury vapor can produce harmful effects on the nervous, digestive and immune systems, lungs, and kidneys, and may be fatal. This is considered as one of the severe toxicity that a person suffers.

Tubulin proteins are a very important class of proteins that helps in the formation of microtubules that have numerous functions in our body including the cytoskeletal arrangement of cells, intracellular transport of neuronal vesicles. And when a person suffers from mercury toxicity, such proteins are damaged and result in improper conduction of nerve impulses.

Therefore, Tubulin protein is damaged at the nerve endings during mercury toxicity.

A. Venous anastomoses ensure that oxygenated blood will get to tissues.
B. The endothelium of both arteries and veins contributes to the prevention of abnormal clotting.
C. The smooth muscle layer of veins is thicker than that of arteries because veins are farther from the heart.
OD. Only veins have valves, which keep the blood moving between heartbeats.
E. The fibrous connective tissue layer of arteries is relatively thin because the blood is moving fast.
OF Arterial anastomoses ensure that blood will be able to return to the heart.

Explanation:

Is this a Med School K Question? The endothelial lining of blood vessels have many functions, including, preventing clotting. Veins carry blood that has very low pressure and have valves to control the one-way flow of blood. The rest are false. Only the pulmonary vein carries oxygenated blood. Arteries have more smooth muscles than veins. The anastomoses are present to act as alternative pathways to reach cells.
