Bone resorption is a process whereby bone matrix is ____________ by substances released by ____________ . The lysosomes inside o
Nikitich [7]

Answer:

a. destroyed

b. osteoclasts

c. proteolytic enzymes

d. hydrochloric acid

e. blood

f. low

Explanation:

Resorption is the loss of substance from any mineralized tissue, mediated by cellular and humoral systems of their own. The four mineralized tissues of our economy, bone, cement, dentin (mineralized fraction of the dentino-pulp functional complex) and enamel, offer different degrees of resistance to resorption. The bone has the greatest lability and the enamel the least. The fact that the bone tissue is the least resistant to resorption is used to move and reposition teeth by controlled forces (orthodontics); and the fact that the enamel is the most resistant has led to think that it does not suffer from resorption.

Osteoclasts They are the spring cells par excellence; they belong to the lineage of the monocitomacrophages. They are large, multinucleated mobile cells, with a clear area and a rough brush border that live for about two weeks and disappear by apoptosis (cell death programmed by fragmentation in membrane particles that allows their phagocytosis without inflammation). They are responsible for the destruction of the organic and inorganic parts of the mineralized bone fraction. They are active both in the processes of the physiological renewal of the bone and in those of its pathological loss.

Describe what messages are sent by the nervous system when you go outside wearing a sweater on a very hot day.​
mr_godi [17]

Answer and Explanation:

In homeostatic control processes any deviation from the norm sets into motion the appropriate corrective mechanisms which restore the norm. This rectification occurs through negative feedback. When you go outside wearing a sweater on a hot day, the body sends messages to the CNS and the following occurs:

  • The superficial blood vessels vasodilate so that more blood flows near the surface. This encourages heat loss.
  • Sweating and panting. Sweat secreted by the sweat glands evaporate from the surface of the body as it absorbs latent heat.
  • The metabolic rate falls so that the body generates less heat. You also become less active
  • Behavioural response by seeking cooler areas, cold drinks or removal of the sweater.
