What does spongy bone lack that compact bone has?
Spongy bone has holes in it that make it strong, but compact bone doesn't have any holes in it.
What does spongy bone tissue lack?
Spongy bone tissue lacks Haversian canals, which are found in compact bone tissue. These canals are responsible for carrying blood vessels and nerves through the bone. Spongy bone also lacks a dense arrangement of bone cells, giving it a more porous and lightweight structure.
Disadvantage of compact bone?
One disadvantage of compact bone is that it is dense and heavy, making it more prone to fractures under excessive force or impact. Additionally, its lack of porosity may limit its ability to store essential minerals and blood cells compared to spongy bone.
Why does the cacti lack a spongy layer?
Cacti lack a spongy layer in their stems because they have adapted to hot, dry environments with limited water availability. The absence of a spongy layer reduces the surface area for water loss through transpiration, helping cacti conserve water and survive in arid conditions.
How would homeostasis be affected if bones were only made of spongy tissue?
If bones were solely composed of spongy tissue, homeostasis would be compromised due to the lack of structural integrity and strength that compact bone provides. Spongy bone is lighter and less dense, which could lead to increased susceptibility to fractures and instability in the skeletal system. This instability would affect the body's ability to support itself and protect vital organs, ultimately disrupting the maintenance of internal conditions such as mineral balance and blood cell production. Overall, the skeletal system's role in homeostasis would be significantly impaired.
What is the difference between Scurvy and Rickets?
Scurvy is caused by a lack of vitamin C in the body, symptoms typically include lethargy, spongy gums, bleeding from mucous membranes and spots mainly on the legs and thighs. Rickets is caused by a lack of vitamin D, calcium, phosphorus or magnesium in the bones of children. This causes bone softening leading to fractures and deformity.
