matrix
Short answer- the chondrocytes are embedded in the matrix because matrix is what these cells produce, and there's no where else for it to go! So, basically, you've got it backwards, chondrocytes can be as smooshy and forgiving as a skin cell, so they don't need protection; they're there to provide protection in the form of cartilage to other organs or surfaces. Longer answer- Cartilage is composed of cells (chondrocytes) that live in little spaces (lacuna, lacunae for plural). These cells are the ones that create the matrix, which is further composed of collagen fibers, ground substance (proteoglycans mostly) and elastic fibers. The proportions of the above result in different characteristics of the material- more elastic fibers and fewer collagen fibers result in bendy cartilage, like you find in your nose and ears. Lots of collagen and proteoglycans results in harder tissue, as you would find in your windpipe (trachea) and between joints of your bones. Interestingly, cartilage is one of the few "avascular" tissues (no blood vessels) in the body- it survives by absorbing oxygen and excreting waste by diffusion through the matrix. This is one of the reasons it's so slow to heal, so take care of those sprained ankles!
Matrix is the fine grained material in which larger crystals or clasts are embedded in rock of all types, whereas cement is precipitated mineral from fluids which binds large and small rock particles together in sedimentary rock.
They are located below the epidermis.they are thin walled living cells thickened at the corners with very little inter-cellular spaces.
There is no certain city but it is located in the wide open spaces of South Central Texas.
chloroplasts can be located in many places in a leaf.. guard cells,spongy mesophyll, palisade mesophyll, Palisade mesophyll contains the most amount of chloroplasts.... because that is where the energy from the sun is trapped, therefore the plant needs to have many chloroplasts in order to capture the light energy.. extra* the palisade cells are long and wide in order to increase the surface area of contact with the sun.. there are many air spaces between the spongy mesophyll for gas exchange..
Chondrocytes or cartilage cells are the only cell in the cartilage matrix.
which one is correct: a. are mature cartilage cells located in spaces called lacunae b. within the cartilage divide and secrete new matrix c. located deep to the perichondrium d. never lose their ability to divide I like the right answer is b!!
The cells are open spaces containing air that are located throughout the mastoid bone.
the bones are filled with bone marrow

The nonliving material surrounding cells is called the intercellular matrix. The matrix fills the spaces that are between the cells.
the extracellular matrix. It contains a gel-like ground substance and protein fibers. connective tissues have a lot of extracellular matrix compared to epithelial tissues that have very little.
cartilage because i am the smart one and you aren't
Connective tissue is found throughout the body and includes fat, cartilage, bone, and blood. The main functions of the different types of connective tissue include providing support, filling in spaces between organs, protecting organs, and aiding in the transport of materials around the body.

No, rats have more bone than cartilage, same as most mammals. However, their skeleton has more flexibility at the joints, particularly the pectoral girdle and rib cage, which allows them to bend and squeeze into spaces that do not look big enough for a rat.
