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!
Adipose tissue exhibits a loose connective tissue matrix, mainly composed of a network of collagen fibers, proteoglycans, and glycoproteins. This matrix provides structural support and elasticity to the adipose tissue while allowing for the storage of fat cells (adipocytes) within its spaces.
An osteon is composed of concentric rings of bone matrix called lamellae surrounding a central canal called the Haversian canal. Within the Haversian canal run blood vessels and nerves that supply nutrients to bone cells. Osteocytes, the bone cells, are located in spaces called lacunae between the lamellae.
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.
The spaces between grana in a chloroplast are called stroma. Stroma is where the enzymes for the light-independent reactions of photosynthesis are located.
Chondrocytes are primarily located within the cartilage tissue of the body. They are responsible for maintaining the extracellular matrix of the cartilage and are crucial for cartilage function and health.
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 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.
cartilage because i am the smart one and you aren't
Osteocytes are located in tiny spaces called lacunae. These small cavities are found within the bone matrix and provide a sheltered environment for osteocytes, allowing them to maintain communication with other bone cells through tiny channels called dendritic processes. This network helps regulate bone remodeling and homeostasis.
the stem
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.
Adipose tissue exhibits a loose connective tissue matrix, mainly composed of a network of collagen fibers, proteoglycans, and glycoproteins. This matrix provides structural support and elasticity to the adipose tissue while allowing for the storage of fat cells (adipocytes) within its spaces.
A vacuum is present between inter-molecular spaces.
