Chemistry of Life
This element forms the backbone of all organic molecules and can form four covalent bonds.
Carbon
This is the control center of the cell that contains the genetic material (DNA).
Nulceus
This is the most common fixed cell in connective tissue; it secretes protein fibers.
Fibroblast
This muscle type is voluntary, striated, and attached to bones.
Skeletal Muscle Tissue
These are the mature bone cells that reside in lacunae.
Osteocytes
These are the monomers (building blocks) of proteins.
Amino acids
These small organelles are the site of protein synthesis.
Ribosomes
These thick fibers have high tensile strength and are abundant in tendons and ligaments.
Collagen Fibers
This is the only muscle tissue that is both striated and involuntary.
Cardiac Mușcle Tissue
This is the most common type of cartilage; it covers the ends of bones and supports the respiratory passages.
Hyaline Cartilage
This type of bond involves the equal sharing of electrons between atoms.
Covalent Bonding
This organelle packages and ships proteins and lipids; it is often called the “post office” of the cell.
Golgi apparatus
This loose connective tissue stores energy, cushions organs, and insulates the body.
Adipose Tissue
This muscle tissue is involuntary, lacks striations, and is found in the walls of hollow organs.
Smooth Muscle Tissue
These cylindrical structural units of compact bone contain a central canal surrounded by concentric lamellae
Osteons
These macromolecules are hydrophobic, include fats and steroids, and make up a major part of cell membranes.
Lipids
This organelle contains digestive enzymes and breaks down worn-out cell parts and foreign material
Lysosomes
This specialized connective tissue has cells living in lacunae, a gel-like matrix, and no direct blood supply
Cartilage
Skeletal muscle fibers are long, cylindrical, and contain many of these.
Nuclei
This is the liquid matrix of blood in which the formed elements are suspended.
Plasma
This property of water allows it to absorb and release large amounts of heat with little change in its own temperature, helping stabilize body temperature.
High Specific Heat Capacity
This membrane system has ribosomes attached and is the site of protein synthesis and modification.
Rough Endoplasmic Reticulum
These wandering cells perform phagocytosis and defend against infection
Macrophages
These specialized junctions allow electrical impulses to travel rapidly between cardiac muscle cells.
Intercalated Discs
This tough cartilage is an excellent shock absorber and is found in intervertebral discs and the knee.
