Plasmodesmata
The channel between animal cells is called a gap junction. Gap junctions allow for the direct exchange of ions and small molecules between adjacent cells, facilitating communication and coordination within tissues.
A junction between two bones is called a joint. Joints allow for movement and flexibility within the skeletal system.
Gap junctions allow neighboring cells to exchange small molecules, ions, and electrical signals directly through channels formed by connexin proteins. This enables rapid communication and coordination between cells in tissues such as cardiac muscle and nervous tissue.
A gap junction is a '' tunnel '' between cells in which messages and nutrients can be passed back and forth. A tight junction is the connection between two cells that is strongly '' sown '' with protein threads to help maintain tissue conformation.
A slit junction is a type of cell-cell junction found in epithelial tissues where cells are joined by narrow, elongated gaps or slits. These junctions allow for selective permeability and regulate the passage of molecules between cells. They are important for maintaining tissue integrity and barrier function.

Tight junction - impermeable junction that encircles the cell Desmosome - anchoring junction scattered along the sides of cells Gap junction - a nexus that allows chemical substances to pass between cells

A joint that does not allow any movement is called a synarthrosis joint. This type of joint can be found in the skull, where two bones have a suture line that is immovable. An example is the joint between the two parietal bones of the skull.
The nuclear envelope is a double membrane structure that surrounds the nucleus of a cell. It acts as a barrier between the nucleus and the cytoplasm, regulating the passage of molecules in and out of the nucleus. It also contains nuclear pores that allow for the movement of specific molecules.
Nuclear pores are large protein complexes that regulate the passage of molecules into and out of the cell's nucleus. They control the movement of molecules such as proteins, RNA, and other signaling molecules based on their size and specific signals.
Molecules react to thermal energy, or heat, as well as pressure. When you increase the temperature of molecules, they will increase their vibration and movement. Pressure can also allow molecules to move from one area to another.
