Cellular homeostasis involves maintaining a balance of several factors that make a cell healthy. The cell membrane is a lipid bilayer that prevents that passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell.
Dendrite; axon; synapse
These are parts of the neuron which is considered as the basic unit of nervous system. The cell responsible for receiving sensory input from the external environment. The stimulus will be transported in an electrical signal via neuronal parts. Axon transmit signal to the other neuron. Dendrites are the receiving part of the neuron. Synapse is the space between each neuron where elctrical impulse is converted into a chemical signal via neurotransmitters.
