Motor function
Responding to integration decisions.
Cells and organs contacted by motor neurons in cranial and spinal nerves.
Central nervous system (CNS)
Brain and spinal cord: Thoughts, memories and emotions.

Transfer RNA - carries amino acids into ribosomes and bonds with mRNA for protein production.
Integral protein
Permanently attached to the biological membrane.
Selective permeability
will allow certain  molecules or ions in via diffusion or facilitated diffusion.
Active transport
Based on sizeRequires ATPGoes against concentration gradient
