Learn about neurotransmitters and their receptors in the human nervous system with Khan Academy.
This article provides an overview of neuron structure and function in the human nervous system.
Bulk transport is a process by which cells move large molecules and particles across the cell membrane.
Just as you wouldn't go to play tennis without your racket and ball, so a cell couldn't translate an mRNA into a protein without two pieces of molecular gear: ribosomes and tRNAs. Ribosomes provide a structure in which translation can take place.
The somatosensory tracts (also referred to as the somatosensory system or somatosensory pathways) process information about somatic sensations such as pain, temperature, touch, position, and vibration. This information is received through receptors inside or at the surface of the body.
G-protein coupled receptors (GPCRs) are a large, diverse group of membrane receptors in eukaryotes that respond to a wide range of external signals. When a ligand binds to a GPCR, it triggers a complex chain of events involving G-proteins and second messengers, influencing various cell functions.
