This information is received through receptors inside or at the surface of the body. It is then processed by one of a number of complex systems of neurons and pathways, depending on what information has been received.
Uncover the intriguing aspects of somatosensation in the peripheral nervous system. Discover the five key senses: position sense, vibration sense, touch, pain, and temperature. Learn about the unique roles of mechanoreceptors, nociceptors, and thermoreceptors, and their vital part in sending sensory information to our brain.
Mar 27, 2014 · Explore the neuron resting membrane potential, a stable charge separation across the cell membrane. Discover the roles of anions and cations, and how their concentration differences create this potential. Uncover how neurons use these electrochemical driving forces to perform their functions.
Neurons (or nerve cells) are specialized cells that transmit and receive electrical signals in the body. Neurons are composed of three main parts: dendrites, a cell body, and an axon.
Anatomy of a neuron. Overview of neuron structure and function. The membrane potential. Electrotonic and action potentials. Saltatory conduction in neurons. Neuronal synapses (chemical) The synapse. Neurotransmitters and receptors. Q & A: Neuron depolarization, hyperpolarization, and action potentials.
