HMB201H1 Lecture Notes - Cephalization, Membrane Potential, Net.
Document Summary
Endocrine + nervous systems regulate [balance] animal physio [their body] Neural communication = how the neurons are connected to each other + they send signals. Membrane potential = how na goes in and k comes out and they fix those chemical gradients. Cells of the nervous system are called: neurons aka excitable cells. The reason for the name excitable cells is because they send information when they are happy and excited [turned on] The excitable cells [neurons] they send chemical + electrical signals back + fourth. We have a nervous system with two methods of input [afferent] + output [efferent] In between both those methods, we have an integrating centre [the bridge] for the neuron to pass through from input to output. Integrating centre is the brain which is in the cns. The cns has a cluster of nerves together. Input + output mnethods are in the pns [anything outside of the brain + spinal cord].
