Document Summary

Mechanisms that carry information to the cortex for perception and of the motor mechanisms which produce movements we know a lot. Integration of information: arrival of sensory information and the execution of movement. Voluntary movement (mechanism not well known and not simple) Nervous system divided into cns - brain and spinal cord) and pns nerves formed of axons efferent to muscles (somatic) or to the internal organs (autonomic). Pns can also be afferent axons that transmit signal to cns. In presynaptic terminal action potential allow the ca++ voltage- gated channel to be open ca++ enters. Ca++ serves as a second messenger for the release of neurotransmitters into synaptic cleft. Neurotransmitters peptides, amino acids, biogenic amines, and acetylcholine. They bind to postsynaptic receptor of a ligand gated channel. (only found in soma (body) and dendrites). This will create an action potential (inhibitory or excitatory) in the postsynaptic neuron.
