Dendrites carry an impulse away from the nerve cell body and are the long extensions of a nerve cell. Nerves pass on impulses with undiminished intensity. The resting potential inside a nerve cell is always positive within the cell. When the threshold level is reached, the sodium channel opens. The size of the action potential is dependent on the strength of the stimulus.
Myelin covers some dendrites.
Receptors for neurotransmitters are located on the posts ynaptic neuron. A centralized nervous system is characteristic of radially symmetrical animals. The c erebellum controls coordination. The thalamus connects the two sides of the cerebrum. The left side of the brain is associated with creativity.
