Nervous Coordination and Sense Organs concept study for CBSE Biology examinations. The nerve cell or neuron consists of a cell body with one or more elongated projections extending from it. The cell body contains the nucleus. The projections are part of the cytoplasm and are called axons if they are long and singular, or dendrites if they are short and branched. Nerve endings or receptors at one end carry the sensors that respond to the stimuli, while on the opposite side, the stimulus is transferred ultimately to the brain. The sensory organs receive the various stimuli from the bird’s environment.
