Long Distance Signaling Nervous vs. Endocrine
Nervous System
Endocrine System
Speed
Fast
Slow
Duration
Very Short
Can be long-lasting
Specificity
Location of synapse
2nd messenger cell
signaling
Types of nervous system cells
o Sensory Neuros
Carries information from a stimulus to another neuron
Such as smell, light, pain
o Motor Neurons
From a neuron to muscle, endocrine cell or cardiac conducting system cell
o Interneuron
One neuron to another
o Other supporting cells called glial cells
You have ten times more glial cells then neurons
o Differences in nervous systems due to different arrangements neurons
o Neurons are arranged in a circuit
Sensory neuron picks up sensory information, propagates action potential,
passed information to interneurons, then to motor neurons
Neutral Circuits squid giant synapse

o I sensory neuron fires an action potential after sensing prey
o II interneuron receive the signal, and passed on to the motor neuron
o III motor neuron receives the signal and contracts to propel the squid
Neural Circuit patellar tendon reflex

Organization of Animal Body
o Radical Symmetry more then 1 axis of symmetry such as star
o Bilateral Symmetry 1 axis of symmetry, such as our body
o Anterior head end
o Posterior tail end
o Dorsal back
o Ventral front
o Medial near the axis line
o Lateral away from the axis line
