1. Which of the following are morphological classifications for neurons? (be careful with question like these I got this one wrong once because I didn’t understand the difference in “classification and type” of neurons) a. Astrocyte – is a type of cell b. Monopolar/Unipolar - One axon and no dendrite ( sensory, Dorsal Root Ganglia, Cranial Nerve Ganglia) c. Multipolar - one axon and many dendrites (motor or integrating; ventral horn in spine) Pseudounipolar – one axon and no dendrite (sensory, DRG, CNG) Bipolar – one axon and one dendrite (sensory, eye, olfactory epthelium) always will have one axon but dendrites can vary in number* d. Dipolar – this was almost a trick question but the spelling was off e. Sensory – 2. The specific region of a neuron where an action potential is initiated is the Axon Hillocks . Postsynaptic Terminal : place were receptors are held to receive NT (does not have be located on dentrite) Dendrite : receives impulses Soma (body): cell body Axon Hillock : where action potential is produced Axon : carrier of the action potential Myelin Sheath : helps to propagate (transmit) action potential quickly Neurolemma: outmost layer of myelin sheath Node of Ravier : small patches on an axon that lacks myelin sheath and has high density of Na/K channels Saltatory Conduction: action potential jump from node to node Presynaptic Terminal : axon terminal and place were neurotransmitters (NT) are stored and released Synapse (Synaptic cleft) : site of communication of two neurons/ space between 3. Which of the following men would fondle the bumps on your head if he wanted to get to know you better? a. Albertus Magnus b.

Plato : believes brain is seat of mental process Aristo : tlebelieves heart is seat of mental process Herophilus ("Father of Anatomy"); believes ventricles are seat of human intelligence.

a. Carriers input from the outside world into the nervous system – I do believe this is a nerve ending b. Carries info between the internal organs/glands and the nervous system – if you think about this there is really nothing in between nerves and what they are innervating. c. Carries info between different neurons
