Neuron: Pyramidal cell -Dendritic spines: the little “thorns” on the creepy ominous neuron tree which are points of synaptic contact b/w neurons -Neuronal cell body of pyramidal cell: looks triangular -FYI: axons don’t have spines, but dendrites do
Neuron: Pyramidal cell -Dendritic spines (D) -Axon (A) -You can distinguish between them because axons don’t have spines, but dendrites do *from demo on blackboard sites of synaptic contact with other neighboring neurons
Neuron: Pyramidal cell -Cell soma of pyramidal cell (1) -Apical dendrite (2) -Basal dendrite (3) -Initial portion of axon (4) -Cell soma of neuron in the striatum(5) -Dendrite with spines (6) *from demo on blackboard
Terminal Boutons -(Black arrows) -Terminal Boutons are the terminal knobs that synapse w/ other cells, while Boutons en Passant (buttons in passing) are found along the dendrites. *from demo on blackboard

Smooth Muscle! Oh hey Harry Potter Nuclei! Harry Potter nuclei and b/c smooth muscle is always in arteries (aka this thick walled, alien squiggle beast with a lumen full of RBCs)
Skeletal Muscle (Lines o’ nuclei, long, multinucleated cells, peripherally located nuclei)
Node of that French Guy (Ranvier) Space between the sausage links!
Skeletal Muscle (STRIATED, lines o’ nuclei, long, multinucleated cells, peripherally located nuclei)
Cardiac Muscle Centrally located nuclei in cross section!
Skeletal Muscle! (peripherally located nuclei)
Name the small dark features on the dendrites. Be Specific.
Dense regular connective tissue (tendon) Shiny and wavy with THIN nuclei all over the place
Motor end plate ...because plunger
