2 major cell types in the brain Ans: Neurons -> process info, sense environmental changes and communicate changes. Glial cells - > insulate, support and nourish neurons. 4 parts of neuron Ans: Dendrite, cell body, axon, axon terminal Neurons Ans: Movement = input zone: dendrite -> trigger zone: axon hillock -> conducting zone: axon -> output zone of axon terminal Neuron structure and function Ans: have dendrites -> highly branched extensions that receive signals. axo...

NSC WRITTEN EXAM QUESTIONS. relative refractory period - CORRECT ANSWER period following absolute refractory period, more difficult for the neuron to fire a second AP since membrane is further below threshold (hyperpolarized); more stimulation required Neuron Doctrine (Ramon y Cajal) - CORRECT ANSWER Neurons are discrete, functional units that communicate by contact, not continuity Reticular Theory (Golgi) - CORRECT ANSWER Neurons fuse to form a CONNECTED network/reticulum, making bra...

Cytoskeleton Correct Answer bones and muscle of the cell Gives shape and allows the cell to move What is the cytoskeleton composed of? Correct Answer actin and microfilaments Intermediate filaments Correct Answer thicc and solid Toughest and most durable Where are intermediate filaments located? Correct Answer around the nucleus and extend to the periphery It is anchored to the plasma membrane What is the structure of intermediate filaments like? Correct Answer alpha helices and...

Nissl Stain (what does it stain?) stains the Nissl bodies, also known as the rough endoplasmic reticulum. Nissl Stain (what does it show us?) - distinguishes neurons and glia from one another. - can be used to identify shape and size of the cell soma (body), not the processes (axons and dendrites). (the simple stain shows the organization of the spinal cord) Brainpower 0:00 / 0:00 Nissl Stain (what does is facilitate the study of?) facilitates the study of cytoarchitecture ...
