BMS 1052 - test 1 cheatsheet

Description

BMS1052 Notes – Weeks 1–3 (Neuroscience) These notes cover all key learning objectives from Weeks 1–3 of BMS1052 in clear, structured detail, making them perfect for MCQ revision and short-answer preparation. What’s Included Neurons: structure of prototypical neurons, soma/organelles, cytoskeleton, axons and dendrites, neuron classification. Glial Cells: oligodendrocytes, Schwann cells, astrocytes, microglia, and ependymal cells – roles and locations. Nervous System Organisation: CNS vs PNS, somatic vs autonomic (sympathetic and parasympathetic), spinal cord structure and function. Ion Movement & Membrane Potentials: concentration gradients, Nernst and Goldman equations, ionic equilibrium vs membrane potential, Na⁺/K⁺-ATPase pump. Action Potentials: channel selectivity and gating, phases of AP, refractory periods, stochastic nature of channel activity, conduction speed (myelin, axon diameter, node spacing, temperature). Synapses: structure and function of electrical vs chemical synapses, neurotransmitter release mechanisms, receptor types (ionotropic vs metabotropic), EPSPs vs IPSPs, neurotransmitter removal methods. Integration: factors determining EPSP size, spatial vs temporal summation (length constant λ, time constant τ), Cl⁻ mediated inhibition, modulation of vesicle release probability. Features Concise but detailed exam-ready explanations written in full sentences. Tables and diagrams included for quick comparison and visual learning. Colour-coded action potential graphs showing AP phases and refractory periods. Clear summary points for each learning objective to match assessment style.
