Structure of neuron — Study Path Agent

Chapter 1

Neuron overview & types (what a neuron is, common classes)

1

Neuron polarity: input → integration → output

2

Functional classes: sensory, motor, interneuron

3

Morphological classes: multipolar, bipolar, pseudounipolar

4

Key neuron terms to label on a diagram (soma, dendrite, axon hillock, axon, terminals)

Chapter 2

Cell body (soma) & nucleus (core organelles and roles)

5

Soma boundaries: plasma membrane and cytoplasm basics

6

Nucleus & nucleolus (genetic control and ribosome production)

7

Nissl substance / rough ER (protein synthesis in neurons)

Chapter 3

Dendrites (input structures and integration)

8

Dendritic branching patterns (arbors) and receptive field concept

9

Summation basics: spatial vs temporal integration (structural relevance)

Chapter 4

Axon (output cable: parts and transport)

10

Axon hillock & initial segment (trigger zone anatomy)

11

Axolemma (axon membrane) and axoplasm (axon interior)

12

Axon collaterals and terminal arborization (output distribution)

Chapter 5

Myelin & nodes of Ranvier (insulation and conduction features)

13

Myelin anatomy: internodes and wrapping of glial membrane

1 subtopics

14

Glial sources of myelin: Schwann cells (PNS) vs oligodendrocytes (CNS)

15

Nodes of Ranvier and saltatory conduction (structure-function link)

16

Myelinated vs unmyelinated fibers (structural differences)

Chapter 6

Synapse (connection to other cells)

17

Synapse anatomy: presynaptic terminal, synaptic cleft, postsynaptic membrane

18

Synaptic vesicles and active zones (where release occurs)

19

Neurotransmitter receptors: ionotropic vs metabotropic (where they sit)

20

Types of synapses by location: axodendritic, axosomatic, axoaxonic

21

Electrical vs chemical synapses (structural hallmarks)
