Cell parts: Neuron

Question 1

SOMA

Answer 1

-Central part
-Has all the cell organelles+Rough ER-produces proteins
-20μm

Question 2

CYTOSKELETON

Answer 2

Made up of:
-Microtubules: MAP associated proteins Tau stabilize and important for Alzheimer’s
- Neurofillaments: support for axonal growth
-Microfilaments: associated with membranes

Question 3

AXON

Answer 3

Has little to no ribosomes only related to ptchanges
Made up of:
-Hillock: Forms Spike Initiation Zones, connects to the SOMA
- Collaterals: branching of axon
-Boutons/axon terminals: synapses with dendrites and cell bodies
Synapse: Pre+ Post part

Question 4

DENDRITES

Answer 4

• ANTENNA of the neruon, receives info
  -Tons of synapses
  -Shape of spines is dynamic: different shape+different strength
• RIBOSOMES for local protein synthesis, eg. memory
