Neural Activity 1

This text delves into the intricate world of neural activity, focusing on the categorization and anatomy of various neurons. It lists different types of neurons, such as Purkinje, Chandellier, unipolar, bipolar, multipolar, and pyramidal cells, each with distinct roles and structures.

Neural Activity 1

Types of cells

Glia
Radial glia

Guide axon growth over long distances

Oligodendycytes

Form myelin around cells in CNS

Schwann cells

Form myelin around cells in PNS

Microglia

Removes waste material from NS

Astrocytes

Regulates electrical activity of neurons

Interneurons
neuron confined within given structure
Motor neurons
Conducts impulses to muscles
Sensory neurons
Sensitive to stimulation

Anatomy of neurons

Efferent axon
Sends information away from structure
Afferent axon
Brings information into structure
Presynaptic Terminal
Point where axon releases chemicals
Nodes of Ranvier
Interruptions in myelin
Myelin Sheath
Insulating material around axon
Axon
Information sender
Soma
structure containing nucleus
Dendrite
Fibers that receive information from other neuron

Categorising neurons

Pyramidal cells
Chandellier cells
Purkinje cells
Multipolar cells
Bipolar cells
Unipolar cells

Animal Cells

Mitochondria
Perform metabolic activities
Nucleus, ER & Ribosomes
Contains DNA & protein synthesis
Cell Membrane
Seperates inside of cell from outside environment
