Cards

Term
Integration
Definition

Adding and combining signals to form one big one

-Spacial summation and temporal summation (time)

Term
Conduction faster in axons with..
Definition

Wider and myelinated

-conduction in interneurons usually passive and decremental

Term
Dendrites and APs (3)
Definition

-been found to actively conduct APs away from site of generation in either direction

- Dendritic spines change very rapidly to neural stimulation

-Dendritic spines compartmentalize denderite - keep postsynaptic chemical changes restricted to immediate area in synapse

Term
Advantage of presynaptic inhibition and facilitation
Definition
-Selectively influence single synapses, rather than entire neuron
Term
Heteroreceptors
Definition

-Usually responding to diff receptors but when other axon coming into play, will respond to those signals as well.

-axoaxonal contact: presynaptic inhibition and facilitation

Term
Nondirected synapses
Definition

-Site of release at some distance from site of reception

-Varicosities along axon and widely dispersed to surrounding targets

-string-of-beads

Term
Diff of small and big NTs production
Definition

-small: made in cytoplasm of terminal button, packaged into vesicles by golgi complex

-Big: Created by ribosomes in cytoplasm of cell body ->packaged into vesicles by golgi complex and transported microtubules

Term
Coexistence
Definition
-Many neurons contain 2 NT's
Term
2 adv of gap junctions
Definition

1. Allow small molecules to pass through passively, very fast comm

2. Permit comm in either direction

Term
noradrenergic/adrenergic
Definition
-realease NE, release E
