Nervous Tissue Flashcards
What is the function of nervous tissue?
Communication
Input: sensory=
Afferent
Output: motor=
Efferent
What is a non neural cell in the CNS?
Glial cell
What are the two fundamental cells in nervous tissue?
Neurons:communication
Glial cells: support cells
A synaptically dense region composed of unmyelinated axons, dendrites, and processes of glial cells.
Neuropil
Is connective tissue integrated into the CNS?
NO NO NO NO
What is the primary function of a neuron?
Generates and propagates action potentials
Where on the neuron do action potentials propagate along?
The axon
What part of the neuron is responsible for receiving information from other neurons?
Dendrites
How do dendrites (dendritic spines) effect surface area?
Increases surface area
Nissl bodies are the same as what cellular component?
Rough endoplasmic reticulum, free ribosomes
Action potentials are generated between which parts of the neuron?
Between axon hillock and beginning of myelin sheath
Intermediate filaments that provide structural support to the cell in axons.
Neurofilaments
