Nervous Tissue Flashcards
1
Q
What is nervous tissue?
A
Considered to be “excitable” due to its ability to transmit electrical impulses
2
Q
What is the composition of nervous tisue?
A
Consists of neurons (cells that convey electrical impulses)
and a number of accessory cells called gilial cells
3
Q
How do neurons transmit their signals to other cells?
A
Through chemical messengers called neurotransmitters
4
Q
What are the functions of neuroglia?
A
-maintain physical structure of neural tissue
-repair neural tissue framework after injury
-performs phagocytosis
-provides nutrients to neurons
-regulate the composition of interstitial fluid surrounding neurons
5
Q
What makes up a neuron?
A
Dendrite, Cell body, Axon, Myelin sheath, neuron muscle synapse, muscle, axon terminals
