Muscles and Nerve Tissue
Muscle Tissue
•
•
Long, narrow cells specialized to
contract
Cells named fibers are arranged in
bundles and surrounded by c.t.
Skeletal
• Also called voluntary
or striated (striped)
• Attach to bones
• Multinucleated
• nuclei located near
cell membrane
• Cells contract when
stimulated via nerve
Smooth
•
•
•
•
•
also called involuntary
or visceral
Controls stomach,
uterus, intestines
each cell has one
central nucleus
each cell is spindle
shaped
cell has NO striations
Cardiac

Heart muscle
Striated and involuntary
Cells are branched and
interconnected
Cells may have one or
more nuclei
Cells join at intercalated
discs
Tissue is not stimulated
via nerves but has its
own “pacemaker”
Nerve Tissue

Functions;
Receive stimuli from other cells
Transmit impulses to other cells
Controls the action of muscles and glands
Types of cells in tissue
1. neurons- transmit and receive impulse
2. glial cells-supporting cells
1= cell body
2= dendrites
3-4= axons
Neuron
