2. Visceral muscle
What tissue is this?
Cardiac muscle tissue
Where is this tissue found?
Walls of the heart (the “myocardium”)
What tissue is this?
Skeletal muscle tissue
Describe the myofibril arrangement in this tissue.
Dense, orderly arrangement producing dark striations
What tissue is this?
Smooth muscle tissue
Describe the “cell type” for this tissue
Elongated, tapered fibers arranged as bundles, sheets, or
cords
What tissue is this?
Skeletal muscle tissue
What degree of control do we have over this tissue type?
Voluntary control
What tissue is this?
Cardiac muscle tissue
What are two alternative names for this tissue?
1. Involuntary, striated muscle2. Heart muscle
What tissue is this?
Smooth muscle tissue
Describe the nuclear arrangement for this tissue.
One nucleus in the center of the cell
What tissue is this?
Cardiac muscle tissue
Describe the vascular supply for this tissue.
Dense capillary network, continuous supply
What tissue is this?
Skeletal muscle tissue
Where is this tissue found in the human body?
Usually attached to the bones of the skeleton on one or both ends.
What tissue is this?
Skeletal muscle tissue
Describe the nuclear arrangement for this tissue.
Multiple, peripheral nuclei
What tissue is this?
Smooth muscle tissue
Describe the vascular supply for this tissue.
Good blood supply, but highly variable
What tissue is this?
Skeletal muscle tissue
What microscopic “view” is seen in this picture?
Cross-section (short axis)
What tissue is this?
Cardiac muscle tissue
Describe the “cell type” for this tissue.
Short fibers which form a branching & weaving network
with intercalated discs
What tissue is this?
Skeletal muscle tissue
How does this muscle tissue rank against the other two for blood
supply?
Ranks 2nd
What tissue is this?
Smooth muscle tissue
Describe the contraction of this muscle tissue.
Rhythmic, powerful, yet slow to contract & relax
What tissue is this?
Skeletal muscle tissue
What is an alternative name for this muscle tissue?
Voluntary, striated muscle
What tissue is this?
Skeletal muscle tissue
What identifying characteristics (list primary & secondary) are
visible in this slide?
• 1. Primary – multiple, peripheral nuclei
• 2. Primary – long, cylindrical, parallel fibers
• 3. Secondary – dark striations
What tissue is this?
Cardiac muscle tissue
Describe the myofibril arrangement in this tissue.
Dense (but less than skeletal), orderly producing faintly visible
striations
What tissue is this?
Smooth muscle tissue
How does this muscle tissue rank against the other two for blood
supply?
Ranks 3rd
What tissue is this?
Skeletal muscle tissue
What microscopic “view” is seen in this picture?
Longitudinal section (long axis)
What tissue is this?
Cardiac muscle tissue
What are the “darker” lines called?
Intercalated discs
What tissue is this?
Skeletal muscle tissue
Describe the “cell type” for this tissue.
Long, cylindrical, parallel fibers arranged as bundles within
bundles
What tissue is this?
Cardiac muscle tissue
What degree of control do we have over this tissue type?
Involuntary control
What tissue is this?
Cardiac muscle tissue
Describe the nuclear arrangement for this tissue.
One (sometimes two in larger cells) nucleus in center of cell
What tissue is this?
Bloodvessel
Skeletal muscle tissue
Describe the vascular supply for this tissue.
Good blood supply, varies with activity
What tissue is this?
Cardiac muscle tissue
Describe the contraction of this muscle tissue.
Rhythmic, rapid, repeating, fibers show coordinated contraction
What tissue is this?
Smooth muscle tissue
Where is this tissue found?
Walls of Internal Organs
What tissue is this?
Skeletal muscle tissue
Describe the contraction of this muscle tissue.
Vigorous, short duration,fibers contract independently (fatigue
easily)
What tissue is this?
Smooth muscle tissue
Describe the myofibril arrangement in this tissue.
Least dense, random arrangement producing no visible
striations
What tissue is this?
Cardiac muscle tissue
How does this muscle tissue rank against the other two for blood
supply?
Ranks 1st

What is the most prominent identifying characteristic visible?
Intercalated discs
What tissue is this?
Skeletal muscle tissue
What is the “striped” or “banded” look seen in this slide called?
Striated or striations
What tissue is this?
Smooth muscle tissue
Name an organ in the body where this tissue can be found.
Walls of stomach, intestines, esophagus, bladder, uterus,
arteries, and more
What tissue is this?
Skeletal muscle tissue
The cell membrane of the tissue is called what?
Sarcolemma
What tissue is this?
Cardiac muscle tissue
Name an organ in the body where this tissue can be found.
Only found in the walls of the heart called the myocardium
What tissue is this?
Skeletal muscle tissue
What are these?
Multiple, peripheral nuclei
What tissue is this?
Skeletal muscle tissue
Name an organ in the body where this tissue can be found.
Name any muscle from the quiz lists such as biceps brachii,
trapezius, deltoid, etc.
What tissue is this?
Cardiac muscle tissue
Are there visible striations in this picture?
Yes
What tissue is this?
Skeletal muscle tissue
What is the structure between these arrows called?
The arrows point to the Z-lines. That makes what is between
them a sarcomere.
What tissue is this?
Cardiac muscle tissue
This tissue has parallel fibers, so why isn’t it skeletal muscle
