MIDTERM: MUSCLE TISSUE Flashcards
are bands or bundles of fibrous tissues in human body.
Muscles
The unit of a muscle tissue is a ____
cell
The unit of a muscle tissue is a cell, often referred as ______
muscle fiber
The term “___” is used here in contrast to a ________
fiber
connective tissue fiber
Every muscle fiber is surrounded by a basal lamina called the ______
Endomysium
Its plasma membrane is often called the _______
sarcolemma
Its plasma membrane is often called the _______a nd its cytoplasm is given a special name ______
sarcolemma / sarcoplasm
contains bundles of very long, multinucleated cells with cross striations
Skeletal muscle
Also has cross striations and its composed of elongated often branched cells bound to one another as structures
Cardiac muscle
Also has cross striations and its composed of elongated often branched cells bound to one another as structures called _______
intercalated disc
unique to cardiac muscle
intercalated disc
consist of collections of fusiform cells that lack striations and have slow, involuntary contractions
Smooth muscle
A muscle has the ability to conduct an action potential
conductivity
when stimulated, the muscle will react
irritability
a muscle can be shorten or produce tension between its ends
contractility
A muscle can return to resting properties after contraction
relaxation
a muscle can be stretched by a force outside of the muscle itself
distensibility
the muscle will resist elongation and will return to its original position after passive or active elongation
elasticity
differentiate the muscle according to
location and the number of nucleus
shape of the muscle fibers
presence and absence of striation
