Muscle Fiber
21
Q
Muscle Fibers are arranged into groups called .
A
Fascicles
22
Q
The muscle as a whole is covered by a connective tissue sheath called
A
Epimysieum
23
Q
Each fasicle is surrounded by a connective tissue sheath called
A
Perimysium
24
Q
Individual muscle fibers are surrounded by their extracellular matrix known as the
A
Endomysium
25
Muscle fibers are wrapped by their plasma membrane known as the
Sarcolemma
26
The muscle fiber's cytoplasm
Sarcoplasm
27
The sarcoplasm is filled with organells called
myofibrils
28
protien subunits in myofibrils are called
Myofilaments
29
The modified endoplasmic reticulum in muscle cells is called the
sarcoplasmic reticulum
30
An inward extension of the sarcolemma is known as a
T-Tubule
31
What are the two types of myofilaments involved in contraction?
thick and thinfilaments
32
The arrangment of the thick and thin filamnets within the myofibrils is what gives skeletal muscle its characteristic appearance
striated
33
The dark regions of the striations
A bands: because this is where the thick and thin filaments overlap
34
The light regions of the striations
I Bands; because they only contain thin filaments
35
Dark line bisecting the I band
Z disc
36
Defined as the space from one Z disc to the next Z disc
Sarcomere
37
Fundamental unit of contraction
