3 types of muscle tissue
|
Smooth
Skeletal Cardiac |
|
Characteristcis of Smooth muscle
|
Single, fusiform, no stritations
Involuntary Mostly in walls of hollow visercal organs Very slow contraction |
|
Characteristics of Cardiac muscle
|
Branching chains of cells, uninucleate, striated with intercalated discs
Involuntary In the walls of the heart Slow contraction, faster depending on heart rate |
|
Characteristics of Skeletal muscle
|
Single, very long, cylindrical, multinucleate
Very obvious striations Voluntary Slow to fast contraction |
 What type of muscle tissue is this? |
Smooth
|
 What type of muscle tissue is this? |
Skeletal
|
 What type of muscle tissue is this? |
Cardiac
|
|
Contraction and shortening of muscles is due to:
|
The movement of microfilaments.
|
|
Where is the endomysium in skeletal muscle and what is its function?
|
Endomysium is a delicate connective tissue sheath that encloses a single muscle fiber
|
|
What and where is the perimysium in skeletal muscle fibers?
|
Perimysium is a coarse fibrous membrane that wraps a bundle of muscle fibers to form fascicles.
|
|
What is a fascicle?
|
A fascicle is a bundle of muscle fibers.
|
|
What and where is the epimysium in skeletal muscle tissue?
|
Epimysium is an even tougher "overcoat" of connective tissue that binds many fascicles together to form the whole muscle.
|
|
Put these in order:
Whole muscle Muscle fiber Fascicle |
Muscle fiber (wrapped by endomysium, bound together by perimysium to form) fascicles (bound together by epimysium to form) the whole muscle.
|
|
(Skeletal Muscle Attachments)
Epimysium blends into these two types of tissue: |
Tendons
Aponeuroses |
|
Tendons vs. Aponeuroses
|
Both blend with epimysium, BUT
Tendons are cordlike structures that attach muscle to bone, typically at rough bony projections that would tear more delicate muscle tissues Aponeuroses are sheetlike structures that attach muscles indirectly to bones, cartilage, or connective tissue covering. |
