Skeletal Muscle Flashcards
How did skeletal muscle get its name?
These muscles are attached to and bring about the movement of the various bones of the skeleton
Describe the contraction of skeletal muscle tissue
The contraction of skeletal muscle tissue is very quick and forceful
What is the whole muscle enclosed in?
A sheath of connective tissue called the epimysium
What does the epimysium do?
It is a sheath of connective tissue that folds inwards into the substance of the muscle to surround a large number of smaller bundles, the fasciculi
What do fasciculi consist of?
The fasciculi consist of still smaller bundles of elongated, cylindrical muscle cells, the fibres
What do the fibres contain?
Each fibre has many nuclei
Describe the nuclei found in cylindrical muscle cells
The nuclei are oval in shape and are found at the edges of the cell
Describe the muscle fibres
The fibres have many alternating light and dark bands, giving them a striped or striated appearance
